Abstract
Now, the most of lubrication methods of the ball 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 data about the behavior. It is possible to contribute to the performance gain of all ball bearings including making of it long-lived greatly if the behavior of grease in it can be clarified. In the present study, I produce the experimental device and can observe behavior of the grease in the bearing. I put a result next. (1) Some characteristics of the behavior of the grease including the scattering of the grease are confirmed. (2) It is confirmed for the connecting of the behavior of the grease , the temperature of a ball bearing and the rotating torque.
