Our complete line of worms and worm gears could be ordered through the EP Gear Guaranteed Same Day time Shipment Plan for the quickest delivery possible.
90°, nonintersecting shaft applications solution highly specialized power transmitting needs.
Our worm gears provide smoothest, quietest form of gearing.
They offer high-ratio speed reduction 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 effectiveness of a worm gear drive depends on the business lead angle and amount of starts on the worm – and because increased effectiveness 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 an effective answer for power transmitting applications requiring high-ratio acceleration reduction in a restricted space using right angle (90°), non-intersecting shafts. When 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 may also be used as speed reducers in low- to moderate-rate applications. And, because their reduction ratio is founded on the number of gear teeth only, they are smaller sized than other styles of gears. Like fine-pitch lead screws, worm gears are usually self-locking, which makes 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 contributes to quiet procedure.) This makes worm gears ideal for use where noise should be minimized, such as for example in elevators. In addition, the use of a softer material for the gear means that it could absorb shock loads, like those experienced in large equipment or crushing machines.
