Worm gears (or wormwheel gears) and worms (or 
worm drives) are designed to work together to transfer motion between nonintersecting shaft at correct Enveloping Worm Gear angles. Worm gears and worms, which resemble spur gears and screws, respectively, combine to provide a high reduction ratio in a compact gear system. Our floor worm gears and surface worms are manufactured for exceptionally smooth and quite operation.
