Abstract

The figure illustrates a design for assembling disks to a spindle system in a direct access storage device (DASD) by radial clamping. This is in marked contrast to the conventional shrink ring or screw down clamp.

Disk Pack Assembly Design

The figure illustrates a design for assembling disks to a spindle system in a direct access storage device (DASD) by radial clamping. This is in marked contrast to the conventional shrink ring or screw down clamp.

The figure shows that a split aluminum ring 1 has grooves machined in it at the proper spacing for the disks. Two options are a "v" groove 2 or a square cut groove 3. Split aluminum ring 1 is squeezed to allow it to be slipped into the inner diameter of the disks. When released, ring 1 expands to locate and hold the disks in position 4. Aluminum ring 1 is then placed on a hub 5. Two possible methods of accomplishing this are a shrink fit or a bond.
