摘要:
为了从本质上揭示双螺母垫片预紧式滚珠丝杠副中滚珠与滚道接触界面间的滚滑接触特性,基于滚动接触力学中滚滑接触理论,构建了滚珠丝杠副中滚珠与滚道接触面间蠕滑率和自旋率的表达式。利用此表达式并结合Kakler理论,建立了双螺母垫片预紧式滚珠丝杠副中滚珠与滚道接触界面间的摩擦力模型。通过比较启动摩擦力矩的理论计算值与实验测量值,验证了此摩擦力模型的可靠性。利用此模型计算分析了接触面上蠕滑率/自旋率随工作条件和结构参数变化的规律。结果发现:滚珠与滚道接触面上的蠕滑率和自旋率主要受此接触面上接触角的影响,而蠕滑率和自旋率主要影响了滚珠与滚道接触面间的滑动行为。
Abstract:
In order to reveal the characteristics of rolling contact between the ball and the race of the preloaded double-nut ball screw,based on the theory of rolling contact theory in rolling contact mechanics,the sliding forces between the ball and nut raceway are calculated.A creepage analytical model for the ball screw is eventually established.The ball screw tests are performed on a special machine.Good agreement has been obtained by comparing the predictions of the new analytic torque model with the test results.The quantitative relationship between the creep rate/spin ratio with operating conditions and structural parameters are analyzed using this model.The results show that the creep rate and the spin rate of the contact surface of the ball are mainly influenced by the contact angle,while the creep rate and spin rate mainly affect the sliding behavior of the contact between balls and races.
