Abstract

Based on the counting method for clock pulse subdivision which measures the gear transmission error, the torsional vibration model of the gear transmission error test platform has been established to solve the problem that the measurement accuracy is susceptible to resonance when the natural frequency of the measurement system of gear transmission error is identical to that of the excitation frequency. In this study, the natural frequency of the transmission system was calculated and verified by the sweep frequency test. By analyzing the sweep frequency response curve of the direct connecting shaft and gear pair, the transmission components were weakened so that the test speed of transmission error could fall into the non-resonant flat interval between the first-order and second-order natural frequency. The optimal speed range of the tested gear pair was tested by scanning frequency. The measurement results not only avoid interference frequency but also possess good repeatability, providing a reliable and accurate measurement technology for vibration and noise reduction of gear minor modification.
