Background Technology

[0002] Currently, yaw and pitch reducers are widely used in wind power generation. The reducer transmits power through gear transmission.

[0003] In actual assembly, the process of pressing the planetary gear assembly into the planet carrier column often lacks suitable installation tools, resulting in low assembly efficiency, frequent product quality problems, and the wide variety of planetary gear specifications, which increases the cost of installation tools and special fixtures and makes management inconvenient.

[0004] Specifically, the existing planetary gear assembly is currently installed in two ways: (1) pressing directly with a press, which cannot be positioned or clamped, and during the assembly process, due to the large pressure and the constraints of the planetary carrier structure, tilting and squeezing are likely to occur during the pressing process, resulting in defects such as scrapped parts and low assembly quality; (2) using the temperature difference method for assembly: heating the inner ring of the planetary gear assembly bearing and assembling it with the planetary shaft, but the temperature difference method has low assembly efficiency and high energy consumption.

[0005] Therefore, how to provide a positioning and installation fixture for planetary gear assemblies that can position the planetary carrier stop, provide reliable clamping and protection, and facilitate press-fitting with a hydraulic press has become a technical problem that urgently needs to be solved by those skilled in the art.
