•
Clean all components and shaft ends carefully (see chapter
7.6). The O-rings (component 8 and 11) must not get in touch
with solvents and detergents.
•
Valid with split cover only:
o
Apply a sealing agent onto the contact surfaces of the split
cover.
o
Push the split cover together.
o
Screw the split cover together with the cap screws. Extract
the tightening torque from the dimensional drawing
attached.
•
Lightly grease the O-rings (component 8) and insert in the
corresponding keyway of the cover (component 9).
•
Lightly grease the sealing surfaces on the face of the sleeves
(component 2).
Illustration 26: Assembly of the split cover
To facilitate the assembly, heat the hubs (component 1) evenly by inductive heating (approx.
80 °C), either in the furnace or by means of a burner.
•
Push the hubs (component 1) onto the shaft of the driving and driven side until the front surfaces of the hub
are flush with the shaft ends. When the hubs are heated, any contact with the O-rings (component 8 and 11)
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) axially by tightening the setscrews DIN EN ISO 4029 by means of a cup point
(tightening torque T
A
see table 10), an end plate or by shrinking.
