[0002] A compound planetary gearbox is a multi-stage gear transmission device that combines a planetary gear train and a fixed-axis gear train. It combines the advantages of both transmission methods and has the characteristics of large transmission ratio, high transmission efficiency and small size. It is widely used in the transmission systems of large and complex mechanical equipment, such as wind turbines, gas turbine power generation, compressors and other fields.

[0003] A planetary gearbox consists of a planetary gear train, a fixed-axis gear train, and seals. The planetary gear train includes the sun gear, planet gears, a planet carrier, and an internal ring gear. The sun gear is located at the center, and the planet gears orbit and rotate around it.
