Study on Non-conformal Contact Characteristics of Ball Screw
摘要
Abstract
The contact between balls and screw races or nut races is a kind of typical non-conformal contact and its characteristics will influence greatly on ball screw's load capacity,transmission efficiency and positioning accuracy.Thus Hertz contact theory was adopted to construct the solution formula of ball screw's contact stiffness,then ball screw's contact characteristics in terms of axial load,design parameters and material properties were analyzed,and the contact deformation values of the contact between balls and screw races were obtained through finite element simulation method.The simulation results are close to the theoretic ones,which proves the correctness of the theoretic analyses.The present study offers theoretical support for the design and application of high speed,heavy load and precision ball screws.关键词
