Embodiment Construction

[0036] Figure 4 The partially shown machine 1 according to the invention comprises a shaft 2 which turns about an axis X of rotation.

[0037] Machine 1 is, for example, an electric motor.

[0038] The shaft 2 is engaged in a bearing 10 comprising an inner race 11 , an outer race 12 and rolling elements 13 arranged between the races 11 and 12 .

[0039] In the example considered, the rolling elements 13 are rollers, but the invention is not limited to a particular type of bearing, and the rolling elements may be balls.

[0040] The inner race 11 is fixed axially on the shaft 2 by retaining rings 3 and 4 fitted in corresponding grooves 5 and 6 of the shaft 2 . In a variant, this fixation is achieved in a different way, for example due to a protrusion on the shaft.

[0041] The outer race 12 is carried by a bearing mount 20 of the machine which has an opening through which the shaft passes.

[0042] The bearing mount 20 has a housing 21 in which the outer race 12 of the bea...

Abstract

The present invention concerns a rotary machine (1) comprising: at least one bearing mount (20); at least one bearing (10) carried by the bearing mount (20), the bearing comprising inner (11) and outer (12) races and rolling elements (13) between the races; a shaft (2) engaged in the bearing, axially blocked relative to the inner race; a pushrod cover (30) arranged on one side of the bearing, having a surface (31) opposite the bearing and having, on its radially outer edge, a bead of material (33) in contact with the outer race (12); at least one push element (40) moveable transversely to theaxis of rotation (X) of the shaft (2) in order to exert a pressure on said surface (31) of the push rod cover in order to press it against the outer race (12) and axially block said outer race.

Description

technical field [0001] The present invention relates to rotating machines comprising a shaft engaged in at least one bearing carried by a bearing mount, and more particularly but not exclusively to electric rotating machines such as motors or alternators. Background technique [0002] It may be necessary to axially block the bearings in corresponding bearing mounts. [0003] JP S59 53053 discloses a device for adjusting the axial position of a rotating shaft after assembly in an electric motor. [0004] US 5 001 377 describes a lubrication system for antifriction bearings supporting a rotating shaft in an electric motor. [0005] DE 198 24 382 A1 discloses a gear unit with a worm comprising at least one worm shaft displaceable in an axial direction. [0006] US 3 147 050 describes a bearing mount assembly arrangement for a rotating machine for retaining a bearing mount in a housing of the bearing mount. [0007] Such as figure 1 and figure 2 As shown, the first approac...
