The gearbox plays a crucial role in the drive system of a Maxcell hammer shredder, produced by Dedini, which boasts an impressive configuration of 176 hammers and the capacity to shred up to 20,000 tons of sugarcane per day. It seamlessly receives motion from a three-phase induction motor, equipped with slip rings, delivering a power rating of 6700 Hp and operating at a synchronous rotation frequency of 900 rpm. The gearbox itself is a parallel reducer featuring a bi-helical gear stage, constructed using cutting-edge technology. It incorporates hardened steel and precision-ground teeth, meticulously manufactured to meet tolerances 3 and 4 in accordance with ISO standards.
The gear synthesis of this gearbox, with carefully selected backlash and module, allows for proper tuning with the driven machine, ensuring optimal operation in the extreme application for which it was designed. Additionally, the gearbox is equipped with a factory-mounted electronic system for measuring the temperature of each bearing, capable of issuing alarm signals and triggering shutdown. The lubrication system includes a flow meter, and the main mechanical pump has an electric backup pump. In addition, there is a signal indicating the cleanliness status of the filters and an internal oil level (added by the customer). This complete system is ready to be connected to the customer’s Automation system through a standard 4-20 mA signal.
