When the bearing is lubricated with grease, in order to prevent the grease from being washed out and diluted by the oil extruded when the gear is engaged in the box, the sealing oil plate should be set up in the bearing

When oil lubrication is used, if the diameter of the pinion tooth top circle beside the bearing is less than the outer diameter of the bearing, in order to prevent a large number of hot oil extruded from the gear meshing (especially when the helical gear meshing) into the bearing interior and increase the resistance of the bearing, the oil baffle plate is often set
