ABSTRACT:
A flywheel assembly having a first flywheel, a second flywheel, a viscous damper mechanism (3) disposed therebetween, and a boss member (5). The second flywheel is supported on the first flywheel so as to be relatively rotatable via the viscous damper mechanism. The viscous damper mechanism (3) includes disc-shaped plates (9), each having radially inner serrations (9d) on radially inner surface thereof. The boss member (5) has radially outer serrations (5a). The boss (5) and plates (9) are provided with a thermal expansion differential prior to assembly. After assembly, the serrations (5a) on the boss securely engage the serrations (9d) on the inner surface of the plates (9). The plates (9) may be heated or the boss (5) may be cooled to provide a thermal expansion differential.
