BONFIGLIOLI has announced a major update and expansion of its range of compact and versatile A series bevel helical gearboxes, noted for their high torque and efficiency.

Three new sizes are being released to complement the existing range, covering areas not previously catered for by the company.
The highly durable Bonfiglioli A series – now available in 12 sizes from 0.9-55kW and 150Nm-14000Nm torque – achieves its versatility by having a ratio range up to 1700:1 in a single gearbox (with four reduction stages in its three larger sizes).
The new A05 bevel helical gearbox will cater for an area of very special interest, covering a range of applications historically dominated by worm gearboxes, says Mr Lewis.
Compared to equivalent worm gearboxes, however, the A05 bevel helical gearbox will offer much higher efficiency, from a minimum of +12% to a maximum of +85% depending on the gear ratio.
The new A05 gearbox will therefore provide a high efficiency alternative for manufacturers eager to achieve energy savings, or simply optimise the performance of their machines.
Compared to conventional worm drives, in some cases the A05 bevel helical gearbox will even permit the use of one size smaller motors, with consequent savings in overall dimensions and costs.
Other key features of the A05 gearbox are an essential design, symmetrical mounting, compact size, extended versatility and universal applicability thanks to its many mounting surfaces.
A35 – The A35 gearbox will complete Bonfiglioli’s offering in the most popular range for industrial gearmotors, with a unit that is top rated within its category.
The A35 will also offer a range of gear ratios spanning up to i=400, in an evenly spaced progression with 12% difference between consecutive ratios. The A35 will be also extremely easy to configure through various motors, two different mounting flanges and five versions for the output shaft.
A55 – The A55 gearbox is of a brand new design, characterised by torque capacity consistently high over a wide range of ratios, spanning from a minimum of i=5 to a maximum of i=800.
Two different casings, one 2-stage and one 3-4 stage, will be used allowing optimisation of costs, performance and dimensions in a manner otherwise not possible.
The A55 will also be extremely versatile thanks to a broad range of standard options that can be selected from the catalogue for configuring the gearmotor according to any application requirement.
Bonfiglioli A series drives features FEA (Finite Element Analysis) procedures in its design and construction.
These allow for lightweight construction whilst maintaining strength and durability from case-hardened nickel chrome steel gears, says Mr Lewis, who added that major features of the A series include high torque, high efficiency and low noise.
Operating efficiencies are enhanced by Bonfiglioli’s high performance patented hypoid bevel gear pair, which gives significant energy savings. Low noise gearing is achieved by locating the bevel gear pair at the output stage of the gearmotor.
This allows noise reductions significantly below similarly sized traditional bevel helical gearmotors. It allows the A series to conform to the most arduous of mechanical specifications.
The A series wide ratio range (with up to four reduction stages in the larger units) permit one A series to be used where previously two gear units increased dimensions and cost.
The A series is also available with compact motors, to further reduce overall dimensions and increase cost-effectiveness.
