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

Because the effectiveness of a worm gear drive depends upon the lead angle and amount of begins on the worm – and because increased performance is always a goal, the ratio should be kept as low as possible. To run correctly, worms and worm gears utilized together must 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 quickness reduction in a limited space using right angle (90°), nonintersecting shafts. When properly applied, worms and worm gears supply the smoothest, quietest type 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 used as rate reducers in low- to moderate-velocity applications. And, because their decrease ratio is based on the amount of gear teeth alone, they are smaller sized than other styles of gears. Like fine-pitch business lead screws, worm gears are typically self-locking, making them ideal for hoisting and lifting applications.

Although the sliding contact decreases efficiency, it provides very quiet operation. (The use of dissimilar metals for the worm and equipment also plays a part in quiet operation.) This causes worm gears ideal for use where noise should be minimized, such as in elevators. Furthermore, the usage of a softer materials for the gear implies that it can absorb shock loads, like those experienced in weighty equipment or crushing machines.
