ABSTRACT:
The present invention includes 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.
