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
  • Economical
