Problems solved by technology

Due to the special inner and outer rotor sleeve structure of the double rotor, it is difficult to ensure the assembly accuracy, which is obviously reduced under the actual support conditions.
In addition, the wear and deformation of the rotor during operation will also produce new imbalances.

Embodiment Construction

[0037] The method for quickly identifying the unbalance of inner and outer rotors in a synchronous dual rotor system includes the following steps:

[0038] 1) Install the reference signal sensor on the inner and outer rotors respectively, and install the vibration measuring sensor on the outer rotor;

[0039] 2) Add a marking line at any circumferential position of the inner and outer rotors, and mark the angle in the circumferential direction, and make the inner and outer rotors 0 0 line overlap;

[0040] 3) Disengage the differential, change the connection mode of the transition flange in the differential, so that the inner and outer rotors rotate synchronously;

[0041] 4) Through two weight tests on the outer rotor, use the influence coefficient method to obtain the combined unbalance

[0042] 5) Stop and stagger the inner and outer rotors by α 0 Angle, then make it rotate synchronously, use the influence coefficient method, and obtain it by adding weight twice on the...

Abstract

The invention discloses a fast recognition method for the unbalance amount of internal and external rotors of a synchronous double-rotor system and includes that 1) the internal and the external rotors are provided with a reference signal sensor and the external rotor is provided with a vibration detecting sensor; 2) a marked line is added on any random circumferential direction of the internal and the external rotors, the circumferential direction is marked with angles and the lines of 0 degree of the internal and the external rotors are coincident; 3) the connecting mode of a transfer flange in a differential mechanism is changed to lead to rotating synchronously; 4) unbalance amount M is obtained by test weighing for twice on the external rotor; 5) a machine is stopped, after the internal and the external rotors are staggered at an angle of Alpha 0, the machine is led to rotate synchronously again and M' left is obtained by test weighting for twice on the external rotor; 6) M left inner, Alpha, M left outer and Beta of a left regulating surface are obtained; 7) each unbalance amount of a right regulating surface is obtained in a similar way; 8) the obtained unbalance amount is arranged on the opposite surface of the unbalance amount of the left and the right regulating surfaces to finish the balance of the whole machine. The invention effectively solves the difficulty that the internal rotor can not get a reference signal, avoids the defect of needing test weighting, reduces the balance time in large scale and improves the balance efficiency.

Description

technical field [0001] The invention relates to a method for quickly identifying unbalanced quantities of inner and outer rotors of a synchronous double rotor system. Background technique [0002] The invention belongs to the dynamic balancing technology of rotating parts. Specifically, it relates to a dynamic balancing method for a dual rotor system. [0003] During production and use, the dual-rotor system has been troubled by beating vibration caused by imbalance, which seriously affects the service life of the unit and the surrounding working environment. During the production process of the double rotor, only the inner rotor and the outer rotor are individually balanced on the dynamic balancing machine. After the complete machine assembly is completed, the complete machine is no longer balanced due to the lack of corresponding balancing equipment. Due to the special inner and outer rotor sleeve structure of the double rotor, it is difficult to ensure the assembly accu...
