What is the locking principle of the locking disc?

Extend the coupling sleeve (referred to as the expansion sleeve) and lock the coupling disc (referred to as the locking disc).

Principle; in the coupling of the wheel and the shaft, it is a keyless coupling device that achieves load transmission by tightening high-strength bolts to generate pressure and friction between the bearing surfaces to realize the parts (such as gears, flywheels, pulleys, etc.) ) A coupling to the shaft to transfer the load. When it is used, it exerts a huge holding force between the inner ring and the shaft and between the outer ring and the hub through the action of the high-strength bolt; when the load is applied, the combined pressure of the expansion sleeve and the machine member and the accompanying friction force Transfer torque, axial force or a composite load of both.
