Description of Z7A Locking Device
The main purpose of the expansion sleeve is to exchange the function of splines and one keys, so as to comprehend the relationship between the components (this kind of as gears, flywheels, pulleys, etc.) and the shaft to transmit the load.
When it is utilized, by means of the motion of high-power bolts, a huge keeping pressure is generated between the interior ring and the shaft, and in between the outer ring and the hub. When under load, torque, axial drive, or the combined load of the two is transmitted by the merged force of the expansion sleeve and the areas and the accompanying frictional drive.
