Helical Reduction Gearboxes

Helical reduction gearboxes are available in a modular concept, the centre distances, ratios, dimensions corresponding to R10, R20 and R40 series. Highlights include: easy servicing – weight/power optimised due to use of casehardened steels of high strength; bearings designed for life time fitted on integral shaft pinions; hardened and profile ground helical gears running noiseless in vibration free steel fabricated/graded cast iron gearbox duly stress relieved and machined on precision machines; computer aided design based on Buckingham method resulting in compact and robust gearboxes with factor of safety greater than equal to 1.5 both in wear and strength for gears and pinions; integral pinion shafts supported between bearings to make these resist torsional and bending stresses, taking advantage of recent advances in the gear technology; and high efficiencies – 99% for single reduction, 98% for double reduction and 97% for triple reduction and 96% for quadruple reduction helical gearboxes.
