Our complete line of worms and worm gears can be ordered through the EP Gear Guaranteed Same Day Shipment Plan for the fastest delivery possible.
90°, non-intersecting shaft applications solution highly specialized power transmission needs.
Our worm gears provide smoothest, quietest type of gearing.
They offer high-ratio speed decrease in minimal spaces.
Their efficiency is easily increased by lowering ratios.
With some ratios, there is resistance to back driving.
Obtainable from 48 DP to 3 DP
Stocked as single, dual and quad start configurations
Because the efficiency of a worm gear drive depends on the business lead angle and quantity of begins 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 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 tranny applications requiring high-ratio velocity reduction in a restricted space using right angle (90°), non-intersecting shafts. When properly used, worms and worm gears provide the smoothest, quietest type 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 utilized as velocity reducers in low- to moderate-rate applications. And, because their reduction ratio is founded on the amount of gear teeth only, they are more compact than other types of gears. Like fine-pitch business lead screws, worm gears are typically self-locking, making them ideal 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 gear also plays a part in quiet operation.) This creates worm gears ideal for use where sound should be minimized, such as in elevators. In addition, the use of a softer material for the gear implies that it could absorb shock loads, like those experienced in heavy equipment or crushing devices.
