Coupling

Couplings transfer torques in rotating systems

Couplings transfer torques in rotating systems. This type of power transfer is ever-present in
production and processing industries. Many different types of couplings are used:

  • Rigid
  • Flexible
  • Torsionally elastic
  • Universal shaft couplings, etc.


Insufficient servicing and inaccurate alignment of couplings can result in the following problems:

  • Damage to the machinery and production losses due to downtimes
  • Efficiency losses, i.e. increased power consumption
  • Increased wear of bearings and seals
  • Leakage, overheating, vibrations, or even inferior product quality.


Modern laser-optical coupling alignment methods from PRUFTECHNK offer higher precision and
easier operation compared with conventional methods such as thickness gages,
straightedges and dial gages.
