带停歇的齿轮连杆组合机构的设计方法

The Design Method of Gear-linkages Dwelling Combined Mechanism

对于带停歇的齿轮连杆组合机构 ,将与停歇时间Δt对应的曲柄转角Δφ1 和摇杆转角ΔφH 均分为五组对应角度 ,按两连架杆五组对应位置设计曲柄摇杆机构。在求解两连架杆五个位置方程式时 ,采用的方法是先取三个方程推导出有关参数表达式 ,代入另两个方程 ,用限制计算精度的方法求解。用这种方法解非线性方程组的最大优点是 ,不仅求解快捷方便 ,而且求出的结果有三个精确解 ,另两个为满足一定精度的解。

Gear-linkages dwelling combined mechanism together with crank revolution angle Δφ_1 and rocker re-volution angle Δφ_H corresponding with dwell time Δt, is divided equally into five groups of corresponding angles. The crank-rocker mechanism is designed by linking the positions of the five groups. In the process of finding a solution to the equation of linking five positions, the method is used to choose three equations to infer equations with relative parameters, introduce them to the other equations, and solves the equation by using limit precision of calculation. There are two outstanding advantages of using the method-nonlinear equation groups. One is that it is quicker to find solution. The other is that three precise solutions can be obtained and that the other two can satisfy the solution with certain precision.
