| The Sumitomo Cyclo drive is unsurpassed by any other inline drive available in the market today. Cyclo's unique epicycliodal design has advantages superior to speed reducers using common involute tooth gears. Cyclo components operate in compression, not in shear. Unlike gear teeth with limited contact points, a Cyclo has two thirds of its reduction components in contact at all times. This design enables Cyclo speed reducers and gearmotors to withstand shock loads exceeding 500% of their ratings, and provide exceptional performance, reliability and long life in the most severe applications. |

The PPG precision planetary gear is characterized by three major design advantages:
PPG load compensation ensures minimized friction for smooth running and for outstandingly high synchronizing, and last but not least, a long service life.
The PPG compensating coupling has a unique, space-saving angle error compensation feature. The low mass moment of inertia ensures high motive response. The coupling operates without backlash, with high rigidity and has length compensation.
The friction optimized PPG seals ensure a lower starting inertie.
The thermal load limit is very high due to low friction losses.
Applications:
- Gantry robots
- Positioning systems for robots
- Automating production
- Manufacturing semiconductors
- Machine tools
- Loading/unloading machines
- Packaging machinery
- Woodworking

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. |

WHEEL DRIVES
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).
TRACK DRIVES
Compact planetary track drive units designed for use on tracked vehicles. 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. |

Planetary 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 failsafe 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. |
|
| Rotating case gearboxes, complete with static negative disc brakes, offer the best of both our planetary gearboxes and hydraulic lifting winches. Nominal output torque values range from 4.000 Nm to 50.000 Nm. |
|
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). |
