3D Modeling And Geometric Parameters Design Of Logarithmic Spiral Bevel Gear

With the rapid development of China's industrial, bevel gear in the machinery, automobile, aviation and other industries more and more widely applied, and the machinery and equipment to the large, heavy-duty, high-speed development, the smooth gear drive, and the carrying capacity of a high degree of coincidence large, long life, high reliability requirements are much too high, there is an urgent need to increase the bevel gear transmission performance and efficiency to meet the needs of engineering. Logarithmic spiral with a spiral line in the same helix angle of the point features all the same, with the excellent engineering properties, so as a spiral bevel gear tooth to the line in order to solve the spiral bevel gear drive existing different mesh point is not equal to the helix angle brought about by the low efficiency of power transmission, friction and wear serious, such as transmission is not smooth shortcomings. Research bevel gear transmission is a breakthrough in the field of research is the area of bevel gear transmission of the inheritance and development of scientific research with a larger study of the meaning and value of great works.In this paper, the research work completed include the following:1. By the completion of the study to have been a number of spiral bevel gear meshing theory and analysis of transmission characteristics, combined with Gleason spiral bevel gear design, in-depth study of the novel and the Gleason spiral bevel gears spiral bevel gear the similarities and differences of principle from the mesh, have been a number of spiral bevel gears of the structure.2. Through the logarithm of the three-dimensional spiral bevel gear design, verification of the number of spiral bevel gear meshing system correctness and feasibility of gear for the next phase of the finite element analysis, simulation and other agencies provided the necessary conditions for follow-up CNC machining, manufacturing, laid the foundation for a number of spiral bevel gear design parameters provided the basis for determination.3. In the number of spiral bevel gears based on the three-dimensional shape, contrast Gleason spiral bevel gear design of the round billet to study a variety of gear system recommended by the empirical formula, line maps and empirical data, analysis of the number of spiral bevel gear determine the parameters of the design and the principle of the gear is given the definition of the various geometric parameters and the basic parameters determining the method of laying the foundation for the project.
