●
Avoid exposing them to direct, intense solar radiation, rain, snow, ice, or also dust for
extended periods. Attach a covering structure or an additional cover when using or
storing outdoors.
●
Do not exceed the permissible axial and radial forces.
5.2.4
Balancing
The rotor is dynamically balanced. For shaft extensions with feather keys, the balancing type
is specified using the following coding on the face of the drive end of the shaft:
●
"H" means balancing with a half feather key (standard)
●
"F" means balancing with a whole feather key
●
"N" means balancing without a featherkey.
CAUTION
Risk of injury due to Incorrect installation or removal
If the required touch protection measures for drive output elements are not observed this
can result in physical injury and material damage.
•
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.
The featherkey data on the shaft and transmission element must indicate the correct type of
balancing in each case and must be correctly mounted.
The balancing quality corresponds to vibration severity grade "A" for the complete machine;
vibration severity grade "B" is possible as an option, i.e. in order to ensure the desired
balancing quality, it must be ensured that the featherkey data on the hub and machine shaft
complement each other in the case of a shorter or longer output transmission element.
Align the offset at the coupling between electrical machines and the driven machines so that
the maximum permissible vibration values according to ISO 10816-3 are not exceeded.
