摘　　要：针对等偏距同转向空间相交轴RCCR的位移特性展开了理论分析,得到了两传力杆间圆柱副A的绝对运动轨迹为椭圆,反映两回转轴夹角大小的α角应在-60°<α<90°范围内取值等若干重要结论。The displacement characteristics of the equal - offset and same - direction rotation space RCCR mechanism is theoretically analyzed. Several important conclusions are obtained. Here are two of them, one is that the absolute motion trajectory of the column auxiliary between two dowel steels is ellipse and the other is that the angle a between two axes should be ranged from - 60° to 90°.

关 键 词：位移 等偏距 同转向 椭圆轨迹最小杆长
