Thrust disc wobbles
Thread Content
Regarding the issue of the thrust plate swinging, the specific steps are as follows: divide the circumference into equal sections, then place a dial indicator on each side (making sure the distance from the indicator head to the center is the same). Subtract the reading from indicator 2 from the reading of indicator 1 (the question is: should one divide by 2?) ), the maximum value across the entire circumference is the swing value.

However, in most cases small rotors don’t move much, so installing one sensor is sufficient, though two sensors are even better. When there is a drift momentum, it needs to be subtracted; when there is no drift momentum, subtraction is not required. There’s no such thing as dividing by 2
Practical experience shows that when the rotational speed exceeds 2,000 revolutions, as long as there is no displacement, it will appear as a straight line on the DCS screen.
