The invention discloses a tilting type coaxial rotor helicopter with a controllable rotor shaft, which comprises a main rotor shaft connected with a helicopter. The outer side wall of the protective sleeve is sleeved with a lower rotor device, the top of the protective sleeve is connected with a control panel through an angle adjusting device, the control panel is rotationally connected with an upper rotor shaft, the top of the upper rotor shaft is connected with an upper rotor through a connecting piece, the upper rotor shaft is connected with the main rotor shaft through a shaft guiding device, and a lifting force adjusting device is arranged on the control panel. Under the combined action of a push rod motor, a rotating gear, a lead screw column, a vertical column and a connecting ball,the inclination of the angle of the upper rotor shaft is realized; the upper rotor shaft and the main rotor shaft are connected; the lower driving rod, the limiting arc-shaped piece, the guide ball and the upper driving rod are connected, so that when angle inclination is generated, the main rotor shaft can drive the upper rotor shaft to rotate through position angle compensation of all components at the guide ball, and normal transmission and normal rotation of the upper rotor are guaranteed.

    本发明公开了旋翼轴可控倾转式共轴旋翼直升机,包括与直升机连接的主旋翼轴,防护套外侧壁套设有下旋翼装置,防护套顶部通过角度调整装置连接有控制盘,控制盘转动连接有上旋翼轴,上旋翼轴顶部通过连接件连接有上旋翼,上旋翼轴与主旋翼轴之间通过轴导向装置连接,控制盘上设置有升力调整装置。本发明通过推杆电机、旋转齿轮、丝杠柱、竖直柱、连接球的共同作用下,实现将上旋翼轴的角度进行倾斜,通过将上旋翼轴与主旋翼轴之间的连接方式,通过下驱动杆、限位弧形件、导向球和上驱动杆进行连接,使得在产生角度倾斜时,也能通过导向球处各部件的位置角度补偿实现主旋翼轴带动上旋翼轴进行转动,保证传动的正常,上旋翼的正常旋转。
