Ever-Power worm gearboxes have earned a popularity to be an industry benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-art technology, all and will be offering worm gearboxes are inexpensive prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the market. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low acceleration gear ratio. Being basic and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively bigger) and its own body is normally quite lengthy in the axial path. The gears in these gearboxes can be right or left-handed dependant on the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or double), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a type of interlocking gear composed of a worm shaft and worm wheel. The worm is definitely shaped like a screw and the worm wheel is definitely a kind of gear machined to have a tooth profile with the same configuration.
The procedure of a worm gear is similar with that of a bolt and nut. The principle is equivalent to a nut that has been fixed to ensure that it cannot rotate and therefore progresses in the axial direction when the bolt is usually turned.
The design of a worm gear is thought of through the relationship between your rack and spur gear on the center plane of the worm wheel.
Features
High reduction ratio One rotation of the worm rotates the worm wheel by one tooth. Because of this, in a 1 speed reduction gears, the wheel could be manufactured therefore that it'll be rotated 1/60 (1/120 in unique applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This characteristic makes it possible to layout the turning tranny direction at the right angle.
The arbitrariness of the rotation direction The screw direction of the worm could be clockwise or counterclockwise (generally clockwise). It is possible to change the rotation direction of the worm wheel by changing the screw direction.
A wide variety of shaft layouts The wide variety of shaft layouts is among the top features of interlocking gears.For instance, right shaft output, remaining shaft output, dual shaft input and dual shaft output, etc., combine for a complete of 14 types (Body 2) and, if attachment orientations are included, it is possible to select from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is characteristic since the contact is definitely linear and the relative slide is excellent. In comparison to rolling power transmission, sound and vibration are extremely low. Because of this, this technology is utilized to drive medical equipment, elevators and escalators, etc.

Key points when selecting a worm reduction gears
Selection
When selecting a worm reduction gears, the procedures for selecting the correct gear are described in the manufacturer catalogs and the series and models ought to be selected according to those procedures. Particular care ought to be taken in important areas such as for example selecting the strain index, calculating the overhang load and examining the heat rated capability from the manufacturer.
Cautions during use
When using a worm decrease gears, the heat produced during the initial period of use is high and running-in operation at 1/4, 1/2 and 3/4 of rated torque for eight hour periods is paramount to sufficiently achieving the performance of the worm reduction gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it is necessary to improve the lubricating oil and also to change the lubricating oil from then on about 1 time each year according to the operation manual provided by the manufacturer.

The worm reduction gears can be found in two series: X and H.
The series X, having a worm and worm wheel set, is available in versions XA with shaft and XF-XC with mounting provisions for motor.
Version XF (bell housing + coupling) offers great versatility to match a broad range of applications and higher efficiency than the compact collection XC, where the emphasis is on space effectiveness.
Series H offers the same features as series X with an extra plus: a spur gear pre-stage at the input end provides higher overall performance and a broader selection of ratios compared to the X series.
Frame sizes 110 and 90 feature a cast-iron casing cast enbloc, whereas smaller sizes use die-cast aluminium housings. The worm shaft is produced from casehardened and hardened alloy steel and ground-finished.
The worm wheel has a cast iron hub with cast bronze insert. Hollow result shaft comes as standard.
Broad range of possibilities:
second input, output flange, single or double extension output shaft, torque limiter with through cable, torque arm.
