GB10095—88《渐开线圆柱齿轮精度》国家标准,对齿形误差△f_f的定义为:在端截面上,齿形工作部分内(齿顶倒棱部分除外),包容实际齿形且距离为最小的两条设计齿形间的法向距离。设计齿形可以是修正的理论渐开线,包括修缘齿形、凸齿形等,如图1所示。渐开线圆柱齿轮鼓形齿(即凸齿形)和修缘齿齿形误差,就是用设计齿形曲线图来评定的 一、设计齿形
GB10095-88 “Involute Cylindrical Gear Accuracy” national standards, the definition of gear error △ f_f is: in the end section, the toothed work part (except for chamfer top part), to accommodate the actual tooth shape and the distance The minimum normal distance between two design teeth. The design tooth shape can be a modified theoretical involute, including the shape of an involute tooth, a convex tooth shape, etc., as shown in FIG. 1. Involute cylindrical gear drum gear (ie, convex tooth) and repair tooth profile error, is to use the design toothed curve to assess the design of a toothed
