On the one hand, based on the test results presented in Section 6.3, the basic mechanism of noise generation and on the other hand the influence of gear oil on gear rattling is explained. This is where the analysis of the relative angle of the rolling gear pair presented in Section 6.1 comes into play for use. In all of the following test series, an oil sump temperature of 80 ℃ and an excitation frequency of 30 Hz (nm = 900 rpm with four-cylinder engine simulation) is used.
