[0023] like Figure 1-4As shown, the bearing ring 1 includes a ring groove 2 on the outer wall of the bearing ring 1, an oil injection hole 3 is provided in the ring groove 2, an annular oil guide channel 6 is provided inside the bearing ring 1, and the inner wall of the bearing ring 1 is provided with divided holes 5 at equal intervals. An oil leakage prevention structure 4 is installed in the oil injection hole 3, and the oil leakage prevention structure 4 includes a plug hole 7, a limit ring 8, an oil outlet hole 9, a limit column 10, a sealing gasket 11, an oil drain hole 12, a guide groove 13, a guide rod 14, a pressure The limit column 10 is located in the oil filling hole 3, the outer wall of the limit column 10 and the oil filling hole 3 are plugged, the sealing gasket 11, the limit block 16, the guide rod 14 and the compression spring 15 are all located in the annular oil guide channel 6, the number of the guide rod 14, the guide groove 13 and the oil-draining hole 12 are two groups, the oil outlet hole 9 is opened on the outer surface of one side of the limit column 10, the jack 7 is opened in the middle of the outer surface of one end of the limit column 10, and the limit The ring 8 is fixedly mounted on one end of the jack 7 close to the oil outlet hole 9, and one end of the jack 7 is connected to the oil outlet hole 9; the outer surface of one end of the limit column 10 away from the jack 7 is fixedly connected to the middle of the outer surface of one side of the sealing gasket 11, and the sealing gasket 11 is fixedly mounted on the outer surface of one side of the limit block 16, and two groups of oil-repelling holes 12 are opened on the left and right sides of the outer surface of the other side of the limit block 16, and the two groups of oil-repelling holes 12 are opened on the outer surfaces of both ends of the limit block 16, and one end of the oil-repelling holes 12 is connected to the guide groove 13; the compression spring 15 is fixedly mounted between the middle part of the outer surface of one side of the limit block 16 away from the sealing gasket 11 and one side of the annular oil guide channel 6; the two groups of guide rods 14 are located on the left and right sides of the compression spring 15, and the outer surface of one end of the guide rod 14 is fixedly connected to one side of the annular oil guide channel 6, and one end of the guide rod 14 extends into the guide groove 13, and the outer wall of the guide rod 14 is slidably connected to the guide groove 13.

[0024] One end of the oil filling hole 3 is communicated with the annular oil guide channel 6 , and one end of the branch hole 5 is communicated with the annular oil guide channel 6 .

[0025] It should be noted that the utility model is a high-lubrication and oil-leakage-proof bearing ring assembly, which is provided with an oil-leakage-proof structure 4. When an oil injection needle is needed to add lubricating oil to the inside of the bearing ring 1, one end of the oil injection needle is inserted into the insertion hole 7, and the oil injection needle is limited by the limiting ring 8. The oil injection needle squeezes the limiting column 10, so that the limiting column 10 is separated from the oil injection hole 3. The limiting column 10 drives the limiting block 16 to squeeze the compression spring 15. Through the provided guide rod 14 and guide groove 13, the limiting block 16 slides along the outer wall of the guide rod 14 through the guide groove 13, thereby improving the stability of the limit column 10 and avoiding the limit column 10 from deflecting after being separated from the oil injection hole 3. It is difficult to reset, and the extrusion limit column 10 drives the oil outlet hole 9 to enter the interior of the annular oil guide channel 6 to start oil filling. The lubricating oil enters the annular oil guide channel 6 through the oil outlet hole 9 and is finally discharged through the branch hole 5. After the oil filling is completed, the oil filling needle is pulled out. Due to the reset effect of the compression spring 15, the limit column 10 is reset, and the limit column 10 enters the oil filling hole 3. The sealing gasket 11 blocks one end of the oil filling hole 3 to prevent the lubricating oil from flowing out through the position of the oil filling hole 3; the oil-draining hole 12 is set, and when the guide rod 14 slides along the guide groove 13, the lubricating oil entering the guide groove 13 can be squeezed out to avoid affecting the normal relative movement of the guide rod 14 along the guide groove 13.
