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.
Risk that the function will not be able to be maintained in the case of a fault/fire
Temperature-related fan imbalance and temperature-related changes to mounting
resonance points in the equipment result in vibration levels that automatically increase. This
can result in material damage, injury and death.
Before balancing, anneal the output transmission elements (fans) to relieve any internal
stress. Avoid any mounting resonance points in the equipment close to operating speeds.
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.
