摘　　要：对横轴式转刷型表面曝气机用三级圆锥-圆柱齿轮减速器低速级圆柱齿轮副出现因点蚀、剥落特别是断齿而失效的现象进行了分析,从速比分配、材质选用等方面进行了设计改进。The failure phenomenon of pitting, scaling and teeth break in low speed stage cylindrical gear of three stages bevel - cylindrical gear reducer for intersecting axis surface aerator is systematically analyzed. The improvement design of gear ratio distribution, material selection is carried out.
