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.
