| 摘 要： | 多油叶轴承比单油叶轴承稳定性好，但摩擦损耗较大。为了克服这一缺点，在多油叶轴承和轴颈间加入一个浮环，从而达到提高承载能力、减少摩擦损耗的效果。采用流体力学边界元方法计算了六叶错位浮环轴承的流体动力学特性，得到了几种不同偏心率下，润滑区域内的流场分布、轴瓦表面的压力分布及浮环表面的压力分布；并对无浮环的六叶错位轴承与六叶错位浮环轴承的内摩擦损耗进行了比较。

| Abstract: | A multi-leaf bearing has a better stability than a single-leaf one.However,there is a greater friction loss with it.To overcome this weakness,we place a floating ring between the multi-leaf bearing and the journal so as to improve the carrying capacity and reduce the friction loss.The hydrodynamic characteristics of the six-leaf dislocated floating-ring bearing are studied with the aid of the hydrodynamic boundary element method.As a result,the flow field distribution in the lubrication regime and the press... |
