Installation of generator
Installation of dual-bearing generators (BG 160)
Important
y Loose belts can spring off and
do not reliably transmit the drive
power.
►
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. 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.
