Z20 Keyless Locking Device Power Lock Assembly
Products Features
The z-series locking assembly produced by Changzhou tianniu transmission company is a keyless connection structure. Under the action of axial force, the inner and outer sleeves shrink and expand closely with the shaft and hub to produce enough friction to transmit torque and axial force, so as to achieve the purpose of mechanism operation.
Features: good centering performance of connection; No heating is
required during assembly; It is convenient to disassemble or adjust
the relative position between the shaft and the hub; No stress
concentration; Strong bearing capacity. Usage: when the hub is
connected with the shaft, it plays a tight closing role after being
tightened by bolts. Because the product is a conical surface or
conical structure, it changes into radial force through axial force
movement, resulting in friction and meeting the torque
requirements. When disassembling, loosen all the bolts. There is no
need to remove the bolts. Then screw the appropriate bolts into the
disassembly hole with an Allen wrench and loosen the disassembled
parts
