FLANGE MOUNTED 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. Technical Data Torque (T2max) Nm: up to 900.000 Transmission Ratio: up to 3.150 iN Power Rating kW: up to 720

SHAFT MOUNTED 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).
