Abstract
An eccentric gearing type clutch includes a housing connected to, and for rotation with, a drive shaft; at least one set of rotors, each set of rotors having two parallelly arranged rotors concentric with the housing and being connected to, and for rotation with, a driven shaft; at least one set of cylinder rings cooperating with respective rotors, each set of cylinder rings having two cylinder rings arranged in parallel and located between the housing and respective rotors, and being capable of upward and downward displacement inside the housing, the two cylinder rings being separated by a separator plate; a vane movably arranged in a slot in each rotor; and a joint control mechanism for controlling upward and downward displacement of the two cylinder rings, wherein space inside the housing is filled with an operation oil and sealed. Reduced frictional wear provides improved clutch performance, enhanced lifespan and braking accuracy.
