Our complete type of worms and worm gears can be ordered through the EP Gear Guaranteed Same Time Shipment System for the quickest delivery possible.
90°, nonintersecting shaft applications solution highly specialized power tranny needs.
Our worm gears provide smoothest, quietest form of gearing.
They provide high-ratio speed decrease in minimal spaces.
Their efficiency is easily increased by reducing 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 lead angle and quantity of begins on the worm – and because increased performance is always a goal, the ratio should be kept as low as possible. To run correctly, 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 transmitting applications requiring high-ratio acceleration reduction in a restricted space using correct angle (90°), nonintersecting shafts. When properly used, worms and worm gears provide the smoothest, quietest kind of gearing.
The primary benefit of worm gears is their ability to provide high reduction ratios and correspondingly high torque multiplication. They can also be applied as acceleration reducers in low- to moderate-acceleration applications. And, because their decrease ratio is based on the amount of gear teeth by itself, they are smaller sized than other styles of gears. Like fine-pitch lead screws, worm gears are usually self-locking, making them perfect for hoisting and lifting applications.
Although the sliding contact decreases efficiency, it provides very quiet operation. (The utilization of dissimilar metals for the worm and equipment also plays a part in quiet procedure.) This creates worm gears suitable for use where noises should be minimized, such as for example 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.
