  2. gears • A gear is a rotating machine part having teeth which combine with a complementary toothed part in order to cause leverage with motion. Two or more gears working together can produce a mechanical advantage through a greater gear ratio.

  3. Spur gear • Spur Gears are the most popular form and the most efficient type of gearing for the cost when transmitting power and uniform rotary motion from one parallel shaft to another. Within the limitations of center distance, spur gears provide a positive, constant speed drive, the speed of which may be increased or decreased by increasing or decreasing the number of teeth in the driving gear.

  4. Worm gear • Worm Gears are right angle drives providing large speed ratios on comparatively short center distances from 1/4” to 11”. When properly mounted and lubricated they function as the quietist and smoothest running type of gearing. Because of the high ratios possible with worm gearing, maximum speed reduction can be accomplished in less space than many other types of gearing.

  5. Crown gear • Crown gears are gears that have teeth project at right angles in their orientation the teeth are shaped like a crown and thus are called crown gears. A crown gear can only mesh accurately with another special gear, although crown gears are sometimes seen meshing with spur gears.
