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

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

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

The main advantage of cycloidal reducers is their property of zero or near-zero backlash, which results in high precision and high accuracy. That is especially popular where highly specific and accurate positioning is necessary, for example in robotic applications, machine equipment, and comparable applications. Cycloidal reducers also feature rolling as opposed to sliding contact, therefore experiencing less overall put on.
