摘　　要：设计制造了推力滚子轴承光干涉润滑油膜测试系统,以滚子与玻璃盘多点接触代替传统的球-盘单点接触方式,并采用多光束干涉技术对不同载荷下的线接触润滑油膜特性进行了初步测量。分析了轴承滚子膜厚建立的过程以及滚子素线上不同位置膜厚随速度的变化情况。结果表明:随载荷增加,接触区增大,膜厚降低,弹流特征明显;随着速度的增大,在相同载荷固定位置处油膜厚度增大。The measuring system is designed and manufactured for lubricating oil film of thrust roller bearings. The traditional ball-on-disc single point contact method is replaced by roller and glass disc multi-point contact method,and preliminary measurement for characteristics of line contact lubricating oil film under different loads are carried out by using multi-beam interferometric technology. The variations of film thickness with speed at different locations of roller generatrix are analyzed. The results show that the contact area enlarges and film thickness reduces with increase of load. Finally,the EHL characteristics are more obvious. Moreover,the oil film thickness increases with speed at fixed position under same load.
