[0028] The effect achieved by the whole embodiment 1 is that when installing the combined motor main shaft disc mounting structure, the worker needs to first sleeve the spline sleeve 7 along the outer surface of the main shaft 2 until the outer surface of the spline sleeve 7 is in close contact with the outer surface of the fifth fixed block 5, at this time the inner part of the spline sleeve 7 is in close contact with the outer surface of the main shaft 2 and the fourth fixed block 4, the fourth fixed block 4 and the inner part of the spline sleeve 7 are connected by interference fit, interference fit is a mechanical fit method, which means that the size of the internal and external fitting parts has a certain interference during assembly, that is, the size of the external part is larger than that of the internal part, which is a known technology and will not be explained in detail. Then the worker moves the main shaft disc 10, which will drive the fixed assembly 3 to move, until the gear disc 301 is sleeved into the outer surface of the main shaft 2, the inner part of the gear disc 301 is engaged with the outer surface of the spline sleeve 7, at this time the inner part of the gear disc 301 is in close contact with the outer surface of the fifth fixed block 5, a plurality of first round holes 302 and a plurality of second round holes 6 are one-to-one corresponding, then the worker slides the pin 303 into the inner part of the first round hole 302, and then slides into the inner part of the second round hole 6 through the inner part of the first round hole 302.
