Development of a Heavy-Loaded Hydrodynamic Slide Bearing for a Reducer for a Turbojet Dual Engine

The object of the design is a heavy-loaded hydrodynamic slide bearing for the reducer for a turbojet bypass engine (TJBE) of a new generation for the near-medium-haul main plane (NMHMP) of civil aviation. The aim of the work is to produce working design documentation (WDD) for sliding bearings with anti-friction coatings based on metal polymers, porcelain polymers, composite materials using quasicrystals and developing variants of design and structural schemes for using sliding bearings with anti-friction coatings based on metal polymers, ceramic ceramics or composite materials with using quasicrystals in satellites (gears) of fan reducers of the family are promising TJBE for NMHMP. Designed bearings are designed for use as supports for the intermediate gears of the gearbox, made according to the kinematic scheme "Star". Based on the calculations, the design of the sliding bearing was determined and the WDD was produced for four bearings of the same size with different antifriction coatings used as supports for intermediate gears of the designed TJBE for NMHMP. But, as experience shows, in order to successfully work out the parameters of promising heavily loaded hydrodynamic sliding bearings, a close relationship is needed between the calculated estimate and its experimental verification (while perfecting the tools and methods of both). As a result of this work, WDD was produced for sliding bearings with anti-friction coatings based on metal polymers, ceramic ceramics (silicon carbide, titanium diboride) with and without quasicrystals and composite materials (titanium carbonitride, silicon carbonitride) with and without quasicrystals.
