Our worm gears provide smoothest, quietest type of gearing.
They offer high-ratio speed decrease in minimal spaces.
Their efficiency is easily increased by reducing ratios.
With some ratios, there is level of resistance to back driving.
Offered from 48 DP to 3 DP
Stocked as single, double and quad start configurations

Because the performance of a worm equipment drive depends on the lead angle and number of starts on the worm – and because increased effectiveness is always an objective, the ratio ought to be kept as low as possible. To run properly, worms and worm gears used worm gear box assembly 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 transmission applications requiring high-ratio swiftness reduction in a limited space using correct angle (90°), non-intersecting shafts. When properly used, worms and worm gears provide the smoothest, quietest type of gearing.

The primary advantage of worm gears is their ability to provide high reduction ratios and correspondingly high torque multiplication. They may also be used as speed reducers in low- to moderate-swiftness applications. And, because their decrease 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, making them perfect for hoisting and lifting applications.

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