Abstract:

A Fourier series method has been developed, by means of which the dynamic responses of gear systems can be obtained. This method simplifies the calculations considerably, and retains the whole and parametric properties in processing complicated gear systems, gives the solutions of systems in time and frequency domain at the same time. A dynamic eeperiment of helical gearing was carried out, the accelerations of relative vibration and trans-miting errors of this system were measured. The comparison of computation with experiment has proved the accuracy and the availability of the Fourier method.

Key words: helical gear, vibration, transmiting error
