Our complete type of worms and worm gears could be ordered through the EP Equipment Guaranteed Same Day Shipment Program for the fastest delivery possible.
90°, non-intersecting shaft applications answer highly specialized power transmission needs.
Our worm gears provide smoothest, quietest form of gearing.
They offer high-ratio speed decrease in minimal spaces.
Their efficiency is easily increased by reducing 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 performance of a worm equipment drive depends upon the business lead angle and quantity of begins on the worm – and because increased performance is always a goal, the ratio ought to be kept as low as possible. To run properly, 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 a highly effective answer for power transmission applications requiring high-ratio quickness reduction in a restricted space using right angle (90°), nonintersecting shafts. When worm gear box assembly properly used, worms and worm gears provide the smoothest, quietest form of gearing.
The primary advantage of worm gears is their ability to provide high reduction ratios and correspondingly high torque multiplication. They can also be used as swiftness reducers in low- to medium-rate 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 business 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 use of dissimilar metals for the worm and equipment also plays a part in quiet operation.) This makes worm gears ideal for use where sound should be minimized, such as 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 devices.
