6.8 Couplings, clutches
As a rule, flexible couplings or safety slip clutches are used for driving the gear unit.
If rigid couplings or other in and/or output elements, which create additional radial and/or axial forces,
(e.g. gear wheels, disk flywheels, hydraulic couplings) are to be used, this must be agreed by contract.
Note
Couplings must be balanced in accordance with the specifications in the pertinent instructions manual.
When operating and servicing the couplings, observe the operating instructions relating to the couplings.
Increased system service life and reliability and reduced running noise can be achieved through the least
possible radial and angular misalignment.
NOTICE
Material damage
Risk of damage to the gear unit or single components through incorrect alignment.
When positioning the drive units the instructions for the alignment of the individual components given in
the manuals belonging to the components must be observed.
Inadmissibly large errors in the alignment of the shaft ends to be connected through angular and/or axial
misalignments result in premature wear and material damage.
When using toothed couplings a defined alignment deviation may be required; observe the manual to
the toothed coupling.
Insufficiently rigid base frames or substructures can also during operation cause a radial and/or axial
misalignment, which cannot be measured when the unit is at a standstill.
Note
For permissible alignment errors in case of couplings supplied by Siemens, refer to the operating
instructions for the couplings.
When using couplings manufactured by other manufacturers, ask these manufacturers which alignment
errors are permissible, stating the radial loads occurring.
