6) double level differential movement
两级差动
1.
This is a triple gear rack mechanism with a triple gear and three racks,which form a double level differential movement mechanism.
本机构采用三联齿轮和三根齿条组成三对齿轮齿条并形成两级差动机构 ,由气缸活塞杆驱动齿条 ,使得三联齿轮的轴心相对于差动齿条运动 ,同时差动齿条相对于固定齿条运动 ,用较小的活塞杆行程通过两极差动获得较大的行程 ,机构占用空间小 ,获得的行程几乎和机构一样大。
