January 24, 2017 - NORD DRIVESYSTEMS has engineered an industrial gear unit with 240,000 Nm rated torque load and various application-specific features for a phosphate mine in Morocco. It is to date the largest system with a one-piece gear case.
The drive unit comprises an SK 15407 industrial bevel gear unit, a medium-voltage electric motor with a 450 kW performance rating, a swing base, a hydraulic coupling, and an electro-hydraulic brake. It is one of 26 systems NORD designed according to a stringent set of specifications and taking into account the harsh environmental and operating conditions. These units drive a conveyor that is over two kilometers long and carries phosphate ore with loads exceeding several hundred tons. The gear unit meets the client’s demanding requirements, in particular maximum uptime and = tolerance to peak loads and impacts. The UNICASE gear design prevents leaks and delivers radial and axial load capacities.
The industrial gear design unit allows for mounting on all six sides as well as by means of a flange. NORD’s Casablanca office engineered the drive with the assistance of NORD engineers in France and Germany. The components at the inlet of the gear unit are covered by safety guards to protect operators from the rotating parts. The application side, which includes the gear unit, can be fully disconnected from the motor side via the hydraulic coupling.
