Our complete line of worms and worm gears could be worm gear box assembly ordered through the EP Gear Guaranteed Same Day time Shipment Plan for the quickest delivery possible.
Product Features
90°, nonintersecting shaft applications answer highly specialized power transmission needs.
Our worm gears offer the smoothest, quietest form of gearing.
They provide high-ratio speed reduction in minimal spaces.
Their efficiency is easily increased by reducing ratios.
With some ratios, there is resistance to back driving.
Obtainable from 48 DP to 3 DP
Stocked as single, double and quad start configurations

Because the performance of a worm gear drive depends upon the lead angle and amount of starts on the worm – and because increased performance is always an objective, the ratio ought to be kept as low as possible. To run correctly, worms and worm gears used together will need to have the same diametral pitch and threads.

Worms & Worm Gears
EP Gear’s worms and worm gears provide a highly effective answer for power tranny applications requiring high-ratio quickness reduction in a limited space using right angle (90°), nonintersecting shafts. When properly applied, worms and worm gears supply the smoothest, quietest kind of gearing.

The primary advantage of worm gears is their ability to provide high reduction ratios and correspondingly high torque multiplication. They can also be utilized as acceleration reducers in low- to moderate-velocity applications. And, because their decrease ratio is based on the amount of gear teeth alone, they are more compact than other styles of gears. Like fine-pitch business lead screws, worm gears are usually self-locking, which makes them ideal for hoisting and lifting applications.
