The angle of inclination of the output flange, as a function of the tilting moment acting on the output bearing, can be
calculated by means of equation 45.1:

7.3.4 Angle of Inclination
with:
γ
[arcmin]
= Angle of inclination of the output flange
M [Nm]
= Tilting moment acting on the output bearing
K
B
[Nm/arcmin] = Moment stiffness of the output bearing

7.3.3 Permissible Static Tilting Moment
In case of static load, the bearing load capacity can be determined as follows:
f
s
= Static load safety factor
(f

= Static equivalent load
d
p
= Pitch circle diameter of the output bearing
M = Moment acting
M
