1. Grease the centering flange with assembly paste to make the process
easier.
2. Screw in two studs into tapped holes on opposite sides of the driven
machine flange. The studs act as positioning aids.
3. Lower the machine slowly toward the driven machine and into the
centering, so that the flanges do not quite touch. Lowering too quickly risks
damaging the centering.
4. If necessary, rotate the machine into the right position so that the clearance
holes in the flange are central to the tapped holes.
5. Lower the machine completely onto the mating flange so that it is fully in
contact; then remove the studs.
6. Fix the machine using the flange fixing bolts.
3.4.3
Removing the rotor shipping brace
If a rotor shipping brace is attached to the machine, remove it at the last
possible moment, for example, when you are ready to push on the output or
drive element.
Store the rotor locking device
Be sure to store the rotor locking device. It must be remounted for possible
disassembly and transport.
Details about the alignment accuracy can be found in the Section "Information
about the machine dimension drawing".
3.4.4
Recommended alignment accuracy
The alignment accuracy required depends essentially on the configuration
of the overall machine train. Observe the required alignment accuracy of the
coupling manufacturer in all cases when aligning the machine.
