Z11 42CrMo4 Shaft Locking Device Expandable Hub
Overview
The expandable hub is a keyless coupling device. Its principle and
purpose are to generate huge holding force between the inner ring
and the shaft, and between the outer ring and the hub through the
action of high-strength tension bolts to realize the mechanism and
the shaft. The keyless connection. When under load, the torque,
axial force or the combined load of the two are transmitted by the
combined pressure of the expansion sleeve, the machine part and the
shaft and the accompanying friction force.
