Our complete type of worms and worm gears could be ordered through the EP Equipment Guaranteed Same Day Shipment Program for the fastest delivery possible.
Product Features
90°, nonintersecting shaft applications answer highly specialized power transmission needs.
Our worm gears offer the smoothest, quietest type of gearing.
They offer high-ratio speed reduction in minimal spaces.
Their efficiency is easily increased by reducing ratios.
With some ratios, there is resistance to back driving.
Available from 48 DP to 3 DP
Stocked as single, dual and quad start configurations
Because the efficiency of a worm gear drive depends upon the business lead angle and quantity of begins 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 worm gear box assembly 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 tranny applications requiring high-ratio swiftness reduction in a limited space using correct angle (90°), nonintersecting shafts. When properly applied, worms and worm gears provide 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 utilized as quickness reducers in low- to moderate-rate applications. And, because their decrease ratio is founded on the amount of gear teeth only, they are more compact than other types of gears. Like fine-pitch lead screws, worm gears are usually self-locking, which makes them ideal for hoisting and lifting applications.
Although the sliding contact decreases efficiency, it provides very quiet operation. (The usage of dissimilar metals for the worm and equipment also plays a part in quiet procedure.) This makes worm gears ideal for use where sound should be minimized, such as in elevators. In addition, the use of a softer materials for the gear means that it can 
absorb shock loads, like those skilled in large equipment or crushing machines.
