Abstract

PROBLEM TO BE SOLVED: To facilitate assembling of a roller even if a holder pillar part is long or if no insertion groove is formed in the inner diameter surface of an outer ring by forming the sectional shape of a pocket between pillar parts such that the roller is pushed into the pocket from the inner diameter side of the holder and falling-off of the roller into the inner diameter of the holder is prevented after the completion of pushing-in. SOLUTION: Falling preventing claws 6 for preventing falling of a roller 3 into the inner diameter side of a holder are provided in both side edges of the inner diameter side of the holder of each pillar part 4b and a space between the opposing falling preventing catches 6 and 6 and the sectional shape of a pocket 5 are formed such that the roller 3 is pushed into the pocket 5 from the inner diameter side of the holder and falling of the roller 3 is prevented after the completion of pushing-in. Each falling preventing catch 6 is provided in the intermediate part of the longitudinal direction of the pillar part 4b and protruded in the inner side of the pocket 5 and the inner diameter side of the holder more than the other parts of the pillar 4b. Thus, the roller 3 is pushed into the pocket 5 from the inner diameter side of the holder 4 and even if the pillar part 4b is long or if no insertion groove is formed in the inner diameter surface of an outer ring 2, the roller 3 is easily assembled in.

ト内にころを押し込み可能な間隔とする。A roller bearing cage according to the present invention is applied to a roller bearing cage which has a plurality of pillar portions extending in a comb-like shape and holds rollers between the pillar portions. To be done. In the cage of this configuration, the cross-sectional shape of the pocket between the pillars is such that the roller can be pushed into the pocket from the cage inner diameter side and the roller does not fall off to the cage inner diameter side when the pushing is completed. It is a thing. It is, so to speak, a comb-type cage that is a roll-in type. According to the cage with this structure, the roller can be pushed in from the inner diameter side of the cage, so the roller can be easily installed even if the cage column is long or if the outer ring inner diameter surface has no groove. You can The cross-sectional shape of the pocket as described above can be realized, for example, by providing a retaining pawl on the side edge of each pillar portion on the inner diameter side of the cage to prevent the rollers from falling off to the inner diameter side of the cage. In this case, the interval between the anti-drop claws facing each other is set so that the rollers can be pushed into the pocket from between these claws.

FIG. 2 shows a cross section of an assembled state of a double-row cylindrical roller bearing with an outer ring collar. This bearing includes an inner ring 1 without a collar, an outer ring 2 with a collar having collars 2a and 2b at the center and both ends, two rows of rollers 3 and 3 interposed between the inner and outer rings 1 and 2, and rollers of both rows. It is composed of one retainer 4 which holds 3,3. The cage 4 has a comb shape and is made of a metal cage cage or a resin molded cage. As shown in FIG. 1, the cage 4 has pillar portions 4b protruding in a comb-like shape on both sides of a central ring-shaped portion 4a, and the rollers 3 in each row are arranged between adjacent pillar portions 4b, 4b. , 3 for holding the pockets 3, 3. The column portions 4b of both rows are alternately projected. In addition, the pillar portions 4b, 4b of both rows
May be provided at the same circumferential position.

チ円を示す。In the cage 4 having this structure, in this example, the retaining pawls 6 for preventing the rollers 3 from falling off to the cage inner diameter side are provided on both side edges of the column 4b on the cage inner diameter side.
There is an interval between the opposing retaining pawls 6 and 6 that allows the roller 3 to be pushed in. As a result, the sectional shape of the pocket 5 is such that the roller 3 can be pushed into the pocket 5 from the inner diameter side of the cage, and the pushing is completed. In this state, the roller 3 is shaped so as not to fall off on the inner diameter side of the cage. The cross-sectional shape of each column portion 4b is a trapezoidal shape in which the inner diameter side of the cage is narrowed, and the retaining claws 6 project from this trapezoidal portion. Both side surfaces of the column portion 4b may be flat or may be arcuate curved surfaces corresponding to the outer diameter of the roller 3. Each stop claw 6
It is provided only on the middle portion of the column portion 4b in the length direction, and projects more toward the inside of the pocket and the inner diameter side of the cage than the other portions of the column portion 4b. In addition, the code PCD in FIG. 1 indicates a pitch circle.

Therefore, the roller 3 can be easily incorporated even when the column portion 4b is long or when the insertion groove is not provided on the inner diameter surface of the outer ring 2. In addition, the cage 4 is less deformed when it is assembled, which improves the operating performance of the bearing.

Can also be used for bearings in which seals 7 are attached to the collars 2a, 2a on both sides of the outer ring 2 as shown in FIG. The bearing in the figure is
It is the same as the example of FIG. 2 except that the seal 7 is provided. The seal 7 may be a contact type made of an elastic body such as rubber or a non-contact type made of metal.
When the seal 7 is provided on the collar 2a of the outer ring 2 as described above, the roller insertion groove cannot be provided on the collar 2a, but even in such a case, the roller 3 is pocketed from the inner diameter side of the cage 3 as described above. Since it can be put in the roller 5, the roller 3 can be easily assembled. Also, when using for multiple rows,
Only one pillar portion 4b with respect to the ring-shaped portion 4a may have the shape shown in FIG.

による効果が大きい。EFFECT OF THE INVENTION The cage for roller bearings of the present invention is a cage cage, but the cross-sectional shape of the pocket between the pillars is such that the rollers can be pushed into the pocket from the cage inner diameter side. Since the roller has a shape that does not fall off to the inner diameter side of the cage when pushed in, it is easy to assemble the roller,
Assembly workability of bearing-using equipment is improved. Further, since the cage is less deformed when the roller is assembled, the operating performance of the bearing is improved. This pocket shape can be achieved by providing, at the side edge of each pillar portion on the inner diameter side of the cage, a stopper claw for preventing the rollers from falling off to the inner diameter side of the cage. Further, by providing the anti-drop claws only in the middle portion in the lengthwise direction of the column portion, it is expected that the rollers will be more easily assembled and the flow of the lubricating oil will be improved depending on the usage conditions. In particular, in the case of cages used for double-row cylindrical roller bearings with outer ring collars, in which the pillars that hold the rollers of each row project on both sides of the ring-shaped portion, or with a seal. In the case of the above bearing, the effect of forming each cage as described above is great.
