Our complete type of worms and worm gears can be ordered through the EP Gear Guaranteed Same Day Shipment Plan for the fastest delivery possible.
Product Features
90°, non-intersecting shaft applications answer highly 
specialized power tranny needs.
Our worm gears provide smoothest, quietest type of gearing.
They offer high-ratio speed reduction in minimal spaces.
Their efficiency is easily increased by lowering ratios.
With some ratios, there is level of resistance to back driving.
Obtainable from 48 DP to 3 DP
Stocked as single, double and quad start configurations
Because the performance of a worm equipment drive depends on the lead angle and number of starts on the worm – and because increased efficiency is always a goal, the ratio ought to be kept only possible. To run correctly, worms and worm gears utilized 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 speed reduction in a limited space using correct angle (90°), non-intersecting shafts. When properly used, worms and worm gears supply 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 employed as velocity reducers in low- to medium-rate applications. And, because their decrease ratio is based on the amount of gear teeth only, they are smaller sized than other types of gears. Like fine-pitch lead screws, worm gears are usually self-locking, making them well suited for hoisting and lifting applications.
Although the sliding contact decreases efficiency, it provides extremely quiet operation. (The utilization of dissimilar metals for the worm and gear also plays a part in quiet procedure.) This causes worm gears suitable for use where noise should be minimized, such as in elevators. Furthermore, the use of a softer material for the gear means that it can absorb shock loads, like those skilled in large equipment or crushing machines.
