Abstract

The mechanism mounts a stack of flexible disks 12 with respect to a stack of hubs 10, with the disks 12 being interleaved loosely between hubs 10, and comprises rod 14 of rubber or rubber-like material functioning as a slightly yielding connection between disks 12 and hubs 10.

Flexible Disk Mounting Mechanism

The mechanism mounts a stack of flexible disks 12 with respect to a stack of hubs 10, with the disks 12 being interleaved loosely between hubs 10, and comprises rod 14 of rubber or rubber-like material functioning as a slightly yielding connection between disks 12 and hubs 10.

Each hub 10 is formed with a relatively thick central portion 10a and a relatively thin peripheral flange portion 10b providing slots 16 between hubs 10. One of disks 12 is positioned in each of slots 16 and has an inside diameter greater than that of the associated hub portion 10a and has a thickness less than that of the slot 16 so that there may be a shifting of the disk 12 with respect to hubs 10. Rod 14 extends through coaxially disposed holes in flange portions 10b and in disks 12 as well as in a clamping plate 18, disposed at the top of the stack of hubs 10, for rotatably fixing disks 12 with respect to the stack of hubs 10.

A slug 20 of rubber-like material is used to form rod 14, and slug 20 has a relatively small diameter portion 20a on one end. Slug portion 20a is smaller in diameter than the holes through plate 18, disks 12 and hubs 10 and serves as a leader by means of which slug 20 may be pulled in direction A through these holes. Slug 20 is stretched to decrease its diameter to facilitate its movement through the aligned holes of hubs 10, plate 18 and disks 12. After the relatively thick portion of slug 20 is within these aligned holes, the tension on slug 20 is relaxed. The relatively thick diameter portion of slug 20 then expands and fills the column of holes in plate 18, dis...
