摘　　要：高速主轴作为高速高精密加工机床的关键技术,直接决定着机床的各项工作性能。文中提出一种对粘度-轴承间隙寻优,从而实现主轴高性能的高速高精密主轴设计方法,并设计出新型绿色、粘度可控的高水基液作为润滑剂,随后通过采用动静压陶瓷滑动轴承的高速主轴热弹流数值计算,确定了润滑剂粘度及主轴系统相关结构参数,最终完成了该高速主轴的结构设计。As the high speed spindle is the key technology of the high speed and highly precision spindle machine tool,which directly influences the various operating performances of the machine.This paper presents a new design method for high speed and highly precision spindle in which the match of lubricant viscosity and bearing clearance is optimized to improve the performance of spindle.A green and viscosity controllable high water based fluid which is adopted as lubricant of spindle is designed and tested.Optimum lubricant viscosity and structure parameters of spindle system are deduced based on thermal elastohydrodynamic numerical calculations of high speed hybrid ceramics sliding bearing and spindle.Finally the structure design of high speed and highly precision spindle is completed.
