Helical–Worm Combination Gearboxes (RVF-Helical Worm)

RVF series gearboxes are a variant of the VF series and feature an initial speed reduction gearbox containing a pair of helical gears mounted on the input shaft of the worm gearbox, enabling reduction ratios of up to 1:300. These two helical gears are housed in a separate casing that is lubricated independently from the worm gearbox. The motor is connected to the pinion via a flange, forming an integrated and robust assembly.
