Principle and method of dynamic balance test

Rotary parts of the dynamic balancing machine, through the optional two correction plane to increase or reduce a certain amount of mass, so that the quality of the workpiece to re-distribution of the mass distribution of the center and the rotary axis coincidence, eliminate the unbalanced mass produced by centrifugal force and its couple.

The dynamic balance of the rotating body is completed on the dynamic balance test machine. There are many kinds of industrial dynamic balancing machines, but their composition and working principle are basically the same.

When the unbalanced workpiece is installed on the support and rotated, the workpiece and the support will generate vibration. The vibration signal is picked up by the sensor installed on the support and sent to the tester together with the reference signal generated by the reference signal generator.

The vibration signal generated by the sensor is a sinusoidal signal, and its amplitude reflects the magnitude of the unbalance that causes vibration.

The signal is processed and calculated by the tester, and the processing results are outputed-the size and position of the unbalance in the two correction planes.

The corresponding mass is removed or added in two calibration planes according to the test results, so that the mass of the workpiece is redistributed, so that the resultant centrifugal force and force couple generated by each mass are equal to or less than the allowable value, so that the workpiece reaches the dynamic balance.

Balance the instance

1. Install the rotor, and the belt winding method is shown in the figure;

2. After the power switch is switched on or the "exit" button is pressed, the measuring instrument enters the self-test process and everything is normal, the indicating panel will show Bal--20H
