Clamping device for removable disks

摘要

A clamping device for clamping disks uses a flexible lock member, a hub, and a cap. The hub is mounted to a spindle, which defines a rotational axis for the hub. The upper portion of the hub has a recess including a guide in which the lock member is axially introduced. A clamping effect of the lock member in the recess is preferably achieved by selecting outer diameter of the lower portion of the lock member greater than the diameter of the cylindrical recess. The hub has a disk seating surface proximate to the base of the upper portion. The lock member is a unitary cap-shaped member made of flexible material, and preferably includes a plurality of axial fingers extending the disk-seating surface. The fingers are preferably a lower and an upper portion. The lower portion comprises an outer stiffening area forming a greater diameter than the upper portion.
