Title:
METHOD FOR DEFORMATION CORRECTION AFTER HEAT TREATMENT OF THIN-WALL GEAR RING PART
Document Type and Number:
WIPO Patent Application WO/2021/120391
Kind Code:
A1
Abstract:
A method for deformation correction after heat treatment of thin-wall gear ring part. A caliper is used to locate deformation points twice, and finally high-accuracy measurement is realized by means of a displacement sensor, thereby improving the correction accuracy. Different heat treatment processes are used with regard to the temperature of a flame gun and different circumferential sections of a part so as to avoid the problem of secondary deformation, thereby prolonging the service life of the part, and preventing the phenomena of deformation and scrapping of a thin-wall gear ring after heat treatment on the basis of controlling the processing cost such that same is not increased.
