Abstract

As a key component in mechanical transmission, straight-toothed bevel gears can realize commutation in the transmission process, withstand strong load capacity, which can meet the demand for efficient and stable transmission in engineering applications, so the study of its working characteristics has important engineering significance. The aim of this study is to analyze the static and contact modal analysis of the straight-toothed bevel gear pair by the finite element method to ensure the safety in the actual working process. Firstly, an accurate geometrical model of the straight bevel gear pair was established and meshed using finite element software. In the static analysis, the stress distribution and deformation of the gear pair under different loading conditions are considered. The strength of the gear pair was evaluated by applying different boundary conditions and loads. The contact modal analysis focuses on the influence of tooth contact characteristics on the dynamic response of the gear. The contact modes of the gear pair under actual working conditions are simulated, and the variation of the vibration pattern during its operation is analyzed and the corresponding frequency diagrams at different orders are listed, and it is found that the meshing frequency is lower than the hazardous frequency, and no danger will occur.
