The roller-type overrunning clutch is divided into two types: outer star wheel and inner star wheel, based on the position of its inner yoke (star wheel). The so-called yoke refers to the conjugate surface between the cylinder and the cylindrical hole, while the star wheel is a component that has grooves to accommodate the rollers.
The wedge block overrunning clutch uses a specially shaped wedge block instead of rolling pins as the wedging component. It is a type of clutch that consists of a wedge block and inner and outer raceways forming a friction pair.
The overrunning clutch is a fundamental component that has emerged with the development of mechatronic products. It is an important part used for the power transmission and separation function between the prime mover and the working machine, or between the driving shaft and the driven shaft within a machine.
