Planetary Gearbox Reducer Replacement of Brevini Riduttori EC3155

Planetary Gearbox Reducer Replacement of Brevini Riduttori EC3155

A planetary gearbox, also known as an epicyclic gearbox, is a type of gearbox that uses one or more outer gears, also known as planet gears, revolving around a central sun gear to transmit torque and rotation. It has the ability to increase or decrease rotational speed and transmit torque efficiently, making it ideal for industrial applications.

Features of Planetary Gearbox Reducer Replacement of Brevini Riduttori EC3155

  • High Efficiency: The planetary gearbox replacement of Brevini Riduttori EC3155 has a high efficiency, with minimal energy loss during transmission.
  • Compact Design: Its compact design allows it to take up less space and fit into tight spaces without sacrificing performance.
  • Quiet Operation: It operates quietly and smoothly, minimizing noise and vibration levels in industrial settings.
  • High Load Capacity: The planetary gearbox has a high load capacity, making it suitable for heavy-duty applications.
  • Durable: It is made with high-quality materials and designed for long-term use, even in harsh environments.


Our planetary gearbox has the same installation dimensions as Brevini Riduttori's, ensuring high comparability of performance parameters. It is an ideal replacement for Brevini Riduttori's product. Please note that we do not sell Brevini Riduttori's products, and we only mention their model number for customer convenience.

Applications of Industry Series Planetary Gearbox

  • Robotics: The planetary gearbox is an essential component of industrial robots, providing high precision and accuracy in motion control systems.
  • Material Handling: It is used in conveyor belts, cranes, and other material handling equipment to provide smooth and efficient movement of goods.
  • Agriculture: The planetary gearbox is used in farming equipment such as tractors, harvesters, and irrigation systems to provide power and torque for various agricultural tasks.
  • Construction: It is used in construction equipment such as excavators, bulldozers, and loaders to provide power and speed control for various tasks.
  • Marine: The planetary gearbox is used in marine applications such as propeller systems, winches, and steering systems to provide torque and speed control in marine environments.

Each application requires a specific installation position and function of the planetary gearbox. For example, in a crane, the planetary gearbox is installed between the motor and the hoist drum to provide torque and speed control for lifting and lowering loads.

Parameters for Replacing Old Planetary Gearbox

When replacing an old planetary gearbox, it is important to consider the following parameters:

  • Output Torque: The output torque of the new gearbox should be equal to or greater than that of the old gearbox.
  • Reduction Ratio: The reduction ratio determines the output speed of the gearbox. It should match the needs of the application.
  • Installation Dimensions: The new gearbox should have the same installation dimensions as the old gearbox for compatibility.
  • Input/Output Interfaces: The new gearbox should have the same input and output interfaces as the old gearbox for compatibility.
  • Axial/Radial Load Capacity: The new gearbox should have the same or greater axial and radial load capacity as the old gearbox.
  • Input/Output Rotation Direction: The new gearbox should have the same input and output rotation direction as the old gearbox for compatibility.
  • Rated Power: The rated power of the new gearbox should match the requirements of the application.
  • Operating Temperature Range: The new gearbox should operate within the temperature range required by the application.
  • Lubrication Method and Oil Type: The lubrication method and oil type of the new gearbox should match the requirements of the application.
  • Noise and Vibration Standards: The new gearbox should meet the noise and vibration standards required by the application.

Any signs of wear and tear, such as abnormal noise or vibrations, oil leaks, or reduced output performance, are indications that a new gearbox is needed.
