According to the tail gearbox structure of the internal combustion engine unmanned helicopter, a driving shaft is in transmission connection with a first bevel gear in a tripping mode, the service life of a tail rotor wing is greatly prolonged, the use and maintenance cost is reduced, and when the internal combustion engine unmanned helicopter flies in a complex environment, the service life of the tail rotor wing is greatly prolonged. When the rotating speed of the tail rotor exceeds the specified rotating speed, the main rotor is automatically disconnected from the tail rotor, the situation that the tail rotor pulls the main rotor is avoided, and stable flight of the internal combustion engine unmanned helicopter is ensured. The problems that when the internal combustion engine unmanned helicopter flies in a complex environment, the rotating speed of the tail rotor of the internal combustion engine unmanned helicopter exceeds the specified rotating speed, and the tail rotor pulls the main rotor, so that the service life of the tail rotor is shortened, and the later maintenance and use cost is high are solved.
本发明公开了一种内燃机无人直升机尾变速箱结构,通过驱动轴与第一锥齿轮可跳断地传动连接,大大提高了尾旋翼的寿命和降低了使用及维护成本,使得内燃机无人直升机在复杂环境中飞行时,当出现尾旋翼转速超过规定转速时将主旋翼自动与尾旋翼断开连接,不会导致尾旋翼拉扯主旋翼的情况,确保内燃机无人直升机的稳定飞行。本发明解决了在复杂环境中飞行时,内燃机无人直升机会出现尾旋翼转速超过规定转速,导致尾旋翼拉扯主旋翼,从而使得尾旋翼的使用寿命缩短,后期维护使用成本高的问题。
