The bearing fixing device and the hybrid power module comprising the bearing fixing device can simplify the installation process and reduce the manufacturing precision requirements of a shaft, a bearing and other fixing parts.)

A bearing retainer for fixedly mounting a bearing on a shaft, the bearing retainer comprising:

a radially outward projecting portion that projects radially outward from an outer peripheral surface of the shaft and abuts against one axial side of an inner ring of the bearing;

an annular elastic member provided between the inner race of the bearing and the shaft for circumferentially fixing the inner race of the bearing relative to the shaft; and

and the stop piece is fixedly connected with the shaft and is abutted against the other axial side of the inner ring of the bearing so as to axially fix the inner ring of the bearing relative to the shaft.

The bearing fixture apparatus of claim 1,

the stop member is formed as a retainer ring that is fitted over the shaft.

The bearing fixing device according to claim 1 or 2,

the stop member is formed as an elastic collar fitted over the shaft and capable of elastic deformation in the radial direction, and

the shaft is provided with an annular groove on an outer circumferential surface, and the stopper is accommodated in the annular groove.

The bearing fixture of claim 3, wherein the stop comprises:

an annular body portion fixedly connected to the shaft;

a deformation portion connected to one end of the annular body portion axially close to the inner race of the bearing and extending obliquely outward in a radial direction, the deformation portion being elastically deformable in the radial direction.

The bearing fixture of claim 1 wherein

An annular groove is formed in the inner circumferential surface of the inner ring of the bearing or the outer circumferential surface of the shaft, and the annular elastic member is arranged in the annular groove.

A bearing fixing device according to claim 1 or 5, wherein

The annular elastic member is formed as an annular rubber ring.

The bearing fixture of claim 1 wherein

The annular elastic member is formed as an annular elastic film which is disposed between the inner ring of the bearing and the shaft and wraps the outer circumferential surface of the shaft.
