Product Features
90°, non-intersecting shaft applications solution highly specialized power tranny 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 decreasing ratios.
With some ratios, there is resistance to back driving.
Available from 48 DP to 3 DP
Stocked as single, dual and quad start configurations

Because the performance of a worm gear drive depends on the business 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 correctly, 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 worm gear box assembly provide a highly effective answer for power transmission applications requiring high-ratio quickness reduction in a restricted space using right angle (90°), non-intersecting shafts. When properly applied, worms and worm gears provide the smoothest, quietest type of gearing.

The primary advantage of worm gears is their capability to provide high reduction ratios and correspondingly high torque multiplication. They can also be utilized as acceleration reducers in low- to moderate-swiftness applications. And, because their decrease ratio is founded on the number of gear teeth by itself, they are more compact than other types of gears. Like fine-pitch business 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 use of dissimilar metals for the worm and gear also plays a part in quiet procedure.) This makes worm gears ideal 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 experienced in large equipment or crushing devices.
