You can minimise misalignment by aligning after assembly. A lower misalignment in the
coupling has the following advantages:
• Reduced wear of the elastomer components
• 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 57).

Possible misalignment
The following types of misalignment can occur:

Angular misalignment (ΔKw)
③

Possible misalignment
5.3.2.1
Axial misalignment
Set the axial misalignment ΔKa to a value within the permissible tolerance range of dimension
S2.
You can find the values for dimension S2 in section Speeds, geometry data and weights
(Page 53).
5.3.2.2
Angular misalignment
Determine the value ΔS2 (ΔS2 = S2
max
- S2
min
). The determined value ΔS2 may not exceed the
value ΔS2
perm
.
You can find the values for ΔS2
perm
in section Shaft misalignment values during operation
(Page 57).
If required, you can calculate the angular misalignment ΔKw as follows:
ΔKw [rad] = ΔS2 / DA
