Before the gear fails, the vibration is caused by the stiffness of the gear itself. Therefore, the gear is not the same as the failure of the gear during the normal running state, and the noise and vibration of the gear can be well distinguished when the fault occurs again. Therefore, it is possible to judge whether or not a malfunction has occurred from the vibration frequency at which the gear is generated. The signal characteristics of the gears when the gears fail during the running-in process can be divided into time domain features and frequency domain features.
During the normal running-in of the gear, the time-domain frequency of the gear is a periodic sinusoidal waveform. The frequency domain characteristics of normal operation are reflected in the power both the tooth frequency and the higher harmonics, but the main feature of the tooth flatness is that the high harmonics of the automobile lubricating oil are also regular high. The harmonics are reduced in turn.
The gears occur in the event of failure in the running-in process and in the case of lubricating oil and long-term high loads, so their time domain characteristics and frequency domain characteristics are different from those in normal times. In the time domain feature, the sinusoidal frequency and the toothing frequency are broken due to the breakage of the teeth, and the low frequency is heard, so that a harsh sound is heard.
In the frequency domain feature, the high frequency harmonics increase, and when the wear is quite serious, an irregular jump of the high frequency harmonics occurs.
