The invention discloses a shaft regeneration process. The shaft regeneration process includes the following steps that S1, a broken shaft is pre repaired, and a result is shown in figure 2, it is ensured that magnitude of interference exists between a hole D1 and a shaft diameter D2; S2, the hole D1 is cleaned, and all burrs are polished; S3, the same material as a shaft 1 is selected, and a shaft3 is machined, and the result is shown in figure 3; S4, the same material as the shaft 1 is selected, a pin shaft 1 is machined, and the result is shown in figure 4; and S5, a shaft 2 is heated to expand the shaft hole D1 to a diameter D1 being greater than D2, then the shaft 3 is installed in the shaft 2, and the result is shown in figure 5. According to the shaft regeneration process, comparedwith a traditional process that a direct welding method is adopted to connect the broken shaft, cracks are prone to happening, and the service life after repair is short, the service life of using theinterference assembly and
