Piston air compressor

What is a piston air compressor?
A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to provide gases at ruthless. … The heat exchangers that are found in a standard piston compressor are removed as the heat is taken out in the cylinder itself where it really is generated.
How will a piston air flow compressor work?
Like a little internal combustion engine, a conventional piston compressor includes a crankshaft, a connecting rod and piston, a cylinder and a valve head. … As the piston movements down, a vacuum is established above it. This enables outside atmosphere at atmospheric pressure to press open the inlet valve and fill up the region above the piston.
What’s piston displacement of a compressor?
Piston displacement of the reciprocating compressor is the volume swept by the piston within the cylinder in unit period and it is same as the capability of the compressor.
What kind of oil does a piston air compressor use?
Typically, compressor manufacturers will recommend a 20 weight or 30 weight (non-detergent) compressor oil. You may use a typical or synthetic blend compressor oil, if the manufacturer states you’ll be able to do therefore but adhere to the manufacturer’s recommendations in order to avoid voiding the warranty.
Pressure Lubricated Reciprocating/Piston Surroundings Compressors
A reciprocating air flow compressor is a positive displacement compressor that runs on the crankshaft-driven piston and cylinder to compress the atmosphere. A single-stage reciprocating piston compressor works by drawing the air into the cylinder where it is compressed in a single piston stroke of approximately 120 PSI and delivered to a storage container. A two-stage compressor contains an additional step where in fact the surroundings is compressed by a second, smaller piston to a pressure of up to 175 PSI.
Our premium, top-of-the-line pressure lubricated piston atmosphere compressor may be the QR-25. It’s a heavy-duty compressor that’s pressure lubricated in all critical areas and delivers up to 25 hp. Available in solitary- and two-stage versions, the QR-25 is designed to operate at slower speeds and is equipped with intake loaders that reduce work. The tough cast iron construction ensures a long life span, less downtime and much easier maintenance. Other important features include loadless beginning, a manually reversible essential oil pump and rebuildable components. Viewed as the industry standard in piston compressor technology, the functionality of Quincy’s ER-25 is legendary.

Greenhouse gearbox

To keep up the delicate environment in the greenhouse, climate control systems certainly are a necessity. Several mechanical systems can be used in this respect; however cup vent drive systems tend to be the most popular. we has been providing solutions for this kind of application for 20 years. The drive program consists of a central gearmotor connected to a 40:1 right angle reducer with dual output shafts. These OP shafts connect to long jack shafts that spread over the roof line of the greenhouse connecting to multiple rack and pinion mechanisms that open and close large cup home window panes in the ceiling for temperature control.
Depending on the size of the application (amount of the shafting, quantity and weight of the screen panes) we offers two gearmotor solutions from a modified version of their 200 series parallel shaft range – 1/5 HP and 1/20 HP. The application form Is generally intermittent in use; however the motors are rated continuous since the glass pane home windows could potentially be under continuous, subtle adjustment during the day.

Today, the company has grown into an industry head for fractional horsepower electric motor, essential gearmotor and equipment reducer products by implementing innovative lean production processes, top notch engineering and customer support groups driven by their style philosophy; allowing us to consistently expand its products with new motion control and power tranny solutions.
AC motors and equipment motors include single-phase motors used with a single-stage AC power supply and three-phase motors used with a three-stage AC power. A single-phase motor can be operated by simply linking it to a single-phase power supply via the provided capacitor. A three-phase motor does not need a capacitor. All you need is to connect the motor directly to a three-phase AC power supply.

Efficiency of a swiftness reducer is an essential selection factor that is often overlooked.In many cases, high-efficiency gearing cuts the expense of drives and their operation
Because they are widely used with agricultural gearbox industrial equipment, quickness reducers and gearmotors can significantly effect your drive costs. Therefore, you should know how efficiently the various types of reducers use incoming motor capacity to drive a load.
Though reducer efficiency may vary slightly from one manufacturer to another, the way in which the gears intersect and mesh mainly determines speed reducer efficiency.
The worm equipment and worm wheel have nonintersecting, perpendicular axes, and the meshing action between gears occurs over a relatively large get in touch with area. This meshing action consists mainly of a sliding motion that creates friction between the gears.

