Abstract:In all indexes of the accuracy of gears, the measurement of the error of an involute tooth profile is a difficult technical problem. A double-disc instrument for measuring an involute is introduced, the measuring principle of which is the same as the 'rolling artefact method' developed by PTB. In this paper, the measurement error caused by deviation of the measurement point is analysed. In order to increase the position accuracy of the measurement point, a novel method called the 'error compensation method' is introduced, which searches for the best position of the stylus by tentatively compensating the measurement error caused by deviation of the measurement point. According to analysis and experiment, the stylus's adjustment deviation by the 'error compensation method' is 8 mu m.
