The elements must be pulled smartly onto the shaft as far as stated in the dimensioned drawing prepared
in accordance with the order.
Fit the coupling with the aid of suitable fitting equipment. The parts must not be driven
on by abrupt force, as this may damage the gear unit.
The shaftsealing rings and running surfaces of the shaft must not be damaged when
pulling in the coupling parts.
When installing the drives, make absolutely certain that the individual components are
accurately aligned in relation to each other. Inadmissibly large errors in the alignment
of the shaft ends to be connected due to angular and/or axial misalignments result in
premature wear and/or material damage.
Insufficiently rigid base frames or substructures can also during operation cause
a radial and/or axial misalignment, which cannot be measured when the unit is at
a standstill.
Gear units whose weight requires the use of lifting gear must be attached at the points shown
in section 4, "Transport and storage".
If the gear unit is to be transported with addon parts, additional attachment points may be
required. The position of these attachment points is shown in the orderrelated dimensioned
drawing.
6.3.2.1 Alignment
The final fine alignment with the assemblies on the in and output side must be carried out accurately by
the shaft axes, using:
•
rulers
•
spirit level
•
dial gauge
•
feeler gauge, etc.
Only then should the gear unit be fastened and then the alignment should be checked once again.
•
Record alignment dimensions.
The record must be kept with these instructions.
The accuracy of shaft axis alignment is an important factor in determining the life span
of shafts, bearings and couplings. If possible, the deviation should be zero
(exception: ZAPEX couplings). For amongst others the special requirements for the
couplings, refer to the specific operating instructions.
Nonobservance can cause shaft rupture, resulting in serious injury and danger of life.
