摘要
根据空间运动刚体速度投影定理和机构的内在联系,经研究给出了主从动面垂直的RSS′R机构主从动件上的等速度点,并给出了主从动件速比的简便求法.以此为基础,讨论了有较广泛应用的两种空间曲柄摇杆机构的极位条件.
Based on introduction for diagrammatizing angle displacement of output bar and pressure angle of mechanism, same velocity point of input and output bar in mechanism is given. The simple method for solving speed ratio of input and output is introduced. Finally, pole position condition for two kind of space crank rocker mechanism which are widely used is discussed.
