摘要: A bearing raceway element configured as an inner ring or as an outer ring, or configured to be attachable to an element serving as an inner ring or as an outer ring for the bearing or to an inner ring or an outer ring of the bearing. The raceway element is manufactured from a sheet metal panel and includes at least one first joint edge and at least one second joint edge directed in the circumferential direction that are configured to be connected to each other in order to form an annular raceway element. The at least one first joint edge is at least partially configured as a first alignment element and/or includes the first alignment element. Also a bearing including the raceway element and an associated method.

摘要: A sheet-metal bearing cage segment has a first ring section, at least one second ring section and a plurality of bridges connecting the first ring section and the at least one second ring section to each other such that a pocket for receiving at least one rolling element is formed between each circumferentially adjacent pair of the bridges. The first and/or second ring section includes at least one recess on the radially inner side and/or the radially outer side.

摘要: A bearing cage segment of a sheet metal cage includes first and second sheet metal ring sections and bridges therebetween defining a plurality of pockets for receiving rolling elements. A first circumferential joint edge of the segment is configured to connect to a second circumferential joint edge of the segment or to a second joint edge of another segment, and the first joint edge includes at least one alignment element, such as a projection or contour, that is configured to align the first joint edge radially, axially and/or circumferentially against the second joint edge which may include a complementary alignment element such as a recess or complementary contour.

摘要: A sheet metal bearing cage segment includes a first sheet metal ring section, at least one second sheet metal ring section, and a plurality of bridges connecting the first ring section and the at least one second ring section to each other, adjacent pairs of the bridges forming pockets configured to receive at least one rolling element. At least one edge of the first ring section and/or at least one edge of the at least one second ring section and/or of one of the bridges is at least partially formed by laser cutting. Also a method of forming a sheet metal bearing cage at least partially by laser cutting.

摘要: A sheet metal bearing cage segment includes first and second ring sections, bridges connecting the ring sections to form pockets for rolling elements and a circumferentially facing joint edge configured to be connected to another circumferentially facing joint edge. The joint edge is disposed such that it will be located in one of the bridges after the joint edge is connected to the another circumferentially facing joint edge.

摘要: A raceway element for a rolling-element bearing, the rolling-element bearing having an inner ring, an outer ring, and a plurality of rolling elements that are disposed between the inner ring and the outer ring. The raceway element is configured as an inner ring or as an outer ring, or is configured to be attachable to an inner ring or outer ring of the bearing, wherein at least one surface of the raceway element is configured as a raceway for the rolling elements. The raceway element is formed from a sheet metal panel having at least one recess formed in the surface configured as the raceway.

摘要: A sheet metal bearing cage segment includes a first ring section, at least one second ring section, and a plurality of bridges connecting the first and second ring sections to each other and defining a plurality of pockets between the bridges. The bearing cage segment includes first and second circumferentially directed joint edges, the first joint edge is configured to connect to the second joint edge of the bearing cage segment or to a second joint edge of another sheet metal bearing cage segment, and the first joint edge includes at least one body of welding material projecting from the joint edge. The body of welding material may be pressed against the second joint edge while leaving a gap between the joint edges, and the welding material can be liquified by a resistance welding process to connect the joint edges.
