END RETAINER RING ASSEMBLY FOR ROTARY ELECTRICAL DEVICES ABSTRACT OF TEE DISCLOSURE A rotary electrical device has a rotor body for receiving an inner retaining ring. A primary retaining ring is formed of a composite of epoxy and graphite fibers and has an integrally embedded auxiliary ring at one end thereof adjacent its open end. The auxiliary ring and inner retaining ring have complementary tapered surfaces with axially spaced, circumferentially extending seals therebetween. The inner retaining ring has fluid lines for receiving fluid under high pressure to facilitate axial assembly and disassembly of the retaining ring relative to the rotor body. The retaining ring has a corrugated spring to accommodate differential expansion of the end windings of the electrical device and the composite retaining ring. A short-circuiting ring is at the inside diameter of the primary retaining ring. A corrugated spring is interposed between the primary retaining ring and the short-circuiting ring.
