April 6, 2020, 1:07 a.m.Two-plane balancing is most often carried out using calculations in specialized programs. The task is to determine the sensitivity to test weights in both balancing planes and calculate the corrective weights. But in this article I want to highlight one of the methods of dynamic two-plane balancing of a rigid inter-bearing rotor without using programs. I am sure it will seem at least interesting to many experts. As always, with a real practical example at the place of operation. A fan of a double-sided suction in a belt drive (n = 3000 rpm) will act as a test subject.

In this article I want to talk about the difficulties encountered during vibration adjustment, the interweaving of many different defects at the rotational speed, the search for solutions to the problem, and the possibilities of the vibration adjustment specialist are not unlimited. A story without a happy ending, as always from our own real practice.
