Molded Glass Filled Housing Speed Reducers
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, wormwheel speed reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement in which a gear in the form of a screw, also known as a worm, meshes with a worm gear. These gears are typically made from bronze and the worms are steel or stainless steel.
While a worm gear is similar to a spur gear, worm gearboxes are significantly smaller than other gear reduction boxes. A primary benefit of worm gear reducers is that they produce an output that is 90° from the input and can be used to transmit higher torque or reduce rotational speed. Most often, a worm gearbox has right hand threads; to change the direction of the output, a left-hand thread worm gearbox is required.
Additional benefits of worm drive gearboxes include:
- High reduction ratios
- High torque multiplication
- Quiet operation
- Absorbs shock loads
