Bonfiglioli Transmission (Australia) was
expected to highlight the torque density of
its Transmital planetary drives. These
multi-stage (up to 6 stages) planetary
drives can handle peak torque outputs of
more than 1,000,000 Nm and continuous
outputs of more than 500,000 Nm. They
are extremely efficient in transmitting
power and very compact. Bonfiglioli has
invested $16 million in design and production
facilities and inventory, and these
gearboxes can be specified and assembled
in Australia. The drives are complemented
by a broad range of drive types, ranging
from small worm drives through to traditional
parallel shaft and bevel helical
gears. The new HDP and HDO bevel helical
units are offered in sizes up to 72,000
Nm. Bonfiglioli has also developed modern
electric drives, including the Variable
Voltage, Variable Frequency (VVVF) and
Field Orientated (Vector) Variable Speed
Drives, which replace older technologies
such as slip ring motors, fluid couplings,
DC motors or eddy current couplings in
variable speed applications.
The Bonfiglioli ACT series has four data
sets (memories) that are independently
adjustable and remotely switchable. This
allows users to have up to four totally different
operating characteristics from a single
drive. When combining the multiple
data set functionality with the features
offered in a single data set (4 logic modules,
2 comparators, 2 timers, multiple
fixed or infinitely variable speed motor
speed, multiple starting and stopping methods,
etc), huge variations in machine control
from a single inverter are achievable.
Power factor correction and improved system
efficiency in these drives reduces the
energy draw and the environmental impact.
