Worm gears are used when large gear reductions are needed. It is common for worm gears to have reductions of 20:1, and even up to 300:1 or greater.

Many worm gears have an interesting property that no other gear set has: the worm can easily turn the gear, but the gear cannot turn the worm. This is because the angle on the worm is so shallow that when the gear tries to spin it, the friction between the gear and the worm holds the worm in place.

Our cast iron worm reducer is made in ribbed forged steel casings. Their surfaces are carburized and hardened to ensure parallelism of the axle and positioning accuracy. They can be perfectly combined to all kinds of frequency conversion, braking and servo motors. A great variety of worm reducers with different designs are available with us!
