Abstract

The invention discloses a motor rotor correcting dynamic balance by a de-weighting method. The motor rotor comprises a rotating shaft (1), a fastening nut (2), a stop washer (3), a first de-weight ring (4), a rotor core (5) and a second de-weight ring (6); the features are that the first de-weight ring (4) and the second de-weight ring (6) are respectively arranged on the end surfaces of the two sides of the rotor core; the other end of the first de-weight ring is fixed on the rotating shaft through the stop washer and the fastening nut, and the other end of the second de-weight ring is matched with the end face of a step part on the rotating shaft, or the other end of the second de-weight ring is also fixed on the rotating shaft through the stop washer and the fastening nut. According tothe invention, balance amount correction is convenient, mounting/dismounting is convenient, balance amount fixing parts do not exist, the mounting space is saved, safety and reliability are achieved,and the rotating speed adaptability of the motor can be remarkably improved.

Description

technical field [0001] The invention relates to the field of motor rotors, in particular to a motor rotor whose dynamic balance is corrected by a de-weighting method. Background technique [0002] In order to reduce the noise and vibration index of the motor, the motor rotor needs to correct the dynamic balance. As the motor speed increases, the requirements for the unbalance of the motor rotor also increase. [0003] At present, there are several ways to correct the dynamic balance of the motor: For conventional motors, the dynamic balance of the motor rotor is corrected by drilling a counterweight in the front of the motor and adding a balance ring counterweight at the rear end of the motor. Bolt fixing: For motors with high speed, due to the consideration of the reliability of the motor rotor, bolts cannot be used to simply fix the counterweight balance, which is easy to fall off. Usually, dovetail slots are added to the fan at the front end of the motor and dovetail slot...
