DANA Slewing Drives
Feature | DANA Slewing Drives
This wide range of Brevini planetary gear units is specifically designed for pinion and slewing ring drives. Successfully employed on tower cranes, shipboard and harbor cranes, wind generators and as steering drive on ship propulsion systems, they can be used in all applications where accurate positioning is called for. These Brevini slewing drives are suitable for the most severe duties in every environment. The design of the planetary units optimizes torque performance and radial load capacity, in order to give perfect meshing between pinion and ring gear. 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.
Feature | DANA Yaw and Pitch Drives
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.
Feature | DANA Mobile Slewing Drives
Brevini’s slewing drives are an essential component in keeping weight and size to a minimum on equipment such as tower cranes, aerial platforms, discharge booms, excavation and construction equipment. Their planetary structure allows to withstand very high torque values while maintaining reduced dimensions, reduced weight and high efficiency. These Brevini slewing drives are suitable for the most severe duties in every environment. The design of the planetary units optimizes torque performance and radial load capacity, in order to give perfect meshing between pinion and ring gear. 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. DNV Type Approval certificate includes the complete range of Brevini Slewing Drives.
