What factors will reduce the measurement accuracy of dynamic balancing machine

The factors of the dynamic balancing rotor, the dynamic balancing machine itself and the measuring system will lead to the dynamic balancing machine can not work normally or can not meet the requirements of the rotor dynamic balancing accuracy. Therefore, no matter which link is abnormal, it will affect the dynamic balance accuracy of the workpiece. If we can analyze these problems pertinently, we can correctly judge the causes of various situations, and then take effective measures to reduce or eliminate these factors. What is the relationship between tooling and dynamic balancing machine?? Now Xiaobian will introduce it to you.

1. The tooling is not made according to the requirements, and the radial jump and end jump of the matching surface between the tooling and the workpiece are poor, which leads to the difference between the rotation axis of the workpiece on the dynamic balancing machine and the actual rotation axis of the workpiece.

2. The workpiece deforms after cooling when welding balance weight.

3. Due to the lack of hardness of the workpiece itself, deformation occurs when the workpiece rotates at high speed, resulting in mass deviation or the workpiece itself has unfixed parts loose when it rotates.

4. The rotation direction of the work piece of the universal joint dynamic balancing machine should be the same as that of the spindle marked on the headstock spindle, and cannot be reversed（ If it needs to be calibrated again, the angle indicator needs to be replaced)

5. The quality factors of workpiece shaft diameter, circle runout and shaft diameter collision will make the signal unstable.

6. The rotor shaft is bent or circular runout, and the finish of the rotor shaft or the support frame of the dynamic balancing machine is poor.

7. The roller bearing ball is worn or the roller's outer circle smoothness and circular runout are poor (the roller's circular runout should be controlled within 1 thread).

8. The dynamic balancing machine of rolling bearing rotor is equipped with rolling bearing rotor. When balancing, it is better to balance with rolling bearing together, so as to eliminate the imbalance caused by eccentric inner ring of rolling bearing. The rotor with bearing is usually carried out on V-shaped support.

9. The jacking force of the axial stop frame is too large.
