mechanical engineering; turbines and pumps. SUBSTANCE: invention can be used in turbopump sets with several shafts and reduction gear. Proposed turbopump set has turbine and pump whose shafts are connected by reduction gear arranged in housing with inlet and outlet channels. Shafts of turbine and pump are arranged concentrically and form ring space in between which serves as inlet channel Outlet channel communicates with pump inlet. EFFECT: improved efficiency of lubrication and cooling of reduction gear. 1 dwg
