Our complete type of worms and worm gears can be ordered through the EP Equipment Guaranteed Same Day Shipment Plan for the quickest delivery possible.
90°, nonintersecting shaft applications answer highly specialized power tranny needs.
Our worm gears provide smoothest, quietest kind of gearing.
They offer high-ratio speed reduction in minimal spaces.
Their efficiency is easily increased by decreasing ratios.
With some ratios, there is resistance to back driving.
Obtainable 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 quantity of begins on the worm – and because increased effectiveness is always an objective, the ratio ought to 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 rate reduction in a restricted space using right angle (90°), nonintersecting shafts. When properly applied, worms and worm gears supply the smoothest, quietest type 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 moderate-quickness applications. And, because their reduction ratio is founded on the number of gear teeth only, they are more compact than other styles of gears. Like fine-pitch worm gear box assembly business lead screws, worm gears are usually self-locking, which makes them perfect for hoisting and lifting applications.
Although the sliding contact decreases efficiency, it provides very quiet operation. (The usage of dissimilar metals for the worm and equipment also plays a part in quiet operation.) This makes worm gears ideal for use where sound should be minimized, such as for example in elevators. In addition, 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.
