flywheel and the clutch, but also the axial forces generated
by the release force when disengaging.
Ball bearing
When development of the DMF started, large ball bearings
could be used because of the relatively simple design of
the internal components. However, the constantly rising
demands on the rotary vibration damping made addi-
tional components necessary in the DMF. For this reason,
further construction space had to be created. This led to a
systematic reduction of the diameter of the ball bearing.
Small ball bearings allow the space-neutral integration
of additional rotary vibration dampers and, in this way,
increase the efficiency of the DMF.
The bearing in the primary mass serves as a rotating
connection with the secondary mass. It not only has to
absorb the weight-related radial forces of the secondary
Types of bearings
Two different types of bearings can be used on a DMF:
Plain bearing
In comparison with ball bearings, plain bearings take
up less space and are more simply designed. In spite of
their low manufacturing costs, they can be universally
used and, if necessary, can be designed to allow axial
motion.
