Problems solved by technology

[0002] The existing shaft repair technology mainly adopts welding processing repair technology; for some shaft lengths (such as fan rotor shaft), conventional welding repair will cause bending deformation; and the bearing position is returned to the manufacturer for repair after wear, which takes a long period and high cost
Due to the large and long wear area and the wear depth reaches 2mm, the existing repair technology cannot guarantee that the shaft will not be bent and deformed, and cannot achieve rapid repair

Abstract

The invention belongs to the technical field of machinery, and relates to a shaft cold repair method, which adopts a rapid cold repair technology combining a precise cold welding technology and a polymer composite material repair technology, and is a rapid repair technology carried out under the condition of no cold welding and circumferential welding technology. By the adoption of the repairing technology, shaft abrasion can be rapidly repaired, the repairing quality can meet the production requirement, the repairing period is effectively shortened, the repairing cost is reduced, and the production benefit is improved.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a method for cold repairing shafts. Background technique [0002] The existing shaft repair technology mainly adopts welding processing repair technology; for some shaft lengths (such as fan rotor shaft), conventional welding repair will cause bending deformation; and the bearing position is returned to the manufacturer for repair after wear, which takes a long period and high cost. Due to the large and long wear area and the wear depth of 2mm, the existing repair technology cannot guarantee that the shaft will not be bent and deformed, and cannot achieve rapid repair. Contents of the invention [0003] In view of this, the object of the present invention is to provide a shaft cold repair method, which can ensure that the shaft does not undergo bending deformation, highlights the cold repair technology, and realizes rapid repair. [0004] In order to achieve the above object, t...
