ST16050413 Zambello BC180-XPS-P twin extruder gearbox Bearing

ZT RANGE – With a transmissible torque density up to 14 Nm/cm3 per shaft
The gearboxes of the ZT RANGE are designed for a wide range of applications and requirements,
starting from the typical applications for revolutions of 300 to max. 900 rpm. to where
lower revolution rates from 25 to max. 200 rpm. (ZT2, ZT3 series) are required.
The range is available for centre distances from 24 mm to 200 mm.
On request, also bigger versions can be built.
TST RANGE - Due to those manufacturers who need to increase the power rates
of co-rotating twin-screw extruders, the TST (Twin Super Torque) series is provided with a torque distribution system,
which is able to ensure a considerable increase of the output revs. (up to 1800 rpm.)
and of transmissible torque density (up to 16 Nm/cm3 per shaft).
The dimensions of the gearboxes of the TST range available at present go from centre distances
of 20 mm to 120 mm. However, at the moment bigger sizes are planned.

TST- HD SERIES (High Density) – This new series at the top level worldwide,
which is able to support torque densities of more than 18 Nm/cm3 per shaft,
at present is under development. For any sizes already available please consult Zambello.

Although the range of gearboxes for counter-rotating twin-screw extruders used for medium,
high and very high torques is already very wide, Zambello updates it constantly both with new sizes of
standard products and tailored gearboxes for the exacting needs of customers.
NRB series – With a transmissible torque density up to 17 Nm/cm3 per shaft
The gearboxes of the NRB range have a horizontal shape (mounting position B3), which requires a
connection to the electric motor by belts and pulleys. As a matter of fact, the reduction
ratios available cover a ratio up to a maximum of i=25.

ZT3 series – With a transmissible torque density up to 17 Nm/cm3 per shaft
The gearboxes of the ZT3 series have approximately the same features as the NRB series,
but have a vertical shape (mounting position B7). In this case the connection between gearbox and
electric motor is carried out by an elastic coupling. Due to the possibility to mount the electric motor
in the U arrangement, the final result is a very compact extruder. Reduction ratios available go from i=14 to max. i=80.

TST range – The TST range (Twin Super Torque) is available in two versions: TST-H
and TST- 2H. Both series offer very high performance rates.

TST- H series – With a transmissible torque density up to 20 Nm/cm3 per shaft
The gearboxes of this series are designed for exacting applications, where a high torque is required, which is transmitted
by means of a single reversing unit. The connection to the electric motor is obtained by means of an elastic joint.
The reduction ratios available go from i=14 to max. i=80.

TST- 2H series - With a transmissible torque density up to 22.5 Nm/cm3 per shaft
The gearboxes of the TST-2H series present the highest technical level for which these
are the best worldwide for heavy-duty jobs.
The transmission of the torque is obtained by means of a double reversing unit.
The reduction ratios available go from i=14 to max. i=80.
