Manufacturers' World Of Coupling Potential Unbalance

LecturePg. 97-104Coupling balance is important to vibration free operation of turbomachinery. Understanding how and what in a coupling affects vibration is the purpose of this paper. Discussed are the basics of balancing, why a coupling is balanced, what contributes to unbalance in a coupling, how to bring a coupling into balance, when to balance a coupling and to what level, coupling balance limits, the arbitrary balance criteria, and the various types of coupling balance
