Abstract:
To study the effect of the contact angle and helix angle on slide-roll ratio at the ball contact points under the accelerated motion state of ball screw mechanism(BSM), the curve theory in differential geometry and the homogeneous transformation matrix are used to establish the acceleration kinematics model of BSM. The model can be used to describe the accelerated motion relationships among the screw, balls and nut, calculate the acceleration of relative motion at the contact points between the balls and raceways, and analyze five accelerated motion rules between the balls and raceways. It also conducts a simulation analysis of the slide-roll ratio relationship between the accelerations at the ball center and the contact point of ball under different contact angles and helix angles. As shown by the analysis, with the increase in the BSM’s contact angle, the slide-roll ratio at the contact points decreases, and the contact angle has 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 points decreases, and the helix angle has a relatively insignificant effect on the slide-roll ratio. By measuring the accelerations of both the screw and nut under the accelerated motion state, it also verifies the existence of the slide-roll mixed motion at the ball contact point A between the ball and the screw raceway and pure rolling at the ball contact point B between the ball and the nut raceway during the accelerated motion.
为研究滚珠丝杠副在加速运动状态下, 接触角和螺旋升角对滚珠接触点处滑滚比的影响, 利用曲线微分几何理论和相似坐标转换矩阵建立滚珠丝杠副的加速运动学模型.通过该模型可以获得丝杠、滚珠和螺母加速运动特性, 滚珠与滚道接触点处的相对运动加速度值和滚珠与滚道之间的5种加速运动规律.仿真分析不同接触角和螺旋升角情况下的滚珠圆心加速度值和滚珠接触点的滑滚比.分析发现, 随着滚珠丝杆副接触角的增加, 接触点的滑滚比降低, 并且接触角对滑滚比影响较大;相反, 随着螺旋升角的减小, 接触点的滑滚比降低, 但螺旋升角对滑滚比的影响较小.通过实测滚珠丝杠副加速运动状态下丝杠和螺母加速度值, 验证滚珠丝杠副在加速运动状态下滚珠与丝杠滚道接触A点存在滑滚混合运动, 滚珠与螺母滚道接触B点存在纯滚动.
