Product Features
90°, non-intersecting shaft applications solution highly specialized power tranny needs.
Our worm gears offer the smoothest, quietest form of gearing.
They offer high-ratio speed reduction in minimal spaces.
Their efficiency is easily increased by reducing ratios.
With some ratios, there is level of resistance to back driving.
Obtainable from 48 DP to 3 DP
Stocked as single, double and quad start configurations

Because the effectiveness of a worm equipment drive depends upon the lead angle and quantity of starts on the worm – and because increased efficiency is always a goal, the ratio ought to be kept only possible. To run properly, worms and worm gears utilized together will need to have the same diametral pitch and threads.

Worms & Worm Gears
EP Gear’s worms and worm gears provide an effective answer for power transmitting applications requiring high-ratio velocity reduction in a restricted space using right angle (90°), non-intersecting shafts. When properly used, worms and worm gears provide the smoothest, quietest form of gearing.

The primary benefit of worm gears is their ability to provide high reduction ratios and correspondingly high torque multiplication. They may also be employed as quickness reducers in low- to medium-rate applications. And, because their decrease ratio is founded on the amount of gear teeth alone, they are more compact than other types of gears. Like fine-pitch lead screws, worm gears are usually self-locking, making them perfect for hoisting and lifting applications.
