A worm gearbox, or also known as a worm drive gearbox, consists of a worm wheel and a worm that is perpendicular to the wheel. An electric motor produces power to rotate the worm, which in turn drives the worm wheel. The worm gearbox is one of the most common gearboxes in the market. It has high reduction ratio, low noise levels and relatively low maintenance. When space is an issue, small worm gearboxes prove as a perfect solution. Another significant advantage is that it prevents back driving, which allow users to stop their machine very quickly. Shafttech is the official distributor for SITI (Italy) worm gearboxes.
