The invention discloses a power and transmission system of an electric coaxial dual-rotor unmanned helicopter, which belongs to the technical field of power and transmission of helicopters.The power and transmission system of the electric coaxial dual-rotor unmanned helicopter comprises a non-rotating main shaft connected to a helicopter body structure, and the upper end and the lower end of the non-rotating main shaft are each sleeved with a fluted disc sleeve; the ends, away from the center of the non-rotating main shaft, of the two fluted disc sleeves are each connected with a rotor wing rotating propeller hub, the two fluted disc sleeves are each connected with a transmission mechanism, the transmission mechanisms are connected with a driving mechanism, the driving mechanism drives the transmission mechanisms to rotate, then the fluted disc sleeves are driven to rotate, and then the rotor wing rotating propeller hubs are driven to rotate. The driving of the electric coaxial dual-rotor unmanned helicopter is realized; the driving mechanism connected with the upper fluted disc sleeve is arranged downwards, the driving mechanism connected with the lower fluted disc sleeve is arranged upwards, and the two driving mechanisms are arranged in a central symmetry mode around the center of the non-rotating main shaft.

    本发明公开了一种电动共轴双旋翼无人直升机的动力与传动系统,属于直升机的动力与传动技术领域,包括连接在机体结构上的不旋转主轴,在不旋转主轴的上下两端各套有一个齿盘套筒,两个齿盘套筒远离不旋转主轴中心的一端各连接一个旋翼旋转桨毂,两个齿盘套筒上分别连接传动机构,传动机构连接驱动机构,通过驱动机构带动传动机构转动,进而带动齿盘套筒转动,进而带动旋翼旋转桨毂旋转,实现对电动共轴双旋翼无人直升机的驱动;上方的齿盘套筒连接的驱动机构朝下设置,下方的齿盘套筒连接的驱动机构朝上设置,两个驱动机构绕不旋转主轴的中心呈中心对称设置,本发明能够减轻直升机重量,减少电磁干扰,合理利用空间进行系统布局。
