Abstract
An armature of an electromagnetic clutch is connected to a mounting plate which is coupled to the toothed driven hub of the clutch through the intermediary of an elastomeric spider. If the spider is melted by heat, the mounting plate wedges against the tips of the teeth of the hub and is prevented from flying axially off of the forward end of the hub.
Claims9
An armature assembly for an electromagnetic coupling, said assembly comprising a forwardly disposed mounting plate and a rearwardly disposed armature, means connecting said armature and said plate for rotation in unison while permitting said armature to move toward and away from said plate, a hole extending axially through said plate, the periphery of said hole being defined by a first set of circumferentially spaced teeth and by a first set of circumferentially spaced valleys which alternate with the teeth, a hub having a second set of circumferentially spaced teeth and having a second set of circumferentially spaced valleys which alternate with the second teeth, said hub being telescoped into said hole with the teeth of each set being disposed within the valleys of the other set, elastomeric material disposed between said first and second teeth and coupling said plate and said hub for rotation in unison, the tips of the teeth of one of said sets and the bottoms of the valleys of the other of said sets being shaped so as to be engageable with one another with a wedging action upon forward shifting of said plate relative to said hub thereby to captivate said plate against forward separation from said hub.
