| 摘 要： | 基于Dowson提出的最小油膜厚度方程,利用Matlab/Simulink仿真平台,建立齿轮啮合过程润滑状态的实时仿真系统。分析了齿轮啮合过程最小油膜厚度的时域变化情况,研究了齿轮润滑状态随转速、输入扭矩的变化关系,计算结果表明:随着啮合点向主动齿轮齿顶移动,其最小油膜厚度逐渐增大;齿轮点蚀经常发生在节圆附近。对节圆处的润滑状态进行了研究,发现随着输入转速的增加,轮齿节圆处的最小油膜厚度逐渐增加;随着输入扭矩的增加,轮齿节圆处的最小油膜厚度减小。

| Abstract: | A new model for the lubrication regime between the gear teeth was presented.According to minimum film thickness theory which was put forward by Dowson,this method was employed to calculate the time-varying minimum film thickness with Matlab/Simulink.The time-varying of minimum film thickness of gear was analyzed while the gear is operating.The change of lubrication state of gear under different loads and rotating speeds was studied.The results show that the minimum film thickness increases as the meshing po... |
