Aligning the machine to the driven machine and mounting (IM B3 / IM B35)

1. Refer to any instructions for aligning the driven machine and those of the coupling
2. Align the machines with coupling output to the driven machine in such a manner that the
3. For the vertical positioning (x→0), place thin shims over a large surface area under the
4. When positioning the machine, ensure that a uniform axial gap (y→0) is maintained around
5. Fix the machine to the foundation. The choice of fixing elements depends on the foundation

center lines of the shafts at the operating temperature do not have any parallel or angular
offset. This ensures that no additional forces affect their bearings during operation.
If the thermal change of the motor and the driven machine is different, couple in the cold
state with an appropriate alignment offset. The alignment offset to be set in the cold state
must be determined and specified by the system specialist.
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. Use the
existing tapped holes for the forcing-off bolts to raise the machine.
The balance state of the shaft (full-key or half-key balancing) and alignment errors primarily
influence the service life of the bearing, especially for high motor speeds or when using
rigid couplings.
