Installing The Couplings - Siemens KMS Assembly And Operating Instructions Manual

• Flush out pipes thoroughly with water (H
• After emptying the pipes, they must be filled with a neutralising solution (sodium lye 3 % to 5 % NaOH)
(neutralisation period 15 minutes). Flush out pipes once again with water (H
• Flush out pipes thoroughly with flushing oil through a 25 μm (0.001 inch) filter.
NOTICE
Property damage
Damage from corrosion.
If the adapted pipes are not installed straight away, they must be carefully preserved.
If the preserved pipework is reinstalled, item 6.5 has to be observed.

Installing the couplings

A flexible coupling is used for the gear unit output.
Before beginning the assembly, thoroughly clean shaft ends and the coupling parts.
Fit couplings on the shaft ends using the thread centring hole. Secure the couplings against being shifted
axially.
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
Property damage
Damage in the gear unit from blows or impact is possible.
Fit the coupling with the aid of suitable fitting equipment.
The running surfaces of the shaft must not be damaged when pulling on in the coupling parts.
NOTICE
Property damage
Damage to the gear unit or individual components is possible from inadequate alignment.
When installing the drives, make absolutely certain that the individual components are accurately
aligned to one other. Unacceptable large errors in the alignment of the shaft ends to be connected due
to angular and/or axial misalignments result in premature wear and material damage.
Note
For permissible alignment errors in couplings supplied by Siemens, refer to the instructions manuals
for the couplings.
When using couplings manufactured by other manufacturers, ask these manufacturers which
alignment errors are permissible, stating the radial loads occurring.
