Our complete type of worms and worm gears can be ordered through the EP Equipment Guaranteed Same Day Shipment Program for the quickest delivery possible.
worm gear box assembly Product Features
90°, nonintersecting shaft applications solution highly specialized power transmission needs.
Our worm gears offer the smoothest, quietest form of gearing.
They provide high-ratio speed reduction in minimal spaces.
Their efficiency is easily increased by reducing ratios.
With some ratios, there is level of resistance to back driving.
Offered from 48 DP to 3 DP
Stocked as single, double and quad start configurations
Because the efficiency of a worm equipment drive depends on the business lead angle and number of begins on the worm – and because increased efficiency 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 quickness reduction in a limited space using correct angle (90°), nonintersecting shafts. When properly applied, worms and worm gears supply the smoothest, quietest kind 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 quickness reducers in low- to moderate-speed applications. And, because their decrease ratio is based on the amount of gear teeth alone, they are smaller sized than other styles of gears. Like fine-pitch lead screws, worm gears are typically self-locking, which makes them well suited for hoisting and lifting applications.
Although the sliding contact reduces efficiency, it provides extremely quiet operation. (The use of dissimilar metals for the worm and gear also plays a part in quiet operation.) This makes worm gears suitable for use where noise should be minimized, such as for example in elevators. Furthermore, the utilization of a softer materials for the gear implies that it can absorb shock loads, like those skilled in heavy equipment or crushing devices.
