Abstract

The article shows the possibility of developing the method of structural synthesis of flat closed kinematic chains by M. Grubler, into closed kinematic chains of moving links of all families and spaces. The universal structural system of Professor L. T. Dvornikov for closed kinematic chains of moving links of all families and spaces is given. A complete set of solutions has been found describing the organization of closed kinematic chains of movable links of the second, third and fourth subfamilies of the first family with the complexity of the basic chain link equal to two and three, the mobility of the chain equal to six and the total number of chain links from three to six. Combinations of kinematic pairs and links have been obtained, which make it possible to find all, without exception, structural schemes closed kinematic chains of movable links of the first family under given parameters, from which, by stopping a link connected to an adjacent link of the chain by a kinematic pair of the fifth class, single-moving assur mechanisms can be formed.
