Worm gears (or wormwheel gears) and worms (or worm drives) are created to interact to transfer motion between nonintersecting shaft at right angles. Worm gears and worms, which resemble spur gears and screws, respectively, combine to supply a high decrease ratio in a compact gear Enveloping Worm Gear system. Our floor worm gears and surface worms are engineered for remarkably smooth and quite operation.
