摘　　要：镶嵌孔形态、分布及镶嵌比例是自润滑关节轴承疲劳寿命和结构强度主要影响因素,针对轴承镶嵌孔径、比例、深度和分布未系统研究的问题,对某大型压榨机自润滑关节轴承进行设计和分析。采用有限元分析计算方法,对比分析了镶嵌孔半径为4mm至10mm,镶嵌比例为15%至40%,镶嵌孔深为3mm至12mm的不同关节轴承的应力分布和交变疲劳寿命,研究结果表明镶嵌比例20%、镶嵌深度6mm、开孔半径8mm的轴承为最优设计结果。最后以不同轴承为例,采用相同研究方法,通过对比和结果分析,验证设计结果的正确性。Shape,distribution and inlaid ratio of the inlay hole are the main influential factors on the fatigue life and structural strength of self-lubricating joint bearings.A large self-lubricating press joint bearing is designed and analyzed of the issues focused on the inlaid aperture,proportion,depth and distribution which were seldom researched specifically before.Finite element analysis was applied to compare the stress distribution and alternating fatigue life of different joint bearings with the inlaid hole radius from 4mm to 10mm,the inlaid ratio of 15%to 40%and the depth of inlaid hole around 3mm to 12mm.The results show that joint bearings,which have 20%of the inlay proportion,6mm of the inset depth and 8mm of the opening radius have the best performance.Finally,different bearings were taken as examples,and the same method is used to verify these results.
