摘要: A method for manufacturing at least one synchronizing ring includes providing a rough-turned blank made from a hardenable material that is in a not-hardened state and laser-cutting the rough-turned blank to form the at least one synchronizing ring, the laser cutting being performed with an energy chosen to be sufficient to selectively harden at least a portion of the material in a region along which the laser cutting occurs.

摘要: A sheet metal strip configured for use as an inner or outer raceway of a rolling-element bearing, and a method of forming the raceway by punching and/or laser cutting a strip of material from a metal sheet, bending the sheet into a ring and welding the ends of the strip together, and mounting the strip on a circular inner or outer surface to form an outer or inner raceway.

摘要: A raceway element for a rolling-element bearing having an inner ring, an outer ring, and a plurality of rolling elements disposed between the inner ring and the outer ring, the raceway element being configured as the inner ring of the bearing or as the outer ring of the bearing, or being configured to be attachable to an inner ring or outer ring of the bearing. 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, and the raceway element includes a flange for guiding the rolling elements formed one-piece with the raceway element. Also, a bearing including the element and a method of forming the element.

摘要: A method of forming a bearing cage segment includes determining a path of a periphery of the bearing cage segment along a metal sheet, punching a plurality of openings in the metal sheet inside the path to form a plurality of pockets separated by a plurality of bridges and separating the bearing cage segment from the metal sheet at the path. The separating includes laser cutting first and second joint edges at a first end of the row and third and fourth joint edges at a second end of the row, where the first joint edge is spaced from the second joint edge in a length direction of the bridges and the third joint edge is spaced from the fourth joint edge in the length direction of the bridges.

摘要: A method of forming a bearing cage segment includes punching a plurality of openings in a sheet metal band to form a plurality of pockets separated by a plurality of bridges, the bridges having a length direction transverse to a length direction of the band and having a width in the length direction of the band and having a thickness in a direction perpendicular the length direction and to the width, and laser cutting the sheet metal band along one of the plurality of bridges transversely to the length direction of the band to form a joint edge.

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.

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 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 and forming pockets for receiving at least one rolling element. The first ring section and/or the at least one second ring section includes a circumferentially facing joint edge configured to be connected to another circumferentially facing joint edge to form a to-be-formed pocket. The joint is spaced from the plurality of bridges, and the joint edge is formed by laser cutting. The joint edge may include a chamfer on a radially outer side and/or on a radially inner side.
