Introduction of planet carrier
planet carrier is one of the main components of planetary gear transmission device, and the planetary axle or bearing is installed on the planet carrier. When the planetary gear is used as the basic component, it is the part bearing external torque in the mechanism. The structural design and manufacture of planetary gears have a great impact on the load distribution between planetary gears and the bearing capacity, noise and vibration of transmission device
planet carrier characteristics
the reasonable structure of planet carrier should be light weight, good rigidity and easy to process and assemble. Its common structural forms include two-sided plate integral type, two-sided plate separate type and one-sided plate type. The integral type of bilateral plates has good rigidity. If integral forging is adopted for this structure, there will be a large amount of cutting. Therefore, the blank with structure and size close to the finished product can be obtained by casting and welding, but attention should be paid to eliminate casting or welding defects and internal stress. Whether the side will affect the strength, processing quality and deformation of planet carrier during use. The double side plate separated type is more complex than the overall structure, which is mainly used in the case of small transmission. Because the diameter of the planetary gear is small at this time, the planetary gear bearings are often installed on the wall plates on both sides of the planetary carrier, so that the outer diameter of the planetary carrier is greater than the diameter of the inner tooth top circle; The hole diameter in the center of the side plate of the planet carrier is smaller than that of the sun gear
processing technology design of planet carrier parts includes process design and process design of parts processing. In the process design, we should first analyze the parts, understand the process of the parts, then design the structure of the blank, select the machining benchmark of the parts, and design the process route of the parts
