[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: As Figures 1-5 As shown, a bearing designed for use in high-temperature and corrosion-resistant environments includes an outer silicon nitride ceramic ring 1, an outer heat insulation layer 2 fixedly connected to the top of the outer silicon nitride ceramic ring 1, an outer rubber anti-corrosion layer 3 fixedly connected to the top of the outer heat insulation layer 2, a bearing ball 4 slidably connected to the inner wall of the outer silicon nitride ceramic ring 1, an inner silicon nitride ceramic ring 5 slidably connected to the outer wall of the bearing ball 4, an inner heat insulation layer 6 fixedly connected to the top of the inner silicon nitride ceramic ring 5, an inner rubber anti-corrosion layer 7 fixedly connected to the top of the inner heat insulation layer 6, and a spacer 8 slidably connected to the outer wall of the bearing ball 4. One side of the spacer 8 is movably connected to the inner wall of the outer silicon nitride ceramic ring 1, and the other side of the spacer 8 is movably connected to the outer wall of the inner silicon nitride ceramic ring 5.

[0027] First, the external equipment is fixed to the inner phase of the inner silicon nitride ceramic ring 5, and the outer wall of the outer silicon nitride ceramic ring 1 is locked to the outer wall phase. At this time, the rotation of the external equipment during operation causes the inner silicon nitride ceramic ring 5 to rotate, which also causes the bearing ball 4 to rotate around the inner silicon nitride ceramic ring 5. This prevents the outer silicon nitride ceramic ring 1 and its connected equipment from rotating. At the same time, the outer rubber anti-corrosion layer 3 and the inner rubber anti-corrosion layer 7 can prevent the bearing from being corroded. In addition, the inner silicon nitride ceramic ring 5 and the outer silicon nitride ceramic ring 1 have good heat resistance, and the outer heat insulation layer 2 and the inner heat insulation layer 6 can isolate some heat. Meanwhile, the protective rubber ring 9 can also provide protection for the bearing ball 4, so that the bearing can achieve the effect of high temperature resistance and corrosion resistance.

[0028] Example 2: Figures 1-5 As shown, a bearing designed for use in high-temperature and corrosion-resistant environments includes an inner silicon nitride ceramic ring 5 with a protective rubber ring 9 mounted on its outer wall. The diameter of the protective rubber ring 9 is smaller than that of the outer silicon nitride ceramic ring 1. Four mounting bolts 10 are inserted into one side of the outer silicon nitride ceramic ring 1. A block 11 is movably connected to the outer wall of the mounting bolts 10, and the thickness of the block 11 is smaller than that of the outer silicon nitride ceramic ring 1. Eight bearing balls 4 are slidably connected to the inner wall of the outer silicon nitride ceramic ring 1.

[0029] First, if it is necessary to disassemble the bearing, remove the mounting bolt 10 by turning it with a screwdriver. Then, the assembly block 11 can be pulled out. With the opening of the assembly block 11 facing downwards, the bearing ball 4 and the spacer block 8 will quickly separate from the bearing assembly, thereby achieving the effect of quickly disassembling the bearing and avoiding damage to other recyclable parts in the bearing during disassembly.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
