摘　　要：再制造是一种对废旧产品实施技术修复和改造,并使其性能恢复甚至超过新品的绿色生产模式。长输管线用压缩机转子的叶轮与主轴间的过盈量设计时高达(1.7～2.2)‰,在再制造拆解环节中,配合面易产生划伤、粘着、犁沟等拆解界面损伤,为再制造带来额外的修复工作。配合长度愈大,损伤也愈趋严重。为此,提出了一种面向再制造的压缩机转子过盈配合优化设计方法。在对现有压缩机转子过盈结构进行数值分析的基础上,结合转子服役需求与静摩擦实验结果,对配合长度进行了优化。此外,为进一步降低拆解损伤,在保障服役需求的前提下,对配合界面进行了再制造织构设计。Remanufacturing is a new kind of green production mode, which can be used to repair and reconstruct the waste products, and make its performance even more than new products. The interference between long-distance pipeline compressor’s rotor impeller with main spindle is up to(1.7~2.2)‰. It is easy to produce scratches, adhesions, furrows and other dismantling interface damage in the process of remanufacturing. It will make additional remanufacturing repairing work. The larger of interference fit, the more serious the damage is. For that reason, an optimized design method of interference fit for the compressor rotor facing remanufacturing is proposed in this paper. Fit length was optimized in this method, which is on the basis of the existing numerical analysis with the interference structure of compressor rotor, combined with the rotor service requirements and static friction test results. In order to further reducing the damage of dismantling, the remanufacturing texture design is carried out on the premise of ensuring the service demand.
