The structural synthesis of screw working organs of the machines mechanisms
Conduction of the synthesis of crew working organs by morphological analysis method in order to gain the construction with improved technical-economy characteristics, also discovering the main characteristics of flexible screw working organs. As a result of conducted analysis of influence of different factors on transportation process and mixing materials by screw working organs by the way of structural scheme synthesis with applying of morphological analysis was determined limited number of their components and relations between them, which represent constructional characteristics. It was investigated, that the choice of the variant of construction of screw working organs will depend on, at first, the character of completion of process and loading. Thus, based on the necessity of ensuring of designing of equally hard spirals, it is possible to limit a number of variants of the constructive solutions and to generate a considerable amount of able to work constructions sections of flexible screw conveyers during transport of friable materials on curved lines drafts. As a result the coding system was designed and synthesis of constructional units of screw working organs with widened technological possibilities, which allows to design and choose competitive constructions of augers, during setting appropriate limitations and using software, which provide qualitative and productive completion technological processes. The investigation of flexible screw working organ was conducted and it were shown the dependence and calculated schemes for determining minimum radius of bend of the conveyor with screw sectional working elements.
