  • Product overview

The planetary carrier is one of the main components of the planetary gear transmission device, and the planetary gear shaft or bearing is installed on the planetary carrier.

When the planetary gear is used as the basic component, it is the component in the mechanism that bears a large external force moment. The structural design and manufacturing of planetary gears have a significant impact on the load distribution between various planetary gears, as well as the bearing capacity, noise, and vibration of the transmission device.

The reasonable structure of the planetary carrier should be light in weight, good in rigidity, and easy to process and assemble. There are three common structural forms of it: double-sided plate integral type, double-sided plate separate type, and single-sided plate type. The overall rigidity of both sides of the board is good. If the structure is integrally forged, the cutting amount is large. Therefore, casting and welding methods can be used to obtain blanks with structure and size close to the finished product. However, attention should be paid to eliminating casting or welding defect defects and internal stress, otherwise the strength, processing quality and use of the planet carrier may be affected.

The double-sided plate separation type has a more complex overall structure and is mainly used in situations where the transmission ratio is small. Due to the small diameter of the planetary gear at this time, the planetary gear bearings often need to be 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 aperture in the center of the planetary carrier side plate is smaller than that of the sun gear.

The company's main products include: automotive parts, diesel engine parts, engineering machinery parts, air compressor parts, die-casting machine consumables, and brake systems. It is a casting manufacturer that provides high-quality spare parts for the mechanical manufacturing industry.
