    • Advances In Gas Turbine Couplings. 
      Corcoran, Joseph P.; Lyle, Douglas; McCormack, Patrick; Ortel, Tim (Texas A&M University. Turbomachinery Laboratories, 2007)
      Over the last 50 years industrial gas turbines have advanced significantly. Horsepower has increased 200 percent (and even higher) within the same envelope. Improvements in efficiencies and reliability (more operating time ...
    • The Baffling And Temperature Prediction Of Coupling Enclosures. 
      Carter, Donald; Garvey, Martin; Corcoran, Joseph P. (Texas A&M University. Turbomachinery Laboratories, 1994)
      Increasingly, turbomachinery users are setting upper limits on coupling enclosure temperatures. This is done either to protect personnel, to ensure the proper operating temperature for bearing oil that leaks past seals (or ...
    • Coupling Credible Failure Modes and Owner Options to Intervene 
      Locke, Stephen R.; Burgess, Michael J.; Corcoran, Joseph P.; Hess, Thomas D. (Texas A&M University. Turbomachinery Laboratories, 2013)
      While all machine component failures can impact reliability, cost and production, some like coupling failures may have safety risks for personnel. Intervention requires us to build appropriate steps into our machine and ...
    • Discovering, The Hard Way, How A High Performance Coupling Influenced The Critical Speeds And Bearing Loading Of An Overhung Radial Compressor - A Case History. 
      Corcoran, Joseph P.; Rea, Harvey; Cornejo, Guill A.; Leonhard, Martin L. (Texas A&M University. Turbomachinery Laboratories, 1997)
      A case is presented where significant unacceptable vibration levels were encountered during mechanical testing of a single stage overhung radial compressor used in a mechanical vapor recompression process. The contract ...
    • Is The Dry Coupling Really Causing Your Vibration Problem? 
      Cornejo, Guill A.; Corcoran, Joseph P.; Chen, Sujen (Texas A&M University. Turbomachinery Laboratories, 1995)
      From time to time vibration probes pick up high vibration at the coupling location on output shafts. Many times the coupling will then be removed and sent to the shop or to the manufacturer for inspection, repair, and ...
    • Preventing Undetected Train Torsional Oscillations 
      Corcoran, Joseph P.; Kocur, John A.; Mitsingas, Michael C. (Texas A&M University. Turbomachinery Laboratories, 2010)
      In the past few years the authors have encountered numerous problems and coupling failures related to unexpected torque fluctuations on applications with reciprocating compressors and on VFD, synchronous motor, and gas ...
    • Torsional Oscillation Trouble on VFD Motor Driven Recip Compressor 
      Corcoran, Joseph P.; Kocur, John A. (Texas A&M University. Turbomachinery Laboratories, 2008)
      High vibration problems including failed coupling parts on a VFD motor driven reciprocating compressor are analyzed and the root causes and solutions are discussed in this costly field issue.
    • VFD Induced Coupling Failure 
      Corcoran, Joseph P.; Kocur, John A. (Texas A&M University. Turbomachinery Laboratories, 2008)
      A catastrophic failure of a high performance disc coupling connecting the speed increaser and LP compressor in a VFD controlled 18,300 HP motor/speed increaser/LP compressor/HP compressor train, led to months of reduced ...
