The paper presents the results of deviations and accuracy manufacturing measurement of selected geometric parameters of pinions and gears made for the same nominal dimensions and the same accuracy class. The measurement was made on the coordinate measuring machine from Klingelnberg GmbH, which is commonly used, among others, to assess the accuracy of gears manufactured for air transport vehicles. Selected parameters of the tested pinions and gears were measured and analyzed, which have a significant impact on the emission of vibrations and noise of the operating gearbox. Vibroactivity of gearboxes in case of many means of transport is a very important research topic because vibrations and noise generated by drive systems of various means of transport affect passengers and are the source of environmental noise pollution. The analysis of the obtained results showed that despite adopting the same nominal dimensions and the same accuracy class, the tested gears are characterized by significant (often strong and exceeding the range of the adopted accuracy class) variability of specific, selected geometric parameters. The use of gears, even those made in the same precision class, in the case of gearboxes used in means of transport, whose quiet operation is an important operational aspect, should be extended by accurate measurement of selected geometric parameters.
