Typically, a motor manufacturer will set a thrust bearing for load bearing and a spindle guide bearing on top of the motor. The assembly modes of the two are different, and the corresponding lubrication and cooling modes are different. The guide bearing is arranged below the thrust bearing and is provided with an independent lubrication and cooling system (generally grease lubrication and natural cooling); the thrust bearing is arranged above and is usually arranged in an oil pool, adopts a thin oil lubrication mode, and directly exchanges heat with the outside by virtue of a heat dissipation rib plate welded on the outer surface of the oil pool. In the bearing assembly structure, the guide bearing is generally positioned in the motor shell, and if the bearing needs to be replaced, the upper thrust bearing part can be removed completely, so that the workload is high.

The bottom of the thrust bearing seat 2 is provided with a plurality of radial rectangular grooves, so that lubricating oil can form a circulating oil path, the lubricating oil can circulate, the circulating path of the lubricating oil is prolonged, the cooling effect is improved, and the uniformity of the oil is maintained; the arrangement direction of the oil blocking blades 802 in the oil blocking radials 8 is opposite to the rotation direction of the motor, and the oil blocking blades 802 and the inner circle tangential direction of the oil blocking radials 8 form an acute angle, so that the oil can splash towards the direction close to the rotating shaft when the oil tangentially flows along the rotating shaft; the number of the oil blocking blades 802 is six, and the oil blocking blades are uniformly distributed on the annular plate 801 in an array manner, so that the distribution uniformity of lubricating oil can be improved, and a consistent cooling effect is maintained; the oil tank body 1 is of a welding tube 803-shaped structure, and a plurality of radiating rib plates are arranged on the surface of the oil tank body, so that the radiating effect of lubricating oil can be improved, and meanwhile, the oil tank body 1 can be used as a top end cover of a motor; the thrust bearing seat 2 and the bearing are in interference fit, and are integrally fixed on the end cover at the bottom of the oil pool body 1 after being assembled in place, so that the phenomenon of abrasion acceleration caused by too tight assembly and too high friction can be avoided; the oil sump body 1 and the oil level indicator 10 are communicated through the pipeline, so that the oil level of lubricating oil in the oil sump body 1 can be displayed through the oil level indicator 10, and the operator can check conveniently.
The specific working principle of the invention is as follows: the novel structure abandons the type that the original thrust bearing and the guide bearing are independently lubricated, and innovatively shares a set of lubricating oil system, because the guide bearing mainly plays a guiding role and basically does not bear load, the guide bearing is basically in an idling state in the running process of the motor, and the heat productivity is very small, so that the cooling of the guide bearing can be satisfied by means of natural cooling of the surface of a metal part contacted with the guide bearing, and meanwhile, when the motor runs, the rotating shaft rotates to drive lubricating oil to flow, so that the lubricating oil impacts on the oil blocking radial plate at a certain approach angle, and part of thin oil splashes onto the guide bearing above, thereby achieving the effect of lubricating the guide bearing.
