The paper is dedicated to the kinematic synthesis of dwell linkage mechanisms on the basis of the four-bar linkage. As known, to obtain the dwell of the output link, linkage mechanisms can be used and they have a number of advantages in comparison with other types of mechanisms. Using the kinematic geometry methods, special points of the mechanism’s coupler plane can be found. One of these points is Burmester point and it enables to synthesize four-bar linkages which coupler point traces the curve, a part of which is approximately close to the arc of the circle. By joining the additional structural group, dwell linkage mechanism can be designed. But the problem is to find such parameters of the mechanism which allow designing dwell linkages with a given duration of the dwell. Using the presented numerical and analytical method, this problem was solved; the samples of reference diagrams for the synthesis are also presented in the article. The method enables to carry out kinematic synthesis of dwell mechanisms, taking into account a number of other parameters, such as the length of the links, maximum displacement of the output link, dwell exactitude etc.
