Description

Correction equipment for motor rotor rotating shaft runout Technical Field The utility model belongs to the technical field of motor rotating shaft correction, and particularly relates to correction equipment for motor rotor rotating shaft runout. Background The tight fit press-in of the motor shaft and the rotor is a common assembly technique, which fixes the shaft on the rotor by interference fit. The tight fit press-in can enable the rotating shaft to be in closer connection with the rotor, relative movement between the rotating shaft and the rotor is reduced, and therefore stability and durability of the motor are improved. At present, in the process of tightly matching the rotating shaft with the rotor, as one end of the rotating shaft is longer, the rotating shaft is often deformed after assembly (as shown in fig. 6), so that radial/axial runout of the rotating shaft exceeds standard, and the operation after the subsequent motor assembly is damaged, so that the bending deformation of the rotating shaft is necessary after the rotor enters the shaft. The current correction compression position is mainly at the rotor excircle, namely the rotor excircle is pressed down to realize correction (as shown in fig. 7), the rotor runout can be corrected, but the rotor runout can be increased, and the current correction tool mainly adopts a horizontal pressing mode, so that labor is not saved in the pressing process, the efficiency is low, and the improvement space is still provided.
