| 摘 要： | 为了研究水润滑橡胶尾轴承鸣音产生的机理,在水润滑橡胶尾轴承鸣音台架模拟试验的基础上,结合橡胶尾轴承的摩擦特性,对试验结果进行了初步分析总结,揭示了各因素对水润滑橡胶尾轴承鸣音临界工况的影响规律。结果表明,水润滑橡胶尾轴承鸣音出现与否,主要取决于工作过程中轴承与轴颈的直接接触面积以及摩擦系数-速度曲线负斜率。

| Abstract: | In order to study the mechanism of squeal of water lubrication stern tube rubber bearing,the experiment has been carried out to study the mechanism of squeal of water lubrication stern tube rubber bearing.Combined with the friction property of water lubrication stern tube rubber bearing the rustle is analyzed.The result shows that the appearance of the squeal depends on the contact area between bearing and journal and negative slope of the friction-speed curve of the rubber bearing. |
