worm gear box assembly

Our complete line of worms and worm gears can be ordered through the EP Equipment Guaranteed Same Day time Shipment Plan for the quickest delivery possible.
Product Features
90°, non-intersecting shaft applications solution highly specialized power transmission needs.
Our worm gears offer the smoothest, quietest form of gearing.
They offer high-ratio speed reduction in minimal spaces.
Their efficiency is easily increased by lowering 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 performance of a worm gear drive depends on the business lead angle and number of starts on the worm – and because increased efficiency is always a goal, 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 swiftness reduction in a restricted space using correct angle (90°), nonintersecting shafts. When properly used, worms and worm gears supply the smoothest, quietest form 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-acceleration applications. And, because their decrease ratio is based on the amount of gear teeth alone, 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 decreases efficiency, it provides very quiet operation. (The utilization of dissimilar metals for the worm and equipment also plays a part in 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 means that it could absorb shock loads, like those skilled in large equipment or crushing machines.