Right Angle Gearbox
Right angle gearboxes are characterized by the fact that the drive shaft and the output shaft are organized at an angle of 90 degrees. With respect to the gearbox type, the axes can intersect in a plane or cross on two parallel planes, which results in an axis offset.
Right angle gearboxes are noticed with different types of gear teeth or a mixture of different gearing types. The most popular single-stage gearbox types are bevel and worm.
Due to the high single stage ratios and the reduced efficiency level, worm gears can achieve a self-locking effect. With worm gears it is also possible to have a hollow shaft as the drive shaft.
Bevel gearboxes include different types of gearing. Bevel gearboxes with intersecting axes are recognized using bevel gearing with directly, helical or spiral tooth. Hypoid gearboxes possess helical bevel gearing with which the axes cross with an axis offset. The bandwidth of technically sensible ratios with that your bevel gear stage could be realized is larger with hypoid gearboxes than with the classical bevel gear teeth.
Bevel gearboxes can also be combined with additional gearbox types. A regular software in this respect is the mixture with a planetary gearbox, whereby the planetary gearbox could be linked upstream or downstream. This results in a wide range of overall multiplication factors and wide range of uses in many industrial applications.
The efficiency level of bevel gearboxes is typically lower than that of coaxial spur gearboxes, particularly compared to planetary gearboxes. This is because the bevel gear stage generates a high degree of axial pressure and radial pressure, which has to be absorbed by suitable bearings. This increases the power reduction, which is particularly significant in the drive stage of the gearbox.
The operating noise and the transmittable torques of classic bevel gearboxes are also lower than with single spur equipment teeth. Hypoid gearboxes, on the other hand, are extremely noisy and may transmit huge amounts of torque, but a considerable amount of bearing load occurs in the bevel gear stage of these gearboxes.
In summarizing, the right angle gearbox is generally used when the amount of installation space in the application form is bound, or an angular arrangement between your drive and the output is necessary by the application. They are also used in instances where the input shaft needs to be hollow in order to business lead through lines or use clamping sets.
The benefits of right angle gearboxes:
Use when set up space is limited
Compact design
Can be coupled with other styles of gearbox
Quiet and high amount of torque when using hypoid gearboxes
Version with hollow shaft possible
The disadvantages of right angle gearboxes:
Complex design
Lower effectiveness level than planetary gearbox
Cheaper torques in single-stage ratio range

Over the years we’ve received questions about nearly every part of the gearbox selection procedure. One of the queries we’ve had a few times is, “Exactly what is a right-position gearbox or a right-angle drive?” Or, more particularly, “How is a right-angle gearbox or drive different from a rate reducer or other types of gearboxes?”
First, let’s focus on some basic terminology. It is not uncommon for the terms “gearbox”, “drive” and “acceleration reducer” to be used interchangeably.
A gearbox is any device that uses a gear teach to transmit torque/rpm and anything that uses a gear to transmit torque/rpm is a gearbox.
A right-angle drive is a mechanism with a gear train that may transmit torque/rpm 90 degrees, to carefully turn a corner
A equipment reducer is a system with a gear teach that may reduce rpm output. Due to decreasing rpm is raising torque at the same ratio velocity is reduced.
A gear box can also be a speed increaser
The kind of gear used in the apparatus box defines it as the right angle or an inline drive.
A worm equipment drive is a right-angle drive since is a bevel gear
A spur gear drive is inline
A helical equipment is inline but may also be a right-angle drive
So, what is a right-angle gearbox?
A right-angle gearbox is a gearbox with a right-angle change in direction of the shaft. It’s rather a 1 to 1 1 ratio or a multiple of just one 1 such as for example 2:1 or 15:1. If the ratio is 1:1 it is a right-angle drive. If the ratio can be greater than 1:1 it really is a right-angle swiftness reducer.

