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.

Fine Cyclo Speed Reducers are designed for robotic and other very demanding applications. These reducers emphasize zero backlash, extremely small lost motion and very high torsional stiffness to insure the ultimate in positioning accuracy. Because Fine Cyclo is based on the Cyclo speed reduction principals and technology, it withstands high shock loads, and boasts high reduction ratios in a small package.

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
- Medical equipment
