A pair of a second projection and a corresponding second opening is disposed axially between the first and second pairs of first projections and first openings and fixes the bordering surfaces to each other in a third direction perpendicular to the first and second directions. | 11-21-2013 |
| 20130308891 | ROLLING BEARING - A cage used in a large-size rolling bearing is formed of a plurality of cage segments having a circular-arc shape and arranged in a circular pattern. Each cage segment includes rims opposed to each other and separated from each other at a predetermined interval, and a plurality of cage bars that extend from one of the rims to the other rim and that define pockets which accommodate the rollers and which are arranged in the circumferential direction. Multiple pairs of hook portions, between which the inner ring is sandwiched, are formed so as to project from the rims, and are arranged at predetermined intervals in the circumferential direction. Distal ends of the hook portions are engaged with annular grooves formed in end portions of the inner ring so as be rotatable relative to the inner ring. | 11-21-2013 |

Turning of each of the cage segments is guided by the tapered roller, the cage segments being arranged in a circular pattern along the circumferential direction of the split cage, in an annular space between inner and outer rings. Each cage segment has projections formed so as to project radially inward from the pocket, and formed at the rim portions. A projecting length of each projection is set to such a length that the projection is brought into contact with an outer peripheral side portion of the inner ring before the cage segment is detached from the tapered roller when the cage segment is displaced to the radially inside. | 05-28-2015 |

Turning of each of the cage segments is guided by the tapered roller, the cage segments being arranged in a circular pattern along the circumferential direction of the split cage, in an annular space between an inner ring and an outer ring. A radial clearance between a radially inner portion of a pocket-side face, which is a side face of each of the cage bar portions, and the outer peripheral face of the tapered roller is set larger than an amount of change in the pitch circle radius of the cage segment when the cage segment is displaced radially outward due to thermal expansion. | 05-28-2015 |
| 20150377290 | BEARING WITH K-TYPE CAGE - A K-type cage bearing having two coaxial lateral rings; and a plurality of transverse bars set between the rings and spaced along the circumferential direction, two ends of each transverse bar are respectively connected with the two lateral rings, and two of the bars located adjacent to the opening of the cage are respectively defined as first and second transverse bars. Both the first and second transverse bars are configured with at least one connection element, all the connection elements extend into the opening of the cage, and the connection element on the first transverse bar faces the connection element on the second transverse bar in a one to one manner along the circumferential direction of the cage; one is configured with an inserting block, while the other has a groove. The inserting block is insertable into the groove; and the groove includes first and second side surfaces, the first side surface faces to the transverse bar where the groove is located along the circumferential direction of the cage and is adapted to limit the inserting block from moving along the circumferential direction. The second side surface faces to one of the two lateral rings along an axial direction and limits the inserting block axially so the cage does not tend to loosen at the engaging position of the connection elements. | 12-31-2015 |
