Our complete type of worms and worm gears can be ordered through the EP Gear Guaranteed Same Day Shipment System for the fastest delivery worm gear box assembly possible.
90°, non-intersecting shaft applications answer highly specialized power tranny needs.
Our worm gears offer the smoothest, quietest form of gearing.
They offer 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.
Offered from 48 DP to 3 DP
Stocked as single, double and quad start configurations
Because the efficiency of a worm gear drive depends upon the business lead angle and number of starts on the worm – and because increased efficiency is always an objective, the ratio ought to be kept only possible. To run correctly, 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 an effective answer for power transmitting applications requiring high-ratio velocity reduction in a limited space using right angle (90°), nonintersecting shafts. When properly used, worms and worm gears provide the smoothest, quietest type 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 speed reducers in low- to moderate-rate applications. And, because their reduction ratio is founded on the number of gear teeth alone, they are more compact than other types of gears. Like fine-pitch lead screws, worm gears are typically self-locking, which makes them perfect for hoisting and lifting applications.
