The article is dedicated to the synthesis of six-link linkage dwell mechanisms on the basis of straight-line four-bar linkage mechanism. It is shown, that the usage of two-cranked mechanisms instead of crank and balance mechanisms allows to obtain mechanisms with enlarged displacement of the output link, and in case, if that displacement is given - to obtain mechanisms with smaller overall dimensions. For the definition of the geometrical parameters of the mechanisms the methods of the kinematic geometry with the definition of the 5th order straightening points are used. The areas of parameters’ existence of such mechanisms are defined, the appropriate reference diagrams for the synthesis at given values of the dwell of the output link are shown in the article. Theoretical calculations are proved by the results of computer modeling in SolidWorks CAD system.
