Our complete type 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°, nonintersecting shaft applications solution highly specialized power transmission needs.
Our worm gears provide smoothest, quietest type of gearing.
They offer high-ratio speed decrease in minimal spaces.
Their efficiency is easily increased by lowering ratios.
With some ratios, there is level of resistance to back driving.
Available 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 performance is always a goal, 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 quickness reduction in a limited space using correct angle (90°), non-intersecting shafts. When properly applied, worms and worm gears supply 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 used as rate reducers in low- to medium-rate applications. And, because their decrease ratio is based on the number of gear teeth alone, they are more compact than other styles of gears. Like fine-pitch business lead screws, worm gears are typically self-locking, which makes them ideal for hoisting and lifting applications.

Although the sliding contact reduces efficiency, it provides very quiet operation. (The usage of dissimilar metals for the worm and gear also plays a part in quiet operation.) This would make worm gears ideal for use where sound should be minimized, such as for example in elevators. Furthermore, the use of a softer materials for the gear means that it could absorb shock loads, like those experienced in heavy equipment or crushing devices.
