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