Planetary Gearboxes Industrial

Foot mounted planetary gears

Foot mounted planetary gearsThese gearboxes are designed with mounting feet which are integrated into the gearbox housing. This 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 side range of accessories, including adaptors for electric and hydraulic motors.

Integral (cast) foot-mounted up to 20,000 lb.-ft. Fabricated feet up to 230,000 lb.-ft.


Shaft mounted planetary gears

Shaft mounted planetary gearsIn 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 planetary gears

Flange mounted planetary gearsBrevini'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.


Planetary gears for slewing drives

Planetary gears for slewing drivesBrevini'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 rations 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.

Models: RPR, SLS, SDU, standard series

Features Include:

  • Integral extended bearing support
  • Oversized spherical output bearing

Planetary winch drives

Planetary winch drivesPlanetary reduction gear units, with rotating outer casing, designed to be fitted into the winch drum. On the input side, they are equipped with a multidisc fail safe brake.

These winch drives give the freedom to design the rope drum and frame of any size and to incorporate any special features required. The driving motors, electrical or hydraulic, are fitted on the input side through the Brevini universal flange system.

Models: RPR, SLS, SDU, standard series

Features Include:

  • Integral extended bearing support
  • Oversized spherical output bearing
  • Standard gearing for quick turnaround
  • Disc (wet & dry) braking