2.1 Product introduction High-velocity gearboxes designed and manufactured in Ever-power are designated mainly for power generation industry, compressor and pump applications. The manufacture is carried out on the modern machine tools and gearboxes are assembled using personal components or components given by European manufacturers. All products undergo comprehensive planetary gearbox Testing on a dynamic test bench. The design and gear power calculation are performed according to API 613 5th Edition and AGMA 6011*. Product types: RS and RU gearbox type is made to withstand forces from meshing of dual helical gears. They aren’t made to withstand any external axial or radial load. R1T and R2T gearbox type is made to withstand forces from meshing of single helical gears and exterior axial and radial load. The transmission of external axial load from HS shaft to LS shaft is by way of thrust collars. The gearbox is usually self supporting and doesn’t need any reinforcement. It has a foot flange for mounting to a base and jack bolts (levelling bolts) for easy installation. The gearbox will not require any unique maintenance. It is suggested to change the essential oil on regular basis or when changing the climate conditions – start to see the Operating Manual for details. Regular gearbox is altered for high speed operation in the temperature range between -50 / +50°C provided the oil preheating at low temperature ranges and oil cooling at high temperature ranges. Should the gearbox be managed in hazardous area or under other particular conditions, it has to be contractually agreed. The typical gearbox efficiency is usually higher than 98,5%. Total efficiency depends on plenty of factors, such as for example mesh losses, bearing losses, windage losses etc. Ever-power is competent to prepare personalized solution to raise the gearbox effi ciency up to 99,5%. mesh losses gearing is certainly sized based on the transmitted power. Power is definitely distributed by a customer. It is not possible to lessen mesh losses considerably, however Ever-power aims to improve the losses to attain the best compromise as well as gear life, strength and NVH behaviour. bearing losses these losses have the biggest impact on the gearbox effectiveness. It is necessary to design and size the bearing correctly. windage losses windage losses have got big influence on the gearbox performance if the apparatus circumferential velocity is high. It is possible to decrease these losses (up to approx 50%) utilizing the windage cover. additional losses gearbox efficiency is also affected by the essential oil pump losses (if used), oil injection loss etc.
2.3 Key specialized features Turbo Gear Units Catalogue © Ever-power Industry a.s. 2016, EN1604 Main Gearbox Components 2.3.1 Housing The housing consists of 2 parts: the upper and the low case. It is fabricated steel structure. The housing is optimized by CAE solutions to ensure once and for all stiffness, low sound emissions, excellent cooling properties and minimal weight. In the lower part there are foot for fixing the gearbox to the foundation equipped by jack bolts and with provision for mounting of earthing screw (if the gearbox is set to the hazardous area). There is also located the oil input/output fl ange and provision for temperature detectors conduction to the junction container. In the upper component there is an inspection cover, looking at the correct lubrication of meshing gears, a breather and provision for vibration probes. Split face of the casing is definitely horizontal, parallel to shaft axis. Both parts are linked by bolts and fi xed by dowel pins. 2.3.2 Shafts and gears Both shafts are forged items. HS shaft is forged in one piece along with gearing. LS shaft and the apparatus are forged separately and the apparatus is heat assembled on the shaft. The backsplash band is usually forged in one piece with the shaft or high temperature assembled. Both gears are ground to high precision. The teeth fl anks of HS pinion have got special modifi cations to reduce the sound level and compensate the defl ection of shafts because of large load. A hunting tooth combination is present for mating gears when a tooth on the pinion does not repeat contact with a tooth on the apparatus wheel until it has contacted all the other gear wheel the teeth. The shape of shafts ends depends on customer’s request (cylindrical, tapered, fl anged etc.). Both shafts are dynamical balanced according to ISO 1940 or API 613. 2.3.3 Bearings Solely hydrodynamic bearings with an increase of sliding faces are used because of high speeds and bearing load. These bearings are divided into bearings with: • fi xed geometry – there is no motion of sliding faces • tilting pads – sliding faces are moving
LS (low velocity) shaft is generally placed in plain journal bearings with cylindrical clearance (fi xed geometry). Among the bearings is radial (on the non-driving end) and the other one (on the generating end of the shaft) is mixed radialaxial bearing. The design and calculation of the bearings are performed according to the latest strategies. Bearings on HS (high speed) shaft are usually tilting pad type due to high acceleration and pitchline velocity and both of these are radial bearings. Tilting pad bearings will often have 4 or 5 5 pads and static load direction goes either on one pad or between pads. Lubrication of the bearings could be reached by overflowing the space between pads or essential oil injection between pads by way of a number of nozzles which also protects pads against circumferential movement. When essential oil injection is used you’ll be able to decrease friction losses substantially. These bearings have the highest resistance against rotor instability because they do not generate any load causing instability

Drive shaft

Drive shaft
Ever-Power offers telescopic drive shafts in a variety of design types, such as Heavy Duty, Stainless Steel and Leveler Strength.

