Coupling misalignment spectrum

WebThe main types of misalignment are angular, radial, and axial displacement. Factors that influence misalignment include thermal imbalances, wear, settlement and creep, and the … WebThe clunk may not show up too well in the spectrum but will be in the twf. ... 2X with 1X in an axial direction and many more scenarios depending on the degree and type of misalignment. In addition, a coupling may lock at relatively light loads and free itself up at high load but still transmit bending moments to the connected shafting.

Can coupling misalignment cause vibration?
