① Axial misalignment (ΔKa)
② Angular misalignment (ΔKw)
③ Radial misalignment (ΔKr)
5.3.2.1 Axial misalignment
5.3 Aligning the coupling
Set the axial misalignment ΔKa to a value within the permissible tolerance range of dimen-
sion S2.
You can find the values for dimension S2 in section Speeds, geometry data and weights
(Page 55).
5.3.2.2 Angular misalignment
5.3 Aligning the coupling
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 59).
If required, you can calculate the angular misalignment ΔKw as follows:
ΔKw [rad] = ΔS2 / DA
ΔKw [deg] = (ΔS2 / DA) · (180 / π)
If required, you can calculate the permissible angular misalignment ΔKw
perm
as follows:
ΔKw
perm
[rad] = ΔS2
perm
/ DA
ΔKw
perm
[deg] = (ΔS2
perm
/ DA) • (180 / π)

5.3 Aligning the coupling
Determine the value ΔKr. The determined value ΔKr may not exceed the value ΔKr
