Description
Technical Field
The utility model relates to the technical field of high-speed motors, in particular to a high-speed motor rolling bearing.
Background
Rolling bearings are used to reduce friction by rolling cylinders, rolling balls or rolling cones and are converted into axial and radial loads. The high-speed motor is internally provided with a rolling bearing. In the process of high-speed running of the motor, the rolling bearing can generate a large amount of heat due to friction, if the rolling bearing is not cooled in time, the bearing can be damaged due to high temperature, and therefore, the cooling of the rolling bearing in the high-speed motor is a critical ring, and the temperature of the bearing needs to be reduced through heat dissipation measures. The cooling mode of the bearing at present mainly comprises air cooling, water cooling heat exchange, grease lubrication and oil gas lubrication, and most of the rolling bearings of the high-speed motor only adopt the oil gas lubrication mode because of the over-high speed and large heating value, however, most of the oil gas lubrication systems of the bearings on the market are more complex in structure and easy to block.
Disclosure of Invention

The technical problems solved by the utility model can be realized by adopting the following technical scheme: the utility model provides a high-speed motor antifriction bearing, includes motor end cover, antifriction bearing, spacer ring and casing, all there are oil inlet and oil return opening on motor end cover and the spacer ring, the oil return opening that motor end cover was last is located motor end cover inner circle bottom and passes through motor casing surface connection oil station oil tank, and the oil inlet that motor end cover was last is located motor end cover outer lane top and passes through the export that the pipeline connects the oil pump motor, and the import of oil pump motor connects the oil station oil tank, the clearance between antifriction bearing and motor end cover, spacer ring and the casing is antifriction bearing's inside oil circuit.
The upper part of the oil inlet is provided with a Y-shaped filter valve, so that contaminated oil is prevented from entering the bearing to be blocked.
The outer end of the rolling bearing is provided with a labyrinth type oil seal.
An oil inlet on the spacer is formed in the radial direction of the spacer, an oil return port on the spacer is positioned on the end face of the oil return port pointing to the bearing, and the oil inlet on the spacer is larger than an opening of the oil return port on the spacer.
Compared with the traditional high-speed motor rolling bearing, the high-speed motor rolling bearing has the advantages that: the structure is simple, the temperature of the bearing can be effectively reduced, the bearing can reliably operate for a long time, and the bearing can keep relatively stable temperature in the process of high-speed operation, so that the bearing can reliably operate for a long time.
