Title in English

OPTIMIZATION OF CIRCULATION OF FLOOR ABRASIVE WORKING ENVIRONMENT IN VIBRATION-CENTRIFUGAL INSTALLATIONS

English abstract

In this work, the introduction of vibration processing with free loading of parts into a loose abrasive medium, which has a wide variety of physical and mechanical characteristics, into the technological process of finishing was substantiated. It was established that the productivity and quality of the vibration processing process determines the nature of the circulation movement of the bulk working medium and the parts being processed. One of the main factors that shape this process is vibration modes, designs of working chambers, volume and degree of their filling. The analysis of the parameters of the circulation movement of the working environment made it possible to create several dynamic groups of vibration processing units, which allow the intensification of processing processes while reducing the dynamic tension of their elements, reducing the complexity of kinematic schemes. An overview and analysis of the existing vibration- centrifugal installations were carried out. The analysis of the vibration-centrifugal processing processes is based on the nature of the interaction of the abrasive granule with the surface of the part with the three-dimensional angular vibration of the working chamber. The diversity of the circulation of loose abrasive media in vibrationcentrifugal installations has been revealed. To expand the possibilities of vibration-centrifugal processing, new devices are created, in which, in addition to changing kinematic schemes, it is possible to improve their working chambers. Thus, in vibration-centrifugal installations, instead of a conical or spherical working chamber, a chamber with faceted elements of the side surface can be used. The creation of faceted side surfaces of working chambers will allow diversifying the circulation of the abrasive working medium, its speed and energy intensity, which will create new possibilities and varieties of the technological process of vibration-centrifugal processing of parts. Ways of creating new vibration-centrifugal installations for increasing the intensity of circulation of the working environment are proposed, which determines the productivity and reliability of vibration-centrifugal installations.
