5.3.2.1 Axial misalignment
Set the axial misalignment ΔKa to a value within the permissible tolerance range of dimension
S.
You can find the values for dimension S in section Speeds, geometry data and weights
(Page 57).
5.3.2.2 Angular misalignment
Determine the value ΔS (ΔS = S
max
- S
min
). The determined value ΔS may not exceed the value
ΔS
perm
.
You can find the values for ΔS
perm
in section Shaft misalignment values during operation
(Page 62).
If required, you can calculate the angular misalignment ΔKw as follows:
ΔKw [rad] = ΔS / DA
ΔKw [deg] = (ΔS / DA) · (180 / π)
If required, you can calculate the permissible angular misalignment ΔKw
perm
as follows:
ΔKw

[rad] = ΔS
