摘　　要：本文对三联角接触球轴承的预紧力进行了实验研究，定量分析了这种轴承的预紧力与主轴组件的静刚度、动态特性和不同转速下的温升之间的关系，提出了选择预紧力的科学依据。In this article, an experimental research on the preloading force on a group of three angular contact ball bearings in one support is carried out, the relations between the preloading force and static stiffness, dynamic performance and temperature rise at different spindle speeds are quantitatively analyzed, and the scientific basis for selecting the preloading force is provided.

关 键 词：机床 主轴 预紧力 角接触球轴承
