摘要： A diameter dimension of a chamfer 11 which is formed on axial end faces of a cylindrical roller 8 which is retained in each pocket 7 of a cage 2 whose axial positioning is realized by a roller guide at a portion which lies closer to an outside diameter side thereof is made such that a central flat surface 9 which lies on an inside diameter side of the chamfer 11 is not exposed from an external surface of an outside diameter side flat plate portion 14. Then, a difference between a minimum value ΔB of an amount by which the cylindrical roller 8 projects from the external surface of the outside diameter side flat plate portion 14 and a dimension W11 of the chamfer 11 with respect to a diameter direction thereof is made smaller than a thickness T2 of the cage 2.

摘要： The invention relates to a cage (1) for rolling bodies (6), in particular a needle cage, consisting of two side rings (2, 3) spaced apart from one another in the axial direction and having end faces, the side rings (2, 3) being connected, to form pockets (5) receiving rolling bodies (6), to transverse webs (4) spaced apart from one another uniformly in the circumferential direction.The cage (1) is distinguished in that the end faces at least partially follow a course which deviates at an angle of inclination (α) of 90° with respect to a bearing axis (9).This ensures a particularly effective lubrication between the end faces of the cage (1) and the connecting structure, this lubrication being important particularly in the case of bearings subjected to high loads.

摘要： A rotary machine may include an inner component and a first group of cylindrical rollers disposed around the inner component. Each of the cylindrical rollers may have end-faces. The rotary machine may further include an outer component with a first cylindrical inner surface disposed against the cylindrical rollers. Additionally, the rotary machine may include a first bearing cage associated with the first group of cylindrical rollers. At least a portion of the first bearing cage may be disposed inside the first cylindrical inner surface, and the first bearing cage and the first cylindrical inner surface may be associated with one another in such a manner to maintain the first bearing cage substantially concentric to the first cylindrical inner surface. The rotary machine may also include a first axial stop configured to limit axial movement between the outer component and one or more of the cylindrical rollers. Additionally, the rotary machine may include a second axial stop configured to limit axial movement between one or more of the cylindrical rollers and a component of the rotary machine other than the outer component.

摘要： In the present cage, both pillar portions which face each other in a circumferential direction of a pocket have a plurality of bent portions which are alternately bent in a width direction, and each bent portion is provided with roller stopping portions protruding into the pocket. The bent portions are formed in a curved cross-sectional shape. Tip portions of the bent portions in the thickness direction of the cage are formed in a cross-sectional shape that becomes narrower toward the tips, and the tip portions are drawn in a state where they protrude into the pocket by plastic deformation working, thereby forming the roller stopping portions.

摘要： A thrust roller bearing includes a race and a cage that retains a plurality of rollers and is disposed on the race. The race includes: an annular plate portion defining a raceway for the plurality of rollers, a flange that is extended in an axial direction thereof and provided at a radially outer side or a radially inner side of the annular plate portion, and an annular locking portion that is provided at an entire periphery on a front end of the flange and is projected in a radial direction thereof in such a manner that the annular locking portion catches a radially outer side or a radially inner side of the cage in the axial direction. Only the annular plate portion is softer than the annular plate portion.

摘要： In thrust needle bearings 16A and 16B, radial needle bearings 15A and 15B, and a shaft 14, each part is treated to have a nitrogen concentration of 0.3 weight % or more, and a Vickers hardness of Hv=653 to 832. Therefore, abrasion of the contacting portions is minimal, and it is possible to suppress premature abrasion, and extend the life, even if used under severe lubrication conditions.

摘要： In a cage for cylindrical rolling bearings (5), which cage is rolled out of a sheet metal strip (12), the pockets (4), as seen in a top view, have, in a profiled, punched and unbent state of the sheet metal strip (12), a curved shape in a region of the inclined sections (8, 9), so that an axially inner, first convex curve B1 merges into an outer, second concave curve B2. This pocket contour of the invention makes it possible to obtain a separation between the retention of the rolling elements and the contact region of the rolling elements in the cage solely by the punching of the pockets in combination with a subsequent bending of the cage strip into a finished cage.
