Abstract

The invention discloses a turbine bearing case heat insulation flowing channel and an engine with the same, and relates to the technical field of engines. The turbine bearing case heat insulation flowing channel includes a first heat insulation plate, a second heat insulation plate, a third heat insulation plate, and a bearing case; a first installation edge and a second installation edge are axially arranged on the bearing case; one end of the first heat insulation plate is fixedly connected to the first installation edge; one end of the second heat insulation plate is in lap connection with the other end of the first heat insulation plate; one end of the third heat insulation plate is fixedly connected to the other end of the second heat insulation plate, and the other end of the third heat insulation plate is fixedly connected to the second installation edge; and the first heat insulation plate, the second heat insulation plate, the third heat insulation plate and the bearing case form a cooling cavity. The advantages of the invention are that the first heat insulation plate and the second heat insulation plate are in lap connection, the axial heat coordination of the case can be met, cooling of the bearing case is achieved, and the service life of the bearing case can be improved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a heat-insulating runner of a turbine load-bearing casing and an engine having the same. Background technique [0002] The inner ring, outer ring and connecting support plate of the aero-engine turbine load-bearing casing are mostly integrated casting structures, and the load-bearing casing that bears thermal stress and maneuvering load at the same time is one of the weakest structures of the engine. Due to the smoothness of the flow channel, thermal deformation coordination, assemblability and structural size limitations, the connection between the inner ring and outer ring heat insulation runner of the load-bearing casing and the mounting edge of the casing, as well as the inner ring and outer ring heat insulation flow path The connection with the heat shield of the support plate is mostly an overlapping structure, and most of them adopt a circumferential segmented structure, w...
