Zubretskaya Nataliya Anatolievna. The influence of constructive and technological parameters on a durability of spindle junction in a ring-spinning machine. - Manuscript. Dissertation on winning of learned candidate degree of technical sciences on professions 05.02.02 - machine science.- Kiev state university of technologies and design, Kiev, 1999. Dissertation is devoted to settlement of questions, associated with recipiency analytic and experimental dependencies, that allow to provide toughness and exactness of multiple-unit cylindrical spindle joins, formed by combined thermal method, with provision for constructive and technological parameters. The dependencies for computations of technological parameters and tensely-deformed condition of multiple-unit cylindrical joins, formed by combined thermal method were received. The computation method of factual contact area with provision for physicist-mechanical details properties and preparation methods of contact surfaces was offered. Dependence, that allow to define and decrease sense of axial shifts of bushings surfaces was set. The algorithm and software for computation of durability and technological parameters of spindle joins for substantiated choice of their optimum construction attached were developed. Key words: multiple-unit cylindrical joins, spindle, durability, deformation, tensely-deformed state, combined thermal stowage method.
