The reasons for the unstable measurement values of a single sided vertical balancing machine are complex and can be summarized in the following five aspects:
1. The rotor shaft is bent or has circular runout, and the smoothness is out of tolerance.
2. The roller bearing ball is worn or the smoothness and runout of the outer circle of the roller are out of tolerance.
3. Excessive jacking force of axial stop frame
4. The transmission rod of the vibration sensor is loose or the vibration is obstructed.
5. The vibration sensor cable plug or socket is loose, causing the signal to be blocked (the resistance of the sensor is about 4K, and the input impedance of the electrical measurement box is 70K).
There are many factors that can cause the balancing machine to malfunction or fail to achieve balance accuracy. Some of these factors are caused by the workpiece being balanced, while others are caused by the machine itself or the electrical measurement system. Therefore, as long as a certain link is abnormal, it will inevitably affect the balance of the workpiece. If we can analyze these phenomena in a targeted manner, it can help us correctly distinguish and determine the causes of various situations, and then take effective measures to reduce or eliminate the impact of these adverse factors on the balance of the workpiece.
