る動作不良や破損等の問題が解消される。A cylindrical roller bearing according to the present invention comprises a pair of sheet metal outer ring components having an inward flange on one side edge of a cylindrical portion. An outer ring superimposed on the press-fitted state is provided, and rollers are interposed between the outer ring and the inner ring. According to this configuration, since the outer ring is made of sheet metal, it can be easily manufactured by press working. In addition, since a pair of outer ring components each having a flange on only one side is overlapped and provided with both flanges, the processing is simpler than in the case of pressing a cylindrical body having flanges on both sides, and the manufacturing cost is further increased. Can be reduced. In the above configuration, the inner diameter of the flange of the outer ring is preferably smaller than the outer diameter of the inner ring.
This prevents the outer ring from accidentally coming off the inner ring. Further, when the outer ring components on both sides are press-fitted to each other, the press-fitting depth is naturally determined by the flange hitting the inner ring, and the assembling workability is good. Further, in this configuration, a gap may be provided between the flange of the outer race and the width surface of the inner race to allow axial movement between the inner and outer races. By providing the gap in this manner, the outer ring can move freely in the axial direction, and when the outer ring is used as a roller, it is possible to absorb an error in a rail or the like that the outer ring contacts. Therefore, problems such as malfunction or breakage due to rail errors are eliminated.

In the case of this configuration, the width of the outer ring does not become wider than the width of the inner ring, and the inner ring which is firmly formed by turning or the like can be gripped and handling such as press-fitting of the bearing can be performed. In each of the above configurations, the outer ring component outside the outer ring may be provided with an outer flange that projects outward from an end opposite to the flange. By providing the outer diameter flange in this manner, the rigidity of the outer ring is improved. When this bearing is used as a roller, the outer diameter flange can be used as a width-direction restricting portion for the rail depending on the rail shape and the like. Further, in each of the above configurations, annular ribs along the pitch circle of the roller rows may be provided on the inner surfaces of both flanges of the outer race in a countersink shape. By providing the ribs in this manner, the axial gap of the rollers is reduced, and the axial movement of the rollers is limited, so that stable rotation can be obtained. The ribs also help to improve the rigidity of the flange. In these configurations, the lubricant used in the bearing may be grease, but may be filled with a solid lubricant. The solid lubricant is made of grease containing a polymer or lubricating oil containing a polymer. When such a solid lubricant is used, the lubricant gradually oozes out compared to grease, so that the lubrication life is improved and the lubricant is less likely to leak.

In this cylindrical roller bearing, the outer ring 2 is constituted by a pair of outer ring components 4 and 5, and a roller 3 is interposed between the inner ring 1 and the outer ring 2. Each of the outer ring components 4 and 5 is made of sheet metal having inward flanges 4b and 5b on one side edge of the cylindrical portions 4a and 5a, and the positions of the flanges 4b and 5b are reversed from each other to form the cylindrical portions 4a and 5a. Approximately the entirety is placed in a press-fit state and fixed. The two outer ring components 4 and 5 may have the same plate thickness, but may have different plate thicknesses. When the plate thickness is made different, it is preferable to increase the plate thickness of the outer ring component 5 on the outer diameter side as shown in the figure. The inner diameter of the flanges 4b and 5b is smaller than the outer diameter of the inner ring 1, thereby forming a radial overlapping range L on the inner and outer rings 1 and 2.
Between the width surface of the inner ring 1 and the flanges 4b, 5b of the outer ring 2,
A gap d is provided to allow the inner and outer rings 1 and 2 to move slightly in the axial direction. This gap d does not necessarily have to be provided.

A retainer may be provided depending on the purpose of use. The length of the roller 3 is shorter than the width of the inner ring 1. The inner ring 1 is basically manufactured by turning or cold forging a material and performing soft nitriding, but in some cases, does not perform heat treatment. The outer ring components 4 and 5 of the outer ring 2 are formed by press drawing, and are basically not subjected to heat treatment. Each of the outer ring components 4 and 5 has a practically usable hardness depending on the purpose of use without heat treatment because of the work hardening in the pressing step. If necessary, the outer ring components 4 and 5 are also subjected to heat treatment such as soft nitriding.

作が維持でき、破損の問題が解消される。According to the cylindrical roller bearing having this configuration, the outer race 2
Since it is made of sheet metal, it can be easily manufactured by press working and can be reduced in weight. Moreover, the flange 4b is provided only on each side.
Since the pair of outer ring components 4 and 5 having 5b are overlapped with each other to have both flanges, the shape of each outer ring component 4 and 5 can be obtained only by punching the bottom at the time of deep drawing of a flat plate. Therefore, as compared with the case of pressing a cylindrical body having flanges on both sides, the processing is simpler, and the manufacturing cost can be further reduced. Therefore, an inexpensive and lightweight bearing can be provided as a bearing used for a portion used under a light load or the like or a portion not requiring high precision. The outer ring flanges 4b and 5b whose inner diameter is smaller than the outer diameter of the inner ring 1 play a role of improving rigidity for receiving a radial load, and prevent the outer ring 2 from coming off the inner ring 1. If a gap d is provided between the flanges 4b, 5b and the width surface of the inner ring 1, the outer ring 2 moves to some extent freely in the axial direction. Therefore, when the outer ring 2 is used as a roller, the rail ( (Not shown) can be absorbed, smooth operation can be maintained, and the problem of breakage can be solved.

きる。The inner ring 1 can be press-fitted into a mating shaft, and there is no need for a fixing means such as setting of a retaining ring or a shoulder. When press-fitting the mating shaft, press the flange 4
It is preferable to push the overlapping range L with the inner ring 1 in b and 5b. Thereby, without deforming the outer race 2,
Press fit can be performed. When assembling the bearing, two outer ring components 4 and 5 are press-fitted based on the inner ring width. In this case, since the length of the rollers 3 is shorter than the inner ring width,
There is no danger that the roller end face interferes with the flanges 4b, 5b of the outer race 2 to cause rotation inhibition. Further, since this bearing is a roller bearing, a large bearing load capacity can be obtained as compared with a ball bearing. In addition, since the roller is a full-roller type that does not use a retainer, the number of rollers can be increased, the effect of increasing the load capacity is large, and the manufacturing is simple and the cost is low. Further, during the production, both the inner ring 1 and the outer ring 2 are either eliminated from the heat treatment as described above or are subjected to a simple nitrocarburizing treatment and the polishing step is eliminated, so that the production is further simplified and the cost can be reduced. . The lubricant 6 uses grease or solid lubricant,
Enclosed when assembling the bearing. The grease may be semi-solid or solid. The solid lubricant is composed of, for example, a composition obtained by heating and melting a mixture of a resin such as ultrahigh molecular weight polyethylene or ultrahigh molecular weight polyolefin and grease and solidifying the mixture by cooling. In each of the embodiments described below, grease or solid lubricant can be used in the same manner as described above.

The inner diameter edges of the flanges 4b and 5b are arranged.
The length of the roller 3 is shorter than the width of the large diameter portion accommodated between the outer ring flanges 4b, 5b of the inner ring 1. Other configurations are the same as those in the example of FIG. With such a configuration, the same effects as in the example of FIG. 1 can be obtained. Further, in this example, the bearing can be handled (for example, press-fitting to a mating shaft) by gripping the width surface of the inner ring 1, and the press-made outer ring 2 is less likely to be deformed during handling.

By providing the outer diameter flange 8 in this manner, the rigidity of the outer race 2 is improved. Further, when this bearing is used as a roller, the outer diameter flange 8 can be used as a widthwise restricting portion for the rail depending on the rail shape and the like.
