worm gear speed reducer

Single reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled compact drive. The proper angle set up of driving-to-driven machine requires a minimum of space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient electric motor speeds are decreased to slower speed requirements of several industrial machines in a single reduction.

The exclusive utilization of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and lengthy service existence. The hardened ground and polished alloy metal worm develops a easy, work hardened surface on the bronze equipment. Because of this worm gears wear in and worm gear speed reducer improve with extented service while various other gears are deteriorating. Ever-Power offers a wide collection of model configurations, sizes, ratios, and components from our standard products.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile products applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmitting of higher horsepower levels than are feasible with regular cast iron products. Extra heavy side plates connect the worm and equipment shaft bearing supports, assuring proper meshing of the gear under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom velocity and reversed engineered reducers for your application, be it a fresh project or a primary drop-in alternative to a competitor’s velocity reducer. Fabricated steel reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in alternative saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also incorporates a hardened, ground and polished alloy metal worm. This mixture develops a even, work-hardened mating surface of the bronze equipment which boosts with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides clean and quiet procedure and permits the possibility of large velocity reductions. These gears can be found from stock in a wide variety of ratios, from only 4:1 to as much as 3600:1. The compact design and construction allows worm gear reducers to be positioned in a comparatively small space. Thus, very high reductions in a restricted package size may be accomplished with this configuration. Our worm gear features the constant sliding tooth action between worm and one’s teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost in comparison with some other types of gearing.
The use of worm gearing extends across many industries including food, beverage and grain and has many applications. Some applications that make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one type of reduction gear package which consists of a worm pinion input, an output worm gear, and includes a right angle result orientation. This kind of reduction gear box is generally used to take a rated motor velocity and create a low speed output with higher torque worth based on the decrease ratio. They often can solve space-saving problems since the worm gear reducer is one of the sleekest decrease gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of rate reducer because they provide the greatest speed decrease in the smallest package. With a high ratio of speed reduction and high torque output multiplier, it’s unsurprising that many power transmission systems utilize a worm gear reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical assessment equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers two sizes of worm gear reducer, the SW-1 and the SW-5 and both can be found in a variety of ratios. The SW-1 ratios include 3.5:1 to 60:1 and the SW-5 ratios include 5:1 to 100:1. Both these options are produced with rugged compression-molded glass-fill up polyester housings for a long lasting, long lasting, light-weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a good or hollow output shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can endure shock loading much better than other decrease gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm velocity reducers. Worm gear reducers are utilized for speed decrease and raising the torque for electrical motor drives. You can choose to mount your NEMA electric motor to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you want a coupling for the result or input shaft find our coupling section for choosing the coupling. We offer four assemblies left hands and right hand and double output shaft and shaft insight and shaft result. Interchangeable with most worm gear manufactures.

Description
The HDR Series worm equipment reducers are found in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers can be found in direct or indirect drive, direct drive models are 56C or 145TC flange attach with either right, left or dual output shafts or a hollow bore result. The indirect drive versions are shaft input-shaft output boxes for make use of with sprocket or pulley drive systems. They offer an effective low priced solution to speed reduction and improved torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will have to determine the required torque and support factor for the application. Click on “Specs” above for a table that will assist in determining the service aspect. For service factors above 1.0, multiply the mandatory torque by the program factor.
