Planetary Gearbox Reducer Replacement of Brevini Riduttori EQ4020
Planetary Gearbox Reducer Replacement of Brevini Riduttori EQ4020
A planetary gearbox is a type of gearbox that consists of a central sun gear, an outer ring, and planetary gears that rotate around the central sun gear and mesh with the outer ring. This design allows for high torque transmission with a compact size, making it popular in various industrial applications.
Features of Planetary Gearbox Reducer Replacement of Brevini Riduttori EQ4020
- High torque transmission: The EQ4020 model can handle up to 4900 Nm of output torque.
- Compact size: With a reduction ratio of up to 700:1, the EQ4020 model is a highly efficient and compact solution for industrial machinery.
- Double reduction stages: The EQ4020 model uses two reduction stages to achieve a higher reduction ratio, providing more flexibility in industrial applications.
- Flexible mounting options: The EQ4020 model can be mounted in any position, providing greater flexibility in installation.
- Smooth operation: The EQ4020 model uses high-quality bearings and gears, ensuring smooth and quiet operation.


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

Applications of Industry Series Planetary Gearbox
- Robotics: Planetary gearboxes are commonly used in robotic arms for high precision and torque transmission.
- Mining machinery: Planetary gearboxes can be used in mining conveyor belts for high torque and reduced maintenance.
- Wind turbines: Planetary gearboxes are used in wind turbines to transmit the low speed, high torque rotation of the blades to the high speed, low torque rotation of the generator.
- Construction machinery: Planetary gearboxes are used in various construction machinery, such as concrete mixers and excavators, for their high torque and compact size.
Planetary gearboxes can be installed in various parts of industrial machinery depending on the specific application. In robotic arms, for example, planetary gearboxes are typically installed near the joints to provide high precision and torque transmission. In mining conveyor belts, they are often used near the motor to reduce maintenance.
Parameters for Replacing Old Planetary Gearboxes
When replacing old planetary gearboxes, it is important to consider the following parameters:
- Output torque: The output torque of the new gearbox should match or exceed that of the old one.
- Reduction ratio: The reduction ratio should be compatible with the application's requirements.
- Installation dimensions: The new gearbox should have the same installation dimensions to ensure compatibility.
- Input/output interface: The new gearbox should have the same input/output interface as the old one.
- Axial/radial load capacity: The new gearbox should have a load capacity that matches or exceeds that of the old one.
- Input/output rotation direction: The new gearbox should have the same input/output rotation direction as the old one.
- Rated power: The rated power of the new gearbox should match or exceed that of the old one.
- Operating temperature range: The new gearbox should have an operating temperature range that matches the application's requirements.
- Lubrication method and oil type: The new gearbox should use the same lubrication method and oil type as the old one.
- Noise and vibration standards: The new gearbox should meet the application's noise and vibration standards.
It is important to ensure that all parameters are met to ensure proper compatibility and performance.
Signs that a New Planetary Gearbox is Needed
- Increased noise: If the gearbox is making more noise than usual, it may be a sign that the gears are worn or damaged.
- Reduced torque: If the gearbox is not providing the same level of torque as before, it may be a sign of wear or damage.
- Leaking oil: If there is oil leaking from the gearbox, it may be a sign of a damaged seal or gasket.
- Increased vibration: If the gearbox is vibrating more than usual, it may be a sign that the gears are worn or damaged.
- Stuck gears: If the gears are stuck or difficult to move, it may be a sign of wear or damage.
