Abstract
Apparatus for clamping a plurality of axially spaced, rotatable elements such as a stack of actuator arms or magnetic storage discs in a disc drive. The rotatable elements are coupled to respective housings for rotation at a respective radius about associated, stationary shafts by bearing assemblies. As used in an actuator assembly, an actuator shaft bearing housing is inserted into an opening in each of the actuator arms and a clamp fastener exerts a clamping force on the actuator arms so as to secure the actuator arms relative to the actuator shaft bearing housing. The clamp fastener comprises a clamp fastener cylinder with an exterior surface which is fixably attached to a corresponding interior surface of the actuator shaft bearing housing. The clamping force is exerted by a clamp disc protruding in a radial direction from the clamp fastener cylinder, beyond the radius of the actuator shaft bearing housing. The clamp fastener can be used in a similar fashion to clamp a stack of magnetic storage discs in place around a spindle motor housing.
