Analysis and research of the axial stiffness of ball screw system
摘要
Abstract
Now the demand on ball screw stiffness is increasingly high when it is developed toward high -speed and high-precision direction .And the influence on the axial accuracy of CNC machine tools by the axial stiffness of ball screw is more and more obvi -ous.The axial stiffness is analyzed and researched by building the finite element model for the two usual forms of the ball screw system.关键词
