[0029] Please refer again Figure 1-4 The outer wall of the bearing inner ring 200 is provided with a first raceway 210, and the first raceway 210 is used to limit the bearing balls. The bearing inner ring 200 is located in the inner cavity of the inner ring 300, and the bearing inner ring 200 is used to cooperate with the bearing balls to support the bearing outer ring 100;

[0030] Please refer again Figure 1-4 A second raceway 310 is provided in the middle of the inner wall of the inner ring 300, and the second raceway 310 is used to limit the bearing ball. An annular groove 320 is provided on the inner wall of the second raceway 310, and the annular groove 320 is used to provide an installation space for the oil suction ring 330. The inner wall of the annular groove 320 is fixedly connected with the oil suction ring 330, and the outer wall of the oil suction ring 330 is fixedly connected with the oil suction rod 340 on both sides, and the oil suction rod 340 is distributed in an annular shape, and the oil suction rod 340 passes through the annular groove 320. The inner wall of the inner ring 300 extends to the outside of the inner ring 300. The oil suction ring 330 is used to cooperate with the oil suction rod 340 to absorb the lubricating oil flowing out of the first mounting ring 110 and the second mounting ring 130, and smear it on the bearing ball when it comes into contact with the bearing ball. An extension ring 350 is fixedly connected in the middle of the outer wall of the inner ring 300. The extension ring 350 is used to support the positioning ring 360. The inner ring 300 is located in the inner cavity of the bearing outer ring 100, and the inner ring 300 is used to support the bearing outer ring 100.

[0031] Please refer again Figure 1-4 Bolts 140 are threadedly connected between the front side wall of the second mounting ring 130 and the inner cavity of the threaded hole 120, and the bolts 140 are distributed in a ring shape. The bolts 140 are used to cooperate with the threaded hole 120 to fix the first mounting ring 110 and the second mounting ring 130.

[0032] Please refer again Figure 1-4 The oil suction rod 340 and the oil suction ring 330 are made of polypropylene material. The oil suction rod 340 and the oil suction ring 330 made of polypropylene material have high oil absorption.

[0033] Please refer again Figure 1-4The front and rear side walls of the extension ring 350 are fixedly connected with a positioning ring 360, and the positioning ring 360 is slidably connected between the inner cavities of the first mounting ring 110 and the second mounting ring 130. The positioning ring 360 can cooperate with the extension ring 350 to facilitate the rotation of the inner ring 300.

[0034] Please refer again Figure 1-4 The inner wall of the positioning ring 360 is provided with a positioning groove 370 , and the positioning groove 370 is distributed in a ring shape, and the positioning groove 370 can provide an installation space for the sliding ball 380 .

[0035] Please refer again Figure 1-4 The inner cavity of the positioning groove 370 is slidably connected with a sliding ball 380, and the sliding ball 380 is made of stainless steel. The sliding ball 380 made of stainless steel has high strength and provides convenience for the sliding of the positioning ring 360.

[0036] To summarize, by providing a positioning ring 360, the first mounting ring 110 and the second mounting ring 130 can be rotated, and at the same time, the sliding ball 380 can be used to improve the rotation efficiency. When the inner ring 300 is driven to rotate in contact with the bearing balls inside the first raceway 210 inside the second raceway 310, it can be rotated with the help of the extension ring 350 and the positioning ring 360, thereby reducing the friction between the bearing balls and the inner wall of the second raceway 310, making it less likely to wear, having high wear resistance, and improving the use efficiency of the bearing rings.

[0037] To summarize, the lubricating oil is additionally stored in the internal space provided by the first mounting ring 110 and the second mounting ring 130, and then is discharged through the connection gap between the extension ring 350 and the first mounting ring 110 and the second mounting ring 130, and is introduced into the oil suction ring 330 for storage through the oil suction rod 340. After the bearing balls are driven into contact with the oil suction ring 330, the lubricating oil can be applied to the bearing balls, so that the bearing rings have an additional oil storage mechanism, which increases the interval time for replenishing the lubricating oil in the bearing rings and facilitates use.

[0038] In specific use, the technical personnel in this field first place the positioning ring 360 and the sliding ball 380 in the first mounting ring 110, and fill the first mounting ring 110 with lubricating oil, then insert the second mounting ring 130, and then use a tool to dock the bolt 140 with the corresponding threaded hole 120 to complete the installation of the second mounting ring 130, and then install the bearing ball in the first raceway 210 and the second raceway 310, and then rotate the inner ring 300 to drive the lubricating oil through the first mounting ring 110 and the second mounting ring 130. The connecting gap of the ring 130 is guided out and absorbed by the oil suction rod 340 and introduced into the oil suction ring 330 for storage, and then the bearing inner ring 200 is rotated to drive the bearing balls and the oil suction ring 330, so that the lubricating oil absorbed by the oil suction ring 330 is smeared on the bearing balls. At the same time, the friction force generated when the bearing balls roll inside the second raceway 310 pushes the inner ring 300, driving the inner ring 300 to rotate in coordination with the extension ring 350, the positioning ring 360 and the sliding ball 380, thereby reducing the friction between the inner wall of the second raceway 310 and the bearing balls.
