Wormwheel gearboxes, or worm gearboxes, feature a gear arrangement in which a worm (i.e., a gear in the form of a screw) meshes with a worm gear (similar to a spur gear). Wormwheel gearboxes produce an output that is 90° from the input. A worm gearbox 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. Worm gearboxes are referred to as 90 degree gearboxes and worm gear reducers.
