Fig. 58: Example of alignment on a flexible coupling

The maximum permissible misalignment values are specified in the operating
instructions for the coupling; they must under no circumstances be exceeded
during operation.
Angular and radial misalignments may occur at the same time. The sum of both
misalignments must not exceed the maximum permissible value of the angular
or radial misalignment.
If you use couplings manufactured by other manufacturers, ask these
manufacturers which alignment errors are permissible, stating the radial loads
occurring.
For alignment of the drive components (vertical direction), it is recommended to use
packing or foil plates underneath the mounting feet. The use of claws with set screws on
the foundation for lateral adjustment of the drive components is also advantageous.
In the case of gear units with hollow output shafts or flange output shafts, the coupling on the output side
is not required. Gear units with hollow output shafts must be mounted on the shafts of the customer’s
machinery. Gear units with flanged output shafts must be mounted on the customer’s shaft via
a counterflange.
6.9 Shaft­mounting gear unit with flanged shaft
The front area of the flanged shaft must be absolutely free of grease.
This is essential for safe and reliable torque transmission. Do not use
contaminated solvents or dirty cloths for removing grease.
Before tightening the tensioning bolts it must be ensured that the flange
centring means are inserted one inside the other.
Then tighten diametrically opposed tensioning bolts to full torque.
