Description of the Related Art As an axle bearing device for a railway vehicle, a grease-filled or oil-bath lubricated type is used in order to bear a radial load and an axial load and to extend a maintenance interval for lubrication and cooling. Double row tapered roller bearings are often employed. In FIG.
One example of a conventional grease-filled double-row tapered roller bearing is shown by a half longitudinal section. The tapered roller bearing 1 has a spacer 3
, A pair of inner and outer rings 7 which are fitted to the axle 5 via the shaft, an outer ring 13 which is fitted to the bearing housing 11, the inner rings 7 and the outer ring 1
3 and a pair of inner and outer retainers 17 for holding the tapered rollers 15. The inner ring 7 has a small-diameter end side and a large-diameter end side with roller locking flanges 19 and 21, respectively, and a dust seat 23 externally fitted to the boss side of the axle 5, and an end portion of the axle 5. It is disposed between the dust seat 25 fitted on the outside and integrated with the axle 5 by a bearing fixing lid 29 fastened to the end of the axle 5.

に組み付けることができなくなる。In the above-mentioned conventional tapered roller bearing, the crimping process is required to stabilize the crimping state because the crimping process is required at the time of assembling the cage. There was a problem. In manufacturing the retainer 17, first, a steel plate or the like is drawn into a conical shape as shown in FIG. 5, and a pocket 41 into which the tapered roller 15 is fitted is punched and formed as shown in FIG. As shown in (1), the column portion 43 is plastically worked into a shape corresponding to the tapered rollers 15. The cage 17 is completed by the plastic working shown in FIG. 7. In this state, when the tapered roller 15 is fitted into the pocket 41 from the inside of the cage 17, the minimum inscribed circle diameter of the tapered roller 15 is smaller than that of the inner ring 7. Since the outer diameter of the end roller locking flange 19 is smaller than the outer diameter, the tapered roller 15 and the retainer 17
Can not be assembled.

5. The minimum inscribed circle diameter of the inner ring 7 is a small diameter end side roller locking flange 19 of the inner ring 7.
The small-diameter end side of the retainer 17 is once expanded by using the bottom pushing punch 45 so as to be larger than the outer diameter of the holder 17. This allows
The tapered rollers 15 and the retainer 17 can be assembled to the inner ring 7, but if they are kept, the inner ring 7, the tapered rollers 15 and the retainer 17 are separated after assembly. Therefore, FIG.
As shown in (2), in order to restore the shape of the retainer 17 incorporated in the inner race 7, the small-diameter end side of the retainer 17 is crimped using the crimping tool 47.

I couldn't. As a result, skew easily occurs between the tapered roller 15 and each pocket 41,
Unusual heat is generated in the tapered roller bearing 1 or the cage 1
It is necessary to perform the crimping process management by multiplying the man-hour so that the operating life of 7 etc. is not significantly affected.

A tapered roller bearing comprising: an outer ring fitted inside a bearing housing; a plurality of tapered rollers interposed between the inner ring and the outer ring; and a retainer provided for holding these tapered rollers. It is proposed that the roller locking flange on the small diameter end side is a flange ring which is externally fitted to the inner ring.

FIG. 1 shows a tapered roller bearing according to a first embodiment of the present invention in a half longitudinal section. The tapered roller bearing 1 of the present embodiment is for a grease-filled double-row type railway vehicle, and has a pair of inner and outer inner rings 7 externally fitted to an axle 5 via a spacer 3 and an outer ring internally fitted to a bearing housing 11. 13
And two rows of tapered rollers 15 interposed between the inner ring 7 and the outer ring 13, and a pair of inner and outer retainers 17 for holding the tapered rollers 15. The inner ring 7 has a roller locking flange 21 on the large-diameter end side, and a dust seat 23 externally fitted on the boss side of the axle 5 and a dust shield externally fitted on the end side of the axle 5. Seat 2

れる。In the tapered roller bearing 1 of the first embodiment, a small-diameter stepped portion 51 is formed on the small-diameter end sides of both inner races 7, and a flanged ring made of steel pipe, which is a roller locking flange, is formed on the small-diameter stepped portion 51. 5
3 is fitted with a predetermined interference. Therefore,
As shown in FIG. 2, when the tapered roller 15 and the retainer 17 are assembled to the inner ring 7, the minimum inscribed circle diameter of the tapered roller 15 is significantly larger than the small-diameter end side outer diameter of the inner ring 7. The tapered roller 15 can be inserted from the small diameter end side without resistance, and then the flanged ring 53 is press-fitted or shrink-fitted to the small-diameter stepped portion 51 of the inner ring 7 using a hydraulic device, a heating device, or the like. 15 is completely prevented from falling off.

An outer ring fitted inside a bearing housing, a plurality of tapered rollers interposed between the inner ring and the outer ring, and a tapered roller bearing including a retainer provided for holding these tapered rollers, Since the small-diameter end-side roller locking flange is a flange ring that is fitted to the inner ring, for example, after the tapered rollers and the retainer are assembled to the inner ring, the small-diameter end-side roller locking flange is pressed into the inner ring. By fixing to the cage, the process of expanding the small-diameter end side of the cage and the caulking after assembling become unnecessary, and the shape and dimensional accuracy of the cage can be easily increased, resulting in skew. Abnormal heat generation in tapered roller bearings and operation of cage, etc. Reduction and bearing stable quality of man-hours by the abolition of the caulking management for preventing deterioration of life was obtained.
