改进的变渗透度含油轴承

本文介绍了作者研制的一种沿圆周方向和半径方向均变渗透度含油轴承，与以往的变渗透度含油轴承相比，其内部结构更为合理，其高低渗透度区过渡平缓，应力集中得到缓和，在制造和使用过程中不易破裂。理论分析与实验研究均表明：与普通含油轴承相比，其性能更为优越。

A New Type of Variable Permeability Porous Bearings.

A variable permeability porous bearings developed by the authors has been described. The bearings exhibit & moderate transition area from high to low permeabililty which alleviates stress concentration so that the bearings are not liable to be broken during manufacture and use. The theoretical analysis and experimental results show that the tribological behavior of the new type of porous bearings is much superior to that of conventional porous bearings while all other conditions being equal.
