The bearing support (64) includes a pilot ring (68) encircling an axis of rotation (24). The pilot ring is operable to be substantially-fixed in operation. The bearing support also includes a damper ring (66) operable to receive an outer race of a bearing assembly. The damper ring also encircles the axis of rotation. The bearing support also includes a fuse pin (70,70a) extending through aligned apertures in the pilot ring and the damper ring to prevent relative radial movement between the pilot ring and the damper ring up to a predetermined amount of loading. The fuse pin is operable to fracture in response to loading beyond the predetermined amount The bearing support also includes a retainer (78a) extending through one of the pilot ring and the damper ring and fixed to the other of the pilot ring and the damper ring. The retainer is operable to limit relative axial movement between the pilot ring and the damper ring. The retainer limits relative axial movement when the fuse pin fractures in response to loading beyond the predetermined amount. The fuse pin is engaged with at least one of the first and second apertures through a heat shrink fit. |
