he well-known MAXXDRIVE industrial
gear units from NORD provide high
output torques from 15 to 240 kNm
and are ideal for use in heavy duty applications
such as agitators, belt drives, mixers, mills, drums
or crushers. NORD DRIVESYSTEMS now presents
a new industrial gear unit series (MAXXDRIVE
XT), which optimises the proven modular system
for applications with high thermal limit powers.The NORD range has included MAXXDRIVE
industrial gear units for ten years and in this
time, they have been developed further. The
latest generation supplements the long-standing
series with an application-optimised two-stage
angled gear unit, which is especially suitable for
conveyor belt systems and can be individually
tailored to the particular application. The power
and speed range was specially designed for the
industry, in which low speed ranges are required
in combination with high powers. This is the case
for example in the bulk material and minerals
industry. There, especially robust solutions are
required which are resistant to dirt and are
reliable in rough operating conditions. For this,
special sealing concepts which require as littlemaintenance as possible are necessary. Because
of this, the drive systems must also not require
external cooling.Cooling concept for high power limits
Output torques of the MAXXDRIVE XT series range
between 15 and 75 kNm with speed ratios of 6.3
to 22.4. MAXXDRIVE XT industrial gear units are
available in seven sizes for powers from 50 to
1,500 kW. In contrast to the previous designs,
as standard the series is equipped with a heavily
ripped UNICASE housing with an integrated axial
fan. Due to the increased surface and the air
guide covers, the cooling air flow is optimised
and a very high thermal limiting power is
achieved. In many cases, addition cooling is
not required. Large roller bearings and centre
distances increase the load capacity and service
life of the components.Economical modular system
All NORD drive solutions are planned for
individual customers according to the modular
principle. With the matched modular system
attractive solutions can also be provided for
price-sensitive industries. This is based on a
comprehensive range of frequency inverters,
motors and gear units, as well as coupling and
brake systems, each with a wide variety of
options. Features such as hydraulic couplings
tailored to the particular process or Taconite
seals, which effectively protect shaft sealing
rings against abrasive dust and corrosion, ensure
smooth operation.Networked maintenance concepts
NORD also offers innovative predictive
maintenance concepts especially for heavy
industrial gear units. Via the frequency inverter,
networked NORD drive units communicate
their status data via the control system or
communicate directly into a secure Cloud.
With optional vibration monitoring, condition
changes can be detected at an early stage and
predictive maintenance can be scheduled in
good time. Recording of the performance data
also ensures optimal dimensioning of the system
as well as continuous condition monitoring of
the drives. nNew MAXXDRIVE XT Industrial gear unit from
