Galbiati Group recently implemented a main gear drive for mills and kilns addressed to the cement industry with a rigid electrowelded housing welded and machined on CNC machine tools of modern design.
The main drive is driven by an electric motor 1200 HP with a total weight of 34.000 Kg.
Gears are made from high-quality forgings in electrowelded and carburized steel structure using a special process and ISO-DIN 6 quality ground finished.
Welds are performed by a complete preheating and cooling process due to the different carbon contents and different thermal expansion system of each bearing. (PT 100). Two input shafts, high quality roller type bearings sized for at least 100.000 hours full-load service.
Full speed – reduced load test checks the temperature, vibrations, noise level, pressure and oil flow rates meet the design values, was successfully tested at Galbiati Group workshop in the presence of the customer and the end-user.
