Product Features
90°, nonintersecting shaft applications solution highly specialized power transmitting needs.
Our worm gears provide smoothest, quietest type of gearing.
They provide high-ratio speed decrease in minimal spaces.
Their efficiency is easily increased by lowering ratios.
With some ratios, there is resistance to back driving.
Obtainable from 48 DP to 3 DP
Stocked as single, dual and quad start configurations

Because the efficiency of a worm equipment 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 only possible. To run properly, worms and worm gears used together will need to have the same worm gear box assembly diametral pitch and threads.

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

The primary benefit of worm gears is their capability to provide high reduction ratios and correspondingly high torque multiplication. They may also be utilized as speed reducers in low- to medium-acceleration 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 lead screws, worm gears are usually self-locking, making them perfect 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 procedure.) This makes worm gears ideal for use where noise should be minimized, such as in elevators. Furthermore, the use of a softer materials for the gear means that it could absorb shock loads, like those skilled in heavy equipment or crushing devices.
