MPTA C3c – Balancing Primer – (MPTA-C3c-2010)

Many users of elastomeric couplings are being presented with the need for increased balancing. This subject is mentioned in trade articles, trade shows, seminars, by consultants and engineering schools. The reason often given for increased coupling balance is noise, shaft and bearing wear, and vibration. Many of the proponents of tighter balancing speak of values of balance which can significantly increase the product cost and may produce no observable benefit to the application. All manufactured couplings have balance to some value or class. The amount of balance required varies from application to application. This is a result of the fact that every coupling is but one component of a rotating system of many components manufactured by several manufactures. It is often the characteristics of these other components which determine the amount of required coupling balance. Very often, the user of couplings specifies a value of balance based upon a source which has no knowledge of their unique system. The risk is that the value of balance specified may be beyond the user‘s application needs. Because the responsibility for the selection of proper coupling balance lies primarily with the purchaser of the coupling, this “primer” was written to aid that user in determining the value or class of balance needed in their own unique application.
