The 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 little maintenance 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.
