Abstract

The work purpose: the choice of promising design-technological ways to support high indices of wear-resistance and friction costs decrease with regard to conditions of parts operation in swivels. The research methods: the set of tribotechnical researches on wear-resistance, on friction loss and physical and chemical parameters. The novelty: there are offered fundamentals for development of new designs of sliding bearings with increased wear-resistance at the expense of the favorable stressed state formation in functional layers, and also thermal physical and damping indices. Investigation results: support of increased thermal conductivity and thermal capacity increase of the materials under consideration gives possibility to increase considerably the friction unit efficiency in swivels, and also at the expense of thermal power accumulation with structural constituents of materials. Wear-resistance increase in the friction unit is provided with the formation of residual compression stresses in a functional surface layer, and the presence of an expanded spring in the bearing system contributes to the increase of its damping characteristics. Conclusions: the design and technological methods offered for working capacity increase and life increase of swivel parts allow assuring increased mechanical and tribological characteristics to a considerable extent and optimizing thermal modes.
