Abstract:
A spindle clamp for removably supporting a disk having a central aperture, said spindle clamp comprising:a hub having a rotational axis and a disk-seating surface, wherein said hub includes an axially-arranged recess; and a lock member having an axis generally coinciding with said rotational axis, wherein said lock member includes at least a flexible upper portion to allow expansion in a radial direction being exclusively caused by a force applied to a cap in an axial direction, and retracting in a base position when said force is removed, wherein said lock member is axially-arranged in said hub such that said upper portion of said lock member exceeds said disk-seating surface of said hub to provide both axial and radial restraint of said disk, wherein said cap provides a force to said upper portion of said lock member and further includes means for providing a force to said cap, wherein said cap is arranged at a piston, wherein said piston fits into a bore of said hub, and said cap and piston are released from said hub with an inserted removal member having a plurality of pins for pushing said cap and piston out of said hub.
