What is a cycloidal reducer?

A cycloidal reducer is a kind of gear reducer. The essential operation is an insight shaft connects to and Bearing drives an eccentric bearing. This bearing further drives a cycloidal disk (sometimes referred to as a cam) that connects to an result shaft.

Common cycloidal speed reducers, such as for example these Dojen series reducers from Onvio, offer zero backlash by combining a substance reduction cam with preloaded, complete compliment needle bearing cam followers.

The cycloidal disk (or cam) has lobes or teeth that engage with some form of cam follower, typically a pin or needle bearings. The eccentric rotation of the cam is certainly changed into rotation of an output shaft at a reduced speed and a rise 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. This is especially popular where highly precise and accurate positioning is required, for instance in robotic applications, machine tools, and comparable applications. Cycloidal reducers also feature rolling as opposed to sliding contact, hence experiencing less overall put on.
