一、蟹爪曲线的计算为了更好地描绘蟹爪尖点的运动规律,首先应求出尖点的运动方程式。由于左右两爪工作机构及其所描绘曲线是以机器的中心线为对称的,故只需对一只蟹爪进行计算就够了。现以左边为例,以曲柄圆盘中心点O为坐标原点,建立直角座标系,用座标法求解蟹爪尖点的运动方程。 1。蟹爪曲线的计算简图曲柄弧(直)形导杆机构,可按图1进行计算,图中符号意义如下:
First, the calculation of crab claw curve In order to better describe the crab claw cusp of the law of motion, we should first find the cusp of the equation of motion. Since the left and right two-jaw working mechanism and its depicted curve are symmetrical about the center line of the machine, it is enough to calculate only one crab claw. Now taking the left as an example, the center of crank disc O as the origin of coordinates, the establishment of Cartesian coordinate system, coordinate method for solving crab claw cusp of the equation of motion. 1. Crab claw curve calculation diagram Crank arc (straight) guide rod mechanism can be calculated according to Figure 1, the symbols in the figure are as follows:
