step two: inserting a cylindrical shell (402) along the outer surface of the core (401), completely wedging the outer surface of the core (401) and the cylindrical shell (402), placing a cover plate A (404) along the open end of the cylindrical shell (402) and rotating a screw C (403) so as to detachably connect the cover plate A (404) and the core (401);
step three: putting the open end of the cylindrical shell (402) into a cover plate B (405) and rotating a screw D (406) so as to detachably connect the cover plate B (405) and the core body (401), and further fixing the core body (401) at the middle position of the cylindrical shell (402), so that the cylindrical roller assembly (4) is assembled;
step four: the assembled cylindrical roller assembly (4) is sequentially placed on the upper surface of the clamping plate (305), and then the clamping ring (302) is covered, so that the cylindrical roller assembly (4) can be preliminarily clamped on the upper surface of the clamping plate (305);
step five: the fixing ring (303) is clamped along the slot (306), the upper surface of the clamping ring (302) is clamped at the same time, and the fixing ring (303), the clamping ring (302) and the clamping plate (305) can be detachably connected by rotating the screw B (304), so that the cylindrical roller assembly (4) is limited in the middle position of the clamping ring (302) and the clamping plate (305);
step six: an arc-shaped raceway (503) is formed on the upper surface of the ring body (501), the radian of the arc-shaped raceway (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 that of the through hole A (2) is formed in the inner wall of the bottom surface of the arc-shaped raceway (503), so that the whole thrust cylindrical roller bearing is machined.
