Model of Precision Loss for the Precision Ball Screw

Article Preview

Abstract:

Aiming at the precision retaining ability problems of the precision ball screw, the modeling on the motion precision loss process under load condition is studied. The mechanics and deformation of the interface of ball and groove under load condition is analyzed by using the classical mechanics and Hertz contact theory, also a precision loss model for precision ball screw is established based on the dynamic characteristics analysis of the ball screw. Regardless of the external interference, the impact of various factors on the precision loss is analyzed and calculated.
