Our complete type of worms and worm gears could be ordered through the EP Equipment Guaranteed Same Time Shipment Plan for the quickest 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 provide high-ratio speed reduction in minimal spaces.
Their efficiency is easily increased by reducing ratios.
With some ratios, there is level of 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 upon the lead angle and number of starts on the worm – and because increased effectiveness is always an objective, 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 transmitting applications requiring high-ratio acceleration reduction in a restricted space using right 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 capability to provide high reduction ratios and correspondingly high torque multiplication. They may also be applied as acceleration reducers in low- to medium-velocity applications. And, because their decrease ratio is based on the number of gear teeth by itself, 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 very quiet operation. (The utilization of dissimilar metals for the worm and gear also plays a part in quiet operation.) This produces worm gears ideal for use where noise should be minimized, such as in elevators. Furthermore, the usage of a softer material for the gear implies that it could absorb shock loads, like those experienced in weighty equipment or crushing machines.
