Advanced technology heavy drives are being custom-engineered by Bonfiglioli in Australasia to achieve optimum cost-efficiency and reliability with clean and robust service to aerate or mix liquids. Bonfiglioli’s HDP parallel shaft helical gear drives are an outstanding new generation of large industrial gearbox assembled in Australasia to produce exceptional reliability and torque densities to record values, says the managing director, Bonfiglioli Transmission (Australia) Pty Ltd, Malcolm Lewis. The drives feature excellent torque distribution across their entire ratio range, with gear ratios laid out in close progression and the drives 42 July 2016 E N V I R O N M E N T EN075 marketplace, with output torque ranging from 4720Nm to 215480Nm. Bonfiglioli’s HDP range features a housing made from spheroidal cast iron; monobloc from HDP60 to HDP120 and horizontally split HDP130 to HDP160. Bonfiglioli’s Drives Service Centre (DSC) enables Bonfiglioli to respond rapidly to local industry’s needs for drives required for prompt delivery to avoid costly delay or downtime. Reliability in service is enhanced by the HDP drives’ finite element analysis and multi body simulations conducted extensively to identify the stress pattern on each of the main components and to optimize the design for: • System structural stiffness • Gear geometry • Shaft deflection • Extended gear and bearing lifetime MIXING IT Cleanly cost-efficient HDP drives custom-engineered by Bonfiglioli for aerator and liquid mixer applications An Australasian example of the drives locally engineered for a waste water application cost-effectively integrated 55kW six-pole motors with HDP helical parallel series drive featuring output shaft dry well and a mechanically driven OP2 lubrication pump. The drives – specified for 55kW power and 10 kNm output torque – incorporated an integral mechanically driven OP2 lubrication pump to ensure optimum bearing performance in vertical motor mounting arrangements. They were also epoxy coated for optimum corrosion protection, cleanliness and durability. The drives incorporated an output shaft dry well feature to safeguard against oil leaks into process liquids as seals age and wear. “While these particular drives were for aerators at a wastewater BONFIG STYLE having a rugged capacity to cope with the shock and impact of intermittent loads. The full range of Bonfiglioli large parallel shaft gearboxes has been extended for the Australian KNOBS & HANDLES Extensive range in stock, fast delivery • Knobs & handles • Handwheels • Levers • Adjustable feet H_2370 Available from Hi-Q Electronics Limited engineering@hiq.co.nz 0800 766 709 www.hiqknobs.co.nz
