Vibration parameters:

  1. Coupling Imbalance
  2. Non-parallel Coupling Faces
  3. Coupling Wear
  4. Misaligned 3-jaw Coupling
  5. Locked Gear Flex Coupling


  1. Incorrect assembly, key fitted incorrectly, excessive lubrication in a gear coupling, etc …
  2. Parallel misalignment in the coupling.
  3. Conditions make the coupling wear out at a faster rate.
  4. Too much misalignment or a wrong choice of coupling.
  5. Severe wear on hub and teeth of a gear coupling or poor lubrication.
