Abstract
The reduction of the vibration and noise of gears is an important issue in mechanical devices such as vehicles and wind turbines. The characteristics of the vibration and noise of gears are markedly affected by deviations of the tooth flank form of micrometer order; therefore, strict quality control of the tooth flank form is required. The gear measuring instrument is generally calibrated by an involute helicoid artefact. In the tooth flank form measurement of the involute helicoid artefact, the setting error of the involute helicoid artefact largely affects the measurement result. The laborious setting operation is required for the calibration of the gear measuring instrument. Therefore frequent calibration of the gear measuring instrument has not been realized. In this study, evaluation method of the gear measuring instrument using multiple-tooth involute helicoid artifact is proposed to reduce the effect of the setting error. The efficiency of this method is confirmed by the measurement simulation using a computer program.
