worm gear box assembly

Our complete line of worms and worm gears could be ordered through the EP Equipment Guaranteed Same Time Shipment System for the quickest delivery possible.
Product Features
90°, worm gear box assembly nonintersecting shaft applications solution highly specialized power transmission needs.
Our worm gears offer the smoothest, quietest kind of gearing.
They provide high-ratio speed decrease in minimal spaces.
Their efficiency is easily increased by decreasing ratios.
With some ratios, there is resistance to back driving.
Offered 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 lead angle and number of starts on the worm – and because increased efficiency is always an objective, the ratio should be kept as low as 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 an effective answer for power tranny applications requiring high-ratio velocity reduction in a limited space using correct angle (90°), nonintersecting shafts. When properly applied, 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 can also be used as quickness reducers in low- to medium-speed applications. And, because their reduction ratio is based on the amount of gear teeth by itself, they are smaller sized than other types of gears. Like fine-pitch business lead screws, worm gears are usually self-locking, making them ideal for hoisting and lifting applications.

Although the sliding contact decreases efficiency, it provides extremely quiet operation. (The utilization of dissimilar metals for the worm and equipment also plays a part in quiet procedure.) This makes worm gears suitable for use where sound should be minimized, such as for example in elevators. Furthermore, the usage of a softer material for the gear means that it could absorb shock loads, like those experienced in weighty equipment or crushing machines.
