AI Technical Summary

Problems solved by technology

The weighting method is suitable for rotors of various specifications; however, the balance mud pasted on the rotor is easy to fall off due to the centrifugal force of the rotor's high-speed rotation, and often needs to be reworked or has quality problems.

Abstract

The invention discloses a skewed-slot type balance ring rotor structure and a balance manufacturing method therefor. The structure comprises a rotating shaft, a rotor iron core, a rotor balance ring,a check ring, and a screw. The external surface of the rotating shaft is in interference fitting with the rotor iron core, and the rotor balance ring is in interference fitting with the external surface of an end part of the rotating shaft. The external surface of the rotor balance ring is provided with a skewed slot in a circle, and the inner wall of the skewed slot is provided with a plurality of tooth-shaped grooves, and is an inclined surface. The external surface of the rotor balance ring is provided with a plurality of first threaded holes, and the surface of the check ring is provided with a second threaded hole cooperating with the first threaded hole. The check ring is installed on the rotor balance ring through the screw, and the interior of the skewed slot is used for the pasting of balance mud. The structure can achieve the effective fixing of the balance mud, and the balance mud is not liable to fall off. Moreover, the structure is simple in processing technology, can achieve the de-weight operation of the dynamic balancing amount of the rotor, and also can achieve the weight operation of the dynamic balancing amount of the rotor.

Description

technical field [0001] The invention relates to the field of electromechanical technology, in particular to a skewed groove type balancing ring rotor structure and a balancing manufacturing method thereof. Background technique [0002] The dynamic balance of the servo motor rotor is a key indicator to determine the vibration and noise generated when the motor is running. One of the existing rotor dynamic balances is achieved by weight removal, and the other is achieved by weight gain. The weight-removing method is generally suitable for rotors with smaller specifications or less unbalance. This method has higher requirements for the processing and assembly of rotor parts. The weighting method is suitable for rotors of various specifications; however, the balance mud pasted on the rotor is easy to fall off due to the centrifugal force of the rotor's high-speed rotation, and often requires rework or has quality problems. Contents of the invention [0003] The technical pro...
