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.

Installation Note
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
