[0002] At present, the one-way thrust ball bearing is a separable bearing, which consists of a shaft ring, a seat ring, and a set of steel balls and cage components. It is easy to install and disassemble, and is only suitable for parts with low speed. This type of bearing can bear axial loads, but cannot bear radial loads. However, after using for a period of time, the existing one-way thrust ball bearing needs to add lubricating oil to the inside of the bearing. At this time, the bearing needs to be removed from the machine or the housing of the external machine needs to be disassembled, and then the lubricating oil needs to be applied and injected into the inside of the bearing so that the rolling element is fully in contact with the lubricating oil, and the maintenance of the bearing has been completed. This method of adding lubricating oil is relatively complicated and requires shutdown and disassembly, which is time-consuming and labor-intensive, resulting in low work efficiency.

[0005] The seat ring 1 and the shaft ring 2 are coaxially symmetrically arranged, and a retainer 3 is arranged between the seat ring 1 and the shaft ring 2. A rolling body 4 is arranged inside each pocket of the retainer 3. The lower surface of the seat ring 1 and the upper surface of the shaft ring 2 are respectively uniformly processed with n oil holes 5 along the circumferential direction, where n is a positive integer.

[0006] Furthermore, the oil hole 5 is divided into a vertical section and an inclined section, and the bottom end of the vertical section is connected to the top end of the inclined section;

[0007] Furthermore, the angle between the axis of the vertical section and the inclined section of the oil hole 5 is 110° to 180°;

[0008] Furthermore, the number of oil holes 5 on the lower surface of the seat ring 1 and the upper surface of the shaft ring 2 is the same;

[0009] Furthermore, the number of the oil holes 5 is n, 2≤n≤4;

[0010] Furthermore, the inner diameter of the shaft ring 2 is smaller than the inner diameter of the seat ring 1;

[0011] Furthermore, the lower surface of the seat ring 1 and the upper surface of the shaft ring 2 are respectively processed with an annular oil groove along the circumferential direction;

[0012] Furthermore, the annular oil groove is connected to the oil hole 5;

[0013] Furthermore, when in use, the one-way thrust ball bearing is a separable bearing, which is composed of a seat ring 1, a shaft ring 2, a cage 3 and a rolling element 4. It is very convenient to install and disassemble. It is only suitable for parts with low speed. This type of bearing can bear axial loads, but cannot bear radial loads. When the bearing is installed in a relatively closed space, it is difficult to manually disassemble the bearing, and the maintenance of the bearing is relatively difficult. At this time, the lubricating oil can be injected into the bearing through the oil hole 5 to make the lubrication effect of the raceway better. At the same time, the oil hole 5 is divided into a vertical section and an inclined section. The bottom end of the vertical section is connected to the top end of the inclined section, and a certain amount of lubricating oil can also be stored. When the lubricating oil is consumed to a certain extent, the lubricating oil in the oil hole 5 can be supplemented to a certain extent, thereby improving the service life of the bearing.

During the operation of the equipment, the lubricating oil can be injected into the bearing through the two annular oil grooves and the four oil holes; therefore, when the bearing is installed in a relatively closed space, there is no need to disassemble the bearing from the equipment, and the lubricating oil is injected into the bearing through the oil holes on the bearing, so that the lubrication effect of the raceway is better, thereby improving the work efficiency; at the same time, the oil hole is divided into a vertical section and an inclined section, and the bottom end of the vertical section is connected with the top end of the inclined section, and a certain amount of lubricating oil can also be stored. When the lubricating oil is consumed to a certain extent, the lubricating oil in the oil hole can be supplemented to a certain extent, thereby improving the service life of the bearing.

[0019] The seat ring 1 and the shaft ring 2 are coaxially symmetrically arranged, and a retainer 3 is arranged between the seat ring 1 and the shaft ring 2. A rolling body 4 is arranged inside each pocket of the retainer 3. The lower surface of the seat ring 1 and the upper surface of the shaft ring 2 are respectively uniformly processed with n oil holes 5 along the circumferential direction, where n is a positive integer.
