    已知一对正确安装的渐开线标准直齿圆柱齿轮传动,中心距a=100 mm,模数 m=2 mm,压力角α=20°。传动比i=ω1/ω2=1.5,齿轮2的分度圆、基圆、齿顶圆、齿根圆直径分别为:
    A: d2=118 mm,db2=112.346 mm,da2=98 mm,df2=93 mm
    B: d2=110 mm,db2=102.346 mm,da2=118 mm,df2=113 mm
    C: d2=80 mm,db2=75.175 mm,da2=84 mm,df2=75 mm
    D: d2=120 mm,db2=112.763 mm,da2=124 mm,df2=115 mm
