worm gear box assembly because the effectiveness of a worm gear drive depends on the business lead angle and quantity of starts on the worm – and because increased performance is always an objective, the ratio should be kept only possible. To run properly, worms and worm gears utilized 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 tranny applications requiring high-ratio quickness reduction in a restricted space using correct 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 capability to provide high reduction ratios and correspondingly high torque multiplication. They can also be utilized as speed reducers in low- to moderate-quickness applications. And, because their decrease ratio is founded on the number of gear teeth only, they are more compact than other types of gears. Like fine-pitch lead screws, worm gears are typically self-locking, which makes 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 gear also contributes to quiet operation.) This makes worm gears suitable for use where noise should be minimized, such as in elevators. In addition, the use of a softer material for the gear implies that it could absorb shock loads, like those skilled in heavy equipment or crushing devices.
