摘要:
A needle bearing (11), comprising an outer ring (13) having a plurality of outer ring members (12) divided by a parting line extending in the axial direction of the bearing, a plurality of needle rollers (14) rollingly disposed on the raceway surface of the outer ring (13), and a retainer (15) holding the intervals of the needle rollers (14). Each of the outer ring members (12) comprises a projection (12a) as a positioning engagement part for positioning the outer ring (13) on a housing at a position displaced from the circumferential center part of its outer peripheral surface and an engagement claw (12b) projecting from the axial end part of the outer ring member (12) to the radial inner side to restrict the axial movement of the retainer (15).

A needle roller bearing (21) as a roller bearing comprises an outer ring (22) formed by connecting a plurality of arc-shaped outer ring members in a circumferential direction, and a plurality of needle rollers (23) arranged along the inner diameter surface of the outer ring (22), and an oil groove (22i) extending in a circumferential direction so as to contain a position opposed to an opening (13e) of an oil path of a housing is formed in the outer diameter surface of the outer ring member.
摘要:
A needle roller bearing comprises an outer ring having a plurality of outer ring members split by split lines extending in an axial direction of the bearing, a plurality of needle rollers arranged on an orbit surface of said outer ring so that they can roll thereon, and a cage holding the needle rollers at intervals. The outer ring member has a projection serving as a positioning engaging part which engages with a housing for positioning, and an engaging click protruding from an axial end of the outer ring member inward along a diameter to prevent the cage from moving in an axial direction, in positions shifted from its circumferential center.

A needle roller bearing (21) as a roller bearing comprises an outer ring (22) having a plurality of outer ring members (22a) and (22b) split by a split line extending in the axial direction of the bearing, and a plurality of needle rollers (23) arranged along the track surface of the outer ring (22). The outer ring member (22a) is in the form of a semicircular shape having a center angle of 180° and has an engagement click (22c) bent from one circumferential side end to the radial outer side. The two outer ring members (22a) and (22b) are connected in the circumferential direction to form the annular outer ring (22).
摘要:
A rocking bearing outer ring (12) includes an arcuate track member (13) having a track surface on its inner diameter surface, and a flange portion (14) projecting radially inward from each widthwise end portion of the track member (13). In addition, when it is assumed that Li represents a circumferential length of the track member (13) and L 2 represents a circumferential length of the flange portion (14), 0.2 ≤ L 2 /L 1 ≤ 0.8 is satisfied.

摘要:
A roller bearing (21) includes a plurality of needle rollers (23), a cage (24) that retains the rollers (23), and an outer ring (22) that has a rolling surface on which the rollers roll and is split in the circumferential direction. The cage (24) includes split sections (32a), (32b) at which the cage can be split in the circumferential direction. The cage (24) is of a roller riding type or an inner land riding type.
