Effect of contact angle and helix angle on slide-roll ratio under the uniform motion state of BSM
Key Laboratory of Advanced Manufacturing Technology, Beijing University of Technology, Beijing 100124, China
To study the effect of contact and helix angles on slide-roll ratio at the ball contact point under the uniform motion state of ball screw mechanism (BSM), a slide- roll ratio model was derived in the literature  were used in this paper. It also conducts a simulation analysis of the slide-roll ratio relationship between the uniform motion at the ball center and ball contact point under different contact angle and helix angle. As shown by the analysis, with the increase in the BSM’s contact angle, the slide/roll ratio at the contact point decreased, and the contact angle had a relatively significant effect on the slide/roll ratio; however, with the decrease in the BSM’s helix angle, the slide/roll ratio at the contact point decreased, and helix angle had a relatively insignificant effect on the slide/roll ratio.
