DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 A corrosion-resistant bearing in this embodiment includes an outer ring 1 and an inner ring 2, and a protective mechanism is arranged inside the outer ring 1.

[0021] In this embodiment, the protection mechanism includes a first wear-resistant sleeve 3 fixedly connected to the outer ring 1, a second wear-resistant sleeve 4 is fixedly connected to the outside of the inner ring 2, and the inner ring 2 is movably installed inside the outer ring 1 to facilitate the rotation of the inner ring 2, reduce the load friction coefficient, and reduce the loss of driving force. A ball body 5 is movably installed on the side of the first wear-resistant sleeve 3 opposite to the second wear-resistant sleeve 4. The size of the first wear-resistant sleeve 3 is larger than that of the second wear-resistant sleeve 4. The second wear-resistant sleeve 4 is located inside the first wear-resistant sleeve 3. The first wear-resistant sleeve 3 and the second wear-resistant sleeve 4 are both made of silicon carbide material. Ceramics made of silicon carbide material have strength, hardness, and anti-friction ability, and can resist the influence of chemical substances. They are used to manufacture sealing rings. The ball body 5 is isolated from the outer ring 1 and the inner ring 2 by the first wear-resistant sleeve 3 and the second wear-resistant sleeve 4, reducing the wear of the outer ring 1 and the inner ring 2 and increasing the durability and corrosion resistance of the bearing.

[0022] Among them, the outer part of the outer ring 1 is sleeved with the first protective shell 6 and the second protective shell 7, the inner part of the inner ring 2 is provided with a mounting hole 12, and the opposite sides of the first protective shell 6 and the second protective shell 7 are provided with arc grooves adapted to the mounting hole 12, which facilitates the installation and connection between the inner ring 2 and the rotating shaft, and facilitates the installation and use of the bearing.

[0023] Among them, the left side of the second protective shell 7 is fixedly connected with a plug-in block 701 which is plugged into the first protective shell 6. A slot 601 is opened inside the first protective shell 6, and the plug-in block 701 is plugged into the first protective shell 6 through the slot 601. The first protective shell 6 and the second protective shell 7 are both stainless steel. Stainless steel is the abbreviation of stainless acid-resistant steel. Steel that is resistant to weak corrosive media such as air, steam, water, or has stainless properties is called stainless steel; and steel that is resistant to corrosion by chemical corrosive media is called acid-resistant steel, which facilitates the installation of the first protective shell 6 and the second protective shell 7, and enhances the corrosion resistance of the bearing through the first protective shell 6 and the second protective shell 7.

[0024] Among them, the first protective shell 6 and the second protective shell 7 are fixedly connected to the opposite side with a rubber sealing gasket 8. The molecular chains of the rubber can be cross-linked. When the cross-linked rubber is deformed by external force, it has the ability to recover quickly and has good physical and mechanical properties and chemical stability. Rubber is the basic raw material of the rubber industry and is widely used in the manufacture of tires, hoses, tapes, cables and various other rubber products. The rubber sealing gasket 8 is used to seal the joint between the first protective shell 6 and the second protective shell 7 to reduce the corrosion of external impurities and liquids entering the first protective shell 6 and the second protective shell 7 to the outer ring 1, the inner ring 2 and the ball body 5.

[0025] Among them, the interiors of the first protective shell 6 and the second protective shell 7 are both threadedly connected with fixing screws 9 threadedly connected to the outer ring 1, and a threaded hole 101 is provided inside the outer ring 1. The fixing screws 9 are threadedly connected to the outer ring 1 through the threaded hole 101, and the first protective shell 6 and the second protective shell 7 are limited and fixed, which is convenient for the installation and disassembly of the first protective shell 6 and the second protective shell 7, increases the stability of the installation connection of the first protective shell 6 and the second protective shell 7, reduces the loosening and falling off of the first protective shell 6 and the second protective shell 7 during the use and movement of the bearing, and improves the stability of the corrosion resistance function of the bearing. The side of the first protective shell 6 and the second protective shell 7 separated from each other is fixedly connected to the fixing block 10, and a fixing hole 11 is provided inside the fixing block 10. The user passes the fixing bolt through the fixing block 10 through the fixing hole 11, and uses the fixing bolt to fix the first protective shell 6 and the second protective shell 7, which is convenient for the installation and fixation of the bearing, the installation and disassembly of the bearing by the user, and the maintenance and replacement of the bearing.

[0026] The beneficial effects of the above embodiments are:

[0027] The corrosion-resistant bearing has enhanced corrosion resistance and wear resistance by providing a protective mechanism, reduces loosening and falling off of the outer ring body of the bearing, improves the stability of the corrosion resistance function of the bearing, and solves the problem that the first ring body and the second ring body are connected by connecting blocks and connecting holes without limiting and reinforcing, which may easily cause the first ring body and the second ring body to fall off during the use and movement of the bearing, thereby reducing the corrosion resistance of the bearing and affecting the stability of the bearing during use.

[0028] The working principle of the above embodiment is:

[0029] When the corrosion-resistant bearing is in use, the bearing is fixedly connected to the rotating shaft through the mounting hole 12, and the rotating shaft drives the inner ring 2 to rotate. The first wear-resistant sleeve 3 and the second wear-resistant sleeve 4 isolate the ball body 5 from the outer ring 1 and the inner ring 2 to reduce the wear of the outer ring 1 and the inner ring 2. At the same time, the first protective shell 6 and the second protective shell 7 seal and protect the outer ring 1, the inner ring 2 and the ball body 5 to reduce the corrosion of the outer ring 1, the inner ring 2 and the ball body 5 by external impurities and liquids. The rubber sealing gasket 8 seals the joint between the first protective shell 6 and the second protective shell 7, and the fixing screws 9 limit and reinforce the first protective shell 6 and the second protective shell 7, thereby reducing the loosening and falling off of the first protective shell 6 and the second protective shell 7 during use and movement and improving the stability of the corrosion resistance function of the bearing.
