摘　　要：提出了系统传动精度灵敏度的定义。根据2K-V型传动装置的数学模型,综合考虑各零件加工误差、装配误差和轴承间隙等误差因素对传动精度的影响,采用灵敏度计算的数值微分方法,获得了各误差因素对系统传动精度的灵敏度。基于灵敏度分析所获得的结论,找出了影响系统传动精度的主要误差因素。研究成果为提高2K-V型传动装置系统传动精度提供了重要的理论依据,同时也有助于其它高精密机械传动精度的研究。The definition of transmission accuracy sensitivity and the corresponding calculation method called numerical differential method are presented, and the transmission accuracy sensitivity indices with respect to each factor are obtained by sensitivity analysis of the computational model of 2K-V-type drive in consideration of factors such as manufacturing errors, assembly errors and bearing clearances. The main factors that influence the transmission accuracy are found and described on the basis of the sensitivity analysis result.
