  • Publication number: 20220241880
    Abstract: A method for producing a tooth geometry includes selecting a root-side starting contour configured as an ellipse segment and a head-side partial contour of a tooth; selecting an adaptation region for at least a part of the root-side starting contour; determining for the adaptation region a correction specification determined using a correction function configured as an at least third-order polynomial having at least one adjustable function parameter comprising adjustable coefficients; modifying the root-side starting contour using the correction specification to form a root-side final contour, and producing the tooth geometry by chip-removing machining based on the head-side partial contour and the root-side final contour. Also disclosed are a computer program product for carrying out the method, a tool for manufacturing the tooth geometry based on the method, and a machine component having the tooth geometry.

  • Patent number: 6902219
    Abstract: An actuating arrangement and method for opening and closing a hinged motor vehicle panel utilizes a controllable fluid drive and an uncontrolled fluid drive. The hinged motor vehicle panel is driven during opening from a starting position to a predetermined opening angle by the controlled fluid drive and, after reaching the predetermined angle of opening, is driven into its final position exclusively by the uncontrolled fluid drive.

  • Patent number: 6533342
    Abstract: An actuating arrangement for opening and closing a hinged motor vehicle panel has a fluid drive, a control unit, and a sensor unit. The hinged motor vehicle panel is movable between a starting position and an end position, and the control unit evaluates start signals from the sensor unit and stopping the movement of the motor vehicle panel in an intermediate position. The start signals from the sensor unit correspond to current angles of opening of the hinged motor vehicle panel, and predetermined angles of opening of the hinged motor vehicle panel define certain criteria. It is possible to set at least the angle of opening of the intermediate position via the control unit.
