Coaxial contra-rotating circumferential propeller
Coaxial contra-rotating circumferential propeller
A coaxial contra-rotating circumferential propeller, comprises an input end (1), a one-way commutator, a two-way deflector, a steering support, and two output ends (13, 14). The input end is connectedto a power device. The one-way commutator converts one rotation into two rotations having the same rotation speed and opposite rotation directions. The two-way deflector is respectively indirectly connected to two shafts and two output shafts of a contra-rotating sleeve shaft by means of two bevel gear pairs (5-8). Two one-way deflecting torques respectively generated by the two bevel gear pairshave the same direction and opposite directions. By transferring by means of a bracket or an output sleeve shaft (12), the two one-way deflecting torques cancel each other. The two output ends are respectively connected to two propellers (or rotors). A turnover control device controls the turnover of the steering support, the control torque required for co-rotating and contra-rotating is the same,the turnover control torque is small, and the control device is small.
一种共轴反转周向推进器，包括输入端(1)、单路换向器、双路折向器、转向支座、两个输出端(13、14)。输入端连接动力装置。单路换向器把一个转动转化为转速相等、方向相反的两个转动。双路折向器通过两副锥齿轮副(5‑8)分别间接连接反转套简轴的两个轴与两个输出轴，两副锥齿轮副分别产生的两个单向偏转力矩大小相同、方向相反；通过支架传递或通过输出套简轴(12)传递，两个单向偏转力矩相互抵消。两个输出端分别连接两个螺旋桨(或旋翼)。周转控制装置控制转向支座周转，正转与反转所需的控制力矩相同，周转控制力矩小，控制装置小。
