Our complete line of worms and worm gears can be ordered through the EP Gear Guaranteed Same Day Shipment Program for the quickest delivery possible.
90°, non-intersecting shaft applications answer highly specialized power transmission needs.
Our worm gears offer the smoothest, quietest type of gearing.
They worm gear box assembly provide high-ratio speed decrease in minimal spaces.
Their efficiency is easily increased by lowering ratios.
With some ratios, there is level of resistance to back driving.
Obtainable 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 effectiveness is always an objective, the ratio should be kept as low as possible. To run properly, worms and worm gears utilized together will need to have the same diametral pitch and threads.
Worms & Worm Gears
EP Gear’s worms and worm gears provide a highly effective answer for power transmitting applications requiring high-ratio speed reduction in a restricted space using correct angle (90°), nonintersecting shafts. When properly applied, worms and worm gears supply the smoothest, quietest form of gearing.
The primary advantage of worm gears is their capability to provide high reduction ratios and correspondingly high torque multiplication. They can also be used as velocity reducers in low- to moderate-swiftness applications. And, because their decrease ratio is founded on the amount of gear teeth only, they are more compact than other styles of gears. Like fine-pitch lead screws, worm gears are usually self-locking, which makes them well suited for hoisting and lifting applications.
