All the gearings - with external toothing, cylindrical, helical and spiral cone ones - manufactured by Rossi Group feature ground surfaces with strict tolerance class (DIN 6) and special surface finishing with profile and helix angle corrections optimized to counterbalance elastic deformation under load. Casings are designed based on specific criteria aimed at maximizing rigidity and containing weight. Casings, there including very large ones, are processed with state-of-the-art machine tools so as to meet the strictest precision requirements. This is why our gear reducers can boost top performance and overall rigidity without compromising compact dimensions, reduced noise emission and low energy consumptionower P1 0, 09 ... 75 kW Nominal torque MN2 d 1 000 daN m Transmission ratio iN 4 ... 6 300 Universal mounting design Strong patented casing Wide size range Rigid and precise cast iron monolithic casing IEC standard motor Pinion of final stage with three bearings Compliance with ATEX 94/ 9/ EC directive ( UT.D 123)
