ABSTRACT:
An armature assembly in an electromagnetically actuated braking mechanism and including a circular armature plate having a central opening defined by a circumaxial series of radially inwardly extending armature teeth. The inner ends of the armature teeth cooperate to define a coaxial crest circle. A plastic hub, molded in place on the armature plate, substantially encapsulates the armature teeth and has a coaxial central opening defined by a circumaxial series of spline teeth which define a root circle having a diameter greater than the diameter of the crest circle. Equiangularly spaced fan blades integrally connected to the central portion of the hub project radially outwardly therefrom adjacent one face of the armature plate. A resilient split clamping ring coaxially surrounds and exerts radially inwardly directed biasing force upon projecting end portions of the spline teeth which extend axially outward beyond the one face of the armature plate to urge the spline teeth into engagement with a spline on an associated shaft.
