Abstract

Resilient pads and cantilevered tabs are provided to secure disk member 11 to drive shaft 12 through a spacer ring 13. Each element 11, 12 and 13 has a different coefficient of thermal expansion. Three L shaped slots are cut in disk 11 to produce three cantilevered tab members 16. The tip of each tab 16 is pinned to ring 13 to provide a cantilever spring. The latter has maximum rigidity in the circumferential direction and maximum compliance in the radial direction.

Disk Mounting

Resilient pads and cantilevered tabs are provided to secure disk member 11 to drive shaft 12 through a spacer ring 13. Each element 11, 12 and 13 has a different coefficient of thermal expansion. Three L shaped slots are cut in disk 11 to produce three cantilevered tab members 16. The tip of each tab 16 is pinned to ring 13 to provide a cantilever spring. The latter has maximum rigidity in the circumferential direction and maximum compliance in the radial direction.

Ring 13 in turn is compliantly mounted on shaft 12 by three resilient pad members 17. Pads 17 are adjustably pinned to ring 13 so that they can be forced against shaft 12 to place all the eccentric pads in compression. These pads act as stiff compression springs to take up any radial displacement between ring 13 and shaft 12 resulting from temperature changes. Pads 17 thus absorb the effect of differential thermal expansion between shaft 12 and ring 13. Tabs 16 absorb the effect of differential thermal expansion between disk 11 and ring
13.
