Z9 41Cr4 Shaft Locking Device Expanding Hub
Overview
Expanding hub is an advanced basic component widely used for mechanical coupling under heavy loads in the world today. In the coupling of wheel and shaft, it is produced by tightening high-strength bolts to make the containment surface A keyless coupling device that realizes load transmission by pressure and friction.

Z9 Expanding Hub Diagram
The shaft locking device should be tested before coupling to ensure that there are no other impurities on the surface of the product, preferably cleaned in special oil and coated with lubricant for backup; then expand the sleeve into the connection hole to ensure that the tightened screws are placed smoothly and the whole process ensures that the shaft locking device Maintain a horizontal position to prevent tilting; external parts such as gears and sprockets that match the shaft locking device should be tightened with a spanner, i.e. the installation is complete.
The dismantling process of the shaft locking device is relatively simple, first loosen the screws to remove the galvanised screws, using a cover plate to protect against rusting, and then tap the expansion of the transmission parts to remove the shaft locking device, the whole process requires control of reasonable strength to prevent the shaft locking device deformation and jamming
