Effect of Pore Parameters on Lubrication Performance of Oil-Containing Cage

Under oil-free lubrication conditions, oil-containing cage becomes the only oil storage unit for bearing lubrication in aerospace equipment, therefore the performance of oil-containing cage directly determines the running state and operation life of rolling bearing. By X-ray CT technology, three-dimensional reconstruction analysis of cage microporous structure was carried out. And the image segmentation method based a level set function was employed to characterize the pore parameters and micropore structure of the cage. Finally, operating temperature of bearing cage was monitored via quantum dots temperature sensor, which is an on-line and non-contact test method. Based on the theoretical and experimental analysis, the lubrication performance of the oil-containing cage was evaluated.
