Структурне дослідження механізмів третього та четвертого класів

Abstract

The purpose of this work is to study structural mechanisms of the third and fourth classes of different variants, which consist of structural groups with four units and six kinematic pairs. We have obtained structural formulas of complex flat mechanisms, taking into account the properties of structural schemes to change the class of mechanism depending on the selected other possible input link of the mechanism. We have made a structural analysis of the complex flat mechanisms of the third and fourth classes on the basis of possible variants of the struc-tural groups of the third class of the third order and the fourth class of the second order. The obtained structural formulas allow to simplify further kinematic and power force studies of such mechanisms and to increase their accuracy.
