Abstract
The utility model relates to a flexible transmission decelerator used for industrial power transmission, wherein a friction transmission device is additionally provided based on gear transmission and the flexible transmission function can be realized by means of the cooperation of an external hydraulic auxiliary device. Controllable high pressure working oil is led into the internal oil-way of equipment through a swivel joint so as to enter the working oil pocket of a clutch. The pressure oil pushes a piston to move and compresses a friction plate assembly, so that the frictional force is generated between a friction plate and a steel disc. Therefore, relative transmission parts are driven to operate and the power output is realized. When the pressure of the working oil changes slowly, the frictional force generated between the friction plate and the steel disc slowly changes correspondingly. Therefore, the slow change of the output speed can be controlled and the flexible transmission is realized.
