The invention discloses a tilting propeller device of a helicopter, belongs to the technical field of helicopter instrument production, and aims to solve the technical problem of how to provide a propeller device which is not provided with a hinge structure and can generate lift force and thrust force for the helicopter. According to the technical scheme, a long shaft and a short shaft are installed at the two ends of a framework of a cross-shaped annular track and on the outer side of the track respectively, a large gear and a bearing are installed on the long shaft, a bearing is installed on the short shaft, and a small gear of a tilting motor is meshed with the large gear to control tilting of the annular track. The motor is mounted above the center of the cross-shaped annular track and at the lower end of the transmission shaft and below the track, the turntable is provided with a plurality of paddles and rollers, and the rollers are in contact with the lower part of the annular track; lift force is generated when the blades rotate, the lift force is transmitted to the helicopter body through the idler wheels, the annular track and the supporting frame to provide lift force for the helicopter, and forward thrust can be generated when the propellers tilt. The propeller device is suitable for helicopters and vertical take-off and landing unmanned aerial vehicles.

    一种直升机的倾转螺旋桨装置,属于直升机器械生产技术领域,所要解决的技术问题:如何为直升机提供一种没有铰链结构、既能产生升力、又能产生推力的螺旋桨装置。技术方案要点是:十字环形轨道一个骨架两端、轨道外侧,各安装一个长轴和短轴,长轴上安装大齿轮和轴承,短轴上安装轴承,倾转电机的小齿轮与大齿轮啮合,控制环形轨道倾转。电机安装在十字环形轨道中心上方,传动轴下端、轨道下方安装转盘,转盘上安装多个桨叶和滚轮,滚轮与环形轨道下方接触;桨叶旋转时产生升力,升力通过滚轮、环形轨道、支撑架传递给机身,为直升机提供升力,螺旋桨倾转时可产生向前的推力。该螺旋桨装置适用于直升机和垂直起降无人机。
