The driving device is used for being connected with a main rotor wing and a tail rotor wing and comprises a driving motor, a transmission shaft and a transmission disc, the driving motor comprises a rotor and a stator, the stator is rotationally connected with a mounting cylinder, the rotor is arranged on the mounting cylinder in a sleeving mode through a one-way bearing, and the rotor is arranged on the stator in a sleeving mode; the transmission shaft penetrates through the mounting cylinder and is used for being connected with a main rotor, the mounting cylinder is sleeved with the transmission disc, the transmission disc is used for being connected with a tail rotor, and the rotor can rotate to drive the mounting cylinder to rotate so as to drive the transmission shaft and the transmission disc to rotate. By means of the structure, after the driving motor is braked, the main rotor continuously rotating due to rotation inertia cannot drive the rotor to rotate due to the arrangement of the one-way bearing, and therefore the service life of the driving motor can be prolonged.
本发明公开了一种驱动装置以及直升机,其中,一种驱动装置用于与主旋翼和尾旋翼连接,其包括驱动电机、传动轴以及传动盘,驱动电机包括转子和定子,定子转动连接有安装筒,转子通过单向轴承套设于安装筒,且转子套设于定子,传动轴穿设于安装筒,传动轴用于与主旋翼连接,传动盘套设于安装筒,传动盘用于与尾旋翼连接,其中,转子能够转动驱使安装筒转动,以带动传动轴和传动盘转动。通过上述结构,单向轴承的设置能够在制停驱动电机后,使因旋转惯量继续转动的主旋翼不会带动转子转动,因此,能够延长驱动电机的使用寿命。
