When you want to transmit rotary motion between intersecting shafts, bevel gear set is one choice. Most bevel gears are mounted at 90° to each other, but it is not a rule. In fact, bevel gears can be manufactured for nearly any angle. We create some bevel gear examples here to show you the motion.
The number of teeth on the mating gears can be different. There is a special kind of bevel gears-miter gears. Miter gears are gears that have the same number of teeth with 90° shafts, and the ratio is 1:1. Usually miter gears are used to simply change the motion direction. There are some miter gears in the samples.
