摘要
有急回作用的四杆机构是应用较广的四杆机构之一。笔者就其传动角提出了新的评价标准,并借助于计算机求得具有最佳传动角的平面急回四杆机构,为设计者提供了新的有效的设计方法。
The quick-return qudric-crank machanism is a mechamism widely applied. A new performance index for qudric-crank mechanism transmission is presented,and a method for computer-aided design of quick-retrrn quadric-crank mechanism is given in this paper.
