Bearing support

A method of manufacturing a bearing support comprising the steps of:

• limiting relative axial movement between a damper ring operable to receive an outer race of a bearing assembly and a pilot ring operable to be substantially-fixed in operation with a fuse pin extending through aligned apertures in the damper ring and the pilot ring, the fuse pin operable to prevent relative radial movement between the pilot ring and the damper ring up to a predetermined amount of loading, wherein the fuse pin is operable to fracture in response to loading beyond the predetermined amount;
• limiting relative axial movement between the pilot ring and the damper ring with a retainer extending through one of the damper ring and the pilot ring and fixed to the other of the damper ring and the pilot ring, the retainer limiting relative axial movement between the damper ring and the pilot ring when the fuse pin fractures in response to loading beyond the predetermined amount;
• and
• engaging the fuse pin with at least one of the damper ring and pilot ring through a heat shrink fit.

A turbine engine comprising:

• a shaft operable to rotate about a centerline axis;
• a bearing assembly supporting said shaft for rotation and having an inner race fixed to said shaft, a plurality of rollers disposed about said inner race, and an outer race encircling said plurality of rollers;
• a damper ring operable to receive said outer race of a bearing assembly and encircling said centerline axis;
• a pilot ring encircling said centerline axis and operable to be substantially-fixed in operation;
• a fuse pin extending through apertures in said pilot ring and said damper ring to prevent relative radial movement between said pilot ring and said damper ring up to a predetermined amount of loading, said fuse pin operable to fracture in response to loading beyond the predetermined amount;
• a retainer extending through one of said pilot ring and said damper ring and fixed to the other of said pilot ring and said damper ring, said retainer and operable to limit relative axial movement between said pilot ring and said damper ring, said retainer limiting relative axial movement when said fuse pin fractures in response to loading beyond the predetermined amount;
• and
• wherein said fuse pin is engaged with at least one of said pilot ring and said damper ring through a heat shrink fit.
