An Experience With Nonstandard Coupling Application.
Abstract
The selection of flexible couplings is often considered to be routine because there are a variety of proven designs available. A compressor retrofit that required variance from standard coupling design practice is discussed, along with the problems that occurred, and how the problems were resolved. In the early 1980s, two new compressors with a drive turbine were retrofitted to an existing foundation. Marine type gear couplings were applied and have subsequently exhibited hub to shaft galling, fatigue failure of the rabbet pilot, abnormally rapid wear of the coupling teeth, and coupling bolt failure by hydrogen embrittlement. Changes to the existing design have helped, but the final solution will be installation of a different style coupling.
