摘　　要：为揭示条纹型单元织构化推力轴承的干摩擦磨损行为,以81107TN推力圆柱滚子轴承为对象,在轴承轴圈表面制备不同宽度和不同深度的条纹型单元,然后从摩擦系数、磨损量、表面形貌等方面,研究了条纹型单元的深度和宽度对“滚道-滚动体-保持架”系统干摩擦磨损性能的影响。试验结果表明:在干摩擦条件下,条纹织构化轴承的摩擦系数相比无织构光滑轴承有所升高,改变条纹的深度和宽度可以影响摩擦系数的变化范围;条纹织构可以显著增强轴承的抗磨能力,且与摩擦系数呈负相关,织构宽度为50μm,深度为7μm的轴承表现最明显,相比光滑无织构轴承磨损量降低约75.6%;条纹织构化轴承的磨损程度和范围,相比光滑无织构轴承明显减小,这得益于织构边缘对基体起到了保护作用。To reveal texture stripe type units of dry friction and wear behavior of the thrust bearing,with81107TN thrust cylindrical roller bearing,axis bearing in the circle of different width and depth of surface preparation stripe type unit,and then from the coefficient of friction,wear,surface morphology and so on,studies the depth and width of stripe type unit“Raceway-RollerCage”system,the influence of dry friction and wear performance.The experimental results show that the friction coefficient of strip-textured bearing is higher than that of non-textured smooth bearing under the condition of dry friction.The strip texture can significantly enhance the wear resistance of the bearing,and it is negatively correlated with the friction coefficient.The bearing with a texture width of 50μm and a depth of 7μm shows the most obvious performance,and the wear amount of the bearing is about 75.6%lower than that of the smooth non-woven bearing.The wear degree and range of strip textured bearings are significantly reduced compared with smooth non-textured bearings,which is due to the protective effect of textured edges on the matrix.
