[0021] Example: see figure 1 , figure 2 with image 3 As shown, a gear shaft of a new energy vehicle reducer includes a rod part and a disc part 1. The disc part 1 has a cylindrical structure and the outer wall is provided with a toothed structure 2. The rod part is vertically arranged at the center of the disc part The upper rod 3 and the lower rod 4 are respectively provided with an upper transition section 5 and a lower transition section 6 between the disk part and the upper rod 3 and the lower rod 4 of the rod part. The diameters of the upper and lower transition sections 5 and 6 are respectively larger than that of the upper rod 3. , The diameter of the lower rod 4, the lower rod 4 from the disc part to the bottom is a circular truncated cone structure with a decreasing diameter, the rod part and the disc part 1 are integral structures made of metal forging; through cutting processing in the gear shaft of the new energy vehicle reducer A penetrating central through hole 7...
