What is a cycloidal reducer?

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

Usual cycloidal speed reducers, such as 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 type of cam follower, typically a pin or needle bearings. The eccentric rotation of the cam is certainly transformed into rotation of an output shaft at a lower life expectancy speed and an increase in torque.

The main benefit 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 specific and accurate positioning is necessary, for instance in robotic applications, machine equipment, and similar applications. Cycloidal reducers also feature rolling instead of sliding contact, thus experiencing less overall wear.
