Static deflection (mm)
To select correct mounting, following
data are needed:
1) Load per mounting (kg)
2) Interfering frequency (Hz)
(Hz = rpm / 60 )
Select correct load line in diagram 1 and
correct interference line in diagram 3.
The load line intersects with required type
of mounting.
Connect this intersection point vertically
down to the interference line in diagram 3.
Here, on the sloping curve, the isolation
degree is indicated.
For static deflection, see diagram 2.
