うになっている。2. Description of the Related Art A rotating shaft of an electric device such as an electric motor having a rotating shaft is supported on both sides by a ball bearing mounted on the casing side as disclosed in, for example, JP-A-63-295900. The bearing receives a force in the radial direction, and is composed of an outer ring fitted into a bearing housing formed on the casing side and an inner ring fitted with a rotating shaft and rotating together with the rotating shaft. Balls or rollers are interposed between them so that they can relatively rotate in the circumferential direction.

り外輪が固着された状態に取り付けられている。The bearing device having the above-mentioned structure is usually assembled so that there is no relative slip between the outer ring and the bearing housing and between the inner ring and the rotary shaft. Therefore, in many cases, the bearing itself is attached to the bearing housing in a state in which the outer ring is fixed by press fitting or adhesion.

が問題になってくる。When the rotating shaft is supported on both sides by the bearing device as described above, when the rotating shaft expands under the influence of heat, the inner ring on the rotating shaft side and the bearing housing side A stress due to an axial force is applied between the outer ring and the outer ring, which may cause damage to the bearing. Therefore, there are some bearings in which the outer ring is not fixed to the bearing housing and a small clearance is set so that the above-mentioned stress is not applied, but in the end, the relative slip in the rotational direction is caused between the outer ring and the bearing housing. Occurs steadily due to the rotation of the rotating shaft, so heat generation and wear due to friction between the two become a problem.

のである。In the bearing device according to the present invention, an outer ring of a rolling bearing is radially attached with an annular ring having a projection or a recess formed in a part in the circumferential direction, and the ring is extended in the axial direction. A bearing housing that holds a rolling bearing by permitting a minute movement is provided with a locking portion that hits a protrusion or a recess of an annulus and restricts rotation of the annulus and an outer ring in the bearing housing.

The bearing device shown by 1 comprises a radial type rolling bearing 2 that rotatably supports the rotating shaft 1, a bearing housing 3 that holds the rolling bearing 2, and a creep restricting member. The creep restricting member is an annular ring 6 that is attached to and fixed to the outer ring 4 of the rolling bearing 2 and has a protrusion 5 that protrudes in the radial direction in a part of the circumferential direction, and constitutes a substantial bearing outer ring. . The bearing housing 3 is a ring 6
The rolling bearing 2 attached with the above is configured to have a size that allows a minute movement in the axial direction to be accommodated, and a part of the roller bearing 2 protrudes inside the outermost periphery of the protrusion 5 of the annular ring 6 in the accommodated state. A locking projection 7 that contacts the portion 5 is integrally provided.

増すことになる。In the bearing device having the above construction, the rolling bearing 2 is set in the bearing housing 3 by the ring 6 attached to the outer ring 4.
To function by fitting the rotary shaft 1 into the inner ring 8. That is, since the annular ring 6 is fitted in the bearing housing 3 while allowing a slight movement in the axial direction, the axial stress due to thermal expansion of the rotating shaft 1 is applied to the rolling bearing 2.
It does not take. Further, the annular ring 6 integrated with the outer ring 4 can creep due to the rotation of the rotary shaft 1, but only a slight creep is allowed until the protruding portion 5 hits the locking protrusion 7 of the bearing housing 3, and the protruding portion 5 is allowed. When 5 abuts on the locking projection 7, creep is regulated and the relative rotation between the bearing side and the bearing housing 3 is substantially eliminated. Therefore, heat generation and wear due to friction with the bearing housing 3 are avoided, and durability is increased.
