worm gear box assembly Because the effectiveness of a worm gear drive depends upon the business lead angle and number of begins on the worm – and because increased efficiency is always a goal, the ratio should be kept as low as possible. To run correctly, worms and worm gears utilized 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 transmitting applications requiring high-ratio rate reduction in a limited 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 utilized as rate reducers in low- to moderate-acceleration applications. And, because their reduction ratio is based on the number of gear teeth alone, they are more compact than other types of gears. Like fine-pitch business lead screws, worm gears are usually self-locking, making them perfect for hoisting and lifting applications.

Although the sliding contact reduces efficiency, it provides very quiet operation. (The usage of dissimilar metals for the worm and gear also contributes to quiet procedure.) This makes worm gears suitable for use where sound should be minimized, such as in elevators. Furthermore, the use of a softer materials for the gear implies that it can absorb shock loads, like those skilled in large equipment or crushing machines.
