Many newcomers always feel that the process of correcting the rotor dynamic balance is not very smooth when correcting the rotor dynamic balance. In fact, these are all an experience problem. Today, I will talk about some of the tips I have summarized and I hope that everyone will support me. Articles, sharing and collections.

We use the last rotor to illustrate the balancing process:
a =2.110 b =0.450 c =2.150 center distance =1.755 speed =400 tolerance range ≤ 10g

Idling: 1.23Kg 120 ° 1.41 Kg 165 ° (Now idling, understand the rotor imbalance, and then do the compensation for the first run)

Run one: 1.22 Kg 122 ° 1.41 Kg 162 ° (turn the rotor 180° and then run for the second time)

Run two: 1.72 Kg 310 ° 1.63 Kg 356 ° (accept the compensation value after two runs)

Initial unbalance: 1.53 Kg 301 ° 1.49 Kg 348 °

After getting the initial unbalance, we based on the data on the rotor and the result is:
(1) 132g 287 ° 145g 359 °
We moved the clip to: 294 ° and 352 ° and then changed 1.53 Kg and 1.49 Kg to 1.90 Kg and 1.80 Kg respectively.

(2) The result of the rotation is: 32g 220 ° 19g 33 ° We have the angle shown by the computer as the benchmark, the method of the upper clamp to find the best position of the rotor with the focus. If we find the best position we can match the weight on the rotor. Last time 32g and 19g at 287° and 359 ° are the best positions. Because we changed the hooks several times, but they were always larger than 32g and 19g, so we soldered things at 287° and 359 °. The standard unbalance of this rotor, we calculated the standard unbalance range is ≤ 15g, obviously our last two data can not meet the requirements, so we have two points 287 and 359 as the benchmark to find the second best balance point Finally, we found the 203° and 343° two spot welds with an unbalance of 8.3g and 6.7g respectively. Obviously these two data are within 15g, and our balance has reached the standard.

Then: the process of balancing the rotor is to find the position of the counterweight in the rotation of the rotor under the condition of compensation, and adjust the unbalance to the standard requirement.

The above is the detailed operation process of the rotor dynamic balance brought to you by Xiaobian. I hope that everyone can help.
