在机床设计中,有时由于结构上的限制的需要,主轴部件采用三支承结构。从力学观点来看主轴部件静刚度,三支承主轴部件有什么特点?有关参数如何选择才能使主轴部件静刚度为最大?这是本文所要研究的主要问题。文中所述的一些看法有待深入研究和值得进一步商榷。 本文是文献[1]的继 In machine tool design, sometimes due to structural constraints, the spindle components use three support structures. From mechanical point of view static stiffness of the main shaft components, the three bearing spindle components What are the characteristics? How to choose the parameters to make the maximum static stiffness of the spindle parts? This is the main issue to be studied in this paper. Some of the views described in the paper need further study and is worthy of further discussion. This article is the successor of the literature [1]
