| Abstract: | Based on the analysis of the link length of a planar five-bar, the assemblability of linkage and the sufficient and necessary condition of the existence of full revolvable joint are proposed. Then, the type of the planar five-bar linkage is analyzed. The existence condition of unconditional triple crank, unconditional double crank, unconditional crank-rocker and double rocker are derived. Based on computer mechanism simulation, the coupler curve of a hybrid five-bar linkage with double crank are investigated and some laws of coupler curve are derived for the first time. |
