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

Because the performance of a worm gear drive depends upon the lead angle and number of begins on the worm – and because increased performance is always a goal, the ratio ought to be kept only possible. To run properly, 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 swiftness reduction in a limited space using right angle (90°), non-intersecting shafts. When properly used, worms and worm gears supply the smoothest, quietest type 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 used as quickness reducers in low- to medium-quickness applications. And, because their decrease ratio is based 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, which makes them well suited for hoisting and lifting applications.

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