按行程速比系数K设计空间曲柄摇杆机构的图解计算法

The gpaphic-and-calculating method for designing spacial crank-rocker mcchanism accoring to trsvel velocity-ratio coefficicnt K

以画法几何和立体几何为理论基础，本文研究探索了按行程速比系数Ｋ（＞１）设计曲柄转轴与摇杆转轴呈垂直交错的空间曲柄摇杆机构的图解计算法，提出了根据机构运动连续性条件确定曲柄固定铰链中心点Ａ的选取原则和选择区域的正确方法。

Take descriptive; geometry and solid geometry;as theoretical basis and according to the coefficient K(> 1) of travelvelocity ratio this paper studied and explored a designing graphic calculation method of the spatial crank-rockep mechanism with perpendicular interlacement between the turning axles of crank and rocker, and accopding to the condition of moving continuity of the mechanism advanced a correct method for determining the choosing principlw and the choosing region' of the central point A of the crank s fixed hinge
