[0002] With the growing global demand for renewable energy, wind power generation has rapidly developed as a key component of clean energy. Offshore wind power, in particular, has garnered widespread attention in recent years due to its advantages, including more stable and stronger wind resources, as well as lower visual and noise pollution. In offshore wind turbines, the gearbox is a key component that converts the low-speed, high-torque generated by the rotor into the high-speed, low-torque required by the generator. Planetary gearboxes, due to their compactness and efficiency, are widely used in the design of large wind turbine gearboxes.

[0003] The machining accuracy of the planetary carrier in an offshore wind turbine gearbox directly affects the performance and life of the entire gear system. The planetary carrier typically requires several holes for mounting the planetary gears, and the position, size, and surface finish of these holes must be strictly controlled. Traditional machining methods often use a single three-sided milling cutter to machine both the upper and lower surfaces. After machining one surface, it rotates 180° and then machines the other surface, forming a through-hole planetary hole. However, this requires adjusting the milling cutter's position, resulting in low machining efficiency. Furthermore, the position and size of the planetary hole are also affected by the milling cutter's rotational accuracy. Summary of the Invention
