Our complete line of worms and worm gears could be ordered through the EP Gear Guaranteed Same Day time Shipment Program 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 decrease in minimal spaces.
Their efficiency is easily increased by decreasing ratios.
With some ratios, there is level of resistance to back driving.
Available from 48 DP to 3 DP
Stocked as single, dual and quad start configurations
Because the performance of a worm gear drive depends on the lead angle and quantity of starts on the worm – and because increased efficiency is always a goal, the ratio should be kept only 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 an effective answer for power tranny applications requiring high-ratio swiftness reduction in a restricted space using right angle (90°), non-intersecting shafts. When properly applied, worms and worm gears provide the smoothest, quietest form 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 speed reducers in low- to medium-swiftness applications. And, because their decrease ratio is based on the number of gear teeth by itself, they are more compact than other types of gears. Like fine-pitch lead screws, worm gears are typically self-locking, making them ideal 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 equipment also plays a part in quiet operation.) This produces worm gears suitable for use where noises should be minimized, such as in elevators. In addition, the use of a softer materials for the gear implies that it could absorb shock loads, like those experienced in weighty equipment or crushing devices.
