Patent number: 8256594Abstract: A freewheel cage, which has a basic body with two annular, substantially radially extending edge disks that are connected to one another by a plurality of axially running connecting pieces and at least one annular component for fastening the basic body to a freewheel. The connecting pieces are adjacent to one another in the circumferential direction so as to form intermediate spaces for at least partially holding clamp bodies. The annular component is formed as a separate component arranged on at least one of the edge disks. By design, the basic body for the freewheel cage is produced with reduced expenditure, and subsequently, the annular component for fastening the basic body to a freewheel can, as a separate component, be produced, and arranged on the basic body for fastening to a freewheel with likewise correspondingly reduced expenditure.Type: GrantFiled: August 14, 2009Date of Patent: September 4, 2012Assignee: Schaeffler Technologies AG & Co.

Publication number: 20090285518Abstract: The invention relates to an axial rolling bearing having a cage which contains rolling bodies that are arranged between two running disks. The running disks each have a radial section that forms a raceway and an axially aligned collar which adjoins the raceway. The collars are aligned opposite to one another and overlap in the axial direction. The radially outer disk has a larger diameter than the radially inner running disk. According to the invention, the radial and the axial extent of the two collars of the running disks and the cage are coordinated with one another in such a way that, between them, a labyrinth seal, composed of a plurality of gaps, is formed, and the cage is guided on the collar of the radially inner running disk.Type: ApplicationFiled: June 1, 2007Publication date: November 19, 2009Applicant: SCHAEFFLER KGInventors: Wolfgang Fugel, Stefanie Gumbmann, Andreas Kirschner, Sebastian Kroener, Alexander Reimchen
