Basically make sure with the assembly that the shaft-hub-connection is sealed such that
grease cannot escape from the coupling.
Before filling with grease coupling hubs with feather keyway and setscrew have to be
cooled down to ambient temperature in order to prevent escaping of lubricant in the area of
the feather key.
•
Shift the power packs in axial direction until the distance dimension E is achieved (see table 3, 5 and 7).
•
Align both shafts and inspect the permissible displacement figures as per chapter 4.6.
•
Put the O-rings (component 11) onto the pilot of the cover (component 9).
•
Afterwards push the sleeves (component 2) onto the hubs (component 1).
•
Screw the cover (component 9) and the sleeves (component 2) with the cap screws (component 10) (for
tightening torque T
A
see table 10).
•
Push the sleeve along with the cover far over the hub and put it onto the shaft ends. Make sure that the O-
rings (component 8) are not damaged.
•
Grease the spline of the hubs (component 1) and sleeves (component 2) (grease capacity see table 12),
afterwards push the sleeves over the spline of the hubs and keep them in place.
•
Align the fitting holes of the sleeves (component 2) flush. Please make sure that the lubrication holes on both
sleeves have an angle of 90° versus each other.
•
Applying for type DH only:
Push the spacer (component 13) between the two sleeves and align the fitting holes to be flush with the
sleeves.
•
Insert the flat gasket (component 5) and screw the sleeves together by means of dowel screws (component 3)
and nuts (component 4), observing the tightening torques specified (see table 10).
•
Please observe the instructions specified in chapter start-up and lubrication (see chapter 5).
With each reassembly of the coupling we recommend to replace the flat gasket (component
5) and the dowel screws (component 3) as well as nuts (component 4).
