A cycloidal reducer is a type of gear reducer. The basic operation is an insight shaft connects to and drives an eccentric bearing. This gear box for greenhouse bearing further drives a cycloidal disk (sometimes referred to as a cam) that connects to an output shaft.

Regular cycloidal speed reducers, such as these Dojen series reducers from Onvio, provide zero backlash by combining a compound reduction cam with preloaded, complete compliment needle bearing cam followers.

The cycloidal disk (or cam) has lobes or teeth that build relationships some type of cam follower, typically a pin or needle bearings. The eccentric rotation of the cam is definitely transformed into rotation of an result shaft at a lower life expectancy speed and a rise in torque.

The main benefit of cycloidal reducers is their house of zero or near-zero backlash, which results in high precision and high accuracy. This is especially popular where highly precise and accurate positioning is necessary, for instance in robotic applications, machine equipment, and comparable applications. Cycloidal reducers also feature rolling instead of sliding contact, therefore experiencing less overall wear.
