Experimental studies on rolling-element bearing lubrication represent an ambitious engineering challenge. In the present study, the design of a dedicated test rig to perform Particle Image Velocimetry (PIV) measurements on the lubricant inside a tapered roller bearing is presented. Through the usage of a sapphire outer ring, it has been possible to optically access the inside of a bearing without compromising its kinematics. PIV measurements allowed the reconstruction of the lubricant velocity field in the cavity between the cage and the outer ring at different rotational speeds. Results show that as the speed of rotation increases, bubbles due to aeration phenomena tend to appear and modify the behavior of the lubricant considerably.

外圈由蓝宝石制成的圆锥滚子轴承内的粒子图像测速测量:创新测试台的设计和操作

滚动轴承润滑的实验研究是一项艰巨的工程挑战。在本研究中,介绍了对圆锥滚子轴承内的润滑剂进行粒子图像测速 (PIV) 测量的专用测试台的设计。通过使用蓝宝石外圈,可以在不影响其运动学的情况下以光学方式进入轴承内部。PIV 测量允许在不同转速下重建保持架和外圈之间的腔中的润滑剂速度场。结果表明,随着旋转速度的增加,由于充气现象往往会出现气泡并显着改变润滑剂的行为。
