S195柴油机齿轮箱的小齿轮齿数是18齿,与之相啮合的大齿轮的齿数是44齿。目前生产厂家的齿形加工工艺多是以插齿为主,这就不能排除插齿加工的齿轮在啮合时发生过渡曲线干涉现象。一、齿轮过渡曲线干涉的分析图1是插齿刀加工小齿轮的啮合简图。(?)。为理论啮合线,K_1,K_2分别是插齿刀及小齿轮齿顶与(?)线段的交点,(?)为实际啮合线。图2表示该插齿刀加工出来的小齿轮与大齿轮的啮合图,大齿轮齿顶圆与理论啮合线(?)的交点K_1′。图3所示 S195 diesel gear box pinion gear is 18 teeth, meshing gear with 44 teeth. At present, the manufacturer’s toothed processing technology is mainly based on gear-in, which can not be ruled out gear tooth gear meshing transition curve interference occurs. First, the gear transition curve interference analysis Figure 1 is a gear shaper gear meshing diagram. (?). Is the theoretical meshing line, K_1 and K_2 are the intersection points of gear tooth tips and (?) Line segments of gear shaper and pinion, respectively, and (?) Is the actual meshing line. Fig. 2 shows the meshing diagram of the pinion gear and the large gear machined by the gear shaper. The intersection point K_1 ’of the large gear tooth tip circle and the theoretical meshing line (?). Figure 3 shows
