| dc.description.abstract | Flexible couplings are too often thought of as a piece of hardware rather than a vital parts of power transmission systems. Virtually every user has a story about a piece of equipment with a coupling problem. Sometimes the coupling is the villain and just will not perform as needed, but often the coupling is only reacting to a concealed problem and shoulders the blame for the real culprit. The basics of coupling design and operation will be presented. This presentation is intended to help the equipment user and OEM better understand the purpose of a coupling, how it accomplishes those tasks, how to best specify and utilize flexible couplings, and how to locate the real causes of coupling problems.
Some of the issues discussed will be why use a flexible coupling, basic principles and terms, the differences between gear and flexible element couplings, selecting couplings for new applications, retrofitting gear couplings with flexible element couplings, and API Standard 671. Operating considerations will also be addressed, such as the rotordynamic effects of couplings, dynamic balance, installation procedures, maintenance considerations, and windage effects. | en |
