摘要
对水轮发电机定子线棒端部倾斜段采用渐开线方式进行设计,在保证接线端径向尺寸和轴向尺寸的前提下,给出了渐开线所在圆锥面的半锥角所满足的数学方程,并运用Excel VBA编程手段对半锥角进行了精确求解。在此基础上,运用三维建模软件NX对定子线棒完成了参数化的设计,为线棒的模具设计提供了更精确的参考依据。
Involute shape is designed for the inclined section of the end of hydro generator stator coil.In order to keep the radial and axial position of the terminal, the mathematical equation of the half cone angle of the conical surface where the involute lies is given, and the equation is solved by Excel VBA programming. Using the value of cone angle and other known parameters, the parametric model of stator coil is built by 3D software NX and it provides a more accurate reference for tool design of stator coil.
