4.3 Assembly of the Hub
Continuation:
!
C A U T I O N !
During the assembly please make sure that the E
DK
or s dimension (see table 3) is
observed, so that the coupling will be assembled free from distorsion in axial direction. In
case of non-observance, the coupling may be damaged.
•
Tighten the clamping screws of the hub with the tightening torque T
A
indicated in table 1.
!
C A U T I O N !
The frictionally engaged and transmittable torques of the clamping hubs are dependent on
the bore diameter (see table 3).
P R E C A U T I O N !
Clamping hubs without feather key may be used in category 3 only.
A T T E N T I O N !
Selection of clamping hubs
With the use in explosion-proof areas the clamping hubs have to be selected in a way that
the difference between the peak torque of the machine including all operation parameters
and the frictionally engaged torque of the clamping ring hub is at least a service factor of
s = 2.
4.5 Displacements - Alignment of the Couplings
The values of displacement indicated in table 6 offer safety in order to compensate for external influences like
e. g. heat expansions, inaccuracies in manufacture etc.
!
C A U T I O N !
In order to ensure a long lifetime of the coupling and to avoid dangers regarding the use in
hazardous areas, the shaft ends must be accurately aligned.
Please absolutely observe the displacement figures indicated (see table 6). If the figures are
exceeded, the coupling is damaged.
The exacter the alignment of the coupling, the higher is its lifetime.
In case of a use in hazardous areas for the explosion group IIC (marking II 2GD c IIC T X),
only the half displacement figures (see table 6) are permissible.
Please note:
•
The displacement values shown in table 6 are maximum figures which must not appear at the same time.
With radial, axial and angular displacement arising at the same time these values have to be reduced (see
illustration 9).
•
Please control with a dial gauge, ruler or feeler whether the permissible displacement values of table 6 are
adhered to.
