在设计一台采用四连杆打纬机构的新织机时,需根据引纬、开口等工艺要求定出在前心、纬纱开始引入梭口、后心、纬纱开始引出梭口四个位置的筘座位置与曲轴所对应的角度,并按此来设计打纬机构的四连杆尺寸。本文论述了用运动转置法设计四连杆打纬机构的方法。建立了四连杆打纬机构的坐标方程组;同时又介绍了解该非线性代数方程组的方法,并举一例,以示该理论的具体运用。 When designing a new loom with a four-barbearing beating mechanism, we need to set the front weft according to weft insertion, opening, etc. The weft starts to be introduced into the shed, Siler seat position and the corresponding angle of the crankshaft, and click here to design a four-bar beating mechanism dimensions. This article discusses the method of designing the four-link beating-up mechanism with the sport transposing method. The coordinate system of the four-link beating-up mechanism is established. At the same time, the method of understanding the system of nonlinear algebraic equations is introduced, and an example is given to show the concrete application of the theory.
