The present invention relates to an improvement in a cage that is effective as a cage for rollers with a cage so that the rollers do not fall out of cage pockets.

る。(Prior art) Conventionally, the cage is split into two parts, and an appropriate circumferential gap is provided between the split portions (between mutually opposing boundary surfaces), thereby allowing the cage members to move in the circumferential direction. For example, cages that prevent fretting of the raceway surface or that can be commonly used within a specific range even when the raceway diameters of the bearings used are different are: This is known from Japanese Utility Model Application Publication No. 101241/1983.

点でめんどうであり十分とは云えない。(Problems to be solved by the invention) However, in the case of the above-mentioned known cage,
The two retainer members are connected so as not to be separated at least in the axial direction, radial direction, or circumferential direction, and are therefore integrally connected in advance when assembled to the device (shaft). The cage constituent members are separated from each other to form two members, which are then assembled from both sides in the radial direction by sandwiching the shaft between them, which is cumbersome in terms of handling and assembly, and cannot be said to be sufficient.

One of the split parts 4 divided by mutually opposing boundary surfaces has flat surfaces parallel to the axial direction that are symmetrical to each other, and the boundary face of the other divided part, that is, the connecting part side, has a flat surface parallel to the axial direction. As shown in FIG. 2, one cage member 11 has a recess 112 in the center of one boundary surface (end surface side) that penetrates in the radial direction and is recessed in the circumferential direction. The upper and lower walls 113, 114 of the retainer member 12 are constantly engaged with protrusions of the other retainer member 12, which will be described later.
Moreover, in order to prevent the protrusion from slipping out, the protrusion is completely surrounded by semicircular concave grooves 115 and 116 extending in the circumferential direction, and the other member 12 is , has an angular convex portion 121 formed to protrude in the circumferential direction so as to fit into the concave portion 112 with a slight gap on its opposing boundary surface (end surface), and the upper and lower walls 12
2 and 123 have protrusions 124 and 125, respectively, that engage with the grooves to prevent them from separating from each other and guide movement in the circumferential direction within the grooves. A hinge mechanism is formed so as to be able to move in the circumferential direction by a circumferential gap S 3 of the crack on the side that does not have the means.

It is a so-called two crack retainer composed of 1 and 12, and these two members are
There are circumferential gaps S 1 and S 2 in the two cracks as described above.
and are assembled and used by being connected by a connecting means having a specific hinge mechanism that can move in the circumferential direction within the range of the circumferential clearance S3 of the crack 4 which does not have a connecting means. Because it has a structure that
When connecting the two members 11 and 12, the convex portion 12 is inserted into the concave portion 12 by utilizing the elastic deformation of the connecting portion.
1 into the grooves 115, 116 and the protrusion 12.
4 and 125, thereby preventing their separation from each other, and the elbow mechanism of the connecting means is not fixed at a fixed location, but is engaged so that it can move in the circumferential direction. Due to the relative relationship between the circumferential clearances S 1 and S 2 given to the connecting part in advance and the clearance S 3 on the other cracked part 4 side, it is possible to easily move in the circumferential direction, and fretting is effectively prevented. At the same time, the connecting means can be assembled to the shaft with the protrusions 124, 125 serving as fulcrums of the elbows, and the split portion 4 on the opposite side opening fan-shaped in the directions of arrows A and B.
