A pre-inclined propeller lift device is characterized in that a front inclined motor is connected to a front inclined motor mounting seat of a double-inclined-surface motor seat, a rear inclined motor is connected to a rear inclined motor mounting seat of the double-inclined-surface motor seat, a front inclined bevel gear is connected with the front inclined motor, and a rear inclined bevel gear is connected with the rear inclined motor; the front inclined bevel gear is meshed with the rear inclined bevel gear, the front inclined propeller is connected with the front inclined bevel gear, the rear inclined propeller is connected with the rear inclined bevel gear, the front inclined propeller and the rear inclined propeller are propellers of the same size, the front inclined propeller and the rear inclined propeller are equal in rotating speed and opposite in rotating direction, and reaction torques of the front inclined propeller and the rear inclined propeller are mutually counteracted; the forward-inclined propeller which is pre-inclined forwards increases the component force of lift force in the horizontal direction, the forward-inclined propeller is applied to the multi-propeller unmanned aerial vehicle, the efficiency of the forward-inclined propeller is improved, the driving force in the horizontal direction is increased, and the lift force in the horizontal direction is increased. The flight speed and the load capacity are improved.

    一种预倾斜螺旋桨升力装置,前倾斜电机连接在双斜面电机座的前斜面电机安装座上、后倾斜电机连接在双斜面电机座的后斜面电机安装座上,前倾斜锥齿轮连接前倾斜电机,后倾斜锥齿轮连接后倾斜电机,前倾斜锥齿轮齿合后倾斜锥齿轮,前倾斜螺旋桨连接前倾斜锥齿轮、后倾斜螺旋桨连接后倾斜锥齿轮,前倾斜螺旋桨和后倾斜螺旋桨是尺寸相同的螺旋桨,前倾斜螺旋桨和后倾斜螺旋桨转速相等、转向相反、反扭矩相互抵消;前倾斜螺旋桨向前倾斜与水平面的夹角α等于后倾斜螺旋桨向后倾斜与水平面的夹角β,向前预倾斜的前倾斜螺旋桨增大了升力在水平方向的分力,应用于多螺旋桨无人机,提高了前倾斜螺旋桨的效率,增大水平方向驱动力,提高飞行速度和载重量。
