Is there a standard length dimension for oil baffle rings?

[Sá]

There is no fixed standard length dimension for oil baffle rings. The working principle of oil baffle rings: 1. Centrifugal force: Oil baffle rings utilize the centrifugal force generated by rotation to fling oil back toward the oil return direction. Therefore, they should be inclined toward the oil return side, i.e., using a conical surface with the larger end facing the oil return direction. This requires determining their size based on the available space at the installation position. 2. Grease lubrication: Oil baffle rings are mainly used in gearboxes. Since large gears use oil bath lubrication, the meshing with small gears is lubricated through the splashing effect of the large gears. Rolling bearings typically use grease lubrication. To prevent the lubricating oil in the oil sump from being splashed into the rolling bearings and diluting the grease, which would reduce lubrication effectiveness, an oil baffle ring is added on the inner side of the bearing. Under axial positioning, the oil baffle ring rotates together with the drive gear shaft and the bearing inner ring.
