【摘要】 风电是实现碳达峰、碳中和目标的重要能源形式。风电机组运行一段时间后，其发电机轴的轴颈容易出现磨损。为实现轴颈的高效可靠修复，提出一种在线镶套修复工艺。该工艺对磨损的轴颈进行车削，随后将轴套安装于轴颈上，使二者过盈配合。对修复工艺进行了介绍，重点计算了镶套过程的关键工艺参数，确保修复后的轴颈的尺寸精度满足要求。工程应用表明，该工艺可以在短时间内修复磨损的轴颈，效率高、质量好，有助于提高风机的发电量和风场的经济性。相关研究成果可为我国风电行业的健康发展提供参考。更多还原

【Abstract】 Wind power is an important energy form to achieve the goal of carbon peak and carbon neutralization. The journal of the generator axle journal is easy to be worn after the wind turbine runs for a period of time. In order to achieve efficient and reliable repair, an on-line repair process was proposed. In this process, the worn axle journal was turned, and then the axle sleeve was installed on the axle journal to make their interference fit. In this paper, the repair process was introduced, and the key process parameters of the inserting sleeve process were calculated, ensure that the dimensional accuracy of the repaired axle journal met the requirements. The engineering application showed that the worn axle journal was repaired with high efficiency and good quality, which was helpful to improve the power generation of the wind turbine and the economy of the wind farm. Relevant research results may provide reference for the healthy development of China’s wind power industry.更多还原
