Milling Process Simulation And Blade Improvement Study Based On Machining Tool Of Curve Tooth Bevel Gear

Bevel gear transmission is the most effective and practical way to transfer the rotary motion between intersecting axis and cross axis, which has been widely used in many fields, such as aircraft, railway, shipping, mining machinery and so on. Especially the bevel gear with curved teeth, which characteristics is better than that of common gear, is widely used in many important occasions. Currently, the bevel gear with curved teeth is mainly processed in the special milling machines. The cutter tooth often occurs abrasion, tipping and fracture condition because of the complex milling processthe, which has affected its service life, processing precision and increased its processing costs. Therefore, it is very important to solve the problem of cutting tool in the machining of curved tooth bevel gears.In order to solve the above problems, this paper is based on the new cutting method--shape line cutting method. Analyzing the influence on the cutting processing performance based on actual production existing problem after the simluation of machining process, and then improve the cutting tool. Because of the complexity of the cutting force in the actual milling process, this paper simplifies the structure of the original workpiece and tool, and then imports the simulation software of the milling process. According to the different milling width, both the milling force and temperature changes of cutting tools and the stress and strain analysis of workpiece milling area is analyzed, it describes the variation of main parameters of cutter milling area in detail; By changing the simulation parameters of the cutter tooth, analyzes the effects of different cutting parameters on tool main milling force, and obtain theoretical calculation results of main milling force, and then compared with simlution results to verify the accuracy of simulation in this paper. After the finite element analysis of the blade structure on the cutting tool, the design scheme of the blade is established according to the simulation results and the structure of the data obtained. In the end, the improved results are verified by the comparison of the stress, strain and abrasion.The analysis of method, process and conclusion of this paper has a certain reference and guidance significance for the development of such tools in the future.
