Helical Gearboxes

We have h series bevel helical gearboxes and helical gearboxes:
agnee h series helical parallel shaft and bevel helical right angle drive industrial gearboxes have been introduced to meet the requirements of today's demanding applications in the medium and heavy-duty sector of the power transmission market.
the modular design and construction of the series h offers many engineering and performance benefits including a high degree of interchangeability of parts and sub assemblies. This in turn provides considerable economies of production while maintaining the highest standard of component integrity.
apart from standard range, gear boxes are also tailor made to suit individual requirement or as per specifications provided. Please feel free to discuss your requirement and we shall be pleased to make suitable suggestions.
product specification:
gear tooth geometry design combines maximum efficiency with high load carrying capacity and minimal noise generation. Serviceability of the product was key in the design of the series h range allowing easy maintenance for long life and reliability, which are synonymous with our field reputation.

the bevel helical gearbox housing is usually made of close grain cast iron. Sometimes housing is also offered in structural steel when the application demands. They are rugged, corrosion resistant and absorb shock and vibration. The helical pinion is made of en 353 case hardening steel, helical gears are made of sae 8620 case hardening steel. The teeth are generated on gear hobbing machine. They are then case carburized, hardened and tempered. Finally, they are surface ground to close tolerances. The teeth flanks are ground on teeth profile grinder. This leads to very good efficiency and a quiet working condition. The output shafts are from alloy steel forging or bars. Low speed shafts can be solid or hollow type. Bearings are fitted on a accurately bored journal and taper roller bearings are used.
