Grease behavior observation of a ball bearing

Abstract

Now, the most of lubrication methods of the bearing is grease one. However, the grease cannot participate in lubrication when scattered in a bearing so that fluidity is small in comparison with the lubricating oil. In addition, there is the performance investigation example of grease in itself to date, but there are few date about the behavior. Then, in the present study, I produce the experimental device and can observe behavior of the grease in the bearing. I put below a result. I grasped a tendency of the scattering of the grease and correlation with the temperature of the inner circle of bearing.
