Preconditions for smooth, vibration-free operation

Preconditions for smooth, vibration-free operation:
● Stable foundation design
● Precise alignment of the machine
● Correct balancing of parts to be fitted to the shaft end.
● Maintaining the vibration velocity according to ISO 10816‑3

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

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.
