金属多孔含油轴承(简称多孔轴承)六十年代末、七十年代初已在我国大力推广应用。它与其它机械零件不同,前者是由机械技术人员设计和制造的;而后者则是机械技术人员设计,由冶金工作者制造的。因此,造成了多孔轴承在设计和制造上存在一些问题。许多机械设计手册中,缺乏多孔轴承的设计资料,加上设计者对多孔轴承了解不够,往往造成设计不合理。 Metal porous oil-bearing (referred to as porous bearings) late sixties, early seventies has been vigorously promote the use of our country. It is different from other mechanical parts, the former is designed and manufactured by mechanical technicians; the latter is designed by mechanical technicians and manufactured by metallurgists. Therefore, there are some problems in the design and manufacture of porous bearings. In many mechanical design manuals, the lack of porous bearing design information, coupled with the designer’s understanding of porous bearings is not enough, often resulting in the design is not reasonable.
