Design
Taper clamping bushes are designed with a cylindrical bore and
a parallel keyway. A Taper clamping bush has a tapered outside
diameter and fits into the taper bore of the hub part. The Taper
clamping bush has a slot running along its length. To fit, half
blind holes are drilled in the Taper clamping bush, while on the
opposite side half thread turns are cut in the hub part. With the
aid of the fitting bolts, which are supported on the base of the
blind holes, the Taper clamping bush is pushed into the taper
bore. The Taper clamping bush is compressed, thus generating
a parallel key and clamp connection between shaft and hub
part.
To dismantle, the fitting bolts are removed and screwed into the
forcing-off threads. The forcing-off threads are cut half in the Ta-
per clamping bush and half in a blind hole in the hub part. When
the forcing-off bolts are fitted, the Taper clamping bush is forced
out of the taper hub bore. The connection is broken.
The Taper clamping bush and the fitting and dismantling bolts
are always screwed in from the larger outer diameter side of the
taper.
The torque is transmitted via the clamping connection and the
parallel key. No axial fixture is required with normal axial forces,
as the clamping connection is sufficient.