Drive shafts, also called articulated shafts, are shafts that include two universal joints. The simplest kind of drive shaft has a joint at each end. The configuration is essentially an extended double joint for overcoming distances and offsets between the drive and the influenced load. Drive shafts provide a solution for bridging angular misalignment.
Telescopic Drive Shafts
Drive shafts can contain a telescopic middle factor that enables quicker and simpler repositioning than feasible with a rigid two-joint shaft. They enable easy length adjustment in axial misalignments.
Spring-Loaded, Quick-Change Shafts for Reducing Downtime
Spring-loaded drive shafts contain two back-to-back single universal joints connected with a spring-loaded intermediate shaft. It allows the drive shaft to end up being quickly removed and substituted without equipment. Pinning of outer yokes is not needed because the spring stress on the intermediate shafts holds the quick-modify universal joint protect at each end.
Fail-Safe Stop Solution
Spring-loaded drive shafts can be customized to add a fail-secure solution. If the application very seriously exceeds the joint’s rated torque capability, the drive shaft could be designed to fail and stop in a safe style, without damaging the electric motor.
We uses the best products and resources to meet up all agricultural drive shaft requirements. Drive Shafts, Inc. likewise carries an extensive line of plastic-type driveline shielding from World Shield.
PTO belt driven centrifugal pumps were initially introduced in 1964 and enabled the applicator to install centrifugal pumps directly on 540 RPM and 1000 RPM tractor PTO shafts. The easy, yet durable design of the PTOC pump has withstood the test of time while many efforts at imitation have come and gone.

The key to success of the belt powered pump has been the Planting season Loaded Idler. The idler maintains appropriate belt tension which minimizes the load on the pump bearings. More importantly, the idler will help absorb the shock of PTO engagement that can destroy cog belts or gears.

Version PTOC belt driven pumps are easy to operate and maintain. Belts can be changed in the field with bare minimum downtime and at small cost. Maintenance features likewise incorporate sealed ball pto shaft bearings and a easily replaceable mechanical seal. The belt guard provides complete policy of the pulleys, shaft and belt. All PTO driven pumps are equipped with a stainless shaft and wear band for excellent corrosion level of resistance.
We just need to know what series you want, the yoke you want on each end, what size you want the driveshaft overall compressed, and we’ll take treatment of the rest.

PTO gearbox

PTO Gearboxes
PTO or Speed up gear boxes are mainly applied to agricultural tractors where more hydraulic power is required than the program on the tractor can offer.
The quick release coupling upon the gear box attaches to the tractor PTO shaft and steps up the PTO speed to 1 much more suitable for the efficient speed of a hydraulic pump. A Gear pump is suited to the other part of the apparatus box.
The Power Take-Off, most commonly described by its acronym, PTO, is a common kind of mechanical power delivery in the mobile machine market. The PTO can be a way of transferring high power and torque from the engine (generally via the transmission) of trucks and tractors. In mixture with gearboxes and pump mounts, almost any kind of mechanical power transmission is possible.
There are three common power take-off methods in the mobile machine market; tractor style, truck transmission design and engine crankshaft-driven, although the latter is not commonly referred to as a PTO. The pto gearbox crankshaft-driven approach to power transmission is frequently utilized for hydraulic pumps mounted to the front of an on-highway pickup truck, like a plow/spreader or cement mixer. A little shaft with U-joints attaches to a yoke coupler to turn the pump. This configuration of drive isn’t generally known as a PTO, however.
The tractor PTO goes back pretty much so far as tractors. The majority of early PTOs were driven from the transmitting, which being located at the back of the tractor, allows for easy location of an result shaft. The transmission kind of PTO is engaged when the tranny clutch can be engaged, and can be coupled directly to transmission, so that when the clutch is depressed, the PTO isn’t driven.

If the transmission is driving the wheels, then the transmission PTO is turning. This also means the apply can backward-power the tranny aswell when the clutch is usually depressed, such as for example down a hill or if the attachment includes a system with high rotational inertia, resulting in surging of the drive wheels. This was avoided by the addition of a devoted overrunning clutch for the PTO, which prevents torque from getting applied in the opposite direction.

