The main purpose of the locking assembly is to replace the function of splines and single keys, so as to realize the connection between the parts (such as gears, flywheels, pulleys, etc.) and the shaft to transmit the load.
When locking assembly is used, through the action of high-strength bolts, a huge holding force is generated between the inner ring and the shaft, and between the outer ring and the hub. When under load, torque, axial force, or the combined load of the two is transmitted by the combined pressure of the expansion sleeve and the parts and the accompanying frictional force.
