A planetary gearbox is a type of gearbox that is used for high torque transmission within a small envelope. It is used in applications where space and weight are critical. The gearbox consists of several planet gears, which rotate around a central sun gear, thereby transmitting torque to the output shaft. The planetary gearbox has several advantages, including high torque density, compact size, and high efficiency.

Our planetary gearbox has the same installation dimensions as the Replacement of Brevini Riduttori brand, ensuring a high level of comparability in terms of performance parameters. Although we do not sell Replacement of Brevini Riduttori products, our ET3020 planetary gearbox is an ideal replacement for their products.

Each application requires a specific installation location and function for the planetary gearbox. For example, in construction machinery, the planetary gearbox is installed between the engine and the wheels or tracks to provide torque to the wheels or tracks. In petrochemical plants, the planetary gearbox is installed between the motor and the pump to provide torque to the pump.
It is essential to consider each parameter when replacing old gearboxes to find the perfect replacement. Output torque and reduction ratio are crucial to ensure that the new gearbox can handle the same load as the old one. Installation dimensions and input/output interface must match the old gearbox to ensure easy installation. Axial/radial load capacity is essential to ensure the new gearbox can handle the same loads as the old one. Input/output rotation direction must match the old gearbox to ensure proper operation. Rated power and operating temperature range must match the old gearbox to ensure maximum efficiency. Lubrication method and oil type must match the old gearbox to ensure proper lubrication. Noise and vibration standards must match the old gearbox to ensure quiet operation.
