Brevini Riduttori
The company was founded in 1960 by three brothers, Renato, Luciano and Corrado Brevini, in the town of Reggio Emilia (Italy). Since then, the name of Brevini has become synonymous with planetary gear units.
For more than 40 years now we have been developing and refining a technology of which the prominent attributes are a competitive price/performance ratio, compactness, modular design and reliability, all achieved even in extreme situations.
From the very start we have had the world as our market, and today Brevini maintains a presence around the globe, with 24 subsidiaries and an extensive distribution network.
The latest 10 years saw a significant increase in sales, from 86 to 284 million euros, also in jobs, from 470 to 1.000, and in output, which rose from 67.000 to 172.000 gearboxes per annum.
Encouraged by this positive response from the market, we now aim to expand further worldwide and widen our range of offerings through acquisitions and agreements on the key power transmission markets.
A further step has already been taken in this direction with the acquisition of PIV Drives GmbH, a German company with a long and historic tradition (founded 1928) in the field of mechanical power transmission.
Foot Mounted
Torque (T2max) Nm: up to 18.000
Transmission Ratio: up to 3.150 iN
Power Rating kW: up to 180
A design which integrates mounting feet into the gearbox housing means that Brevini's range of in-line and right angle gearboxes offer advantages in terms of high levels of operating stiffness and rigidity.
The use of tapered roller bearings in the construction of these compact high efficiency gearbox units adds to their robust performances, by allowing axial and side loads to be tolerated on their keyed cylindrical output shafts. The provision for foot mounting means that this range is particularly suitable for industrial applications. This suitability is enhanced by a wide range of accessories, including adaptors for electric and hydraulic motors.
Shaft Mounted
Torque (T2max) Nm: up to 900.000
Transmission Ratio: up to 3.150 iN
Power Rating kW: up to 720
In applications where it is necessary to ensure proper alignment between a gearbox and a driven shaft, Brevini's in-line and right angle shaft mounted planetary gearboxes provide the ideal solution.
The ability of the compact and efficient shaft mounted gearboxes, not only to provide alignment between shafts, but also their flexibility of use and the fact that no machining is required to mount them to frames, are all major factors in their widespread use across all industry sectors. Complementing these user benefits is the flexibility offered by two different types of shaft configurations: hollow shaft for shrink disc connection or keyed cylindrical female shaft (FP type).
Flange Mounted and Atex
Torque (T2max) Nm: up to 900.000
Transmission Ratio: up to 3.150 iN
Power Rating kW: up to 720
Brevini's in-line or right angle planetary gearboxes can be used in a wide range of industrial equipment and mobile applications. They are based upon a flexible modular system and are available with either male or female output shaft configurations.
The male configuration (cylindrical or splined) is used where side or axial loads are acting upon the output shaft. The female configuration is used to transmit purely torque and is employed where space is limited. The flange mounted gearboxes are supported by a wide range of accessories. These include: adaptors for electric and hydraulic motors, multidisc failsafe brakes and male input shaft configurations.
High Torque "S Series"
Nominal Torque: up to 370,000 Nm
Transmission Ratio: up to 670 iN
Power Rating: up to 950 kW
The "S Series" is the optimum proposal for all applications requiring high torque with minimum dimensions, on fixed industrial equipment and also self-propelled machines. This epicyclic solution is preferable to solutions with traditional gear units as it offers an improvement of 40-60% in terms of space and weight.
With its many output versions, numerous input possibilities and all the accessories supplied, the "S Series" extends the application possibilities of Brevini epicyclic gear units to all industrial sectors: mixers for any type of material, extruders, all types of conveyors belts, industrial and port lifting equipment, grinders and mills, machines for working sheet and rod, large iron-making plants, sugar and food oil production plants, plants for quarries and mines, purification plants.
Wheel Drives
Torque (T2max) Nm: up to 40.000
Transmission Ratio: up to 52 iN
Compact planetary wheel drives, designed for a wide range of self propelled vehicles with hydraulic transmission and individually motorised wheel drives.
They allow design engineers to simplify the project of mobile equipment, improving the price / performance ratio.The wide range of ratios available makes it possible to adapt the reduction unit to the most suitable hydraulic transmission. A manual release is provided, to disconnect the reduction unit from the motor for emergency towing. The versatility of this range of Brevini products is assured by a wide choice of braking systems (drum brakes, negative acting multiple disc, failsafe parking brake).
Important applications: agricultural machines, access platforms, fork lift trucks, sweepers, low speed wheeled vehicles.
Track Drives
Torque (T2max) Nm: up to 100.000
Transmission Ratio: up to 190 iN
Compact planetary track drive units, specifically designed for use on tracked vehicles: excavators and earthmoving machines.
This range of gearboxes has high strength structure, short overall length, very high radial and axial load capability. All the gearboxes are provided with integral multidisc failsafe brake and allow the direct mounting of hydraulic motors at the gearbox input.Due to the high torque rating and the quality of the materials, these units are the best solution in heavy duty applications.
Brevini produces the track drives also in gearmotor version, with integrated hydraulic motors, specifically designed for the tracked mini-excavators.
Slewing Drives
Torque (T2max) Nm: up to 96.000 Nm
Transmission Ratio: up to 355 iN
Brevini’s slewing drives are an essential component in keeping weight and size to a minimum on equipment such as tower cranes, wind turbines, aerial platforms, discharge booms and excavation and construction equipment.
Their planetary structure means that they can withstand very high torque values while maintaining reduced dimensions, reduced weight and high efficiency. The wide range of ratios available enables the selection of a motor size and type which best suits users requirements: hydraulic, electric, pneumatic. Simple mounting, operating reliability and versatility make these units suitable for the most severe duties and environments.
Brevini produces the slewing drives also in gearmotor version, with integrated hydraulic motor and brake, specifically designed for mini-excavators and light duty machines.
Winch Drives
Torque (T2max) Nm: up to 60.000
Transmission Ratio: up to 180 iN
Brevini planetary gear units, with rotating outer casing, are designed to be fitted into the winch drum: the PWD series for drive applications from 3 to 12 tons and the SLW-SCW series for applications exceeding 12 tons.
These winch drives have two flanges close together: one is bolted to the fixed winch frame and the other is bolted to the drum, thereby serving as its first support.
The drum and winch frame come in any shape and size: the only engineering restriction is the spigot on the flange coupling when fitted. The winch drives are attached to the drum with bolts inserted from the motor side to permit easy, immediate access to filling, level and drain plugs. Thanks to the caterpillar seals, all units are protected against adverse environments and can be treated against sea corrosion with an epoxy paint coating.
Through this solution, Brevini Riduttori provides manufacturers with a standard product that can be adapted to suit specific sizes, which means lighter, more compact winches can be made.
PWD and SLW-SCW series performance has been rated in conformity with FEM M5 standards, with an output speed of 15 rpm, which are the most widely accepted standards on the market for self-propelled and onboard cranes.
