The clamping sleeves allow the firm attachment of rotating elements (pulleys,
gears, flywheels) to the shaft. The bushing is inserted into the cylindrical bore
in the hub and this assembly is slid and seated on the shaft. Tightening
of the housing mounting bolts, the sliding cones act on each other, which
expand the walls of the housing and exert a clamping pressure on the shaft
and the hub. The bushings are capable of removing the bore tolerance and the element accurately
centred. This type of clamping does not use a locking pen and is not
There is no need to spline the shaft and hub.
When removing the clamped element, the mounting screws are first unscrewed
from the housing and then screwed back in, but into the removal holes.
The pressure exerted by tightening these bolts will pull the housing cones apart.
