Oil supply support plate, gas turbine starter and micro gas turbine

Abstract

The invention discloses an oil supply support plate, which is applied to oil supply structures of oil gas turbine starters and micro gas turbines. The oil supply support plate comprises an inner-layerhollow support plate, a pneumatic support plate and a lubricating oil nozzle holder, wherein the inner-layer hollow support plate is connected with an outer oil inlet pipe, and is used for charging lubricating oil; the pneumatic support plate is connected with the inner-layer hollow support plate and is taken as a guider blade; the lubricating oil nozzle holder is connected with the inner-layer hollow support plate, and is used for charging the lubricating oil into a lubricating nozzle of a bearing base; the inner-layer hollow support plate is positioned in the pneumatic support plate; a gapbetween the inner-layer hollow support plate and the pneumatic support plate is uniform. According to the oil supply support plate, a gas turbine starter and a micro gas turbine, a dual-layer supportplate structure is adopted, the gap between the inner-layer hollow support plate and the pneumatic support plate is uniform, and the thickness of each part of the pneumatic support plate is uniform, so that the phenomenon of larger thickness of a certain part is avoided, the maximum thickness of the pneumatic support plate is reduced, the blade loss is reduced, and the vortex efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of an oil supply structure of a gas turbine starter and a turbine part of a micro-combustion engine, in particular, an oil supply support plate, a gas turbine starter and a micro-combustion engine. Background technique [0002] Due to the compact structure of gas turbine starters and micro gas turbines, the guide is often designed as an integrated transition section, that is, the load-bearing support plate and the guide of the transition section are integrated into one casing, and the load-bearing support plate is usually circumferential Evenly distributed multiple aerodynamic blade struts. The blade-type load-bearing support plate (hereinafter referred to as the pneumatic support plate) is used to connect the bearing seat and the guider. The aerodynamic support plate of the turbine part passes through the high-temperature gas passage, and the working temperature is usually above 800°C, and the working condi...
