四、齿面故障诊断1.轮齿齿廓的变化图6显示在疲劳试验过程中,pmax=700MPa的条件下,齿廓误差的变化情况。啮合的小齿轮的齿廓误差在疲劳试验中几乎没有变化。粘有应变仪的那个轮齿编号为No.1,其他轮齿按齿轮进行啮合的次序依次排号。在疲劳试验前,N2=0,齿廓的误差来自压力角的误
Fourth, the tooth surface fault diagnosis 1. Gear tooth profile changes Figure 6 shows the fatigue test, pmax = 700MPa conditions, the profile error changes. The tooth profile error of the meshing pinion almost did not change during the fatigue test. The gear with sticking strain gauge is No. 1, the other gears are arranged in the order of gear engagement. Before fatigue test, N2 = 0, the error of tooth profile comes from the error of pressure angle
