The structural design and manufacture of the planet wheels has a great influence on the load distribution among the planet wheels, so that the bearing capacity, noise, vibration and the like of the transmission device are greatly influenced. The reasonable structure of the planet carrier should be light in weight, good in rigidity and convenient to process and assemble. The common structural forms of the composite plate include a double-side-plate integral type, a double-side-plate split type and a single-side-plate type. The double-side-plate integral type planet carrier has good rigidity, so that the double-side-plate integral type planet carrier is often used for the situations with high rigidity requirements, such as transmissions and the like.
The existing integral planet carrier has two manufacturing methods, namely a casting and welding method and integral forging. However, the former has the technical problems that the strength of the planet carrier is not high and the planet carrier is easy to deform in use due to casting or welding defects and internal stress, and the latter has the technical problems of high difficulty in cutting and processing and complex processing procedures.
Therefore, how to further simplify the structure of the planet carrier and how to further reduce the processing amount is a problem to be solved by technicians in the industry, and an integral planet carrier structure is designed for the purpose.
