Precision Alignment

Duration 2 days

Precision alignment is one of the primary tools for maximizing the reliability of rotating machinery. Just
the smallest amount of angle or offset between two shafts will result in excess load on the bearings,
seals, shaft, and coupling. In addition, the vibration generated can result in accelerated failure of
other machine components and the supporting structure. It has also been demonstrated that
misaligned machines consume more energy.

The Topics Include

  • An overview of precision alignment
  • A detailed introduction including the reliability benefits
  • The basics of dial-indicator calculations
  • Rim-and-face and reverse-dial dial-indicator alignment overview
  • Pre-alignment checks
  • Soft foot detection and correction
  • The rim-and-face method in detail
  • The reverse-dial method in detail
  • Laser alignment methods in detail
  • Moving the machine (and how to deal with the bolt bound and base bound situations)
  • Dealing with dynamic and thermal growth
  • Machine train alignment
