摘要

在精密钢球传动接触力学和运动学研究的基础上,应用Hamrock-Dowson公式推导出精密钢球传动啮合副最小油膜厚度计算公式。应用数值计算方法,研究摆线齿形的短幅系数和滚圆半径及钢球半径等基本参数对啮合副最小油膜厚度的影响规律。分析判别啮合副的润滑状态,提出啮合副处于完全弹流润滑状态时参数选择的计算方法,并计算出基本参数的取值域。为精密钢球传动的设计和应用提供了理论依据。

Abstract

On the basis of the study of contact mechanics and kinematics of precision steel ball transmission,the minimum film thickness formula of precision steel ball transmission meshing vice is derived by applying Hamrock-Dowson formula.The influence rule of the basic parameters such as the short amplitude coefficient of cycloidal tooth profile,rolling circle radius and steel ball radius on the meshing pair minimum film thickness is studied by applying numerical calculation method.The lubrication condition of meshing pair is analyzed and discriminated,the calculation method of the parameter selection of meshing pair in a state of complete elastohydrodynamic lubrication is proposed with calculating the range of the basic parameters.The theory basis of design and application for precision steel ball transmission is provided.
