A propulsion system power transmission shaft comprises a basic shaft, work pieces and fixing bolts, the basic shaft and the work pieces are connected and fixed through the fixing bolts, an input flange of the basic shaft is provided with a mounting hole, the mounting hole comprises a force bearing area and a fixing area, and the fixing area is provided with a limiting hole used for fixing of the fixing bolts. The work piece is in a boss shape and comprises a force bearing section and a fixed wing, a reamed hole is formed in the force bearing section, and a stepped hole and a jackscrew hole are formed in the fixed wing and used for matched installation and detachment. Under the scene that some transmission shafts need to be repeatedly used, the transmission shafts cannot be assembled for the second time after being reamed, and new transmission shafts need to be customized again to meet the reaming requirement. The work piece and the basic shaft are combined to form the transmission shaft, only the reamed hole of the work piece needs to be reamed during reaming, when the work piece needs to be reused, the transmission shaft can be redrilled by replacing the work piece, and compared with a transmission shaft body, the work piece is low in cost, short in manufacturing time and easy to replace and has good economic benefits.
一种推进系统功率传动轴,包括基础轴、工作件、固定螺栓,基础轴与多个工作件利用固定螺栓连接固定,基础轴输入法兰设有安装孔,安装孔包括承力区和固定区,所述固定区设有限位孔,用于固定螺栓固定。所述工作件为凸台形状,包括承力段和固定翼,在承力段设有铰制孔,固定翼设有台阶孔和顶丝孔,用于配套安装和拆除。一些传动轴需要重复使用场景下,传动轴铰孔使用后则无法进行第二次装配,需要重新定制新的传动轴以满足铰孔需求。工作件与基础轴结合构成传动轴,铰孔时仅需要对工作件的铰制孔进行铰孔,当需要重新使用时,更换工作件,即可对传动轴重新铰孔,工作件与传动轴本体相比成本低,制造时间短,更换简单,具有良好的经济效益。
