摘要:
Present invention relates to provide a cage suited in particular to a supersized roller bearing, which is easy to improve rigidity, realizes a reduction in manufacturing costs, facilitates dimension management and accuracy management, and is less prone to progress abrasion of end surfaces of rollers. A roller bearing cage (1A) is configured such that a pair of ring parts (4, 6) axially separated from each other is connected by column parts (5) sliding on outer peripheral surfaces of rollers (RA), and pocket holes (P) are evenly formed to store and hold the rollers (RA) in a peripheral wall portion in a circumferential direction. The cage (1A) is manufactured such that a base body (2) including the ring part (4) and the column parts (5) with square columnar convexes (5A) and a connection body (3) including the ring part (6) with square holes (6A) are set as separate members.

The embodiments herein relate to a bearing component (100) comprising a first cage cup (101) formed from at least one first element configured to receive rolling elements (305). The bearing component (100) further comprises a first flange (107) formed from at least one second element and connected to a periphery of the first cage cup (101).

The invention relates to a rolling element bearing, especially a roller/needle bearing comprising a cage having at least one inner cage and at least one outer supporting cage that comprise windows (3) adapted to the rolling elements (8), with edges (4) connecting a plurality of windows (3), and cross struts, in which the rolling elements (8) are guided and secured from falling out. According to the invention, either the inner cage and the supporting cage are embodied as a slotted inner cage ring and/or a slotted supporting cage ring that can be fixed to each other on the ends, or the inner cage and the supporting cage are embodied as inner cage shells and/or supporting cage shells that can be fixed to each other on the ends.

The invention relates to a radial antifriction bearing (1) which substantially consists of an outer bearing ring (2) and of an inner bearing ring (3) as well as of a multitude of rollers (4), arranged between the bearing rings (2, 3) and held by a bearing cage (5). The rollers (4) are configured in the form of spherical disks that each have two parallel lateral surfaces (8, 9) which are symmetrically flattened from a basic spherical shape. The bearing cage (5) according to the invention is characterized by having cage pockets (15) in which the rollers (4) are axially guided between the bearing rings (2, 3) via two low-friction point contacts between the center areas (16, 17) of their lateral surfaces (8, 9) and the longitudinal webs (18, 19) of the cage pockets (15). The rollers are configured to have a defined degree of freedom for tilt movements exerted at an angle to the running direction and a defined degree of freedom for self-adjustment to the pressure angle of the radial antifriction bearing (1).

The invention relates to a cage for rolling bodies of a rolling bearing, comprising a first side ring (8), a second side ring axially spaced from the first side ring, and at least two webs (1), which connect the first side ring (1) to the second side ring and among each other form a pocket for one of the rolling bodies, wherein at least one of the webs (1) comprises a first web part (3) disposed at the first side ring (8) and a second web part (4) disposed at the second side ring, and a center web part (5) offset with respect to the first and second web parts (3, 4). The object of configuring the above cage such that it can withstand greater mechanical stresses is achieved according to the invention in that a support element (6) is provided, which supports the first web part (3) and the second web part (4) and connects the two side rings (8).
摘要:
A combined roller and retainer assembly for a planetary gear mechanism, including a planetary gear and a support shaft for supporting the planetary gear, includes a roller retainer (1) and a plurality of rollers (2) and is adapted to be interposed between the planetary gear and the support shaft for supporting the planetary gear and the support shaft through the rollers (2). The roller retainer (1) includes a pair of annular portions (103, 104) spaced in an axial direction from each other and a plurality of pillars (105) extending between respective outer peripheral edges of the annular portions (103, 104) and spaced in a direction circumferentially of the annular portions (103, 104). The rollers (2) are accommodated within respective pockets (106) each defined between the neighboring pillars (105). One or both of the annular portions (103, 104) are provided with roller retaining pawls (107) of a bent shape in respective portions of inner peripheral portions of the annular portions (103, 104) at a location aligned with the neighboring rollers (2) for constraining the rollers (2) from separating in a direction radially inwardly of the roller retainer (1). The roller retaining pawls (107) are annealed or treated not to be carburized to have a hardness about equal to or lower than the hardness of the roller retainer (1) and equal to or lower than Hv 400.
