ABSTRACT:
An electromagnetic friction coupling includes an armature assembly, a pole assembly and a coil energizable to effect engagement of the armature and pole assemblies. The armature assembly includes an armature plate and a hub member which are coupled together by means for compensating for misalignment between the armature plate and hub members. The hub member is adapted to be connected to a shaft for rotation therewith and the armature member is disposed coaxially of the hub member and is connected for rotation therewith. The hub member and armature plate include outer and inner surfaces, respectively, which include a plurality of substantially semicircular recesses disposed therein. Each of the recesses disposed on the armature plate and the complementary recesses on the hub member define a plurality of substantially cylindrical openings therebetween each of which is adapted to receive a rotatable cylindrical pin therein to couple the hub member and armature plate. The cylindrical pins are loosely disposed in the cylindrical openings to provide for angular and radial movement of the armature plate and hub member relative to each other while compensating for angular and radial misalignment of the hub member and armature plate. The cylindrical pins are free to rotate within the cylindrical openings to distribute the wear thereon evenly about the outer surface thereof and are deformable to provide for uniform loading while compensating for misalignment of the armature plate and hub member.
