Abstract
A device for centring and guiding the rotation of a turbine engine shaft, in which the outer race of a bearing is retained axially upstream and downstream by a retaining mechanism cooperating with a bearing bracket and with a coupling mechanism including elastically deformable mechanism connecting the outer race to the bearing bracket, the retaining mechanism being separate from a protecting ring of the device. A method of assembling such a device is also described. The retaining mechanism is pre-assembled with the coupling mechanism prior to the final assembly of the coupling mechanism with the bearing bracket. The device and the method have the combined advantages of axially retaining the outer race in two opposing directions and having a particularly straightforward assembly.
