| 摘 要： | 在弹性流体动压润滑理论和平面蜗轮传动啮合特点研究基础上,提出了该传动的弹性流体动压润滑模型。计算了整个接触区内的最小弹流膜厚,分析了该传动的弹流润滑状态,揭示了最小膜厚的分布规律:蜗杆啮入端的润滑状况优于啮出端,蜗杆齿顶的润滑状况优于齿根。分析了工况参数和优化变量对该传动润滑性能的影响情况,结果表明:改善平面蜗轮传动润滑性能较为有效的方法是优化压力角和增大蜗杆分度圆直径。

| Abstract: | Based on study of elastohydrodynamic lubrication (EHD) and meshing theory of planar worm gear drive,EHD model for the drive is proposed.Minimum film thickness on the whole contact area is calculated.EHD status for the drive is analyzed.The distributions of film thickness show that,EHD status during entry engagement is better than that during exit engagement,and EHD status of worm addendum area is better than that of dedendum area.Influencing factors such as work conditions and optimized parameters along wit... |