A live PTO often runs on the tranny clutch with two phases. The first stage of the clutch works the driven portion of the transmission, and the next stage of the clutch settings the engagement of the PTO. This method allows independent control of the transmission, to ensure that the PTO maintains operation regardless of transmitting clutch activity, including stopping of the tractor itself. For a tractor with a mower attachment, for example, this is the very least requirement; you can’t have the mower turn off when you feather the clutch up a hill and around a tree.

Spur gear

Spur gears or straight-cut gears will be the simplest kind of gear. They contain a cylinder or disk with the teeth projecting radially. Although teeth aren’t straight-sided (but generally of special form to achieve a continuous drive ratio, generally involute but less generally cycloidal ), the edge of each tooth is directly and aligned parallel to the axis of rotation. These gears mesh together correctly only if fitted to parallel shafts.[ Simply no axial thrust is created by the tooth loads. Spur gears are great at moderate speeds but tend to become noisy at high speeds.
Spur gears will be the most easily visualized common gears that transmit movement between two parallel shafts. Because of the shape, they are categorized as a kind of cylindrical gears. Because the tooth surfaces of the gears are parallel to the axes of the installed shafts, there is no thrust force generated in the axial direction. Also, because of the simple production, these gears could be made to a high degree of precision. On the other hand, spur gears have a disadvantage for the reason that they very easily make noise. Generally speaking, when two spur gears are in mesh, the gear with more the teeth is called the “gear” and the one with the smaller number of the teeth is named the “pinion”.
Among the many professional spur gear manufacturers and suppliers in China, we warmly welcome you to get or wholesale mass spur gear manufactured in China here from our factory.
Spur gear tooth are produced by either involute profile or cycloidal profile. The majority of the gears are produced by involute profile with 20° pressure angle. When two gears are in mesh at one quick there is a chance to mate involute part with non-involute portion of mating equipment. This phenomenon is known as “interference” and occurs when the amount of teeth on small of the two meshing gears is significantly less than a necessary minimum. To avoid interference we can possess undercutting , but this is simply not a suitable solution as undercutting prospective customers to weakening of tooth at its foundation. In this situation Corrected gears are used. In corrected gears Cutter rack is definitely shifted upwards or downwards.
Spur gears will be the most easily visualized common gears that transmit movement between two parallel shafts. Because of the shape, they are categorized as a kind of cylindrical gears. Since the tooth areas of the gears are parallel to the axes of the mounted shafts, there is absolutely no thrust force generated in the axial direction. Also, due to the ease of production, these gears could be made to a high degree of precision. On the other hand, spur gears possess a disadvantage for the reason that they easily make noise. In most cases, when two spur gears are in mesh, the gear with more tooth is named the “equipment” and the one with the smaller number of teeth is called the “pinion”.
The unit to point the sizes of spur gears is often stated, as specified by ISO, to be “module”. Recently, it is usual to set the pressure angle to 20 degrees. In commercial machinery, it is most common to use a part of an involute curve as the tooth profile.
Even though not really limited to spur gears, profile shifted gears are utilized when it is required to adjust the guts distance slightly or to strengthen the gear teeth. They are produced by adjusting the distance between your gear cutting device called the hobbing device and the gear in the production stage. When the shift is definitely positive, the bending strength of the gear increases, while a negative shift slightly reduces the center distance. The backlash is the play between the the teeth when two gears are meshed and is necessary for the clean rotation of gears. When the backlash is definitely too big, it leads to increased vibration and noise as the backlash that is too little leads to tooth failure because of the lack of lubrication.
All Ever-power spur gears have an involute tooth shape. In other words, they are involute gears using area of the involute curve as their tooth forms. Looking generally, the involute form is the most wide-spread equipment tooth form because of, among other factors, the capability to absorb small center distance errors, very easily made production equipment simplify manufacturing, thicker roots of one’s teeth make it strong, etc. Tooth shape is often referred to as a specification in drawing of a spur equipment as indicated by the height of teeth. In addition to standard complete depth teeth, extended addendum and stub tooth profiles can be found.
Ever-power’s spur gears, which are designed to transmit motion and power between parallel shafts, are the most economical gears in the power transmission industry.
We offer both 14 1/2° and 20° PA (pressure angle), involute, and full-depth system gears. 20° PA is generally recognized as having an increased load carrying capacity; however, 14 1/2° PA gears are used extensively aswell. This is because the lower pressure angle reduces change in backlash because of center distance variation and concentricity mistakes. The 14 1/2° PA also offers a higher contact ratio for smoother, quieter operation.
Ever-power spur gears can be found through our Guaranteed Same Day time Shipment from our world class manufacturing middle in Hangzhou, China. Many different gears with a number of bore sizes, keyways, and setscrews are routinely in stock, but if the particular bore/keyway/setscrew combination needed is not readily available, our machining professionals can transform any non-hardened gear and deliver it within 24 hours.

