When to use vibration absorbing feet

In case in a machine frequent "vibrations or shocks" occur, it will be necessary to use vibration absorbing feet instead of our standard feet. Because of the natural characteristics of the rubber elements, the selection of the proper type is very important. In a certain range of vibrations or shocks a resonance will occur, in another range of vibrations the feet will not absorb any vibrations at all. It is therefore important to follow exactly our selection procedure. Selection procedure.
 
Selection procedure

1) Calculation of the load on each foot
In the following formula we have considered that the weight of the machine is divided equally over the feet :
Weight of the machine (Kg)  = (Kgf)
Number of feet

2) Selection of the type of vibration absorbing foot -Table 1
The selection of the type of a vibration absorbing foot depends on the load on each foot and the lowest number of revolutions (or number of shocks) of the machine.
 
Examples of selection
1) Support for a lathe
Given data:-
-
-		 Weight of the lathe :2200Kg.
Minimum speed :140 rpm.
Quantity of feet :4.
Selection : the load on each foot is
 
2200
  = 550 Kgf

According to table 1 Part. 702 should be taken
1) Support for a metal press
Given data:-
-
-		 Weight of the lathe :3900Kg.
Minimum speed :120 strokes/min.
Quantity of feet :6.
Selection : the load on each foot is
  3900  = 650 Kgf

According to table 1 Part. 702 should be taken.
Mounting instructions
A) Lift the machine. Position the footplate. B) Mount the adjustment bolt with the nut and washer. C) By turning the adjustment bolt further, the support plate will lift until the desidered height has been reached. D) Lock the adjustment bolt with the nut.
