摘　　要：为克服原核用关节轴承摩擦因数高、易磨损、不能长时间持续工作等缺陷,对该轴承采用镶嵌自润滑材料石墨进行减摩设计。在轴承内圈外表面设计石墨排列方式,基于ANSYS Workbench对轴承应力、变形、寿命进行分析,结果表明:新设计轴承在高温下具有自润滑减摩作用,在许用载荷下轴承疲劳寿命为高周疲劳,满足实际工作要求。In order to solve the shortages of original spherical plain bearings used in nucleus such as high frictional coefficient,easy to wear and not working for a long time,an antifriction design is done by inlaying self-lubricating material of graphite.The arrangement mode of graphite is designed on outer surface of bearing inner ring.The stress,deformation and life of bearings are analyzed based on ANSYS Workbench.The results show that the new designed bearings have self-lubricating antifriction effect under high temperature.The fatigue life of bearings is high cycle fatigue under allowable load.The new designed bearings are able to satisfy actual work requirements.
