The invention discloses a driving shaft structure suitable for a nuclear power commercial ship driving device, which comprises an input driving unit, an output driving unit and a plurality of middle driving units, the plurality of middle driving units are divided into two groups, the middle driving units in one group are uniformly arranged at intervals along a first direction, and the middle driving units in the other group are uniformly arranged at intervals along a second direction. The middle driving units in one group are evenly arranged at intervals in the first direction, the middle driving units in the other group are evenly arranged at intervals in the second direction, the first direction and the second direction are parallel and offset, the middle driving units in the two groups are distributed in a staggered mode, and the adjacent ends are in transmission connection; and the output driving unit is in transmission connection with the middle driving unit at the other end. Through the combination of a plurality of driving units, the driving effect of a long shaft can be realized, meanwhile, due to the adoption of a short shaft form, the inherent frequency of each section of driving shaft is improved, the possibility of generating flutter and even resonance is avoided, and the maintenance is convenient and the cost is low after the driving shaft breaks down.
本发明公开了一种适用于核动力商船驱动装置的驱动轴结构,包括输入驱动单元、输出驱动单元和多个中间驱动单元,所述多个中间驱动单元分成两组,其中一组中的中间驱动单元沿第一方向均匀间隔布置,另一组中的中间驱动单元沿第二方向均匀间隔布置,所述第一方向与所述第二方向平行且偏移设置,两组中的中间驱动单元错位分布且相邻的端部传动连接,所述输入驱动单元与一端的中间驱动单元传动连接,所述输出驱动单元与另一端的中间驱动单元传动连接。通过多个驱动单元组合,不仅可以实现长轴的驱动效果,同时由于采用了短轴形式,提高了各节驱动轴的固有频率,避免了产生颤振甚至共振的可能性,而且在驱动轴故障后维修方便且成本低。
