It is known from 86249. A rigid retainer, which is essentially cylindrical, comprises closed roller pockets. The web flanks have a concave guide surface which extends in a uniform shape over the entire axial length of the web and which fits into the rollers. Thus, particularly good guidance and lubrication of the rollers is provided. In order to insert the rollers easily and without damage to the surface in roller pockets which also provide radial confinement, the side surfaces are provided with circumferentially extending grooves. In this case, the two ribs that serve as holding protrusions that prevent the rollers from falling
They are arranged apart from each other in the axial direction. When the rollers are fitted, the ribs elastically slightly deviate in the circumferential direction. This measure further reduces weight.

られると言うことが、製造時に判った。In the case of this type of cage, there is a clear difference between the role of the guide surface during operation and the retaining function during bearing assembly. That is, the known solution of dividing the role of the retainer into a guiding function and a retaining function can be further improved and the weight can be further reduced.
Actually turned out. Furthermore, milling of roller pockets,
It has been found during manufacturing that burrs remaining after broaching or eccentric turning prevent the insertion of rollers, especially in automated mass production processes.

It is to create a policy to do.

The holding projections are formed on both sides of the groove slopes outwardly in the axial direction, the groove slopes are inclined outward in the axial direction, and are arranged so as to move to the bottom surface of the groove in the region of the web.

る。Although it is preferable to provide grooves that are continuous in the axial direction, it is basically possible to machine a plurality of grooves that are closely arranged. By this measure, a retaining projection is formed at the end of the web or roller, while the guiding area is reduced radially by the groove. The action of the retaining projections at the ends of the rollers is geometrically optimal. Because, thus,
This is because the cage is optimally stabilized. It has been found that guide surfaces which are reduced by the grooves or which are displaced in the radial direction are practically suitable or at least not disadvantageous.
The sloping groove bevels form a continuous transition from the web to the side ring, i.e. increase the stability at said transition and prevent undesired notch action under heavy load.

ろの端面転動時の潤滑が促進される。The groove profile is formed, for example, by a bottom surface which extends over most of the web and two inclined groove slopes which follow said bottom surface. In this case, the groove slope reaches the side ring region where the groove slope transitions to the outer surface of the side ring. The groove slope is machined in the region of the pocket, for example, to the extent that a chamfer occurs in the side ring after the groove has been machined. In this case, the edge between the pocket surface provided on the side ring and the outer peripheral surface of the side ring is chamfered at the above-mentioned location. Thus, burrs that occur during pocketing are reduced, avoided, or eliminated by the grooving process. Further, the inclined chamfered portion promotes lubrication during rolling of the end surface of the roller.

構成された溝斜面を有する。According to another feature of the invention, the groove provided in the insertion opening adjacent to the side ring is in the region of the side ring, is inclined axially outwards and is extended in the circumferential direction. In the region of the pocket, it has a grooved bevel configured as a chamfer of the side ring.

る。In this case, the inclined groove bevels are further machined in the region of the side rings, so that stronger chamfers or wider chamfers result. The chamfered portion serves to facilitate the insertion of the roller when the roller is introduced in the roller pocket with some inclination or axial displacement. In addition, the above-mentioned advantages regarding burrs and lubrication are obtained.

に移行し、共通の加工曲線上を半径方向へ延びる。The holding surface of the protrusions is simultaneously or uniformly machined by a common machining process of the side surface of the web by milling, turning or the like. The holding surface and the guide surface thus transition with each other and extend radially on a common machining curve.

することができる。EXAMPLES The cage shown in FIGS. 1-3 is essentially cylindrical in shape and was made from brass by cutting. The cage consists of two concentric left and right side rings 1,1 and a plurality of axial webs 2 joining the two rings in a circumferentially spaced manner, in pockets formed at adjacent intervals of the web 2. The cylindrical roller 3 is inserted. On the inner peripheral surface 4 of the cage, there are three annular inner peripheral grooves 6 with a narrow groove width, which are turned in the center and to the left and right, and on the outer peripheral surface 5, there is an annular outer peripheral groove 7 with a wide groove width. The inner circumference has two inner holding projections 8, 8 on the left and right of the central annular groove 6, and the outer circumference has two outer holding projections 9 on the left and right of the annular groove 7. The facing surfaces of the adjacent webs 2 are formed in a concave shape, and each has a guide surface 10 continuous in the axial direction for guiding the operating cylindrical roller 3, and strong holding surfaces on the inside and outside of the holding projections 8 and 9. It is divided into 11 and. Guide surface 10 and holding surface 1 for all protrusions 8 and 9
1 shifts to the common radial machining curve 12.
As shown in FIG. 3, the machining curve 12 can be formed not by a single circular arc, but by curved portions having different curvatures that transition with each other.

よって、ころ3の端部が安定化される。The bottom surface 17 of the outer peripheral groove 7 extends over the entire length of the substantially web 2 in the axial direction, and the left and right ends of the left and right groove slopes 13 inclined outward in the radial direction and the axial direction have left and right sides. A part of the outer circumference of the partial ring 1 is chamfered to finish.
Thus, two left and right outer retaining projections 9 acting on the end of the cylindrical roller 3 are created, and in the region of the pocket the inclined groove slope 13 is circumferentially extended to form a chamfer 15. The transition from the groove slope 13 to the groove bottom 17 takes place in the region of the web 2. The outer retaining surface 11 also terminates at this point and transitions to a guide surface 10 optimized for lubrication between the cylindrical roller 3 and the cage. The left and right holding projections 9 stabilize the ends of the rollers 3.

2の弾性によって円周方向へそれる。The inner peripheral surface 4 is formed with three inner peripheral grooves 6, so that the web 2 has two inner holding protrusions 8 axially separated from each other. Also in this case, each inner circumferential groove 6 is provided with the groove slope 14 which is inclined in the radial direction and the axial direction.
The axially outer groove slopes 14 of the two axially outer left and right inner circumferential grooves 6 deviate from the region of the web 2 and form a relatively large chamfered portion 16 which chamfers the side rings 1, 1. The chamfer 16 serves to align the cylindrical roller 3 during insertion. The cylindrical roller 3 is tilted and its edge is chamfered 1
Fig. 1 shows a state in which the No. 6 is fitted into the pocket by a chain line. The cylindrical roller 3 is fitted in the pocket by pressure in the radial direction. As a result, the inner holding projection 8 is deflected in the circumferential direction by the elasticity of the web 2.

作用を防ぎ寿命を延長できる。As described above, according to the present invention, the weight can be made lighter and more compact than the conventional retainer of the same kind, and burr is prevented from being generated when the pocket is pressed. In addition, since the inner peripheral surface of the side ring is also chamfered, it is easy to insert the rollers, and the notch action is prevented even under a heavy load to extend the life.
