Patent ID: 7909514

Claim:
A bearing arrangement for a shaft rotating about an axis, comprising: an outer bearing race; an inner bearing race including a first half-race fastened to the rotating shaft and a second half-race; rolling elements arranged between the outer bearing race and the inner bearing race; a maintaining unit which maintains said two half-races together; and a retention piece fastened to the rotating shaft and which retains the second half-race, wherein said maintaining unit breaks or deforms when the bearing is subjected to a misalignment or a moment above a predetermined value, so as to allow an axial displacement of the second half-race with respect to the first half-race, and wherein the retention piece is a piece of revolution which includes a fastening collar which fastens the retention piece to the rotating shaft, a support ring extending circumferentially which radially supports the second half-race after the axial displacement thereof, a conical body which connects the support ring to the fastening collar, and an axial blocking flange extending radially which blocks the second half-race axially after the axial displacement thereof.
