Abstract Theoretically proved that the displacement of the center of mass of a mechanical system for any of the corners of the counter rotational movement of its working bodies in the plane of the reference body independent of the resistance movement of the environment and supporting the body always remains constant such that for an infinite resistance. Infinitesimally small and the zero resistance to displacement of the center of mass becomes impossible. This effect led to develop Savelkaev inertsioid.
Keywords

Abstract Structures for power trains (transmissions) with three degrees of freedom as a full set of vertexedge incidence matrixes are presented. General rules for making the incidence matrixes to avoid the isomorphic transmission structures are formulated. Generalized structures and structural diagrams as well as bases of a velocities plan are entered and used for an analysis of transmission properties. The rational kinematic schemes which combined the simple and planetary gear trains are suggested.
Keywords
