摘　　要：动态预紧转矩不仅可以反映滚珠丝杠副加工装配精度,而且也可以预测滚珠丝杠副的热伸长、能量损耗等性能,因此是滚珠丝杠副综合性能检测的主要指标。国内外主要制造商对滚珠丝杆副的理论动态预紧转矩的标准却各不相同,文中分别比较了NSK、柯尔特、山东博特公司对理论动态转矩的性能检测标准,并应用不同的传动效率计算方法分析了这几种动态转矩的检测标准的特点和应用范围。文中的结论不仅对滚珠丝杠副的装配和设计,而且对于滚珠丝杠副的选型有较好的指导作用。Dynamic friction torque is an integrated performance index of ball screw mechanism because it not only affects the assembling precision of the ball screw but also has much relationship with the thermal de-formation and mechanical efficiency. However the domestic and foreign measuring standards of dynamic friction torque are different, in order to investigate the different characteristics and application, different methods to calculate the mechanical efficiency are introduced to compare mechanical efficiency from NSK, Korta and BT. In this paper, the conclusion is guidance for assembling and design of the ball screw mecha-nism.
