Our complete line of worms and worm gears could be ordered through the EP Equipment Guaranteed Same Time Shipment Program for the fastest delivery possible.
Product Features
90°, non-intersecting shaft applications answer highly specialized power tranny needs.
Our worm gears offer the 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 resistance to back driving.
Obtainable from 48 DP to 3 DP
Stocked as single, dual and quad start configurations

Because the effectiveness of a worm gear drive depends on the lead angle and amount of begins on the worm – and because increased effectiveness is always a goal, the ratio ought to 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 provide a highly effective answer for power transmission applications requiring high-ratio acceleration reduction in a restricted space using correct angle (90°), nonintersecting shafts. When properly applied, worms and worm gears provide the smoothest, quietest type of gearing.

The primary benefit of worm gears is their ability to provide high reduction worm gear box assembly ratios and correspondingly high torque multiplication. They may also be used as rate reducers in low- to medium-acceleration applications. And, because their decrease ratio is based on the amount of gear teeth by itself, they are smaller sized 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 decreases efficiency, it provides extremely quiet operation. (The usage of dissimilar metals for the worm and gear also contributes to quiet procedure.) This makes worm gears suitable for use where noise 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 heavy equipment or crushing devices.
