Description
Technical field
The present invention relates to a kind of gas oil separation structures.
Background technology
Because of the rotation of the components such as bearing, gear and oil lubrication splash when aero-engine works, cause to exist in bearing bore
A large amount of mist of oils blend to form oil gas with bearing chamber air, and oil gas is unfavorable for lubrication and the cooling of system, it is therefore desirable to by oil gas
Discharge.If the oil gas in bearing bore, which is expelled directly out, will cause a large amount of consumption of lubricating oil, and pollute environment, therefore must will be in bearing bore
The lubricating oil contained in air is separated, to reduce lube use rate.Generally use centrifuge formula ventilator realizes oil gas at present
Separation, centrifuge formula ventilator are that the separation of liquid phase oil droplet in oil gas is carried out using centrifugal principle.Structure is mainly by rotor, shell
And the compositions such as bearing support, it is a complete attachment, is driven by special transmission mechanism.Rotor is to realize Oil-gas Separation
Core carries the impeller of 6~8 disc, and center is the central shaft of supporting rotor, and venthole is typically recessed on axis.It is mingled with sliding
After the oil gas of the small oil droplet of oil enters centrifuge formula ventilator, wheel rotation keeps air outwardly radial by one with the small oil droplet of lubricating oil
Power, i.e. centrifugal force.Since lubricating oil is different from the density of air, lubricating oil is thrown to inner walls by centrifugal force, by wall
Aperture flows back to casing inner cavity or bearing bore, and the gas after being detached is discharged from centre bore, to realize the function of Oil-gas Separation.It is existing
Some gas oil separation structures is complicated, need to design special transmission mechanism to drive, and the power of consumption of engine carries out when work
Oil-gas Separation reduces the output power of engine.
Invention content
The object of the present invention is to provide a kind of gas oil separation structures, while realizing Oil-gas Separation, need not be special
Transmission mechanism drives, simple in structure, and reduces the power consumption of engine.
The technical scheme is that the gas oil separation structure includes engine spindle, oil gas guide sleeve, mobilize owner
Axis is hollow-core construction, is formed by connecting by compressorshaft and turbine wheel shaft, is passed through equipped with radial on the compressorshaft positioned at fore bearing chamber
The oil gas guide sleeve of main shaft is worn, oil gas guide sleeve is being provided with venthole positioned at main-shaft core position, and turbine wheel shaft is radially provided with 2 uniformly
The first oil circuit hole, turbine wheel shaft be additionally provided on the inner wall near exhaust pipe internal diameter be more than inner wall surface annular oil-collecting
Slot, and the second oil circuit hole is provided on oil trap, the first oil circuit hole is mutually in 90 ° along engine spindle axis with the second oil circuit hole
The hollow-core construction at angle, the engine spindle extends to exhaust pipe.
In the use of the present invention, since fore bearing is to use pressure seal, the air pressure in bearing bore is more than ambient pressure, because
The oil gas in bearing bore enters compressor spindle axis under the action of bearing bore chamber pressure by oil gas guide sleeve before this.Into
The oil gas of spindle axis is rotated with main axis, and enters the turbine wheel shaft axle center being connected with compressor main shaft.Oil gas is rotating
Oil-gas Separation is carried out due to centrifugal force in the process, small lubricating oil oil droplet hits the condensed on inner walls in spindle axis into oil droplet.Oil
After pearl is expelled directly out from the first oil circuit hole or is collected on oil trap, it is discharged by the second oil circuit hole, the lubricating oil of discharge can be again
It utilizes, and the air separated is discharged into air after entering exhaust section burn-up by exhaust pipe along turbine wheel shaft.The present invention is using now
The high-speed rotating engine spindle structure having, does not need individual separating mechanism, while realizing Oil-gas Separation, not only may be used
To subtract low power consumption, the air of separation is burnt up through exhaust section, reduces the pollution to extraneous atmospheric environment.
