ISO 23848-2:2009规定了AI型、AII型和R型球花键设计和使用的基本动载荷额定值、基本静载荷额定值和基本额定寿命预测的计算方法。它还确定了这些球花键的基本静态和动态扭矩额定值。

ISO 23848-2:2009 specifies the calculation method of basic dynamic load rating, basic static load rating and basic rating life prediction for the design and use of ball splines of type AI, type AII and type R. It also establishes the basic static and dynamic torque ratings for these ball splines.
