摘要: A flat strip of metal is formed to provide a depressed center relief portion between two edge portions. Depressions are formed in the two edge portions and center slots are pierced across the center relief portion such that roller receiving slots are formed with slot end depressions at both ends of the roller receiving slots. The partially formed bearing cage is then formed into a circular hoop such that the edge portions form rings at the axial ends of the circular hoop. The resulting roller bearing cage of the present invention may also be formed by other methods.

摘要: A thrust roller bearing includes rollers arranged in a radial manner, an annular cage that retains the rollers such that the rollers are rollable, an annular outer race located on one side of the cage in an axial direction of the cage and having a first raceway on which the rollers roll, and an annular inner race located on the other side of the cage in the axial direction and having a second raceway on which the rollers roll. At least one of the first raceway and the second raceway has a Vickers hardness that is greater than or equal to 800 and less than or equal to 950. The outer circumferential surface of each of the rollers has a Vickers hardness that is greater than or equal to 697 and less than 800.

摘要: A thrust roller bearing cage (11) is a cage (11) provided to a thrust roller bearing and having a plurality of pockets (21) that house needle rollers (13). The cage (11) includes projections (44) that are formed by bending a radially outer area of the cage (11) inwardly along the radius and that project inwardly along the radius toward a radially outer area of the pockets (21) to make contact with end faces (16) of the rollers (13). The projections (44) have corners (45) that make contact with the end faces (16) of the rollers (13). The corners (45) are press-flattened.

摘要: A cage for a radial bearing assembly with rolling elements is provided. The cage includes a first and second rims, and webs extend between the rims to define pockets that receive rolling elements. Each of the webs includes first and second rolling element guide surfaces that face a first adjacent one of the pockets and third and fourth guide surfaces that face a second adjacent one of the pockets. These guide surfaces are located at a pitch circle adapted to coincide with a centerline of the rolling elements located in the pockets. The webs have first and second radially inner retention tabs that respectively face the first and second adjacent ones of the pockets. The first retention tab is located axially between the first and second guide surfaces and the second retention tab is located axially between the third and fourth guide surfaces. The retention tabs are located radially inside the pitch circle.

摘要: A thrust roller bearing cage (11) of the present invention is included in a thrust roller bearing (20) and includes a plurality of pockets (21) accommodating rollers (13). The thrust roller bearing cage (11) includes: a first cylindrical portion (36) extending in a direction of a rotation axis (12); a first disc portion (31) continuous with the first cylindrical portion (36) and extending in a radially outward direction; and a second cylindrical portion (37) continuous with the first disc portion (31) and extending in the direction of the rotation axis (12). The first cylindrical portion (36), the first disc portion (31), and the second cylindrical portion (37) are formed in an area located radially inside the pockets (21). The first disc portion (31) has a through hole (53).

摘要: A thrust roller bearing cage (11) of the present invention is included in a thrust roller bearing (20) and includes a plurality of pockets (21) accommodating rollers (13). The thrust roller bearing cage (11) includes: a radially outer area bent portion (41) formed by bending an area located radially outside the pockets (21) inward in a radial direction; and projecting portions (44) that are formed in a tip end of the radially outer area bent portion (41) at positions aligned with the pockets (21) and project inward in the radial direction beyond radially outer edges of the pockets (21) so as to contact end faces (16) of the rollers (13) accommodated in the pockets (21). The projecting portions (44) have a width that is ⅓ or more and ⅔ or less of the width of the pockets (21).

摘要: A needle roller and cage assembly include a cage having a width larger than a diameter thereof. Pillar sections of the cage each include roller retaining portions on radially inner and outer sides with respect to a roller pitch circle diameter and an oblique portion through which the roller retaining portions are continuous with each other. The oblique portion includes a first relief portion formed therein, for avoiding interference with a needle roller. The adjacent pillar sections form a pocket having a rectangular shape therebetween. The pocket includes a second relief portion in each of four corners thereof. The second relief portion extends in the axial direction of the cage from a position at which a short side of the pocket is elongated in a circumferential direction of the cage to an outer end of the roller retaining portion on the radially outer side.

摘要: A method for producing a holder in which sagging is suppressed in a bent part to be formed into a flange portion, without using bulge forming and a split mold that restrains the inside of a working target article; and a holder. An upper punch presses and bends one end portion of a working target article inward, whereby a flange portion is formed in the one end portion. A smaller-diameter portion of the working target article is restrained from the inside and outside by a lower punch and split mold portions. Then, a peripheral surface portion of a convex portion of the upper punch receives the end portion of the working target article and applies an outward pressure to the end portion. A bent part is pushed toward a larger-diameter portion restraining part of a split die, so that sagging is prevented from occurring in the bent part.
