Other Info.
Flexible couplings transmit torque and rotational angle while absorbing misalignment. When the misalignment exceeds allowable values, vibration may result or the life of the coupling may become shortened. Make sure to adjust the alignment accordingly.
There are three types of shaft misalignment, namely in terms of parallel misalignment, angular misalignment and shaft end-play. Adjust the alignment to be below allowable values listed in the specification table of each miniature coupling. The maximum misalignment listed within this range is the allowable value only when one of the misalignments exists. In case two or more misalignments exist at the same time, the allowable values will be less than 50% of the maximum misalignment listed in the specification tables. Misalignments are sometimes caused not only by equipment assembly, but also by vibration, heat expansion, wear of bearings, etc during operation. Therefore, it is recommended to adjust the shaft misalignment to be below 1/3 of maximum values.
IMPORTANT:- Couplings and other rotational parts should be protected by covers for safety operation. Also, take note that operation under misalignment exceeding maximum values and excessive torque may result in shorter life of the coupling due to plastic deformation.
