Product Features
90°, non-intersecting shaft applications solution highly specialized power tranny 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.

Because the performance of a worm equipment drive depends on the lead angle and quantity of begins on the worm – and because increased efficiency is always an objective, 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 an effective answer for power transmission applications requiring high-ratio speed reduction in a limited space using correct angle (90°), nonintersecting shafts. When properly applied, worms and worm gears provide the smoothest, quietest form of gearing.

The primary advantage of worm gears is their ability to provide high reduction ratios and correspondingly high torque multiplication. They can also be employed as acceleration reducers in low- to moderate-rate applications. And, because their decrease ratio is founded on the number of gear teeth only, they are more compact than other types of gears. Like fine-pitch lead screws, worm gears are typically self-locking, which makes them perfect for hoisting and lifting applications.

Although the sliding contact reduces efficiency, it provides very quiet operation. (The utilization of dissimilar metals for the worm and gear also contributes to quiet operation.) This makes worm gears ideal for use where noises should be minimized, such as for example in elevators. In addition, the use of a softer material for the gear implies that it can absorb shock loads, like those experienced in heavy equipment or crushing machines.
