Mounting edge connecting structure with air guide function

Abstract

The invention discloses a mounting edge connecting structure with a gas guide function, which is characterized in that the mounting edge connecting structure with the gas guide function comprises a gas turbine bearing seat, a force bearing casing, an elastic support, a gas guide ring and a flow guide plate, and the gas turbine bearing seat, the force bearing casing, the elastic support, the gas guide ring and the flow guide plate are connected through face-to-face mounting edges. Vent holes of the gas turbine bearing seat, the force bearing casing and the elastic support are communicated with a gas guide groove of the gas guide ring to form a cavity, gas flows to the gas guide groove through the vent holes of the gas turbine bearing seat, the force bearing casing and the elastic support, and gas flows to the flow guide plate along the communicated portion of the gas guide groove and the inner diameter of the gas guide ring. The air flow of the guide plate flows to a part needing the air flow along the guide plate vent holes to form a cold air loop channel. The air guide ring has the effects of enhancing heat exchange and reducing the working temperature of parts and the thermal stress of a connecting structure.

Description

technical field [0001] The invention belongs to the technical field of engine air guide structure, and in particular relates to a mounting edge connection structure with air guide function. Background technique [0002] The mounting edges of multiple parts of the aero-engine are usually connected face-to-face, and air guide holes and bolt holes with the same angle are provided on multiple mounting edges to play the role of air guide and fastening. With the continuous improvement of the thrust-to-weight ratio or power-to-weight ratio of aero-engines, it is difficult for the current air-guiding connection structure to guide airflow from multiple installation corners to the same air-guiding hole to multiple locations that require airflow, and it is difficult to adapt to the rapid development of aero-engines. The operating temperature of the aero-engine is getting higher and higher, and the speed is getting faster and faster. In order to improve the heat dissipation efficiency o...
