•
Clean all components and shaft ends carefully (see chapter 7.6). The O-rings (component 8) must not get in
touch with solvents and detergents.
•
Lightly grease the O-rings (component 8) and insert in the corresponding keyway of the sleeves (component
2).
•
Lightly grease the sealing surfaces on the face of the sleeves (component 2) and push them over the shaft
ends. Make sure that the O-rings (component 8) are not damaged.
To facilitate the assembly, heat the hubs (component 1) or flange hub (component 12)
evenly by inductive heating (approx. 80 °C), either in the furnace or by means of a burner.
•
Push the hubs (component 1) or flange hub (component 12) onto the shaft of the driving and driven side until
the front faces of the hub are flush with the shaft ends. When the hubs are heated, any contact with the O-
rings (component 8) should be avoided.
Make sure with the assembly that the shaft ends do not protrude over the front face of the
hub.
•
Valid with coupling hubs with feather keyway and setscrew only:
Fill the tapping for axial fastening with sealing compound for 2/3.
•
Secure the hubs (component 1) or flange hub (component 12) axially by tightening the setscrews
DIN EN ISO 4029 by means of a cup point (tightening torque T
A
see table 9), an end plate or by shrinking.
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 1, 5 and 7).
•
Align both shafts and inspect the permissible displacement figures as per chapter 4.6.
•
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 hole of the sleeves (component 2) or flange hub (component 12) flush. Please make sure that
the lubrication holes on both sleeves have an angle of 90° versus each other.
•
Applying for type FH only:
Push the spacer (component 13) between the two sleeves and align the fitting holes flush with the sleeves.
•
Please insert the flat gasket (component 5) and screw together the sleeves or sleeve and flange hub,
respectively, by means of the dowel screws (component 3) and nuts (component 4), observing the tightening
torques specified (see table 9).
•
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).
