7. The high temperature and corrosion resistant thrust cylindrical roller bearing according to claim 1, wherein: the cylindrical shell (402) is made of composite bearing steel, and the core (401) is made of composite carbonized steel.
8. A method for processing a high temperature and corrosion resistant thrust cylindrical roller bearing based on any one of claims 1 to 7, characterized in that: the method comprises the following steps:
step one: a groove (301) and a through hole A (2) are formed along the upper surface of the bottom plate (1), then the clamping plate (305) is placed in the groove (301) so as to carry out primary clamping connection between the clamping plate (305) and the inner side wall of the groove (301), and then the screw A (307) is rotated so as to carry out further detachable connection between the clamping plate (305) and the bottom plate (1);
step two: inserting a cylindrical shell (402) along the outer surface of the core body (401), completely wedging the outer surface of the core body (401) with the cylindrical shell (402), putting a cover plate A (404) along the opening end of the cylindrical shell (402), and rotating a screw C (403) so as to detachably connect the cover plate A (404) with the core body (401);
step three: placing the open end of the cylindrical shell (402) into the cover plate B (405) and rotating the screw D (406) so as to detachably connect the cover plate B (405) with the core body (401), and further fixing the core body (401) in the middle position of the cylindrical shell (402), thus assembling the cylindrical roller assembly (4);
step four: sequentially placing the assembled cylindrical roller assemblies (4) on the upper surface of the clamping plate (305), and covering the clamping ring (302) so as to preliminarily clamp the cylindrical roller assemblies (4) on the upper surface of the clamping plate (305);
step five: the fixing ring (303) is clamped along the slot (306), meanwhile, the upper surface of the clamping ring (302) is clamped, and then the fixing ring (303), the clamping ring (302) and the clamping plate (305) are detachably connected through the rotating screw B (304), so that the cylindrical roller assembly (4) is limited at the middle position of the clamping ring (302) and the clamping plate (305);
step six: an arc-shaped roller path (503) is formed on the upper surface of the ring body (501), the radian of the arc-shaped roller path (503) is based on the inclination of the upper surface of the cylindrical roller assembly (4), and a through hole B (502) with the same diameter as the through hole A (2) is formed on the inner wall of the bottom surface of the arc-shaped roller path (503), so that the processing of the whole thrust cylindrical roller bearing is completed.
