10.9 Vibration measurements
DANGER
Danger to life from rotating and/or moving parts
Risk of being gripped or drawn in by rotating and/or moving parts.
If a mobile vibration measurement is taken on a gear unit while it is in operation, it is imperative to ensure
that the measurement is not taken directly near rotating parts in order to avoid accidental contact with
the rotating parts.

The measuring points shown in Figure 11 are the standard measuring points in a mobile measurement.
All gear units of this type in the field can be measured on these measuring points. This enables direct
comparison with other gear units of the same type and same size. A detailed illustration of the gear unit is
contained the drawings in the gear unit documentation.
Vibration measurements and their evaluation should be conducted by Siemens personnel and/or in close
collaboration with Siemens personnel. This way, experience gained from measurements conducted on
comparable bevel-gear planetary gear units can be incorporated into the measurement and the evaluation
of its results.
