Possible misalignments
Misalignments of the coupling parts in relation to each other can be caused by inaccurate alignment during
assembly, but also by actual operation of the equipment (expansion due to heat, shaft deflection,
insufficiently rigid machine frames, etc.).
The following maximum permissible misalignments must by no means be exceeded
during operation.
6.5.1
Axial misalignment
Axial misalignment ΔKa (Fig. 10) of the coupling parts relative to one another is possible within the
"permissible deviation" for dimension "S" (see orderrelated title page).
6.5.2
Angular misalignment
The angular misalignment ΔKw (Fig. 10) can usefully be measured as the difference in the gap dimension
"S" (ΔS = S
max.
– S
min.
). For the permissible values for the difference in the gap dimension, refer to item
6.5.4.
If required, the permissible angular misalignment ΔKw can be calculated as follows:
