Vibration Diagnosis and Case Analysis of Gear Faults
The obvious impact peak appears in the time-domain waveform, indicating that there may be local defects in the gear. The spectrum shows the gear meshing frequency and double harmonic frequency, with rich edge frequencies. From Figure 3, it can be seen that the edge frequency is the rotor power frequency, indicating that the vibration amplitude of the meshing frequency is modulated by the rotor power frequency impact vibration.

Carburization Quenching Process and Deformation Analysis of Bevel Gears
The material of the bevel gear is SNC815 carburized steel, and its chemical composition is shown in Table 1. The parameters of the bevel gear used for analysis are shown in Table 2. Considering computational efficiency and economy, the workpiece was simplified during the analysis. One tooth of the bevel gear was simulated and the contact surface between the tooth and the other teeth was used as the symmetry surface. When dividing a single tooth model into tetrahedral grids, set the number of grids to 60000.
