Product Features
90°, nonintersecting shaft applications solution highly specialized power tranny needs.
Our worm gears provide smoothest, quietest type of gearing.
They offer high-ratio speed decrease in minimal spaces.
Their efficiency is easily increased by lowering ratios.
With some ratios, there is level of resistance to back worm gear box assembly driving.
Available 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 quantity of starts on the worm – and because increased effectiveness is always a goal, the ratio ought to 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 a highly effective answer for power transmission applications requiring high-ratio speed reduction in a limited space using right angle (90°), non-intersecting shafts. When properly used, worms and worm gears provide 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 velocity reducers in low- to moderate-quickness applications. And, because their reduction ratio is founded on the amount of gear teeth only, they are smaller sized than other types of gears. Like fine-pitch business lead screws, worm gears are typically self-locking, which makes them ideal for hoisting and lifting applications.

Although the sliding contact decreases efficiency, it provides very quiet operation. (The utilization of dissimilar metals for the worm and equipment also contributes to quiet procedure.) This makes worm gears suitable for use where noise should be minimized, such as in elevators. In addition, the use of a softer materials for the gear implies that it can absorb shock loads, like those skilled in large equipment or crushing machines.
