Description of the Related Art In an automobile transmission, a tapered roller bearing 21 is generally used for supporting an output shaft and an input shaft as shown in FIG. The inner ring 22 of the tapered roller bearing 21 is attached to the shaft end small diameter portion 23a of the shaft 23 in a press-fitted state. The outer ring 24 is attached to the tubular portion 25a of the housing 25 with a loose fit, and the width surface of the outer ring 24 is fixed to the housing 25.

かる。Since the housing 25 is made of an aluminum alloy as described above, the coefficient of linear expansion is as large as about three times that of the shaft 23 made of a steel material. Therefore, when the temperature changes due to the operation, the dimensional change amount of the housing 25 becomes larger than the dimensional change amount of the shaft 23, and it becomes impossible to maintain an appropriate preload of the bearing 21 which is initially set. As a solution to such problems,
Attempts have been made to provide an annular notch groove at the side edge on the thick wall side of the outer diameter surface of the outer ring, and insert an elastic body such as a resin member or a spring member into this groove. However, in that case, the number of parts increases, and it takes a lot of time and labor to handle the assembly into the housing.

It is a spring piece. "Integrally formed" here does not mean that a separate part is attached to the outer ring,
The outer ring is made of the same material as the other parts of the outer ring by cutting or molding. The spring piece may be, for example, a ring-shaped leaf spring formed between the width surface and a circumferential groove provided on the outer diameter surface of the outer ring near the thick side width surface of the outer ring. The outer ring width surface portion that is the side surface of the one piece is an inclined surface that gradually projects in the width direction as it approaches the outer diameter side.

一定の予圧量を得ることができる。This tapered roller bearing is fitted to the inner diameter surface of the housing in a state where the thick side width surface of the outer ring is engaged with the axial locking surface of the housing. The engagement causes the spring piece of the outer ring to be pressed against the locking surface of the housing. As a result, the spring piece is bent and the bearing is in the preloaded state. When the temperature rises during operation, an axial gap tends to be generated between the bearing outer ring and the locking surface of the housing due to the difference in linear expansion coefficient between the housing and the shaft. However, the spring piece expands in the width direction of the bearing by the elastic restoring force by the gap, and the pressure contact state with the locking surface of the housing is maintained. Therefore, preload release due to thermal expansion of the housing is prevented. When the spring piece is a leaf spring formed by a circumferential groove on the outer diameter surface of the outer ring, and the side surface of the spring piece is the inclined surface, when mounting the bearing, the inner diameter side portion of the thick side width surface of the outer ring Is pressed until it engages with the locking surface of the housing, the spring piece bends by a certain amount,
A constant amount of preload can be obtained.

The tapered roller bearing 1 includes a tapered roller 5 held by a cage 4 between an inner ring 2 with a collar and an outer ring 3 without a collar.
It is of the type that intervenes. In this structure, the outer diameter side portion of the portion forming the thick side width surface 3b of the outer ring 3 is the spring piece 6 integrally formed with the outer ring 3. This spring piece 6 has an outer diameter surface 3a of the outer ring 3 near the thick side width surface 3b.
A ring-shaped leaf spring is formed between the circumferential groove 7 and the width surface 3b. The outer ring width surface portion 3b 1 formed of the side surface of the spring piece 6 is an inclined surface that gradually protrudes in the width direction as it approaches the outer diameter side, and the inner diameter side width surface portion 3b 2 of the width surface 3b is a predetermined protrusion amount h at the outer diameter end. Make it more prominent. Therefore, the spring piece 6 has a cross section in which the outer diameter side gradually becomes thicker. Further, in the annular groove formed on the width surface 3b,
A constricted portion 6a is provided on the base end portion of the spring piece 6 so as to be easily bent. The material of the inner and outer rings 2, 3 and the roller 5 is bearing steel or the like. Although the outer ring 3 is made of the same material as a whole, one or both of the spring piece 6 and the root portion thereof may be heat-treated so as to obtain an appropriate spring rigidity.

る。This tapered roller bearing 1 is shown in FIG.
As shown by the chain line in (B), the inner ring 2 is fixed to the shaft end small diameter portion 8a of the shaft 8 in the automobile transmission in a press-fitted state. The outer ring 3 is attached to the inner diameter surface portion 9a formed by the tubular portion of the housing 9 by loose fitting, and the thick side width surface 3b of the outer ring 3 is engaged with the axial locking surface 9b of the housing 9. This engagement is such that the inner diameter side width surface portion 3b 2 of the outer ring 3 is in contact with the locking surface 9b. As a result, the spring piece 6 of the outer ring 3 is pushed by the locking surface 9b and elastically bent, and a predetermined amount of preload is applied to the bearing 1 by the elastic restoring force. The housing 9 is made of aluminum alloy. In this type of transmission, the shaft 8 is supported at both ends by a pair of tapered roller bearings as in the conventional example, and the tapered roller bearing 1 of this embodiment is used for at least one of the bearings.

による予圧抜けが防止される。The operation of the above configuration will be described. At room temperature, the bearing outer ring 3 is in contact with the locking surface 9b of the housing 9 as described above. When the temperature of the transmission rises during operation, the difference in linear expansion coefficient between the aluminum alloy housing 9 and the steel shaft 8 causes the inner diameter side width surface portion 3b 2 of the outer ring 3 and the locking surface 9b of the housing 9 to be separated from each other. There is an axial gap between them. However, the bending of the spring piece 6 is restored by the elastic force by the amount of the gap, and the pressure contact state with the locking surface 9b of the housing 9 is maintained. Therefore, preload release due to thermal expansion of the housing 9 is prevented.

1の固定が行われる。By absorbing the axial gap by the spring piece 6 as described above, the initially set proper preload can be maintained in a wide temperature range. Also, the spring piece 6
Since it is formed integrally with the outer ring 3, the number of parts is reduced compared to the case where a separate elastic member or the like is provided, and the handling such as assembling into the housing 9 is the same as that of a conventional general bearing. Easy to do. Moreover, the inner diameter side portion 3b 2 of the thick side width surface 3b of the outer ring 3 is engaged with the locking surface 9 of the housing 9.
A constant amount of preload can be obtained simply by pressing until it engages with b, and it is easy to set the amount of preload. Further, in this embodiment, since the spring piece 6 has a shape in which the outer diameter side gradually protrudes in the width direction, in the state of being attached to the housing 9, in general, substantially the entire outer ring width surface 3b is engaged with the locking surface 9b. . Therefore, the bearing 1 is stably fixed without being locally contacted.

Further, as shown in FIG. 3A, the spring piece 26 may be a ring-shaped leaf spring extending from the outer diameter portion of the outer ring 3 toward the inner diameter side by processing the groove 27 in the width surface 3b.
