ABSTRACT:
A clamp ring for a disk stack assembly of a computer disk drive unit includes a lower surface which includes an arcuate rolling contact surface that uniformly distributes a load applied to the clamp ring to components of the disk stack assembly underlying the clamp ring without damaging such disk stack components on load-induced flexion of the clamp ring. A cantilevered section of the clamp ring is disposed radially inwardly of the arcuate rolling contact surface, and is defined by a portion of the lower surface which is raised relative to an adjacent portion of the arcuate rolling contact surface so as to not contact the underlying disk stack components on load-induced flexion of the clamp ring. In use, the clamp ring is heated and then placed over the disk stack components to be clamped together. An axial load is applied to the clamp ring which causes it to flex and thus move contact between the lower surface of the clamp ring and the underlying disk stack components radially along the arcuate rolling contact surface. The axial force is maintained until the clamp ring cools sufficiently to hold the clamp ring in place, and then the axial load is removed.
