Synchronized dual rotors system inside and outside rotor unbalance value quick recognizing methods

Abstract

The invention discloses a method for quickly identifying unbalanced quantities of inner and outer rotors of a synchronous double rotor system. Method: 1) Install a reference signal sensor on the inner and outer rotors, and install a vibration sensor on the outer rotor; 2) Add marking lines in any circumferential direction of the inner and outer rotors, and mark the angle in the circumferential direction, and make the 0° line of the inner and outer rotors coincide; 3) Change the connection mode of the transition flange in the differential to make synchronous rotation; 4) Obtain the combined unbalance amount  by twice adding weight on the outer rotor; 5) Shut down, and then use the It rotates synchronously, and obtains  left by twice adding weight on the outer rotor; 6) obtains left inner, α, M left outer, and β of the left correction surface; 7) obtains the respective imbalances of the right correction surface in the same way; 8 ) on the opposite side of the unbalance of the left and right correction planes, the obtained unbalance is installed, and the balance of the whole machine is completed. The invention effectively solves the difficult problem that the inner rotor cannot obtain the reference signal, avoids the disadvantage of needing to test and aggravate, greatly reduces the balancing time, and improves the balancing 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...

AI Technical Summary

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.
