Stainless steel bevel gears

DZ TRASMISSIONIDZ Trasmissioni developed a stainless steel series of gears, widely used in food machinery, especially in the wine sector. The construction of the monobloc casing in Aisi 316 L using a modern precision casting system, unlike many other groups obtained with welding systems, prevents oxidation of the welds, where the material structure changes and creates oxidation stains. Next to the stainless steel series, recently the new “Cubitale” series of gearboxes was born, whose name derives from the shape of the gearbox. For the first time aluminium has been used instead of cast-iron for the gear casing, saving up to 50-60% in weight. The advantage is that aluminium can be submitted to treatments that are not possible with cast-iron. Installed on a filling machine, the new “cubital” unit, thanks to the patented GHA (Golden Hard Anodizing) treatment with a thickness of 20 micron on the gearboxes, provides a product life of 10,000 hours in saline mist compared whereas stainless steel casings only have a duration of 6000 hours, and with lower costs. Even shafts and/or sleeves are Aisi 316 L. The seals are in silicon or Viton, and for very critical situations even PTFE.
