  • Quiet gear wheel and method for producing such a gear wheel
    Patent number: 10890241
    Abstract: The present invention relates to a gear wheel containing at least one sintered material having a porosity, the gear wheel having, in addition to the porosity, another noise-reducing means.
    Type: Grant
    Filed: February 1, 2016
    Date of Patent: January 12, 2021
    Assignee: GKN Sinter Metals Engineering GmbH
    Inventors: Björn Leupold, Simon Höges, Markus Schneider, Thomas Schupp, Vitali Janzen, Gerhard A. Kotthoff, Eberhard Ernst
  • Method and device for producing a gear together with a clamping means
    Patent number: 10363598
    Abstract: The invention relates to a method for producing at least one gear, in particular a helically toothed gear, wherein the gear is produced from a gear blank pressed and sintered with an oversize in the region of the set of teeth, wherein the gear blank has two opposite end faces and a circumference. In the method, the gear blank is clamped in a clamping means. The gear blank is compressed in the region of the oversize by means of the engagement of at least one circumferential tool having a set of mating teeth that engages with the set of teeth of the gear blank, wherein the gear blank is radially clamped over the circumference by the clamping means at both end faces during the compression of the gear blank, wherein each individual tooth of the set of teeth of the gear blank is supported by the clamping means substantially over the entire tooth height. In this way, the quality of the set of teeth can be improved. The invention further relates to a device and to a clamping means.
