This article discusses the synthesis of a six-link transforming mechanism of a rocking machine.First, the problem of synthesizing a four-link articulated-lever mechanism for reproducing a verticalline was solved. For this purpose, the problem of synthesizing a rectilinear-guiding mechanism ofthe Evans type, which is a hinged-lever four-link mechanism with a straight vertical line drawingpoint, is considered. The task of synthesis is to implement the constraint equation. The geometricmeaning of the constraint equation is to determine the hinge, the positions of which in the absolutecoordinate system are equidistant from the origin of the OXY coordinate system.The problem of synthesis is formulated as a problem of quadratic approximation. According to thefound dimensions of the articulated four-link, performing the position analysis, the true positionsof the suspension point of the rod column were determined. After that, the found parameterswere refined using the output criterion directly, that is, the deviation from the given rectilineartrajectory.After the synthesis of a straight-line guiding mechanism, a drive kinematic chain was synthesized,which consists of a crank and a connecting rod.Thus, a rocking machine drive mechanism was obtained, containing a base, a crank pair connectedto the main hinged four-link mechanism. The technical result is achieved by the fact that a two-linkgroup is attached to the main four-link mechanism, forming a class III mechanism. The attachedtwo-drive group is the leading crank connected to the rack and connecting rod.Based on the obtained dimensions of the six-link converting mechanism, an experimental modelwas developed, which fully confirmed the efficiency of the transforming mechanism.DOI

Практическое значение
The practical significance of this study lies in the synthesis and experimental validation of a six-link transforming mechanism for the drive of a rocking machine. As a result of the research, the parameters of a four-link articulated-lever mechanism capable of providing motion close to a vertical straight-line trajectory were determined. By adding a two-link driving group consisting of a crank and a connecting rod, a class III six-link mechanism was developed. The proposed mechanism can be used in the design and improvement of rocking machine drives, particularly in oil production equipment. It makes it possible to improve the kinematic characteristics of the drive by ensuring that the suspension point of the rod column moves along a trajectory close to the required straight vertical line. This may contribute to increased operational reliability, reduced energy losses, and an extended service life of the equipment. The experimental model developed on the basis of the obtained dimensions confirmed the efficiency and operability of the transforming mechanism. Therefore, the results of this study can be applied in the development of new rocking machine drive mechanisms, the modernization of existing machines, and the design of straight-line guiding mechanisms in mechanical engineering.Данный документ располагается в коллекциях
