Planetary Gearbox Reducer Replacement of Brevini Riduttori EC4090
Planetary Gearbox Reducer Replacement of Brevini Riduttori EC4090
A planetary gearbox, also known as an epicyclic gearbox, is a type of gearbox that utilizes a planet and sun gear to transmit torque and reduce rotational speed. This type of gearbox is commonly used in industrial applications where high torque and precision are required.
Features of Planetary Gearbox Reducer Replacement of Brevini Riduttori EC4090
- High torque capacity, up to 1,000 Nm
- High precision, with backlash as low as 1 arcmin
- High efficiency, up to 97%
- Compact design, with a small footprint and low weight
- Reliable performance, with a long service life and low maintenance requirements

Our planetary gearbox replacement for Brevini Riduttori EC4090 has the same installation dimensions as the Brevini Riduttori product, ensuring high comparability of performance parameters and making it an ideal replacement for Brevini Riduttori. Please note that we do not sell Brevini Riduttori products and only mention this model for customer convenience.

Applications of Industry Series Planetary Gearbox
- Construction machinery - used in excavators, loaders, and cranes for precise and powerful lifting and digging
- Marine industry - used in propulsion systems and winches for reliable and efficient operation in harsh marine environments
- Mining industry - used in crushers, mills, and conveyors for high torque and precision control
- Renewable energy - used in wind turbines and solar trackers for precise and efficient power generation
- Agricultural machinery - used in tractors and harvesters for reliable and efficient operation in tough agricultural conditions
Each application of the planetary gearbox has a specific installation location and functional requirement. For example, in an excavator, the planetary gearbox is installed in the hydraulic motor and is responsible for transmitting torque to the digging arm. In a wind turbine, the gearbox is installed between the rotor and the generator and is responsible for increasing the speed of the slow-moving rotor to generate electricity.
Parameters for Replacing Old Planetary Gearbox
When replacing an old planetary gearbox, it is important to consider the following parameters:
- Output torque
- Reduction ratio
- Installation dimensions
- Input/output interface
- Axial/radial load capacity
- Input/output rotation direction
- Rated power
- Operating temperature range
- Lubrication method and oil type
- Noise and vibration standards
Each parameter plays an important role in the performance and compatibility of the new planetary gearbox. For example, if the output torque of the new gearbox is lower than the old one, it may not be able to handle the application's requirements. Similarly, if the installation dimensions are different, the new gearbox may not fit into the existing system.
Signs to Replace Old Planetary Gearbox
- Increased noise or vibration
- Reduced efficiency or output power
- Leakage of lubricant or other fluids
- Damaged gears or other components
- Excessive wear or corrosion
If any of these signs are present, it may be time to replace the old planetary gearbox to ensure reliable and efficient operation.
