The gearboxes, series RN, RO, RV are manufactured with a common housing that allows the same footprint for the three versions and are designed according to latest ISO engineering specifications with the help of computer aided structural analysis for displacement and stress field.
The monolithic framework does not deflect under the effect of torque and external loads with effective results on sealing surfaces.
The gearboxes of series RN, RO, RV are manufactured of pressure die cast for the first 3 sizes and of cast iron for the others.
The shaft mount version, common to the three types, allows the flange mount B5 conversion by simply fitting one of the many output flanges available. Various dimensions and types of output shafts (hollow with through keyway, hollow with shrink disk and solid with single or double end) are available for the majority of applications.
The series RN, RO, RV are made in 6 sizes for each type of gearboxes, 30 reduction ratios and output torques between 100 and 3400 Nm.
The gearbox series RN-RO-RV is made of a common housing that allows same footprint for the three versions: - RN - parallel shaft gearboxes, hollow output shaft, two- and three-stage execution. - RO - bevel/helical gearboxes, in-line input, hollow output shaft, three-stage execution. - RV - bevel/helical gearboxes, right angle input, hollow output shaft, three-stage execution.
