worm gear box assembly

Our complete line of worms and worm gears could be ordered worm gear box assembly through the EP Gear Guaranteed Same Day Shipment Program for the fastest delivery possible.
Product Features
90°, nonintersecting shaft applications solution highly specialized power transmission 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 resistance to back driving.
Offered from 48 DP to 3 DP
Stocked as single, double and quad start configurations

Because the effectiveness of a worm equipment drive depends on the lead angle and amount of begins on the worm – and because increased efficiency is always an objective, the ratio should 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 a highly effective answer for power transmitting applications requiring high-ratio swiftness reduction in a restricted space using correct angle (90°), nonintersecting shafts. When properly applied, worms and worm gears supply the smoothest, quietest form 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 used as rate reducers in low- to medium-acceleration applications. And, because their reduction ratio is founded on the number of gear teeth by itself, they are smaller sized than other styles of gears. Like fine-pitch business lead screws, worm gears are typically self-locking, making them well suited 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 equipment also contributes to quiet operation.) This makes worm gears ideal for use where noise should be minimized, such as for example in elevators. Furthermore, the use of a softer materials for the gear implies that it can absorb shock loads, like those skilled in heavy equipment or crushing machines.
