• Reduced restoring forces
• Misalignment reserves for operation of the coupling
You can find the maximum permitted shaft misalignment values during operation in section
Shaft misalignment values during operation (Page 74).

Possible misalignment
5.3 Aligning the coupling
The following types of misalignment can occur:
ෙ.D
ෙ.Z
ෙ.U
Figure 5-5:
Possible misalignment
①
Axial misalignment (ΔKa)
②
Angular misalignment (ΔKw)
③
Radial misalignment (ΔKr)
Procedure for alignment
You align the flange couplings starting with the coupling half on the shaft-side and working
towards one of the machined surfaces of the motor flywheel or motor enclosure.
For shaft couplings, you determine angular and radial misalignment between the coupling
halves by measuring with a dial gauge.
5.3.2.1
Axial misalignment
5.3 Aligning the coupling
Set the gap ΔKa to a value within the permissible tolerance range of dimension S / LG / A.
The values for the dimension S / LG / A can be found in Geometry data and weights
(Page 63).
5.3.2.2
Angular misalignment
5.3 Aligning the coupling
Determine the value ΔKw. The determined value ΔKw must not exceed the value ΔKw
perm
.
You will find the permissible angular misalignment ΔKw
perm
in section Shaft misalignment val-
ues during operation (Page 74).
5.3.2.3
Radial misalignment
5.3 Aligning the coupling
Determine the value ΔKr. The determined value ΔKr may not exceed the value ΔKr
perm
.
You will find the permissible radial misalignment ΔKr
perm
in section Shaft misalignment values
