Our complete type of worms and worm gears could be ordered through the EP Gear Guaranteed Same Day Shipment System for the quickest delivery possible.
Product Features
90°, non-intersecting shaft applications answer highly specialized power transmission needs.
Our worm gears offer the smoothest, quietest kind of gearing.
They provide high-ratio speed reduction in minimal spaces.
Their efficiency is easily increased by lowering ratios.
With some ratios, there is resistance to back driving.
Offered from 48 DP to 3 DP
Stocked as single, dual and quad start configurations

Because the effectiveness of a worm gear drive depends upon the business lead angle and quantity of begins on the worm – and because increased worm gear box assembly performance is always an objective, the ratio ought to be kept only 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 velocity reduction in a limited space using correct angle (90°), nonintersecting shafts. When properly used, worms and worm gears supply the smoothest, quietest kind 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 medium-acceleration applications. And, because their reduction ratio is based on the number of gear teeth only, they are more compact than other styles of gears. Like fine-pitch lead screws, worm gears are usually self-locking, making them perfect for hoisting and lifting applications.

Although the sliding contact reduces efficiency, it provides extremely quiet operation. (The utilization of dissimilar metals for the worm and equipment also contributes to quiet procedure.) This makes worm gears ideal for use where sound 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 devices.
