Our complete line of worms and worm gears can be ordered through the EP Equipment Guaranteed Same Time Shipment System for the fastest delivery possible.
Product Features
90°, non-intersecting shaft applications solution highly specialized power transmitting needs.
Our worm gears provide smoothest, quietest kind of gearing.
They offer high-ratio speed decrease in minimal spaces.
Their efficiency is easily increased by reducing 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 effectiveness of a worm gear drive depends on the lead angle and number of begins on the worm – and because increased efficiency is always a goal, the ratio should be kept only possible. To run correctly, 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 rate worm gear box assembly reduction in a limited space using correct angle (90°), non-intersecting shafts. When properly applied, worms and worm gears provide the smoothest, quietest type of gearing.
The primary benefit of worm gears is their capability to provide high reduction ratios and correspondingly high torque multiplication. They may also be used as speed reducers in low- to medium-swiftness applications. And, because their decrease ratio is based on the number 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, making them well suited 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 operation.) This makes worm gears ideal for use where noise should be 
minimized, such as for example in elevators. Furthermore, the use of a softer materials for the gear means that it can absorb shock loads, like those experienced in heavy equipment or crushing machines.
