The reasonable structure of the planet carrier should be light weight, good rigidity, and easy to process and assemble. Its common structural forms are three types: double-sided plate integral type, double-sided plate split type and single-sided plate type. The integral rigidity of both side plates is good. This type of structure requires a large amount of cutting if it is forged integrally. Therefore, casting and welding methods can be used to obtain a blank with a structure and size close to the finished product. However, care should be taken to eliminate casting or welding defects and internal stress. Whether or not it will affect the strength of the planet carrier, Deformation may occur during processing quality and use. The split type of the double side plate is more complicated than the overall structure, and is mainly used in the case of relatively small transmission. Due to the small diameter of the planet gear at this time, the planet gear bearings are often installed on the two side plates of the planet carrier, so that the outer diameter of the planet carrier is larger than the diameter of the internal tooth tip circle; the center hole diameter of the side plate of the planet carrier is smaller than the sun gear.
The star carrier is one of the main components of the planetary gear transmission, and the planet wheel shaft or bearing is mounted on the planet carrier. When the planetary wheel is used as the basic component, it is the part in the mechanism that is subjected to external torque. The structure design and manufacturing of the planetary gears have a great impact on the load distribution between the planetary gears and the bearing capacity, noise and vibration of the transmission.
