Locking Assembly

QY918

The locking assembly is widely used in the world as a transmission product with a keyless connection structure. Under the action of the axial force, the inner sleeve of the expansion sleeve shrinks and expands to make the shaft and the hub closely fit. Generate enough friction to transmit torque and axial force, so as to achieve the purpose of the operation of the mechanism. The expansion and tightening coupling sleeve has good centering performance of the connection, no heating, disassembly or adjustment of the relative position of the shaft and the hub during assembly is convenient, no stress concentration, strong bearing capacity, large torque, good stability, high precision, and no damage to the mating surface Features.
