A low noise level is an important quality feature in moderngearboxes for passenger cars. But a troublesome noise can have manycauses. The noise origination and transmission is amongst othersaffected by the design layout, by the actual deviations of thecomponents, by the assembly of the components and also by themounting situation of the complete gearbox. Damages, form errorsand displacement errors or ripples are often present on the flanksof a gear, if it is found to be the cause of problems in a noisecheck. Especially ripples or ‘ghost frequencies’ of a gear areproblematic, because up to now they rarely can be detected on agear measuring device but only in a relative complex single­flankroll checking procedure. A new evaluation method now allows toidentify and to describe ripples on the flanks of gears based onthe results of a normal gear measurement. The deviation curves wereapproximated by sine functions, the results are displayed graphicaland by characteristic values. A combination of the deviation ofeach measured point with its rotation angle allows an evaluationequal to a rolling with the mating gear. The results show a verygood correlation to a noise check and to a single­flank roll check.The application of the software is demonstrated by practicalexamples of the manufacturing methods generating grinding, honing,broaching and shaving. Vibrations of machine tool and ripplegenerating influences in the manufacturing process can be verifieddown to a level of a few tenth micrometers. At the same time thismethod is well suited to describe long­wave form deviations like anovality or a 3­ or 4­fold ripple caused by the clamping or by asquare blank. With this new evaluation method gears can be testedin an early state of production for known, critical ripples andconclusions can be drawn on the state of machine tool, cutting tooland clamping device.
