Our complete type of worms and worm gears can be ordered through the EP Equipment Guaranteed Same Day time Shipment Program for the quickest delivery possible.
90°, non-intersecting shaft applications solution highly specialized power transmitting needs.
Our worm gears offer the smoothest, quietest kind of gearing.
They provide high-ratio speed reduction 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, double and quad start configurations
Because the effectiveness of a worm gear drive depends upon the lead angle and amount of starts on the worm – and because increased performance is always an objective, the ratio ought to be kept only possible. To run properly, 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 a highly effective answer for power transmission applications requiring high-ratio acceleration reduction in a restricted space using correct angle (90°), nonintersecting shafts. When properly applied, worms and worm gears provide 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 used as rate 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, making them well suited for hoisting and lifting applications.
Although the sliding contact decreases efficiency, it provides very quiet operation. (The usage of dissimilar worm gear box assembly metals for the worm and equipment also contributes to quiet operation.) This makes worm gears suitable for use where sound 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 devices.
