Our complete type of worms and worm gears could be ordered through the EP Gear Guaranteed Same Day time Shipment System 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 decrease in minimal spaces.
Their efficiency is easily increased by reducing ratios.
With some ratios, there is resistance to back driving.
Available 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 begins on the worm – and because increased performance is always an objective, the ratio ought to 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 an effective answer for power tranny applications requiring high-ratio speed 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 capability to provide high reduction ratios and correspondingly high torque multiplication. They may also be utilized as quickness reducers in low- to medium-acceleration applications. And, because their decrease ratio is founded on the amount of gear teeth only, they are smaller sized than other types of gears. Like fine-pitch business lead screws, worm gears are usually self-locking, making them ideal for hoisting and lifting applications.
Although the sliding contact reduces efficiency, it provides extremely quiet operation. (The utilization of dissimilar metals for the worm and gear also contributes to quiet procedure.) This would make worm gears ideal for use where noises 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 experienced in large equipment or crushing machines.
There is fantastic worth in taking time to comprehend the subject of worm gear box assembly, however the Web might or could not be your ideal source of info.
