[Abstract]:Arc bevel gear is widely used in aviation, automobile and other industries because of its stable transmission, low noise and high bearing capacity. The main transmission modes are intersection or mismatch, and the performance of the gear directly affects the performance of the transmission system. With the development of modern industry, the requirements for spiral bevel gears, such as automobiles, construction machinery and helicopters, are becoming more and more high, especially in the aspects of bearing capacity and transmission error. Focusing on the meshing characteristics of spiral bevel gears, this paper focuses on the bearing capacity and contact trace of gears. The parametric design and 3D modeling are realized by studying the forming principle and meshing theory of spiral bevel gear, and the parameterized modeling software is obtained, and the methods of gear contact analysis and bearing contact analysis are analyzed. In this paper, the Hertz contact theory and contact algorithm are summarized, and the contact algorithm in ANSYS is discussed. In ANSYS workbench, the tooth bearing contact of arc bevel gear is studied and analyzed, and the contact trace of arc bevel gear is obtained, and the results of tooth bearing contact analysis of arc bevel gear are analyzed. Based on the analysis of tooth profile modification theory, the maximum modification quantity, modification length and profile curve of tooth profile modification are established, and the solid geometric model of modified arc bevel gear is established, and the load bearing contact analysis of modified gear is carried out. The results show that the contact track has been improved effectively and the contact strength has been greatly improved after modification, which provides an effective theoretical basis for the research and practice of tooth profile modification of spiral bevel gear.
