【摘要】：CRH5动车牵引齿轮采用弧齿锥齿轮，动车的整体性能与牵引齿轮有着密切的关系。本文以CRH5动车牵引齿轮为研究对象，通过VB、MATLAB和Pro/E等软件，分析和研究了弧齿锥齿轮实体建模与轮齿几何接触问题，本论文的主要研究内容如下： 1．通过对CRH5设计要求的分析，采用了格里森公司提出的齿根倾斜修正法，通过VB编程计算得出CRH5动车牵引齿轮的轮坯几何参数。 2．基于局部综合法构建了与所研究的动车牵引齿轮相对应的数学模型，通过MATLAB软件对计算过程进行编程计算，得出了CRH5动车牵引齿轮的机床切削加工调整参数。 3．根据弧齿锥齿轮加工过程中机床的结构和各部分之间相互运动关系，通过构建空间坐标系，利用矩阵实现空间坐标变换，，结合齿轮空间啮合原理推导出CRH5动车牵引齿轮的大小轮的齿面方程。利用MATLAB编程计算出齿面上分散点的坐标值，通过MATLAB中的surf()函数在MATLAB中建立大轮的实体模型来分析所计算得到的坐标点的准确性。再把生成的点以一定的格式保存，导入Pro/E三维软件中进行实体建模，并装配后进行运动和干涉检查，从三维模型验证所用理论和计算方法的正确性。 4．利用由局部综合法所求得的机床切削加工调整参数，通过MATLAB编程实现CRH5牵引齿轮的齿面接触分析（TCA）,分别确定出轮齿中点、大端和小端齿面上的接触迹线的形状和传动误差曲线图，并对所得到的曲线图进行了分析和解释，验证了大小轮切削加工参数的合理性。
[Abstract]:Arc bevel gear is used in traction gear of CRH5 motor car. The whole performance of motor car is closely related to traction gear. In this paper, CRH5 traction gear is taken as the research object. By means of the software of VB,MATLAB and Pro/E, the problem of the contact between the solid modeling of the spiral bevel gear and the gear tooth geometry is analyzed and studied. The main research contents of this thesis are as follows: 1. Through the analysis of CRH5 design requirements, the method of tooth root tilt correction proposed by Gleason Company is adopted. The geometric parameters of wheel blank of traction gear of CRH5 train are calculated by VB programming. 2. Based on the local synthesis method, the mathematical model corresponding to the studied traction gear is constructed, and the calculation process is programmed by MATLAB software. The cutting adjustment parameters of CRH5 traction gear are obtained. 3. According to the structure of the machine tool and the relationship between the parts of the machine during the machining process of arc bevel gear, the spatial coordinate system is constructed. The tooth surface equation of the large and small wheel of CRH5 traction gear is derived by using matrix to realize the transformation of space coordinate and combining with the principle of gear space meshing. The coordinate values of the scattered points on the tooth surface are calculated by MATLAB programming, and the accuracy of the calculated coordinate points is analyzed by using the surf () function in MATLAB to establish the solid model of the large wheel in MATLAB. Then the generated points are saved in a certain format, and then imported into Pro/E 3D software for entity modeling, and the motion and interference inspection are carried out after assembly. The correctness of the theory and calculation method used in the 3D model is verified. 4. The adjustment parameters of machine tool machining are obtained by using the local synthesis method. The tooth surface contact analysis of CRH5 traction gear is realized by MATLAB programming. The shape and transmission error curve of the contact trace line on the middle point, large end and small end tooth surface of the gear are determined by (TCA), and the obtained curves are analyzed and explained. The reasonableness of machining parameters of large and small wheel is verified.
