The setting of the tool can be corrected by means of these deviations via a control loop.

Abstract: A method and device for measuring an amount of wear on a flank of a gear tooth is provided. The method includes positioning a template comprising a first template tooth adjacent a gear comprising a first gear tooth. The method also includes adjusting the position of the template in a rotational direction with respect to a known rotational reference point of the gear, adjusting the position of the template in an axial direction with respect to a known axial reference point of the gear, and adjusting the position of the template in a radial direction with respect to a known radial reference point of the gear. The method further includes measuring an extent of a gap between an edge of the first template tooth and an adjacent flank of the first gear tooth, wherein the gap corresponds to the amount of wear on the flank.

Abstract: A measurement tool for determining a position of a pinion gear in a differential assembly includes a mounting member configured to contact an end face of the pinion gear and an elongated arm member extending outwardly from the mounting member. The arm member has an arm portion configured to overlie one of the bearing seats of the differential assembly and an aperture formed in the arm member configured to receive a measurement gage therethrough. The measurement gage is used to measure a distance between a surface of the bearing seat and a reference surface of the arm member from which the position or “pinion depth” of pinion gear can be determined.

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.

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.

Abstract: A method and apparatus for determining a pinion bearing move to correct pinion-to-gear alignment based on pinion &Dgr; t overcoming the aforementioned drawbacks are provided. Using a realistic visual representation of a gear to pinion mesh showing pressure angles of the gear and pinion as well as the angle of the pinion down from the mill center line allows for a quick and accurate determination of a pinion bearing to align a pinion-to-gear assembly move. Using temperature differential data of the pinion under load conditions, the present invention allows for an easy and efficient means of determining a pinion bearing move to align a pinion-to-gear assembly without requiring complicated manual calculations or data input to a computer program. Furthermore, the present invention is lightweight and portable thereby avoiding the drawbacks often associated with handheld electrical devices and laptop computers.

Abstract: A device and method for gear checking measurement of a gear employs a pair of measuring pins or balls of predetermined outer diameter which are placed in tooth spaces on diametrically opposite sides. The measuring pins or balls are held in the tooth spaces by a holding element which is fixedly connecting to and spaced from each measuring pin or ball in a direction along the gear axis so that an accurate measurement can be taken of the overall external diameter over the measuring pins. In one version, the holding element is a separate magnet or pair of magnets coupled to a respective measuring pin or ball. In another version, a holder frame holds a pair of measuring pins or balls at circumferential positions with a pre-counting spacing of gear teeth on diametrically opposite sides of the gear.
