Shaft­mounted Gear Unit With Flanged Coupling - Siemens FLENDER B3 E Series Assembly And Operating Instructions Manual

Fig. 53: Example of alignment on a flexible coupling
1 Ruler
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.
For gear units with hollow output shaft, the coupling on the output side is not required. Gear units with
hollow output shafts must be fitted on the shafts of the customer s machinery. Gear units with flanged
coupling must be fitted on the customer s shaft via a counterflange.
6.9 Shaft­mounted gear unit with flanged coupling
The front area of the flanged coupling must be absolutely free from 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.
The tightening torque of the flange bolts is shown in the drawings included in the
documentation of the coupling.
In order to avoid any distortion, it must be supported by a torque arm or a pedestal
(see items 6.11 and 6.12).
Under no circumstances may the gear unit be stressed.
