After planetary carrier

This is a rear planetary carrier for RV gear reducers, made of 40Cr alloy structural steel. It is a precision metal component in the form of a disc with raised bosses, serving as a core part within the reducer that enables planetary gearing. Featuring both high strength and excellent wear resistance, it is well-suited for heavy-duty, high-precision transmission applications such as industrial automation and robotic joints.

    On the left is a photograph of the actual part: a silver-gray, metal, disc-shaped component, which is… After planetary carrier The surface features six cylindrical bosses with internal bores evenly distributed, along with three larger circular through-holes. The overall structure is compact, with a smooth finish that exudes the metallic texture of precision machining—typical of a reducer’s transmission component.

     
    2. Core Parameters
     
    • Name : Rear planetary carrier
    • Material : 40Cr (a medium-carbon alloy structural steel that, after quenching and tempering, exhibits high strength, toughness, and wear resistance, and is widely used in heavy-duty transmission components)
    • Application scenarios : RV reducer (a precision gearbox commonly used in robot joints and automated equipment; the planetary carrier is its internal core transmission component, responsible for transmitting torque and providing support and motion for the planetary gears)

     

    3. Design Details

     

    The cylindrical boss of the component is designed to mount the planetary gear shaft, while the through-hole facilitates assembly and positioning. This structural design ensures smooth meshing of the planetary gears during reducer operation, enabling them to withstand high torque and impact loads. It is one of the key components that enables RV reducers to deliver high precision and large reduction ratios.
