Description of Z7B Locking Device
The principal function of the expansion sleeve is to substitute the perform of splines and single keys, so as to comprehend the connection between the parts (such as gears, flywheels, pulleys, and many others.) and the shaft to transmit the load.
When it is employed, by means of the motion of large-strength bolts, a huge keeping force is produced among the internal ring and the shaft, and in between the outer ring and the hub. When underneath load, torque, axial force, or the mixed load of the two is transmitted by the combined stress of the expansion sleeve and the areas and the accompanying frictional pressure.
