| Abstract: | Clarified the definition of the extreme angleθ,analyzed the possible value range of the crank-rocker mechanism’s extreme angleθas0°,180°).The mathematical expressions of the bar length are derived under the four conditions of zero degree,acute angle,right angle and obtuse angle.The quick-return motions of three types of crank-rocker mechanisms are analyzed,and simulation verification is performed based on ADAMS for the values of the respective extreme angleθand stroke speed ratio coefficient. |
