| Abstract: | According to the classroom practice,this paper concludes the existing condition of whole turn vice and crank with simple and intuitionistic language,and visually analyzes the quick-return characteristics with listing as slider-crank mechanism for example,meanwhile does some parsing and discussions.Mathematical analysis methods are used to solve students’ question.It points out that when the crank is in the upright position the offset slider-crank mechanism achieves the minimum transmission angle.Finally,it summarizes the location of dead point. |
