4. When positioning the machine, ensure that a uniform axial gap (y→0) is maintained around
the coupling.
5. Fix the machine to the foundation. The choice of xing elements depends on the foundation
and is the plant operator's responsibility.
Note
Machine expansion
When aligning, make allowance for the thermal expansion of the machine when the
temperature increases.
5.5.2.3 Horizontal types of construction with ange
The standard ange is provided with a centering. The choice of t for the mating ange on the
driven machine is the system manufacturer's or the plant operator's responsibility.
If the machine is not tted with a standard ange, align the machine to suit the driven
machine.
Procedure
The machine axis must be horizontal when it is lifted and the ange must be parallel to the
mating ange, so as to avoid seizing and stressing. Otherwise damage to the centering will
result.
1. Grease the centering ange with assembly paste to make the process easier.
2. Screw three studs into tapped holes spaced about 120° apart around the driven machine
ange. The studs act as positioning aids.
3. Position the machine so that its axis is aligned with that of the driven machine, but not yet
quite touching. Advance the machine slowly towards the driven machine; advancing too
quickly risks damaging the centering.
4. If necessary, rotate the machine into the right position so that the clearance holes in the
ange are central to the tapped holes.
5. Move the machine fully up against the mating ange so that it is fully in contact.
6. Fix the machine using the ange xing bolts, nishing by replacing the studs.
5.5.2.4 Vertical types of construction with ange
The standard ange is provided with a centering. The choice of t for the mating ange on the
driven machine is the system manufacturer's or the plant operator's responsibility.
If the machine is not tted with a standard ange, align the machine to suit the driven
machine.
