单列圆锥滚子轴承
当量动载荷
P=Fr[KN]当Fa/Fr≤e时
P=0.4Fr+YFa[KN]当Fa/Fr>e时
单列圆锥滚子轴承成对使用时(基本外形尺寸可不同),在计算轴承的当量动载荷时,必须计入径向载荷引起的附加轴向力。单列圆锥滚子轴承的附加轴向力S,
可近似按下式计算:
S=Fr/2Y
双列和四列圆锥滚子轴承
当量动载荷
P=0Fr+Y1Fa [KN]当Fa/Fr≤e时
P=0.67Fr+Y2Fa[KN]当Fa/Fr>e时
单列圆锥滚子轴承
PO=0.5Fr+YOFa[KN]
若P0
PO=Fr+YOFa[KN]
Fr和Fa均指作用于单列,双列和四列轴承上的总载荷。
计算系数e、Y、Y1、Y2、Y0列在轴承尺寸表中。
