Abstract
A rolling element guide cage having a ring element which is made from a sheet material and has an axial profiling produced using forming techniques and forms a plurality of successive rolling element guide structures in the circumferential direction. The ring element is composed of at least two flat material ring segments joined to one another successively in the circumferential direction, said segments being joined together in a manufacturing step which precedes the formation of the axial profiling.
Claims9
A rolling body guide cage comprising a ring element which is produced from a sheet metal material and has a formed axial profiling and several rolling body guide structures which are arranged in succession in a circumferential direction, wherein the ring element is comprised of at least two flat material ring segments which are joined to one another in succession in the circumferential direction by connections prior to formation of the axial profiling, and the flat material ring segments are connected to one another in a region of engagement zones across positively engaging joint contours.
A rolling body guide cage comprising a ring element which is produced from a sheet metal material and has a formed axial profiling and several rolling body guide structures which are arranged in succession in a circumferential direction, wherein the ring element is comprised of at least two flat material ring segments which are joined to one another in succession in the circumferential direction by connections prior to formation of the axial profiling, wherein the rolling body guide cage is embodied as a radial bearing cage and is comprised of a first one of the ring elements and a structurally identical second one of the ring elements positioned in mirror-symmetry.
A method for manufacturing a rolling body guide cage from a ring element which is produced from a sheet metal material, comprising forming an axial profiling in a forming step including several rolling body guide structures arranged in succession in a circumferential direction and in a method step which precedes the forming step, forming the ring element of at least two flat material ring segments by joining the flat material ring segments to one another in succession in the circumferential direction, with the flat material ring segments being connected to one another in a region of a joint formed by the flat material ring segments, and connecting the flat material ring segments to one another in a region of engagement zones across positively engaging joint contours.
