Counterweight gasket 4 is fixed on counterweight column 3, and the size of counterweight gasket 4, weight, shape equal-specification are consistent.
The shaft 2 of rotor is designed with keyway 21 in general shaft 2, if directly when being attached with other components
It connects and does dynamic balancing measurement with the rotor, since the presence of keyway 21 causes the rotor uneven, influence dynamic balancing survey
Test result, to overcome the problems, such as this, the utility model devises the counterweight balancing mechanism 5 cooperated with shaft 2, for offsetting keyway 21
Caused imbalance.The counterweight balancing mechanism 5 includes the counterweight ring 51 being adapted to shaft 2 and the clump weight being adapted to keyway 21
52, clump weight 52 is arranged on the inner ring of counterweight ring 51.Counterweight ring 51 is socketed in shaft 2, and counterweight ring 51 is connected to keyway
In 21；The length of clump weight 52 is equal to the length of keyway 21, and the height of clump weight 52 is equal to the depth of keyway 21, in counterweight ring 51
Circle is bonded with shaft 2.Go to expect solve and put down as caused by keyway 21 when clump weight 52 processes keyway 21 for compensating just
Weighing apparatus problem.
When correcting the balance of rotor with dynamic balancing machine, first according to keyway 21 on the motor rotor shaft to be corrected
Specification manufactures counterweight balancing mechanism 5 matched with its, then counterweight balancing mechanism 5 is mounted in shaft, i.e. 51 sets of counterweight ring
It connects in shaft 2, counterweight ring 51 is connected in keyway 21, imbalance caused by keyway 21 can be offset in this way, in visible model
Enclosing interior rotor is balance, and the influence by other factors to electric machinery rotator balance is preferably minimized.
Rotor after installation counterweight balancing mechanism 5 is put on dynamic balancing machine and carries out balance correction, specific steps are as follows:
A. trial correction reference phase first can be marked in rotor tip setting, and inputs dynamic balancing control system；It b. then will be to be measured
Examination rotor is placed in the test station of the automatic positioning balancing machine with digital display function, and starting device carries out dynamic balancing survey
Examination, equipment will be automatically stopped after test obtains phase to be corrected and quality to be adjusted, and show phase to be corrected over the display
Position and quality to be adjusted；The phase to be corrected and quality to be adjusted shown according to display in step b, using weightening finish method by described
Adjustment Mass Calculation goes out at phase to be corrected the number for needing addition counterweight gasket 4, this certain degree can also be defeated by parameter
Enter and directly calculated and shown by the control system of dynamic balancing equipment, continues correction until the comprehensive all balances of rotor are
Only, that is, rotor dynamic balance calibration operation is completed, sampling observation test verifying can also be carried out to calibration result certainly.Due to strictly pressing
Phase and quality according to weight gain carry out increasing counterweight gasket, so the rotor unbalance value after the method correction can level off to
Zero.
The utility model is exemplarily described in conjunction with attached drawing above, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as using the improvement for the various unsubstantialities that technical solutions of the utility model carry out, or without changing
Directly apply to other occasions by the conception and technical scheme of the utility model, the protection scope of the utility model it
It is interior.
