5.5.2.3 Vertical types of construction with flange
The standard
flange is provided with a centering. The choice of fit for the mating flange on the
driven machine is the system manufacturer's or the plant operator's responsibility.
Note
If the
machine is not fitted with a standard flange, align the machine to suit the driven machine.
Procedure
The machine
axis must be vertical when it is lifted and the flange must be parallel to the mating
flange, so as to avoid seizing and stressing. Otherwise damage to the centering will result.
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.
NOTICE
Removing the rotor shipping brace in the horizontal position.
Dismantling the rotor shipping brace when the machine is in a horizontal position could
damage the bearings.
● Only remove the rotor shipping brace when the machine is in a vertical position.
NOTICE
Turning the motor over without rotor shipping brace
Failure
to
fit the rotor shipping brace can result in damage to the bearings while the machine
is being turned onto its side.
● Fix the rotor in place before you turn the machine into a horizontal position.
5.5.3 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.
