Abstract

The invention provides an axial ventilator, which comprises a ventilator rotor, a first honeycomb separator, a second honeycomb separator, a ventilator support and a ventilator cover; the first honeycomb separator and the second honeycomb The body separators are arranged side by side on the ventilator rotor, and the ventilator support body is arranged between the first honeycomb body separator and the second honeycomb body separator, separating the first honeycomb body separator and the second honeycomb body separator Open, and extend upward along the upper end of the first honeycomb separator to form a connecting portion; the ventilator cover is arranged above the first honeycomb separator and the second honeycomb separator to prevent debris from entering the bearing cavity . The axial ventilator of the present invention can make the axial ventilator have higher service life and oil-gas separation efficiency than common honeycomb structure ventilators. At the same time, it has higher structural strength and reliability, increases the length of the oil-gas mixture flow channel, and improves the oil-gas separation efficiency.

Description

technical field [0001] The invention relates to the field of gas turbine engines, in particular to an axial ventilator. Background technique [0002] A gas turbine engine generally mainly includes a compressor, a combustor, and a high-pressure turbine. Among them, the compressor is mainly used to compress the air and make it enter the core engine, the combustor is mainly used to mix the compressed air and fuel and burn it fully to generate high-energy gas flow, and the high-pressure turbine is mainly used to inject gas from the combustor. Extract energy from the high energy gas flow to drive the compressor. In an aviation turbofan engine, the low-pressure turbine located downstream of the core engine extracts energy from the high-energy gas flow ejected from the combustion chamber and drives the fan, which provides the main thrust generated by the engine. [0003] The rotor is usually fixed by multiple fulcrum bearings in the engine. Generally, for a dual-rotor engine, fu...
