  • Disc clamp with shape memory alloys
    Patent number: 6590739
    Abstract: A disc clamp made from a shape memory alloy is configured for tight fit between an upper ledge of a spindle hub and the upper surface of a disc when the disc clamp is in an austenitic phase. In a martensitic phase, the disc clamp is configured for easy assembly over the spindle hub. The disc of the present invention provides for uniform distribution of clamping forces on the disc, and avoids the need for threaded holes in the spindle hub.
