Mechanically Expandable Shrink Ring Disk Clamp

      A mechanically expandable shrink ring provides a means of
clamping and unclamping a disk stack without the use of a heating
process.

      The shrink ring (see the figure) is designed for both assembly
and removal.  To assemble, a tool applies a radial load to the outer
diameter of the groove 1 thus expanding the inner ring diameter 2
radially until it has sufficient clearance to slide over the spindle
hub.  An axial load is then applied to the ring at point 3 which is
in contact with the disk stack at point 4.  The radial load is then
released allowing the shrink ring to contract radially and seize onto
a spindle hub, clamping the disk stack.  For disassembly the process
is reversed.
