Patent ID: 8317202

Claim:
A ring for mounting a structure to a shaft, the ring comprising: a first portion having a first surface adapted to mount the structure to the ring; and a radially inner portion being deformable to accommodate movement of the shaft in response to a load from the shaft; two radially extending portions extending substantially parallel to one another and substantially perpendicular to an axial direction through the ring prior to mounting, said radially extending portions connecting said inner portion and said first portion, said radially extending portions, said inner portion and said first portion bounding an internal cavity, said cavity deformable in response to the load such that said inner portion and said first portion move closer to each other; the radially inner portion comprising an inner surface having a plurality of indentations to engage and rigidly mount the ring to the shaft wherein the structure rotates with the shaft; and the radially inner surface having the plurality of indentations being flexible for flexibly engaging the shaft to substantially prevent the rotation of the shaft relative to the ring under a load.
