Abstract
This paper will discuss the unexpected high vibration seen on both the drive end and the driven end of a high-speed disc pack design coupling, in addition to the documented vibration at the coupling spacer mid-span location. The coupling was being used during the test stand mechanical verification runs of a high-speed centrifugal compressor to connect the compressor to a test gear which was driven by a test steam turbine. This paper provides the test results and the analysis procedure used to understand the vibration levels and dismiss the concerns for a journal bearing driven thermal instability at the compressor driven end bearing and at the adjacent pinion end bearing of the gearbox. A background history of coupling applications and previous relevant experience is given. Test results are given to confirm the solution of the problem, which was to reduce the length of the coupling spacer.
