[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example

[0024] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a corrosion-resistant bearing ring proposed in an embodiment of the present invention includes a bearing ring body 1, an annular block 2 is installed on the upper end of the bearing ring body 1, a sealing assembly 4 is provided on the annular block 2, and four groups of oil filling holes 5 are opened on the outer wall of the bearing ring body 1; through the four oil filling holes 5, it is convenient to lubricate the inside of the bearing ring body 1 with oil, reduce friction and wear, and increase service life, so that the lubricating oil is fully and evenly injected into the inside of the bearing ring body 1, thereby improving the use effect, and after the oil filling is completed, oil leakage can be avoided, and dust and impurities are prevented from entering the bearing body 1, further improving the use effect.

[0025] like Figure 3 、 Figure 4 As shown, in some embodiments, the sealing assembly 4 includes four annular holes 41 opened on the outer wall of the annular block 2, and sliders 42 are slidably connected in the four annular holes 41, and springs 47 are installed at both ends of the four sliders 42. Baffles 43 are installed on the outer walls of the four sliders 42, and fixing rods 44 are installed on the upper ends of the four sliders 42. The upper ends of the four fixing rods 44 are commonly connected to a grip ring 45, and a group of springs 47 are connected to the annular block 2; through the grip hole 46, the grip ring 45 is gripped to drive the fixing rod 44 and the slider 42 to slide in the annular hole 41, and squeeze the spring 47 on one side, and the spring 47 on the other side is stretched, thereby driving the baffle 43 to disengage from the oil filling hole 5, and oil filling on all four sides can be carried out. After the oil filling is completed, as the spring 47 resets, the baffle 43 blocks the oil filling hole 5 again to prevent dust from entering and oil leakage.

[0026] like Figure 4 As shown, in some embodiments, a group of grip holes 46 are provided on the grip ring 45 to facilitate operation.

[0027] like Figure 1 As shown, in some embodiments, the baffle 43 is in contact with the outer wall of the bearing ring body 1, so as to facilitate blocking the oil filling hole 5 and avoid oil leakage.

[0028] like Figure 3 As shown, in some embodiments, the cross section of the slider 42 is L-shaped, which is convenient for positioning.

[0029] like Figure 1 As shown, in some embodiments, the outer surface of the bearing ring body 1 is evenly sprayed with anti-rust oil. This anti-rust oil has excellent resistance to moisture, heat, and salt spray, providing excellent rust protection for metals. It also exhibits excellent resistance to human sweat corrosion and overlap resistance, ensuring a long-lasting and stable rust prevention effect. Furthermore, this oil has a high cleanliness rating, with a production filtration accuracy of less than 5μm. This prevents clogging of the automatic circulation spraying equipment used for lubricating bearing products, effectively maintaining the cleanliness and lubrication requirements of the oiled product. Therefore, spraying anti-rust oil can significantly improve the corrosion resistance of the bearing rings and extend their service life.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
