Installation of generator
Installation of generators of model 160
Important
►
The drive belt must not sag
loosely.
When using narrow belt pulleys of type SPA, the clearance between the axes
must not exceed 800 mm. For permissible axis clearances for other belts, ask
the manufacturer.
Maximum tension force (tension) of the drive belt on the shaft
F
max
= 5,000 N at a max. 60 mm axial clearance
from the point where the shaft exits the bearing
plate. The belt tension must not exceed a radial
force of 2,000 N at a max. axial clearance of
60 mm from the point where the shaft exits the
bearing plate. If the belt pulley attachment to the
shaft is placed further out, reduce the tension of
the belt accordingly in order to balance out the
increased leverage effect on the shaft.
Quantity and type of the belts used
y
Adapt the quantity and type of the belts used
to the output of the generator.
y
Observe the maximum belt tensioning force.
