Our complete line of worms and worm gears could be ordered through the EP Equipment Guaranteed Same Day Shipment System for the 
quickest delivery possible.
Product Features
90°, non-intersecting shaft applications solution highly specialized power transmission needs.
Our worm gears provide smoothest, quietest kind of gearing.
They provide high-ratio speed reduction 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, double and quad start configurations
Because the performance of a worm gear drive depends upon the business lead angle and amount of starts on the worm – and because increased performance is always an objective, the ratio ought to be kept only possible. To run properly, 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 right angle (90°), nonintersecting shafts. When properly used, worms and worm gears supply 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 may also be used as speed reducers in low- to medium-rate applications. And, because their reduction ratio is based on the amount of gear teeth alone, they are smaller sized than other styles of gears. Like fine-pitch lead screws, worm gears are typically self-locking, making them ideal for hoisting and lifting applications.
Although the sliding contact reduces efficiency, it provides extremely quiet operation. (The usage of dissimilar metals for the worm and gear also contributes to quiet operation.) This causes worm gears ideal for use where noises should be minimized, such as for example in elevators. Furthermore, the utilization of a softer material for the gear means that it can absorb shock loads, like those skilled in heavy equipment or crushing devices.
