摘　　要：对等偏距反向转动空间相交轴RCCR机构的位移特性进行了若干理论探讨,得到了两传力杆间圆柱副A的绝对运动轨迹为椭圆,该椭圆所在平面垂直于两回转轴间夹角的角平分线,α角的应小于60°等若干重要结论。Some theoretical about the displacement characteristics of equal-offset and reverse rotation space RC- CR mechanism is discussed. A number of important conclusions is obtained. The absolute motion trajectory of rotation joint A between two transmission rods is an ellipse and the plane containing the ellipse is perpendicular to the bisector of the angle between the two rotary, α angle should be less than 60°, and so on.
