NORDBLOC Industrial Gear Unit range provides integrated motor swing base sub-assembly for 60 to 200 kNm torque output

These ready to install modular gear unit systems are completely scalable and custom built to suit specific load, mechanical interfacing and environmental specifications for heavy-duty conveying and lifting applications throughout industry. By specifying a complete sub-assembly, customers are able to reduce their project management burden, timescales and costs using the NORD design service to manage all aspects of the application – as well as making system commissioning more straightforward and simplifying purchasing.

Each modular system comprises gearbox, motor and base frame with options of elastic or fluid coupling, drum or disc brake, radial or axial fan, auxiliary drive, torque support with attachment plate and protective covers as well as sealing system options. Furthermore, a broad choice of temperature management options include fans, external oil/air or oil/water cooling, and several measuring devices and sensor options are available for oil inspection, temperature and bearing condition monitoring.

The modular system design, covering 6 basic installation configurations with identical installation dimensions for all 2 and 3-stage gear ratios, allows an almost endless combination of power transmission sub-assembly options with fast delivery assured from standard off the shelf components. The symmetrical UNICASE gearbox design permits mirror image installation for dual drive applications. NORD’s own wide range of IEC frame energy saving three-phase motors are used throughout, and NORD SK 700E frequency inverters are available to offer complete gear unit and drive solutions with high performance motor control, and connection to all current factory networking communications systems.

NORDBLOC industrial gear units draw on the well proven benefits of the UNICASE housing system – a one piece design produced on specialised CNC machines which offers the highest levels of precision, rigidity and strength. With all bearings mounted directly into the cast iron UNICASE housing, and with no dividing seams between the drive and gear unit, the design allows shaft axes to be staggered in a more compact space-saving arrangement; also allowing the use of larger roller bearings to ensure a longer operational life with quieter running and reduced maintenance burden. Available in four frame sizes form 60,000 Nm to 200,000 Nm, with helical and bevel-helical gear stage designs, the range includes a wealth of options for mechanical interfacing, performance, safety and environmental conditions.
