Product Details Supplier Info More products

As part of its range of Nordbloc industrial gear units for torque output from 60,000 to 200,000Nm, Nord supplies modular subassemblies.

These comprise Unicase gearbox, motor and coupling with a range of options and accessories.

Fully pre-assembled on torsionally rigid motor swing-base or base-frame mountings, the combined units require no complex alignment and are supplied fully tested.

The ready-to-install modular gear unit systems are scalable and custom built to suit specific load, mechanical interfacing and environmental specifications for heavy-duty conveying and lifting applications.

By specifying a complete subassembly, customers can use 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.

A choice of temperature-management options includes 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 six basic installation configurations with identical installation dimensions for all two and three-stage gear ratios, allows a range of power-transmission subassembly options.

The symmetrical Unicase gearbox design permits mirror-image installation for dual-drive applications.

Nord’s 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 Unicase housing system, a one-piece design produced on specialised CNC machines, which offers high 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, 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 to 200,000Nm, with helical and bevel-helical gear stage designs, the range includes options for mechanical interfacing, performance, safety and environmental conditions.
