Please ensure sufficient ventilation and follow the detergent manufacturers’ notes regarding
the handling of solvents and detergents.
Avoid any kind of ignition sources.
With assembly/disassembly of the coupling, the coupling components should be subject to careful cleaning.
Specifically the sealing surfaces and the area of the spline should be free from dirt, wear and old grease.
A subsequent correct assembly (chapter 4) and start-up (chapter 5) has to be ensured.
If the maximum standard values of wear as per chapters 7.4 and 7.5 are achieved, the coupling half has to be
replaced completely.
Replacement may only be effected in pairs (hub (component 1) and sleeve (component 2)) for each coupling half!
Disassembly has to be performed as per chapter 7.8.
!
If the advice is disregarded and the limit of wear is exceeded, the coupling may be
damaged.
The failure on the coupling may cause standstill of the drive and the overall machine.
Rotating particles may cause danger to life.
STOP
With disassembly, operation and maintenance of the coupling it has to be made sure that
the entire drive train is secured against accidental switch-on.
!
In case if a dimensional drawing was prepared for the coupling, the dimensions specified
have to be primarily observed.
The operator of the machine should be provided with the dimensional drawing.
It is necessary to disassemble the coupling if coupling components have to be inspected for damages or have to
be replaced. Moreover, disassembly is necessary to replace the sealing elements.
•
Drain the grease as per chapter 7.2.
•
Unscrew the dowel screw connection and push the sleeves (component 2) axially backwards until the spline is
no longer engaged.
•
Mark the spline of the sleeves (component 2) versus the hubs (component 1).
•
Move the power packs apart.
•
Clean the coupling (see chapter 7.6) and inspect the coupling components, sealing surfaces and spline.
•
Replace damaged components.
•
A reassembly has to be performed as per chapters 4 and 5.
!
Components that are damaged or worn off have to be replaced!
