ABSTRACT:
An armature disc is attached to a resilient plastic spider by angularly spaced rivets. To prevent the spider from striking the disc and creating a buzzing noise, spacer pads are formed integrally with the spider adjacent the rivets and establish an axial gap of substantial width between the disc and the spider along arcs located between the rivets. The heads of the rivets are located in countersunk holes in the spider and pull axially through the plastic of the spider to release the armature disc from the spider if the spider becomes excessively hot as a result of slippage of the coupling. A metal washer on the hub of the coupling prevents the hot disc, when released, from dropping onto and melting a central sleeve portion of the spider.
