SHAFT COUPLINGS AND THE CINDERELLA SYNDROME

Shaft couplings tend to be the poor relation of the power plant family. They represent a relatively small investment compared to the complete drive train but their contribution to its viability is vital. When prime mover and driven machinery are coupled together they form a drive system and dynamic forces are unleased which may be many times greater than the forces generated by the individual machines. In practice it is the shaft couplings which must control these forces because the main machinery is already built, or nearing completion before the system analyses are made. To illustrate the versatility of shaft couplings with regard to the problems described, four drives have been selected for consideration: Diesel-Marine Propulsion; Turbo-Compressor; Steel Rolling Mill; and Synchronous Motor Drives.
