This Demonstration shows a cycloidal speed reducer, which consists of a stator (blue) housing three rotating parts: the input shaft with its eccentric cam (green), the cycloidal rotor (gray), and the output disc (red). The output disc has a number of pins (red) that fit inside the drive holes (yellow) in the rotor.[more]
Substantial speed reductions can be achieved without the use of gears. The reduction obtained is equal to , where is the inside radius of the stator and is the radius of the rotor.[less]
