Auxiliary supporting device for improving stress of tooth part of stator core of large-scale generator and use method of auxiliary supporting device for improving stress of tooth part of stator core of large-scale generator

The invention relates to the technical field of hydro-generator repair, in particular to an auxiliary supporting device for improving stress of a tooth part of a stator core of a large-scale generator and a use method. An auxiliary supporting device for improving stress of a tooth portion of a stator iron core of a large generator comprises an auxiliary pressing finger, the auxiliary pressing finger is suitable for being arranged between an original pressing finger and broken teeth of the stator iron core or suitable for being arranged between the original pressing finger and a loose section iron core of the stator iron core, and the auxiliary pressing finger is fixedly connected with the original pressing finger. The auxiliary supporting device for improving the stress of the tooth part of the stator iron core of the large-scale generator and the using method solve the problems of tooth breakage, tooth part loosening, pressure finger eccentricity and the like of the stator iron core, and the defects of long
