[0012] (1) The whole is composed of the first shaft head, flange, locating pin, roller, ceramic body, second shaft head and other parts. The first shaft head, roller and second shaft head are welded together and then precision turned, and then assembled. At this time, the locating pin passes through the flange into the ceramic body, and then fixed by a nut, so that the flange and the ceramic body become one. The hexagonal cylindrical end set screw in the flange can fix the flange on the roller, and the sleeve is fixed to the roller by two hexagonal flat end set screws. In this way, a whole is formed. When disassembly is required, the hexagonal cylindrical end set screw and the hexagonal flat end set screw on the roller are unscrewed, the roller is removed first, and then the hexagonal cylindrical end set screw, the hexagonal flat end set screw, the nut, etc. on the flange at the end of the second shaft head are unscrewed, and the flange, locating pin and ceramic body can be removed. In this way, the ceramic body can be easily replaced, which improves the convenience of actual use;

[0013] (2) By coating the waterproof layer on the outside of the ceramic body and coating the first wear-resistant layer on the outside of the waterproof layer, the wear resistance of the ceramic body is improved with the cooperation of the first wear-resistant layer and the waterproof layer. Therefore, during the disassembly and installation of the ceramic body, the surface wear is reduced. At the same time, a second wear-resistant layer is also coated on the inner wall of the flange to reduce the wear problem during the disassembly and installation of the flange.
