The invention belongs to the technical field of bearings and particularly provides an oil-control resistance-lowering cylindrical roller bearing. The oil-control resistance-lowering cylindrical rollerbearing comprises a bearing inner ring, a bearing outer ring and cylindrical rollers. The end face of an oil outputting end of the bearing inner ring is provided with a bearing gasket, the bearing gasket is connected with the bearing outer ring through an inner oil outputting ring and an outer oil outputting ring, the inner oil outputting ring rotates along with the bearing gasket, and the outeroil outputting ring rotates along with the bearing outer ring. The inner oil outputting ring and the outer oil outputting ring are uniformly provided with a plurality of oil outputting holes in the circumferential direction, and the bearing is in an oil outputting state when the hole positions of part of the oil outputting holes in the inner oil outputting ring and the outer oil outputting ring are overlapped. The oil inputting end of the bearing inner ring is sleeved with an inner oil resistance ring rotating along with the bearing inner ring, the oil inputting end of the bearing outer ring is internally provided with an outer oil resistance ring rotating along with the bearing outer ring, the inner oil resistance ring and the outer oil resistance ring are uniformly provided with a plurality of oil inputting holes in the circumferential direction, and the bearing is in an oil inputting state when the hole positions of part of the oil inputting holes in the inner oil resistance ring and the outer oil resistance ring are in an overlapped state. The oil-control resistance-lowering cylindrical roller bearing is simple in structure, and resistance generated when lubricating oil is stirred can be lowered.
Description
technical field [0001] The invention belongs to the technical field of bearings, in particular to an oil-controlling and drag-reducing cylindrical roller bearing. Background technique [0002] At present, among the cylindrical roller bearing products in the same industry, the bearing is completely open lubrication, and the lubricating oil enters the bearing to lubricate the rotating bearing, but the flow of lubricating oil cannot be controlled, which also produces a certain amount of stirring resistance to the bearing rotation . Foreign literature has verified that due to the resistance generated by lubrication and stirring, the influence on the rotational torque of the entire bearing reaches 30%. Therefore, if the bearing is in use, if the rotational torque is to be reduced, the stirring resistance of the lubricating oil must be reduced. Contents of the invention [0003] The object of the present invention is to provide an oil-controlling and drag-reducing cylindrical ...
