WORM GEARS

Worm Gears are a Common Type of Gear

Worm GearsThe axes of worm gears shafts cross in space. The shafts of worm gears lie in parallel planes and may be skewed at any angle between zero and a right angle.

In worm gears, one gear has screw threads. Due to this, worm gears are quiet, vibration free and give a smooth output.

Worm gears and worm gear shafts are almost invariably at right angles.
