Our complete line of worms and worm gears can be ordered through the EP Equipment Guaranteed Same Time Shipment System for the quickest delivery possible.
Product Features
90°, non-intersecting shaft applications answer highly specialized power transmitting 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 decreasing ratios.
With some ratios, there is resistance to back driving.
Available from 48 DP to 3 DP
Stocked as single, double and quad start configurations
Because the efficiency of a worm gear drive depends upon the business lead angle and number of starts on the worm – and because increased efficiency is always an objective, the ratio ought to be kept as low as possible. To run properly, worms and worm gears utilized together must have the same diametral pitch and threads.
Worms & Worm Gears
EP Gear’s worms and worm gears provide a highly effective answer for power transmission applications requiring high-ratio quickness reduction in a restricted space using right angle (90°), non-intersecting shafts. When properly used, 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 employed as rate reducers in low- to medium-velocity applications. And, because their reduction ratio is based on the number of gear teeth by itself, they are more compact than other styles of gears. Like fine-pitch business lead screws, worm gears are usually self-locking, making them ideal for hoisting and lifting applications.
Although the sliding contact decreases efficiency, it provides extremely quiet operation. (The use of dissimilar 
metals for the worm and gear also plays a part in quiet procedure.) This will make worm gears ideal for use where noise should be minimized, such as in elevators. Furthermore, the use of a softer materials for the gear means that it could absorb shock loads, like those skilled in heavy equipment or crushing devices.
