ABSTRACT:
A lamination stack assembly is provided comprising elongated, resilient spring pin members for exerting radially outward force when in deformed states; a rotational member having an outer surface; and a plurality of laminates, each having an inner edge defining an opening for receiving the rotational member. The spring pin members are disposed axially along the rotational member intermediate of the outer surface of the rotational member and the inner edge of the laminates, and cooperate with the rotational member and the inner edges of the plurality of laminates to prevent relative rotational slippage of the laminates with respect to the rotational member. The shaft preferably includes axially extending grooves for receiving the spring pin members which cooperate with notches in an inner edge of each of the plurality of laminates to receive the spring pin members. Each of the spring pin members preferably includes a hollow cylinder having an exterior wall defining an axially extending gap in the wall, wherein the gap varies in width from a normal state to a deformed state. Preferably, the spring pin members are made of hardened steel.
