水润滑艉轴承负载能力的分析

以具有弹性的塑料轴承为例，分析相应的流体动力润滑机理以及水槽结构形式对其运行特性的影响．结果表明，一个连续的不开槽的轴承表面比一个开槽的轴承表面允许水力膜形成更高的动压力；长径比大的轴承，其负载能力亦相对较大。

Analyses of the load capacity of water lubricated stern tube bearing

With elastic plastic bearing as an example,the relevant theory of hydrodynamic lubrication and the effects of the grooved structure on operating characteristic are analysed.The results show that a continuous bearing surface without grooves allows the hydrodynamic film to build to a higher pressure than the one with grooves and the bearing designed at large L/D has a higher load capacity.
