The invention discloses a multi-blade cycloid propeller adopting a control shaft plane position decoupling mechanism. The multi-blade cycloid propeller comprises a base, a gear set mechanism, a lineardriving mechanism and a guide rod sliding block mechanism. At least three blades which are symmetrically arranged by taking the main shaft as the center are arranged below the base; the guide rod sliding block mechanism comprises guide rods connected with the blades, sliding blocks sliding along the guide rods are arranged on the guide rods in a sleeving mode, the sliding blocks are sequentiallyhinged in the height direction, and a control shaft eccentrically arranged relative to the main shaft is formed by connecting lines of the gravity centers of the sliding blocks. The fixed end of the linear driving mechanism is provided with a hinge point rotating around the spindle, and the movable end is hinged to a slider in the guide rod slider mechanism at the position of the control shaft andused for adjusting the radial position of the control shaft relative to the spindle. The gear set mechanism is connected with the linear driving mechanism and used for adjusting the circumferential position of the control shaft relative to the main shaft. The position of the control shaft of the cycloid propeller can be changed at will, and the motion mechanism of the cycloid propeller is accurately achieved.
本发明公开了一种采用控制轴平面位置解耦机构的多叶片摆线推进器,包括基座、齿轮组机构、直线驱动机构以及导杆滑块机构;基座下方设置至少三个以主轴为中心对称布置的叶片;导杆滑块机构包括与各叶片连接的导杆,各导杆上套设有沿其滑动的滑块,各滑块沿高度方向依次铰接,各滑块重心的连线形成一相对于主轴偏心设置的控制轴;直线驱动机构固定端设有绕主轴转动的铰点,活动端与导杆滑块机构中的滑块在控制轴位置处铰接,用于调节控制轴相对于主轴的径向位置;齿轮组机构与直线驱动机构连接,用于调节控制轴相对于主轴的周向位置。本发明可任意改变摆线推进器控制轴的位置,并且精确实现了摆线推进器的运动机理。
