摘　　要：为了探究织构化滚动轴承贫油摩擦磨损过程的振动与噪声特性,以81107-TN型推力圆柱滚子轴承为研究对象,先采用激光表面织构化技术在轴圈滚道表面制备圆形凹坑织构,然后在摩擦磨损试验台上进行试验和信号采集。对试验结果的分析和对比表明:表面织构在贫油条件下具有降噪减振的作用,且随着凹坑织构深度、直径的增加,这种抑制效果会减缓。与光滑轴承相比,T3(直径100μm,深度20μm)的耐磨减阻与降噪减振的综合性能最好,摩擦界面噪声强度降低8.5%,振动加速度振幅降低29.7%。这将为后续织构化滚动轴承的可靠性研究提供重要参考。In order to explore the texture change rolling bearing vibration and noise characteristics of boundary friction and wear process,based on the 81107-type TN thrust cylindrical roller bearing as the research object,first using laser surface texture technology in the preparation of circular pit shaft ring raceway surface texture,then on the friction and wear test bench test and the signal acquisition.The analysis and comparison show that the result of the test:surface texture in boundary conditions have the noise reduction of vibration reduction effect,and with the increase of pit texture depth,diameter,the inhibition effect will be slow.Compared with the smooth bearing,T3(100μm in diameter,depth of 20μm)has the best comprehensive performance of wear resistance reduction,noise reduction and vibration reduction,friction interface noise strength by 8.5%,vibration acceleration amplitude reduced by 29.7%.For subsequent texture provide important reference to the research on the reliability of the rolling bearing.
