Main drive performance directly affects the machining accuracy and productivity of the machine, to improve product quality and grades of great significance. In this thesis, the spindle cutting torque, stress analysis and calculation of the bearing spindle, and calculates the front and rear bearing life. Features of this paper are: the study of the spindle torque, the spindle increase processing capacity. Through analysis of the main shaft of the force and the support span, the spindle has a higher stiffness. By bearing preload and rational use of lubrication and sealing, improved bearing life. Through the main drive design, optimized for main drive, it has a profound influence on the development and application of numerical control lathes. Key words: CNC lathes, the main drive system, the spindle assembly, spindle 购买后包含有 CAD 图纸和说明书,咨询 Q401339828 I 目录前言.................................................................................................................................... 1 第1章绪论..................................................................................................................... 2 数控机床国内外研究现状及发展局势........................................................... 2 数控机床国内外研究现状......................................................................... 2 数控机床国内外发展趋势..................................................................... 3 数控机床的组成..................................................................................................
