The invention belongs to the technical field of helicopter transmission system design, and discloses a multi-fulcrum ultra-long helicopter necking tail transmission shaft and an assembling method thereof. Comprising a tail shaft tube, a plurality of bearing assemblies installed on the tail shaft tube and connector structures connected with the two ends of the tail shaft tube. A necking structure is arranged at one end of the tail shaft tube; the plurality of bearing assemblies are respectively mounted at preset fulcrum positions of the tail shaft tube through the necking structures; and at least one of the joint structures connected with the two ends of the tail shaft tube is of a spline structure. Therefore, the multi-fulcrum ultra-long helicopter necking tail transmission shaft is formed. And a new configuration of the helicopter tail transmission shaft design is expanded.

    本发明属于直升机传动系统设计技术领域,公开了一种多支点超长直升机缩颈尾传动轴及其装配方法。包括:尾轴轴管、安装在尾轴轴管上的多个轴承组件以及与尾轴轴管两端连接的接头结构;所述尾轴轴管一端设置有缩颈结构;所述多个轴承组件分别通过所述缩颈结构安装在尾轴轴管的预设的支点位置;所述与尾轴轴管两端连接的接头结构中至少一个为花键结构。形成了一种多支点超长直升机缩颈尾传动轴。拓展了直升机尾传动轴设计的新构型。
