The working principle of locking disk is through the action of high-strength bolts, so that the inner ring and the shaft, the outer ring and the hub to produce a huge clamping force, so as to realize the transfer of loads.

The working principle of locking disk is to make the inner ring and the shaft, the outer ring and the hub through the action of high-strength bolts to produce a huge clamping force, so as to realize the load transfer.

The locking disk is a keyless coupling device used for the coupling of wheels and shafts. It achieves load transfer by tightening high-strength bolts to create pressure and friction between the accommodating surfaces. This device eliminates the need for a keyed coupling and is suitable for use in the connection between a machine and a shaft for load transfer. When the device is subjected to a load, the combined pressure and friction between the expansion sleeve and the machine part transmits torque, axial force, or a composite load of the two. The locking disk plays an important role in the coupling of wheel and shaft, realizing the locking and releasing of the shaft through friction, and is widely used in various mechanical equipment, such as the start-stop control of conveyor belts, agitators, cutters, and other equipment, as well as the engine of the transmission system of automobiles, trains, and other vehicles with wheel Start-stop control.

The design and installation steps of the locking disk also need to pay attention to some key points. For example, the locking area on the hollow shaft should not have any grooves to ensure efficient load transfer. During installation, if the stiffnesses are similar, the bolts should be tightened alternately and evenly to ensure uniform pressure distribution. In addition, the locking disk is as easy to remove as it is to install. By loosening the screws, the mating surfaces are automatically relaxed, and the shaft, bushing, and inner ring of the locking disk can be restored to their original dimensions and clearances for easy maintenance and replacement.

In summary, the principle of operation of the locking disk is based on friction, and the operation of the control mechanism adjusts the friction between the locking disk and the shaft to achieve locking and release of the shaft. This device plays a key role in industrial applications, ensuring the stable operation of mechanical equipment and the efficient transfer of loads
