Our complete type of worms and worm gears could be ordered through the EP Equipment Guaranteed Same Time Shipment Program for the fastest delivery possible.
90°, nonintersecting shaft applications solution highly specialized power transmitting 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 decreasing ratios.
With some ratios, there is resistance to back driving.
Offered from 48 DP to 3 DP
Stocked as single, dual and quad start configurations
Because the performance of a worm equipment drive depends on the lead angle and amount of starts on the worm – and because increased performance is always a goal, the ratio should be kept as low as 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 swiftness reduction in a limited space using right angle (90°), non-intersecting 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 worm gear box assembly torque multiplication. They can also be used as acceleration reducers in low- to medium-acceleration applications. And, because their reduction ratio is founded on the amount of gear teeth only, they are smaller sized than other types of gears. Like fine-pitch lead screws, worm gears are usually self-locking, making them well suited for hoisting and lifting applications.
Although the sliding contact decreases efficiency, it provides extremely 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 noise should be minimized, such as in elevators. Furthermore, the use of a softer material for the gear implies that it could absorb shock loads, like those experienced in weighty equipment or crushing devices.
