I. Detailed Description
1. Product Appearance
On the left is a photograph of the actual part: a silver-gray, metal, disc-shaped component, which is… Pre-planetary framework The surface features six small locating holes evenly distributed, with three larger circular through-holes in the central area. The overall structure is symmetrical and well‑proportioned, and the finish exhibits a finely machined metallic texture—typical of a reducer’s transmission component.
2. Core Parameters- Name : Pre-planetary framework
- Material : 40Cr (a medium-carbon alloy structural steel that, after quenching and tempering, exhibits high strength, good toughness, and excellent wear resistance; widely used in heavy-duty transmission components)
- Application scenarios : RV reducer (a precision gearbox commonly used in industrial robot joints and automation equipment; its internal core transmission component is the front planetary carrier, which supports the planet gears, transmits torque, and achieves reduced-speed motion)
3. Functions and Design Details
The locating holes in this component are used to mount the planetary gear shaft and securing bolts, while the central through-hole facilitates power transmission or shaft‑assembly. This symmetrical structural design ensures smooth meshing of the planetary gears during reducer operation, enabling them to withstand high torque and impact loads. In conjunction with the rear planet carrier, it forms a complete planetary gear train and serves as one of the key components that enable RV reducers to deliver high precision and large reduction ratios.
