The invention relates to an aperture repairing method, in particular to an emergency aperture repairing method. An emergency aperture bonding and repairing method comprises the following steps: burr and cinch marks on the aperture surface are repaired and ground, and the whole surface is scuffed by rubber; the opposite edges are evened by a sample punching pin on the aperture surface; the actual size of the aperture after wearing is measured respectively, points are taken in the inner diameter of the aperture on both sides of the vertical center line of the aperture by 45 degrees above and below, and the actual size of the aperture after wearing is measured by an internal micrometer; half of the difference between the standard aperture and the actually measured data is taken as the thickness of a brass sheet lining board required by a single edge; then the brass lining board is cut into strips according to that one fifth of the width of a bearing seat is taken as the width, three times of the width is taken as the length, and the corresponding position of the brass lining board is marked; and the aperture position is entirely cleaned by a cleanser so that no burr and sundries are remained on the inner surface of the aperture. The method can ensure that all indexes which are measured during the running of the repairing device reach the original design requirements of the devicewithin the shortest time and with the least manpower and material resources.
