Conditions of Effect of Screw Torsion Deformation to Transmission Rigidity

Ming Qiang Yin

Abstract

Electromechanical rigidity of feed system with ball screw in NC machine has a major influence on positioning accuracy,torsion deformation is the important part of electromechanical rigidity,calculation of the axial deformation and torsion deformation for screw was discussed,the contrast between the axial deformation and torsion deformation showed that the torsion deformation affects electromechanical rigidity obviously.
