DETERMINING THE TORQUE LOADING OF THE CYCLOID GEAR

Based on experimental investigations, a very close correlation was established between the torque loading of the cycloid gear and the laser sensor's indications measuring the displacement of the gear body. The method is given and the relationship between the registered signal of the torque loading of the gear and the registered laser sensor signal is determined. The practical application of this property in the industrial diagnostics of cycloidal gears is discussed. Spectral analysis of the fast Fourier transform (FFT) signal ripple from a laser sensor is made. These results are compared with the results of the analysis carried out on the ripples of the torques and rotational speeds of the cycloid gear. This comparison shows that the spectral FFT analysis of the ripples of the laser sensor signal is a useful tool in the diagnostics of cycloidal gears.
