Flange Mounted and Atex
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.
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)
Brevini lanetary gearboxes
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.

"High Power" Series
Brevini High Power gear units for medium and high power industrial applications combine the innovative technology and performance of Brevini’s latest S series range with the high quality and reliability of PIV Drives’ Posired series of right-angle gearboxes.
The result is a new series of right-angle gear units that has all the benefits of versatile output configurations typical of planetary gear units combined with the tested input safety of high quality right-angle gearboxes, a solution that is more efficient, quieter, more compact and offers a better price / performance ratio compared to ordinary gear units.
The application range of these new Brevini Power Transmission gear units includes a variety of ratios – from 1:75 to 1:660 – and a transmission capacity of up to 950 kW of power. These gearboxes are the result of the partnership and the teamwork between Brevini and PIV.
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.
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.
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 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.
Other Planetary Gears
Brevini's range of mixer drives are planetary gear units modified to meet the operating requirements of water conditioners and of mixers in chemical, ceramic and paper producing industries. The mixer drives combine the traditional advantages of Brevini's planetary technology - compactness and high efficiency - with the characteristics of strength and reliability.
The flexibility of the mixer drive design provides users with a number of construction options, including in-line and right-angle configurations, and the facility to directly mount a motor to the gearbox via a flange. Alternatively, a male input shaft configuration may be used with connection effected by a flexible coupling or pulley.
In specific sectors and applications, where it is necessary to provide innovative and versatile solutions to power transmission problems, Brevini's modular planetary gearboxes are the right choice: in mobile machines and industrial equipment as well.
Starting from the Customer's requirements, our gear units can add configurations, motors, brakes and accessories, in order to customize the transmission system to the specific segment of application: cattle feed mixers (see picture on left), concrete mixer, snow cats, power shift and gearboxes for drilling equipment, packages with right-angle gear units or with input worm reduction set.
The Brevini pump drive gear units can drive up to 5 pumps from a single prime mover: diesel engine or electric motor.
