Established manufacturer of angular gears, DZ Trasmissioni offers the “Cubital” series of gears, which is lighter, sturdier, more accurate and convenient. Lightness is guaranteed by the housing made of aluminium rather than cast iron. Accuracy (with extremely small angular backlash as guaranteed) is provided by the housing structure consisting of two parts only (monobloc for the smaller size) instead of four or more parts (not for the larger size). Reduced centering on bearings, flanges and relevant threads guarantees higher accuracy while reducing costs. As for the sturdiness, the design with seeger rather than flanges and threads allowed wider bores, thus favouring the assembly of larger gears but having equal external dimensions. Wider bores involve also larger bearings, and with equal external dimensions, this means higher actual performances. These assemblies, notably thanks to the aluminium structure providing for lightness and higher resistance to oxidation, are widely used in the bottling sector.
