从国内有关资料查出圆柱斜齿轮两级减速器中间轴上,两个斜齿轮螺旋角的旋向有两种相反的设计[注],如图1和图2所示。在图1中,斜齿轮螺旋角的旋向相同,图2则旋向相反。我们现根据其受力情况分析如下. 若以图1为例,设转向如图示的标注方向,这时中间轴上大齿轮A的受力情况如图3所示,其轴向力 From the domestic relevant information found cylindrical helical gear two-stage reducer intermediate shaft, the helical angle of two helical gear rotation there are two opposite design [Note], as shown in Figure 1 and Figure 2. In Figure 1, helical helical angle of the same rotation, Figure 2 is the opposite rotation. We are now based on the analysis of their force as follows.If Figure 1, for example, set to the direction of the label as shown, then the middle axle gear A force shown in Figure 3, the axial force
