ROLLER BEARING CAGE, ASSEMBLY AND PRODUCTION METHOD THEREFOR, AND ROLLER BEARING
First Claim
1. A roller bearing cage having a ring shape for retaining an interval along a circumferential direction between a plurality of rolling elements in a roller bearing, said roller bearing cage comprising:
- a plurality of bar-shaped members which are arranged along the circumferential direction and which restrain movement of the rolling elements along the circumferential direction;
a plurality of connecting members, each of which connects end portions along a lengthwise direction of the bar-shaped members adjacent to each other along the circumferential direction; and
a fixing structure which fixes the bar-shaped member and the connecting member so as to be relatively unrotatably around an axis line along the lengthwise direction of the bar-shaped member.

Abstract
A roller bearing cage according to one aspect of the invention is a cage having a ring shape for retaining an interval along a circumferential direction between a plurality of rolling elements in a roller bearing. The roller bearing cage includes: a plurality of bar-shaped members which are arranged along the circumferential direction and which restrain movement of the rolling elements along the circumferential direction; a plurality of connecting members, each of which connects end portions along a lengthwise direction of the bar-shaped members adjacent to each other along the circumferential direction; and a fixing structure which fixes the bar-shaped member and the connecting member so as to be relatively unrotatably around an axis line along the lengthwise direction of the bar-shaped member.

2. A roller bearing cage having a ring shape for retaining an interval along a circumferential direction between tapered rollers corresponding to a plurality of rolling elements used in a tapered roller bearing as a roller bearing, said roller bearing cage comprising:
-
a plurality of bar-shaped members which are arranged along the circumferential direction and which restrain movement of the rolling elements along the circumferential direction; and a plurality of connecting members, each of which connects end portions along a lengthwise direction of the bar-shaped members adjacent to each other along the circumferential direction, wherein the plurality of bar-shaped members are disposed such that axial centers along the lengthwise direction of the plurality of bar-shaped members cross one another at one point on an axial center of the roller bearing, and wherein the connecting members are bent in an arc shape with a radius of curvature about the one point. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11)

12. A split cage for a roller bearing, comprising:
-
a plurality of first segments made of a synthetic resin and a plurality of second segments made of a synthetic resin, the first segments and the second segments being arranged in a ring shape along a circumferential direction, wherein each of the plurality of first segments comprises; a rim portion positioned on a first side along an axial direction; a pair of pillar portions which protrude from the rim portion toward a second side along the axial direction opposite to the first side along the axial direction, and which are respectively disposed between rolling elements of the roller bearing; and a pair of engaging portions provided on the second side along the axial direction of the pair of pillar portions, wherein each of the plurality of second segments comprises; a first engaged portion to be engaged with the engaging portion provided on the pillar portion disposed on a first side along the circumferential direction of the first segment; and a second engaged portion to be engaged with the engaging portion provided on the pillar portion disposed on a second side along the circumferential direction opposite to the first side along the circumferential direction of another one of the first segments adjacent, on the first side along the circumferential direction, to the first segment, and wherein the pair of engaging portions are engaged with the pair of engaged portions, whereby the plurality of first segments are connected in a ring shape by the plurality of second segments. - View Dependent Claims (13, 14, 15, 16, 17)
