Embodiment 1

[0015] A repair method after a drive shaft breaks, such as figure 1 and figure 2 shown, the axis of rotation dimensions mm x 4000 mm, minor axis size mm x 900 mm. Rotary axis machining center hole mm, the short axis and the central hole of the rotating shaft adopt an interference fit.

[0016] The repair method after the above-mentioned transmission shaft is broken is as follows:

[0017] Machining the center hole 3 in one end section of the disconnected drive shaft 1, install the short shaft 2 in the center hole 3, adopt a large interference fit between the center hole 3 and the short shaft 2, and then carry out surfacing welding on the outside of the short shaft 2, and surfacing welding to the transmission After the original size of the shaft, finish machining according to the drawings to restore the mechanical properties of the drive shaft. The repaired drive shaft is as follows: image 3 shown.

Abstract

The invention discloses a method for repairing a fractured transmission shaft. The method comprises the steps that 1, after the transmission shaft (1) is fractured, a center hole (3) is machined in the fracture surface of the fractured end of the transmission shaft (1), a short shaft (2) is installed in the center hole (3), and the center hole (3) is in large interference fit with the short shaft (2); 2, build-up welding is conducted on the outer side of the short shaft, finish machining is conducted after the size of the short shaft is identical with the original size of the transmission shaft (1) through build-up welding, and then a repaired transmission shaft is obtained. By the adoption of the method, the repairing effect is quite good, investment is quite low during repairing, and repairing time is quite short.

Description

technical field [0001] The invention belongs to the field of mechanical maintenance, and in particular, the invention relates to a repair method for a broken transmission shaft. Background technique [0002] In the field of mechanical maintenance, many transmission shafts cannot be repaired after they are broken. At present, there is no good repair method. It needs to be scrapped and remade into a new transmission shaft, causing a lot of waste. Contents of the invention [0003] The object of the present invention is to provide a repair method for a broken transmission shaft, which has better repair effect, less investment in repair and shorter repair period, and overcomes the current problem that the broken drive shaft cannot be repaired. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is as follows: [0005] A method for repairing a broken transmission shaft, said method comprising the following steps: [0006] 1) Af...
