Taper
Bushes
Taper bushes provide a low cost, simple, quick method of securing
sprocket, pulleys and couplings to a wide range of
standard metric and imperial dimensioned shafts of general
commercial tolerances and finish.
The taper surfaces on the bush and mating hub are driven
together by high tensile screws, causing the split bush to be
firmly contracted onto the shaft. The strong clamping force
which can be achieved enables transmission of high torque
without the problems of fretting associated with simple
keyseated drives.
