摘要： 从滚珠丝杠副的结构参数入手,计算出滚珠丝杠副的主曲率半径,并做出接触角、螺旋升角与主曲率的关系曲线.以赫兹空间接触理论为依据,对滚珠丝杠副的接触变形进行理论计算,并对接触角、螺旋升角与接触变形、接触刚度之间的关系做进一步探讨.采用ANSYS有限元模型对上述接触变形计算结果进行验证.结果验证了理论模型的正确性,表明适当增大接触角、螺旋升角可以有效改善滚珠丝杆副传动性能.

Abstract: The principal curvature radius of a ball screw pair was calculated using the structural parameters of the ball screw pair, and the curvilinear relationship between helix angle, contact angle, and principal curvature was plotted. Based on Hertz contact theory, contact deformation of the ball screw pair was calculated. Contact stiffness was then investigated using the relationship between contact angle, helix angle, and contact deformation. Calculated contact deformation values were verified with ANSYS FEM. The results demonstrated the validity of the theory. Contact characteristics of ball screw pairs can be effectively improved by increasing helix angle and contact angle.
