The invention discloses a self-centering positioning structure of a crane wheel set bearing box, which comprises an adjusting semi-ring arranged on the crane wheel bearing box, the cross section of the adjusting semi-ring is in a right trapezoid shape, and the back surfaces of the right-angle sides of the adjusting semi-ring are respectively close to an end cover of the bearing box and an inner side flange of the bearing box. The bevel edges of the adjusting semi-rings face the portion, above the bearing box, of the trolley frame, the trolley frame has the self-centering characteristic under the action of the bevel edges of the adjusting semi-rings on the two sides, the height of the right-angle side L1 of the side face of the right trapezoid is 25 mm, the length of the top side L4 of the side face of the right trapezoid is 16 mm, and the length of the bottom side L2 of the side face of the right trapezoid is 27 mm. The height L3 of the end face, making contact with the trolley frame, of the right trapezoid is 8 mm.
