TURBINE ROTOR AXIAL SECTION

摘要

FIELD: engines and pumps.;SUBSTANCE: turbine rotor axial section comprises outer peripheral surface adjoining two face first lateral surface and additional peripheral surface, adjacent to one of the first lateral surfaces. Said outer peripheral surface has at least one slot for turbine working vane. Said additional peripheral surface has at least one sealing slot, open radially outward, with several sealing elements fitted therein. Said sealing elements overlap at least partially, face openings of slots holding working vanes. There is a hole in second lateral surface for every sealing element that passes axially to penetrate through at least one of sealing element lateral wall. Every sealing element is clamped against displacement towards periphery by pin fitted in hole. There is also a gadget to prevent pin from displacing along said hole, which comprises safety plate. The latter has at least one hole aligned with that in sealing element lateral wall for pin fitted in aligned holes to lock safety plate.;EFFECT: simple mounting and dismantling of sealing elements.;14 cl, 16 dwg
