5.3.2 Aligning the machine to the driven machine and mounting
5.3.2.1 Horizontal types of construction with mounting feet
1. Refer to any instructions for aligning the driven machine and those of the coupling
manufacturer.
2. Align the machines with coupling output to the driven machine in such a manner that the
center lines of the shafts are parallel with no offset. This ensures that no additional forces
affect their bearings during operation.
3. For the vertical positioning (x→0) place thin shims under the machine feet. The number of
shims should be kept as low as possible, i.e. stack as few as possible. This also prevents
the machine being subjected to any stress/distortion. If available, use the existing tapped
holes for the forcing-off bolts to somewhat raise the machine.
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 fixing 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.
NOTICE
Damage to the bearing
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
Damage to the bearing
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.
5.3.3 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.
