In this invention, a retainer for holding rolling elements of a rolling bearing is constituted by a large number of block-shaped holding members forming pockets for holding the rolling elements,
The present invention relates to a retainer in which the holding members are connected in an annular manner using an annular elastic body to form one retainer, thereby providing flexibility to the retainer and absorbing vibrations of a bearing.
The details of the present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 shows an example of a holding member 1 according to the present invention, and the holding member 1 shown in this figure has a machined Bakelite cage in pockets 2, 2...
It is obtained by cutting in the axial direction from the center of the machined cage, that is, the center line of the machined cage,
Concave grooves 3 are provided on both sides thereof. As shown in FIGS. 2a and 2b, the holding members 1 are arranged in an annular manner such that the cut surfaces of each holding member 1 face the cut surfaces of the adjacent holding members 1. Next, by bonding or embedding annular rubber plates 4 into grooves 3 formed on both sides of each holding member 1, each holding member 1 is flexibly connected to form a flexible retainer 5. . FIG. 3 shows that by cutting a Bakelite machined cage in the middle between adjacent pockets 2,
This shows an example in which a holding member 1 is formed. The holding member 1 shown in this figure is also similar to the one described above, and has grooves 3 on both sides that fit into the annular rubber plate 4. By fitting the rubber plate 4 into the groove 3, the holding member 1 shown in FIG. A flexible retainer is constructed in the same way as in the previous example. In the above two embodiments, the holding member 1 was obtained by cutting a Bakelite machined cage, but this holding member 1 was obtained by injection molding made of synthetic resin such as polyacetal or nylon. They may also be formed individually. Further, in order to provide rigidity to the flexible retainer 5 obtained by connecting the holding members 1, the thickness of the rubber plate 4 may be increased or a slightly harder rubber plate 4 may be used. As described above, the flexible retainer 5 according to the present invention is constructed by connecting a large number of block-shaped holding members 1 having pockets 2 for holding rolling elements 6 in an annular manner with an annular rubber plate 4.
Since the flexible retainer 5 is formed, the retainer can be made flexible, and vibrations generated during rotation of the bearing can be absorbed in the gaps between the blocks of the flexible retainer 5.
