基于UG的径向珩轮齿面造型分析

Analysis of Radial Gear Honing Wheel Tooth Flank based on UG

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。

The tooth flank ficult to accurately describe by shape of plunge gear honing wheel is extraordinarily complex, it is dif- the analytical method, the analytical calculation of grinding capacity is more difficult. Through three-dimensional modeling software UG / NX, the parametric model of the workpiece gear is realized, the spatial positional relationship between the workpiece gear with a honing wheel blank is established, the process of radial gear honing wheel is simulated, a precise radial gear honing wheel solid modeling is successfully obtained, and ultimately, the single the tooth flank grind- ing capacity is got. By analyzing the conclusion, in the middle of the tooth width grinding capacity is at maximum, and more closer to the edge of the tooth width, the smaller the amount of grinding capacity and grinding capacity data base showing on symmetrical about middle transverse section, tooth profile grinding capacity as the decrease of the radius decreases, it is indicating that the radial gear honing wheel tooth profile is not the involute, but closer to the tooth root of the tooth thickness is greater tooth, and this can increase the honing wheel strength and life of the tool. This study laid the founda- tion for the manufacture of plunge gear honing wheel.
