Description
Worm drives are a compact means of substantially decreasing speed and increasing torque. Small electric motors are generally high-speed and low-torque; the addition of a worm drive increases the range of applications it may be suitable for, especially when the worm drive’s compactness is considered.

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 (similar to a spur gear). The two elements are also called the worm screw (or worm gear shaft) and worm wheel. The terminology is often confused by the imprecise use of the worm gear to refer to the worm, the worm gear, or the worm drive as a unit.
One of the significant advantages of worm gear drive units is that they can transfer motion at 90 degrees.
Worm gears are used on many lift/elevator and escalator-drive applications due to their compact size and the non-reversibility of the gear. Worm drives are used in presses, rolling mills, conveying engineering, mining industry machines, rudders, and worm drive saws. In addition, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
Worm gears are usually used when significant speed reductions are needed. The reduction ratio is determined by the number of starts of the worm and the number of teeth on the worm gear. But worm gears have quiet sliding contact but tend to produce heat and have relatively low transmission efficiency.
