Our complete type of worms and worm gears could be ordered through the EP Equipment Guaranteed Same Day Shipment Program for the quickest delivery possible.
90°, nonintersecting shaft applications solution highly specialized power tranny needs.
Our worm gears offer the smoothest, quietest type of gearing.
They offer high-ratio speed reduction in minimal spaces.
Their efficiency is easily increased by decreasing ratios.
With some ratios, there is level of resistance to back driving.
Available from 48 DP to 3 DP
Stocked as single, dual and quad start configurations
Because the efficiency of a worm gear drive depends on the lead angle and quantity of starts on the worm – and because increased effectiveness is always a goal, the ratio should be kept only possible. To run correctly, worms and worm gears used 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°), non-intersecting shafts. When properly used, worms and worm gears provide the smoothest, quietest kind of gearing.
The primary advantage of worm gears is their capability to provide high reduction ratios and correspondingly high torque multiplication. They can also be used as acceleration reducers in low- to moderate-velocity applications. And, because their reduction ratio is based on the number of gear teeth alone, they are more compact than other styles of gears. Like fine-pitch business 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 equipment also plays a part in quiet operation.) This makes worm gears suitable for use where noise should be minimized, such as in elevators. In addition, the utilization of a softer material for the gear means that it could absorb shock loads, like those skilled in weighty equipment or crushing devices.
