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.
90°, nonintersecting shaft applications solution highly specialized power tranny needs.
Our worm gears offer the smoothest, quietest type of gearing.
They provide high-ratio speed reduction in minimal spaces.
Their efficiency is easily increased by decreasing ratios.
With some ratios, there is level of resistance to back driving.
Offered 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 business lead angle and amount 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 must have the same diametral pitch and threads.
Worms & Worm Gears
EP Gear’s worms and worm gears provide an effective answer for power tranny applications requiring high-ratio rate reduction in a restricted space using right angle (90°), nonintersecting shafts. When properly applied, worms and worm gears supply the smoothest, quietest form of gearing.
The primary advantage of worm gears is their capability to provide high reduction ratios and correspondingly high torque multiplication. They can also be employed as rate reducers in low- to moderate-velocity applications. And, because their reduction ratio is based on the number of gear teeth only, they are smaller sized than other types of gears. Like fine-pitch lead screws, worm gears are typically self-locking, making them perfect 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 gear also plays a part in quiet procedure.) This would make worm gears ideal for use where sound should be minimized, such as for example in elevators. In addition, the use of a softer materials for the gear implies that it can absorb shock loads, like those experienced in weighty equipment or crushing devices.
