    摘要： The invention concerns a rolling bearing with a rolling bearing cage (1) having a plurality of rolling element pockets (2) arranged in at least one row to receive at least one row of rolling elements, wherein the rolling bearing cage (1) consists of two lateral rings (3) and a plurality of crosspieces (4) connecting them, between which crosspieces are formed the rolling element pockets (2), and having at least one empty pocket (5). In order to achieve cost-effective manufacture of the rolling bearing cage (1) with the fewest possible changes as compared to a rolling bearing cage fully populated with rolling elements, provision is made according to the invention that the rolling bearing cage (1) is equipped with fewer rolling elements in one row than corresponds to the number of rolling element pockets (2), causing the rolling bearing cage (1) to have empty pockets (5) without rolling elements in the at least one row of rolling element pockets (2). The empty pockets (5) can be implemented in a simple manner by omitting one or more rolling elements, so that storage spaces for lubricant are created. Furthermore, the empty pockets (5) can be formed by targeted shaping in such a manner that a conveying or pumping action is produced in at least one direction of rotation. The invention also concerns a method for producing such a rolling bearing cage.

    摘要： The invention concerns a rolling element cage (32) made of a metal strip material that is profiled, stamped, cut to length, and bent into a round shape, wherein the ends of the cut-to-length strip sections are joined together by welding. In order to make it possible to influence the lubricant distribution in the bearing and the vibration characteristics of the cage and thus of the overall bearing system, according to the invention the strip section ends (34, 36) are joined together with a predetermined axial offset (a) and/or radial offset (b).

    摘要： A ring-shaped metal rolling bearing cage, which has cage pockets for receiving rolling elements. The cage is formed by a first and a second cage segment. Adjoining ends of the cage segments are connected to one another by suitable connection assemblies. At least one of the assemblies permits a change of the cage diameter when the cage temperature changes. The suitable assembly, on one side, is configured as a joint mechanism and, on another side, as a locking mechanism, and at least one of the assemblies has a lash. A rolling bearing cage configured with the joint mechanism and the locking mechanism can be mounted with low time expenditure in a simple and reliable manner over a shaft, particularly in the case of an idler pinion mourning.

    摘要： A needle sleeve, in particular for pivotably mounting the throttle valve shaft of a control device for recirculating exhaust gas in internal combustion engines. The needle sleeve provides a thin-walled outer ring formed without cutting. A needle roller and cage assembly is inserted in the outer ring. The needle cage carries the bearing needles at uniform spacings in the circumferential direction. The needle sleeve has, at its axial sides, two radially inward facing ribs holding the needle roller and cage assembly in the outer ring and has multiple seals that seal the sleeve to prevent exhaust gas condensates from flowing through. The outer ring of the needle sleeve is a rimless, cylindrical sleeve, and the seals are two lip sealing rings having an S-shaped cross-sectional profile. The seals are located at least partially outside the outer ring and are pressed onto its axial edges, and provide the radially inward facing ribs.

    摘要： The invention concerns a needle sleeve (1), in particular for pivotably mounting the throttle valve shaft of a control device for recirculating exhaust gas in internal combustion engines, which consists primarily of a thin-walled outer ring (2) formed by non-cutting means and a needle roller and cage assembly (3) that is inserted in this outer ring (2) and is composed of a plurality of bearing needles (4) and a needle cage (5) that carries the bearing needles (4) at uniform spacings in the circumferential direction. The needle sleeve (1) has, at its axial sides, two radially inward facing ribs (6, 7) holding the needle roller and cage assembly (3) in the outer ring (2), and is designed with multiple seals (8, 9) by means of which the sleeve is sealed to prevent exhaust gas condensates from flowing through. According to the invention, the outer ring (2) of the needle sleeve (1) is designed as a rimless, cylindrical sleeve, while the seals (8, 9) of the needle sleeve (1) are composed of two lip sealing rings with an S-shaped cross-sectional profile that are located at least partially outside the outer ring (2) and are pressed onto its axial edges (10, 11), which sealing rings are at the same time implemented as radially inward facing ribs (6, 7) of the needle sleeve (1) that retain the needle roller and cage assembly (3) in the outer ring (2), and by means of which sealing rings the needle sleeve (1) can be sealed both statically to a housing enclosing it and dynamically to prevent exhaust gas condensates from flowing through.
