Worm Gearbox

Widi is a worm gearboxs manufacturer and supplier. A worm gearbox reducer is a gear arrangement. Worm gearboxes are used to take a rated motor speed and produce a low-speed, high torque output based on the reduction ratio, offering users a number of advantages. You also can call it worm gear reducer.

Worm gears are made up of a worm and a gear (also known as a worm wheel), which have non-parallel, non-intersecting shafts that are aligned 90 degrees to each other. The worm resembles a screw with a V-type thread, while the gear resembles a spur gear. Typically, the worm is the driving component, with the worm's thread advancing the gear's teeth.

Types of Worm Gearbox

  • Single Stage Reduction Worm Gearbox
  • Double Stage Reduction Worm Gearbox
