Product Features
90°, non-intersecting shaft applications solution highly specialized power transmitting needs.
Our worm gears offer the smoothest, quietest type of gearing.
They offer 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 efficiency of a worm equipment drive depends on the lead angle and number of begins on the worm – and because increased effectiveness is always a goal, the ratio should be kept only possible. To run properly, worms and worm gears used 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 tranny applications requiring high-ratio acceleration reduction in a limited space using right angle (90°), nonintersecting shafts. When properly used, worms and worm gears supply the smoothest, quietest form of gearing.

The primary benefit of worm gears is their capability to provide high reduction ratios and correspondingly high torque multiplication. They can also be utilized as rate reducers in low- to medium-quickness applications. And, because their reduction ratio is founded on the amount of gear teeth by itself, they are smaller sized than other types of gears. Like fine-pitch business lead screws, worm gears are typically self-locking, making them well suited for hoisting and lifting applications.

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