The invention discloses a variable-pitch folding propeller collecting device which comprises a propeller seat, a variable-pitch propeller shaft, a propeller, a propeller sleeve, a collecting and releasing transmission rod, a rotary collecting and releasing transmission ring, a translation collecting and releasing transmission ring, a power base pipe, a collecting and releasing rotation synchronous system, a propeller collecting brake system, a collecting and releasing driving system and a variable-pitch driving system. According to the folding propeller folding device with the variable propeller pitch, the variable pitch function is added on the basis of the basic function of common propeller folding, propeller pitch control can be conducted when the propeller is unfolded, the control force of an airplane is improved, and meanwhile normal folding and unfolding actions of the propeller are not affected.

    本发明公开了一种可变桨距的折叠收桨装置,包括包括桨座,变距桨轴,螺旋桨,桨套,收放传动杆,旋转收放传动环,平移收放传动环,动力基座管,收放旋转同步系统,收桨刹车系统,收放驱动系统,变距驱动系统。本发明提供的一种可变桨距的折叠收桨装置,在普通收桨的基础功能上,增加变距功能,使螺旋桨在展开时可以进行桨距控制,提高飞机的控制力,同时不影响螺旋桨正常的收起展开动作。
