径向珩轮齿面形状异常复杂,难以用解析法精确描述,实现修磨量的解析计算比较困难。因此通过三维建模软件UG/NX实现了对工件齿轮的的参数化建模,确立工件齿轮与珩轮毛坯的空间位置关系,仿真径向珩轮的加工过程,成功得到了径向珩轮的精确实体造型,最终得到单个轮齿齿面的修磨量。通过分析得出结论:在齿宽中部处修磨量最大,并且越往齿宽边缘修磨量越小,并且修磨量数据基本呈现关于齿宽中面对称;齿廓修磨量随着半径的的减小而减小,说明得到的径向珩轮齿廓曲线已不是渐开线,而是越靠近齿根处齿厚越大,这样能够提高珩轮刀具的强度和寿命。上述研究为径向珩轮的加工制作奠定了基础。
Radial honing gear surface shape is extremely complicated, it is difficult to accurately describe the analytical method, the amount of grinding to achieve the analytical calculation is more difficult. Therefore, through the three-dimensional modeling software UG / NX, the parametric modeling of the workpiece gear is realized, the spatial relationship between the workpiece gear and the honing wheel blank is established, the radial honing wheel is simulated, the radial honing wheel Accurate physical modeling, the final get a single gear tooth surface grinding amount. Through the analysis, it is concluded that the amount of grinding is the largest in the middle of the tooth width, and the smaller the amount of grinding to the edge of the tooth width, and the amount of grinding data is basically symmetrical about the tooth width; The decrease of the radius decreases, indicating that the obtained radial honing gear profile curve is not involute, but the closer the tooth root, the greater the tooth thickness, which can improve the honing tool strength and life. The above research laid the foundation for the processing of radial honing wheels.
