Embodiment Construction

[0013] With reference to the drawings, the assembly 1, 2 in which the rotating shaft 3 is fitted in the housing 4 through bearings and the assembly including the rotating shaft 3 will be described below, wherein two axially spaced parts are mounted in the housing 4 through each bearing .

[0014] In particular, the rotating shaft 3 may be an axle wheel of an electric motor of a motor vehicle, wherein one part is locked in a housing 4 and the other part of said shaft is axially movable relative to the other housing 4 .

[0015] The bearing comprises a fixed outer ring 5 and a rotating inner ring 6 between which, in the embodiment shown, rolling elements 7 in the form of balls are arranged for enabling relative rotation of said rings .

[0016] The fittings 1, 2 have an annular accommodation defined between the inner bearing surface 8 of the housing 4 and the outer bearing surface 9 of the shaft 3, in which annular accommodation the bearing is arranged, clamped around the outer...

Abstract

The invention relates to assembling members (1, 2) using bearings to assemble a rotating shaft (3) in a housing (4). Each bearing comprises an outer ring (5) and an inner ring (6), each assembling member has an annular accommodation part defined between an inner bearing surface (8) of the housing (4) and an outer bearing surface (9) of a shaft (3), the bearing is arranged in the annular accommodation part, he inner ring (6) is mounted in a clamping manner surrounding the outer bearing surface (9), the thermal expansion of the outer ring (5) is lower than that of the inner bearing surface (8), each assembling member also comprises a sleeve (10) made of thermoplastic material, the sleeve in inserted between the inner bearing surface (8) and the outer ring (5), the thermal expansion of the sleeve is larger than that of the outer ring (5), the sleeve has an annular geometrical shape which is broken by a slot (11) in a circumferential direction, so that the diameter of the sleeve can be changed, and under the ambient temperature, radial clearances are formed between the inner bearing surface and the sleeve and / or between the sleeve and the outer ring.

Description

technical field [0001] The invention relates to an assembly for fitting a rotating shaft in a housing with a bearing comprising an outer ring and an inner ring, such that rolling elements capable of relative rotation of the outer ring and the inner ring are arranged between the outer ring and the inner ring . [0002] The invention also relates to an assembly comprising a rotating shaft, wherein the two axially spaced apart parts are respectively mounted in a housing via bearings. Background technique [0003] To this end, the fitting comprises an annular housing defined between an inner bearing surface of the housing and an outer bearing surface of the shaft, said bearing being arranged in said annular housing and having an inner ring clampingly mounted around the outer bearing surface . [0004] The outer ring may be mounted in the inner bearing surface with an interference fit sufficient to clamp said ring radially in said inner bearing surface so as to axially lock the...
