[Journal: Lubrication (Vol. 8, No. 4, 1
963) ”describes the results of observing the grease behavior inside the bearing when the ball bearing with the seal incorporating the cage is grease-lubricated and the inner ring is rotated while the outer ring is stationary. The contents are as follows. "The flow of grease inside a bearing can be broadly divided into two flows, the main flow and the split flow. In the main flow, the grease moves between the raceway surfaces of the inner and outer rings via the rolling elements (while adhering to the rolling elements). The term “diversion” refers to the flow of grease not adhering to the rolling elements, the amount of the main flow being about 10% of the total amount of grease sealed in. The speed of the main flow is extremely high, mainly from the rolling elements. The grease moves from the main flow to the branch by the flow toward the vessel and the flow from the inner ring to the seal, and the grease from the inner ring to the seal adheres to the seal. With this rotation, the process from the transfer of the grease from the rolling element to the cage to the movement toward the outer raceway surface will be described with reference to FIG.

Next, as shown in FIG. 5D, the grease G is deposited in the form of a film on both end surfaces 21 of the flat portion 2 of the cage 10. Next, as shown in FIG. 5E, the grease G is blown toward the outer raceway while being broken by centrifugal force. Then, FIG.
The process shown in (e) is repeated. Therefore, the amount of grease supplied to the outer raceway surface is constantly changing. As a result, the lubrication state of the bearing becomes unstable, and torque fluctuation or vibration may occur in the bearing. It is also conceivable that an excessive amount of grease is present on the outer raceway surface. In this case, the grease life may be shortened due to the excessive amount of grease present on the outer raceway surface subjected to severe shearing force.
