5.2.3 Balancing
The rotor is dynamically balanced. The balancing quality corresponds to vibration
severity grade "A" for the complete machine as standard. The optional vibration
severity grade "B" is indicated on the rating plate.
The declaration regarding the type of featherkey for balancing is generally marked on
the rating plate and optionally on the face of the shaft end.
Designation:
● As a standard measure, balancing is carried out dynamically with a half
featherkey (code "H") in accordance with ISO 8821.
● "F" means balancing with a whole featherkey (optional version).
● "N" means balancing without a featherkey (optional version).
CAUTION
Incorrect installation or removal
To avoid injury and material damage, carefully observe general touch protection
measures for output transmission elements:
The general touch protection measures for drive output elements must be
•
observed.
Drive output elements may only be pushed on or pulled off with the correct
•
equipment.
The feather keys are only locked against falling out during shipping. If you
•
commission a machine without a drive output element, the feather keys must be
secured to prevent them from being thrown out.
Align the offset at the coupling between electrical machines and the driven machines
so that the maximum permissible vibration values according to ISO 10816 are not
exceeded.
