Abstract

Synthesis of a seven-link statically determined spatial hinge mechanism with an additional movable crank link without redundant (passive) connection of the tumbling machine with a complex spatial movement of the working vessel with subsequent analytical study of its design and geometric parameters. Methodology. The analytical method of research is used on the basis of geometric and structural synthesis of a spatial seven-link hinge mechanism with an additional movable crank link without redundant connection of the tumbling machine with a complex spatial movement of the working vessel. The machine was simulated in the SolidWorks-2016 computer-aided design system. Tumbling types of equipment with containers, which perform a different character of movement, are analyzed. On the basis of structural synthesis, the design of a seven-link statically defined spatial mechanism with an additional movable link, a tumbling machine crank, in which the working capacity performs a complex spatial movement, is proposed. Carried out 3D modeling of the machine in the CAD system SolidWorks 2016. Analytical studies of the main geometric parameters of the developed tumbling machine were carried out. Scientific novelty. A relationship has been established between various geometric parameters of the synthesized seven-link statically determined spatial hinge mechanism, in particular, between the center-to-center length of the intermediate connecting rod (working capacity) and the length of the crank, which makes it possible to calculate the necessary ratios of the lengths of the links of the mechanism to ensure the functioning of the machine without jamming its spatial mechanism. Practical significance. A new design of a machine for processing parts has been developed, based on a seven-link statically determined spatial hinge mechanism with an additional movable crank link. Mathematical dependences are obtained for calculating its basic design and geometric parameters. These dependencies can be used in the corresponding design bureaus of machine-building enterprises at the design stage of tumbling equipment with a complex spatial movement of working containers.
