Equal-high Spiral Bevel Gear are important transmission parts in mechanical equipment.Due to their high meshing quality,stable transmission,and strong carrying capacity,they are increasingly used in aerospace,engineering machinery,transportation and other industry.Because equal-high spiral bevel gears are very complex to machine and adjust,meanwhile deformation of machining tools,assembly errors,and machine parameter settings will affect the accuracy of the machined gears,and it is not easy to obtain high-quality machining surfaces.Therefore,based on the analysis of the machining principle of equal-high spiral bevel gear,the simulation of equal-high spiral bevel gear is optimized,and the cutting parameters are optimized.The main research contents of the paper are as follows:First of all,by analyzing the meshing principle of gears and applying coordinate transformation methods,the meshing equations of equal-high spiral bevel gear are established;the machining process of equal-high spiral bevel gear is analyzed,and the cutting surface equation of the milling cutter disc is derived.The main parameters of the milling cutter structure are analyzed,and the structure of the milling cutter head is optimized.Secondly,use finite element software to simulate the real machining process.Through single-factor simulation,analyze the effect of cutting parameter changes on the cutting force and cutting temperature during the machining process;analyze the machining results by comparing the cutting force and cutting temperature simulation results The degree of influence of cutting parameters during the process.Then,analyze the characteristics and basic operation steps of the genetic algorithm,and design the variables of the parameters,establish the objective function,determine the constraints and genetic algorithm parameters,and optimize the cutting parameters.Finally,machining experiments with optimized cutting parameters.Grinding and testing of the blade,assembling and debugging tools on the tool loading machine,processing the equal-high spiral bevel gear,and testing the precision of the cutting gears.The results show that the optimized cutting parameters can improve the precision of the gears.
