Abstract:
The manufacturing quality and technology of gearbox, which is a core component, is the key guarantee for the superior performance of wind turbine. Wind turbine gearbox manufacturing is a comprehensiveness technique involved multiple disciplines. To realize the digital lean manufacturing, the in-depth research on the fundamental process theory and the process control method should be carried out by taking full advantage of the existing techniques. Also, some new technologies, new processes and new materials should be investigated and applied. By considering the structural features and the actual operational condition for wind turbine gearbox and combining production practices, the requirements and characteristics of the process techniques are summarized. The research state, existing problems, applications and development tendency of high-performance wind turbine gear manufacturing, housing manufacturing and planet carrier manufacturing are analyzed. Then some methods are proposed to improve the manufacturing efficiency and control the heat treatment deformation. Finally, the test techniques for wind turbine are introduced. It has project practical significance for the manufacturing of wind turbine gearboxes.
