Embodiment 1
[0030] figure 1 It is a schematic diagram of the spline shaft before being repaired by a crankshaft repair method disclosed in the present invention. As shown in the figure, a crankshaft repair method of the present invention repairs the spline shaft. The repair steps are as follows:
[0031] (1) When milling the damaged part of the spline shaft, use a milling cutter to fix it, rotate the arc surface of the spline shaft, install a detachable rotating handle at the end of the spline shaft, and mill out the damaged part of the semicircular surface 1 of the spline shaft. Part of the semi-circular surface is arc groove-shaped, retaining the spring position of the spline shaft and the keyway 2; accurately grasping the arc surface of the shaft to be milled, controlling the damaged part of the shaft to be repaired, and avoiding the arc surface of the shaft to be milled by mistake. Wrong milling, improve accuracy;
[0032] (2) Support the bearing stands 3 at both ends of the spline s...
