Our complete line of worms and worm gears can be ordered through the EP Equipment Guaranteed Same Time worm gear box assembly Shipment Program for the quickest delivery possible.
Product Features
90°, nonintersecting shaft applications answer highly specialized power tranny 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 reducing 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 efficiency of a worm equipment drive depends upon the business lead angle and amount of begins on the worm – and because increased effectiveness is always a goal, the ratio ought to be kept as low as possible. To run correctly, worms and worm gears used 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 acceleration reduction in a restricted space using correct angle (90°), nonintersecting shafts. When properly used, worms and worm gears provide the smoothest, quietest type 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 used as quickness reducers in low- to medium-rate applications. And, because their decrease ratio is based on the number of gear teeth only, they are smaller sized than other types of gears. Like fine-pitch business lead screws, worm gears are usually self-locking, which makes them perfect for hoisting and lifting applications.