Gear rack

Racks are portions of a cylindrical disk with an infinite radius which has involute shaped the teeth cut into its face. Racks mate solely with spur gears which have the same module, pressure position and preferably face width. EVER-POWER offers equipment racks in many components, configurations, modules and lengths. One exclusive feature of our racks is that most are given finished ends. This type of production permits multiple racks to be butted, end-to-end, to produce one continuous length of rack. Many of the products that people offer enable secondary operations such as reduction of the length, the adding of tapped holes, or the use of heat therapy. Our offering also includes products which have already had a few of these secondary functions completed. These products are recognized by a “J” in their part number plus they are offered within 10 calendar times.
The straight tooth cylindrical gear that the radius of the pitch cylinder is infinite and in a bar form is named a gear rack. If it’s sorted by the positions of the apparatus shafts, it is one of the parallel shaft category. The spur gear that meshes with a equipment rack is generally called a pinion.
Besides equipment racks with straight series the teeth, there are helical racks that have slanted teeth. Helical equipment racks are paired with helical gears, but because of the slant of the tooth direction, as in helical gears, the mesh creates axial thrust forces.
Among the apparatus racks’ main applications are machine equipment and transport devices so when the applications involve transmitting linear motions, they are generally compared with ball screws. In those situations, the main benefits of gear racks could be named this kind of as being able to meet a heavier load through the use of larger modules and having no size limitation by connecting gear racks with completed ends. However, an example of the disadvantages of equipment racks contains the occurrence of backlash.
When manufacturing equipment racks, because of their bar shape, bending often results. In these cases, corrective processes using presses are often employed.
As for the type of gear racks, aside from the usual bar form, there are circular racks in which the cross sections are circular and flexible racks which can be bent into totally free curve shapes.

Gear racks
Gear racks are utilized to convert rotating motion into linear movement. A gear rack has straight the teeth cut into one surface area of a sq . or round portion of rod and operates with a pinion, which is usually a small cylindrical gear meshing with the apparatus rack. Generally, equipment rack and pinion are collectively called “rack and pinion”. There are several ways to use gears. For example, as shown in the picture, a gear is used with the apparatus rack to rotate a parallel shaft.
To provide many variants of rack and pinion, Ever-power has various kinds of gear racks in share. If the application takes a long length requiring multiple equipment racks in series, we have racks with the tooth forms correctly configured at the ends. These are described as “gear racks with machined ends”. When a equipment rack is produced, the tooth cutting process and the heat treatment process can cause it to try & go out of true. We are able to control this with special presses & remedial processes.
There are applications where in fact the gear rack is stationary, as the pinion traverses and others where the pinion rotates on a fixed axis while the gear rack moves. The previous is used broadly in conveying systems as the latter can be utilized in extrusion systems and lifting/lowering applications.
As a mechanical component to transfer rotary into linear movement, gear racks are often in comparison to ball screws. There are pros and cons for using racks in place of ball screws. The advantages of a equipment rack are its mechanical simplicity, huge load carrying capacity, no limit to the distance, etc. One disadvantage though is the backlash. The advantages of a ball screw are the high precision and lower backlash while its shortcomings are the limit in duration due to deflection.
Rack and pinions are used for lifting mechanisms (vertical movement), horizontal movement, positioning mechanisms, stoppers and also to let the synchronous rotation of several shafts in general industrial machinery. However, also, they are found in steering systems to change the direction of vehicles. The characteristics of rack and pinion systems in steering are as follows: simple framework, high rigidity, small and lightweight, and exceptional responsiveness. With this system, the pinion, installed to the steering shaft, is meshed with a steering rack to transmit rotary movement laterlly (switching it to linear movement) so that you can control the wheel. In addition, rack and pinions are used for many other purposes, such as toys and lateral slide gates.
