The Entire CNC Machining Methods And Software Of Epicycloid Gear

As the rapid development of the automobile manufacturing industry, as the most important part of the automobile accessories, the development of gear's design and machining mode has got more attention than before. The epicycolid bevel gear and hypoid gear (bevel gear for short hereinafter) is widely used in the rear axle of the transmission. Its advantages as great carrying capacity, steady driving system, low noise, and compact conformation make it an important accessory of the vehicle power transmission system.Bevel gear's geometric parameter design and processing adjustment parameter transmission performance evaluation and so on computation accurate immediate influence bevel gear meshing transmission quality, working life and reliability key parameters. At present, the Klingelnberg corporation's CDS software is widely applied in the international epicycolid bevel gear and hypoid gear manufacture industry. Because the bevel gear's designing and machining technique are monopolized by Switzerland ex-Oerlikon corporation and German Klingelnberg corporation. the technical data drifting into China is limited, Chinese scholars in the field study also relatively small, The researches about this area are less in home, therefore the principle of its milling process, adjusting the terms of the manufacture of complete sets of processing equipment to master the technology are less, and foreign advanced levels vary considerably. At present overseas widely uses the entire numerically-controlled machine tool processing cycloidal tooth bevel gear, this method processing efficiency is high, bevel gear's precision which processes is good. The home also mainly uses traditional the cycloidal tooth bevel gear milled tooth machining cycloidal tooth bevel gear, but are few to the entire numerical control processing cycloidal tooth bevel gear's research, Therefore research cycloidal tooth bevel gear's geometric parameter, adjustment parameter computation and entire numerical control processing cycloidal tooth bevel gear's principle, to accelerates the domestically produced entire numerical control cycloidal tooth bevel gear gear cutter and complete set of equipment's development, raising our country cycloidal tooth bevel gear's processing level to have the vital significance.This article first according to the gear meshing theory and the related handbook, conducts the fundamental research to the cycloidal tooth bevel gear geometric parameter design and the computation cutting tooth adjustment parameter. In this fundamental research foundation, it establishes Oerlikon system cycloidal tooth bevel gear tooth face geometric parameter like diameter arrow, french arrow and so on unification computation model, has analyzed its solution method, and conducts the tooth face contact analytical study according to this model. In the above fundamental research foundation, using Visual the C++ programming tool, researches and develops under the Windows environment cycloidal tooth bevel gear designing software system. Through to the cycloidal tooth bevel gear entire numerical control processing's control principle research, has established the cycloidal tooth bevel gear entire numerical control processing mathematical model, and acted according to this model analysis cycloidal tooth bevel gear entire numerical control processing the knife position computational method. According to cycloidal tooth bevel gear entire numerical control processing control principle, through construction cycloidal tooth bevel gear entire numerical control processing hypothesized cutting tooth platform in VERICUT numerical control simulation software, and carries on the cutting tooth simulation experiment, has confirmed this cycloidal tooth bevel gear entire numerical control processing mathematical model and cycloidal tooth bevel gear design software system computation accuracy.
