  • Patent number: 10022798
    Abstract: A method forms a crowning on a sintered component made from a sintering powder, in particular on the teeth of a sintered component including a toothing. The sintered component is calibrated in that the sintered component is introduced into a calibration tool. The sintered component includes a forming chamber with at least one forming wall. In the forming wall a crowning is formed which is inverse to the crowning of the sintered component to be formed. After calibration the sintered component is removed again from the calibration tool. The size of the forming chamber of the calibration tool remains unchanged at least for the time period beginning with the insertion of the sintered component into the calibration tool and ending after the removal of the sintered molding from the calibration tool.

  • Publication number: 20160214178
    Abstract: The invention relates to a method for forming a crowning on a sintered component (2) made from a sintering powder, in particular on the teeth of a sintered component (2) comprising a toothing, by calibrating the sintered component (2), for which reason the sintered component (2) is introduced into a calibration tool (1), which comprises a forming chamber (8) with at least one forming wall (9), wherein in the forming wall (9) a crowning is formed which is inverse to the crowning of the sintered component (2) to be formed and after calibration is removed again from the calibration tool (1). The size of the forming chamber (9) of the calibration tool (1) remains unchanged at least for the time period beginning with the insertion of the sintered component (2) into the calibration tool and ending after the removal of the sintered molding (2) from the calibration tool (1).

  • Patent number: 7810625
    Abstract: A sintered clutch ring (1) is described, comprising a rim of clutch teeth (2) which comprise wedge-like face surfaces (3, 4) intersecting in an axial plane and flanks (5) sloping downwardly under an angle of inclination from the tooth back (6) against the tooth root, with the flanks (5) being relieved starting from a re-entrant, axially normal shoulder (7). In order to provide advantageous conditions for press forming the flank reliefs it is proposed that the planes of intersection between the wedge-like face surfaces (3, 4) extend outside of the center of the teeth and that the mutually axially offset shoulders (7) of the two flanks (5) of the clutch teeth (2) separate the relieved flanks (5) from a paraxial flank portion (8) which is substantially triangular and is adjacent to the face surfaces (3, 4).
