14185517 Planetary Wheel I Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

Planetary Gear I (14185517), relying on professional gear manufacturing technology and strict quality control, is specially designed for the harsh working conditions of construction machinery. It is widely used in the gearboxes, slewing and traveling mechanisms of main models such as excavators, crawler cranes, and loaders. It is suitable for complex scenarios such as mining and infrastructure construction, effectively solving pain points such as tooth surface wear, tooth root breakage, and meshing jamming, helping to improve equipment efficiency and extend service life. It is the preferred component for aftermarket maintenance, foreign trade, and parts wholesale.
As a core meshing component of the transmission system, planetary gear I is made of high-quality alloy carburized steel, using precision hobbing and shaving processes, combined with multiple processes such as carburizing, quenching, and low-temperature tempering to improve tooth surface hardness and tooth profile accuracy. The tooth surface hardness is HRC60-64, and the tooth root hardness is HRC45-50, combining wear resistance and toughness, capable of withstanding heavy-load impacts, and preventing tooth surface spalling and tooth root breakage. The optimized involute tooth profile design reduces meshing impact and noise, precisely matches the installation dimensions, ensures accurate meshing with the planet carrier and sun gear, and is suitable for stable operation under long-term harsh working conditions.
