ABSTRACT:
A spindle clamp for supporting a disk for rotation about an axis, the disk having a central aperture, in which fluid pressure actuates release of the disk and split jaws clamp the disk in the absence of fluid pressure. The clamp includes a hub which is rotatable about a central axis, an annular jaw split into a plurality of jaw pieces and disposed in a trough defined in the hub. A cap is spring biased downward against the jaw pieces. A central cone located radially inward from the trough defines a wedge surface. O-ring springs bias the jaw pieces inward into engagement with the wedge surface. Fluid pressure applied through passageways in the hub against a diaphragm causes the diaphragm to bulge upward against the jaw pieces, releasing the disk.
