Including A Master Patents (Class 33/501.16)
  • Patent number: 7775101
    Abstract: A universal dynamic gear quality and consistency verification inspection system and method is provided. The system and method provides a dynamic gear verification inspection station including a Double Flank master gear and a probe for inspecting gear features and an electronic plug having pre-reference pads and mechanical rests for supporting and locating the part to be inspected. The probes are provided to verify all angles and functional parameters relayed to appropriate software for evaluation and record maintenance. A probe may also be provided for face checking.

  • Patent number: 7020972
    Abstract: The invention concerns a process for the aligning of the tooth spaces of workpieces (1) with precut teeth, which are set up for fine machining on the work spindle (2) of a gear finishing machine. In order to avoid the trend related occurrence of out-of-tolerance aligning errors as series production progresses, teach-in cycles are performed on the workpiece machined in the immediately preceding machining cycle, called for automatically after time intervals or machining cycle intervals which are either pre-defined or calculated by the machine control system. By this means any prevailing trend errors are restored to zero.

  • Patent number: 6874241
    Abstract: Measuring means for determining measurement error factors of a measuring machine, which measures toothing tolerances of gearwheels by inserting two gauging balls in different tooth gaps of a gearwheel and then taking measurements from the positions of the inserted balls, comprises a reference master having two first helically extending grooves disposed on an external or internal circumference of the master and representing tooth gaps receiving the two gauging balls to permit simulated measurements applicable to an externally or internally helically toothed gearwheel with an even number of teeth and two second helically extending grooves disposed on the same circumference as the first grooves and representing tooth gaps for respectively receiving the two balls to permit simulated measurements applicable to an externally or internally helically toothed gearwheel with an uneven number of teeth.
