  • What is worm wheel enveloping?
  • Because the worm sees comparatively more wear than the wheel, often dissimilar materials are used for each, such as a hardened steel worm driving a bronze wheel. Plastic worm wheels are also available. Enveloping refers to the way in which the worm wheel teeth wrap partially around the worm or the worm teeth wrap partially around the wheel.
  • What is a worm wheel used for?
  • The resistance to back-driving through the worm wheel can be used to prevent belt reversal when the conveyor stops. Other common applications are in valve actuators, jacks, and circular saws. They are sometimes used for indexing or as precision drives for telescopes and other instruments.
  • Do Worm drives need special lubricants?
  • Also, special lubricants are recommended for worm drives because of the high pressures between teeth as well as the possibility of galling between the dissimilar worm and wheel materials. Housings for worm drives are often fitted with cooling fins to dissipate heat from the oil.
  • What is a worm drive?
  • A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm gear (which is similar in appearance to a spur gear, and is also called a worm wheel). Like other gear arrangements, a worm drive can reduce rotational speed or allow higher torque to be transmitted.
