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 offer the 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 upon the lead angle and quantity of starts on the worm – and because increased effectiveness is always an objective, the ratio ought to be kept 
only possible. To run properly, worms and worm gears used together must have the same diametral pitch and threads.
Worms & Worm Gears
EP Gear’s worms and worm gears provide a highly effective answer for power transmission applications requiring high-ratio speed reduction in a limited space using correct angle (90°), nonintersecting shafts. When properly applied, worms and worm gears provide the smoothest, quietest kind 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 applied as speed reducers in low- to moderate-speed applications. And, because their decrease ratio is founded 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 typically self-locking, which makes them perfect for hoisting and lifting applications.
Although the sliding contact reduces efficiency, it provides extremely quiet operation. (The use of dissimilar metals for the worm and equipment also plays a part in quiet operation.) This produces worm gears suitable for use where noises should be minimized, such as in elevators. In addition, the use of a softer material for the gear means that it can absorb shock loads, like those experienced in large equipment or crushing machines.
