For accurate adjustment, some versions have eccentric mounting between the pinion axis and the casing axis. Their wide range of ratios enables the selection of motor size and type which best suits the customer’s requirements and application. Brevini is proud of its quality assurance policy, including the Type Approval Certificate from DNV.
Brevini Power Transmission planetary gearboxes are used on different part of wind energy plant: the rotor and the nacelle. Our slewing planetary gear units from the yaw and pitch range are normally used to control blade pitch. The nacelle at the top of the tower is connected to the rotor and houses the gearbox, the electrical generator, the yaw system, and the control system. To make sure that the rotor axis is constantly aligned with the wind direction for maximum energy output, large wind turbines are equipped with a yaw system that allows the nacelle to adjust its position according to the direction and force of the wind.
Nacelle rotation is controlled by a yaw system, planetary gear unit with electric brake motor, which is one of Brevini?s most popular products. Each wind turbine must have between two and six gear units, depending on the size, and the motor can be electric or hydraulic.
Two or three-stage gear units, combined with a worm gearbox on the input side, or four or five-stage gear units from the yaw and pitch drive series are normally used. Output pinions can be integrated or inserted. Brevini is proud of its quality assurance policy, including the Type Approval Certificate from DNV.

Brevini winch drives are the ideal solution for all lifting applications: our planetary gear are especially designed for use as winch drives inside cable drums, available with hydraulic and electric motor adaptor. The SMW Series have a planetary pre-stage reduction gear on the input side.
They feature two close-mounted flanges, one of which is attached to the winch frame and the other of which is fixed to the cable drum, the drive housing therefore acts as the main drum mounting.
The special feature of those Brevini gearmotors is the parallel shaft, which provides mounting support and makes it easier to use. These types are manufactured as flange mounted, foot mounted, parallel shaft mounted or combination of these mounting possibilities.
The Brevini parallel shaft helical gearmotors are manufactured in a modular system. The output shaft and flange can be added to the standard parallel shaft gearbox without any change on the gearbox. The housing has mounting points on both sides, which allows mounting from both sides. The input side of parallel shaft gearboxes is flexible.
IEC B5 or B14, standard coupled or with solid input shaft gearboxes are available. The combination with other types of gearboxes can be made with a minimum change. In applications where efficiency and strength is very important, parallel shaft gearboxes are preferred to worm gearboxes. Parallel shaft gearboxes have also advantages in radial loads.
K Series gearboxes are helical-bevel geared monoblock housing gearboxes. Brevini bevel helical gearmotors of the K Series are designed for higher efficiency and higher strength required operations. Input and output shafts are perpendicular to each other.
K Series Brevini gearmotors have flexible connection possibilities which consists of IEC B5 or B14 connection, directly mounted or solid with the input shaft options . Small sizes of K series gearboxes can be 2 and 3 stages.
For bigger sizes only 3-stage types in monoblock housing.are manufactured. K series supplied for high reduction operations up to 6 stages by using double housings.
Brevini Helical in-line gearmotors have been developed according to the single piece housing principle (monoblock) which has advantages in rigidity, oil leakage, noise level and gear strength. All bearings are supported by the single piece housing itself and not by cover plates or other components which connect other parts.
Machining axes with single operation cycle provide high precision and very tight axis tolerance. The housing made of GG20-22 material provides high gear quality together with the high manufacturing technologies achieved. This design ensures both high bearing and gear lifetime; high radial loads are supported.
The bearings, gears and shafts used in the gearbox have been calculated using professional software, and they are implemented according to up-to-date standards. The middle bearing support plate is the best support for bearings used in three stage gearboxes. So wear and deformation caused by working with load are minimized achieving low noise gearbox operation. M series Brevini gearboxes are featured by easy installation and flexible use.
Brevini Parallel Shaft Helical Gearmotors for Hoisting are three stage, helical geared hoist drum drive units produced according to the monoblock principle. With the support of monoblock housings all axes work with single operation to achieve high production precision. V series bolt connections are made directly on the housing with easy connection holes which do not require long bolts. This ensures rigid mounting.
Input and output center distance is extended as much as possible for using larger drums to achieve longer rope service life. The V series gear unit output shaft bearing distance is long and the housing width is extended. Longer bearing distance and taper rolling bearings make them capable of withstanding high radial loads. V series are designed for higher ISO / FEM classes with greater gear face widths compared to products of similar size.
The housing material is GG20 – GG22 cast iron and the gears are made of high quality case carburized steel. The material properties as well as the manufacturing processes are constantly checked. The output shafts are solid output shafts with spline according to DIN5480 and are produced with different dimensions.
These quality Brevini slewing rings are available in numerous versions and dimensions.: from an external diameter of 300 mm up to 4000 mm, with external or internal gears or with no gears.
