Abstract
The present invention is a kind of pressure hull structure of bellows accumulator, belongs to actuator design field.It is characterized by: the present invention includes connecting flange, front end end cap, rear end end cap and middle casing, front end end cap is " convex " font structure, rear end end cap is the hemispherical dome structure of indent, connecting flange and front end end cap are welded on one, connecting flange welds together with middle casing, middle casing welds together with rear end end cap, forms the pressure hull structure of bellows-type accumulator.
Description
Technical field
A kind of pressure hull structure of bellows accumulator, belongs to actuator field.Present invention could apply to electricity quiet nights
(EHA) actuator product.
Background technique
Electric hydrostatic actuator (EHA) is as next-generation electric aircraft standard configuration, since EHA actuator is an independent work
Make component, in temperature change, the volume of actuator internal work medium can change, need accumulator in real time accommodate or
Working media is supplemented, when working media is revealed, it is also desirable to which accumulator supplements working media, accumulator master used at present
If spring accumul ator.
New type corrugated tubular type accumulator, bellows accommodate the volume of working media variation, while compressed gas by stretch/shrink
Body adjusts the pressure of working media by compression/expansion, can reduce the structure size of accumulator, the working media of accumulator
In a seal cavity, stationary seal structure can reduce the possibility of working media leakage, simple and compact for structure, can
By property height, comprehensive performance is due to spring accumul ator structure.
Summary of the invention
The purpose of the present invention is: propose a kind of pressure hull structure of bellows accumulator.
The technical scheme is that
A kind of pressure hull structure of bellows accumulator, including front end end cap 1, connecting flange 2, middle casing 3 and after
Hold end cap 4；It is characterized by: wherein, front end end cap 1 is " convex " font structure, and protrusion is towards pressure hull inside cavity；
Rear end end cap 4 is inner concave shape semiglobe, is protruded to case inside.
The connecting flange 2 and front end end cap 1 and middle casing 3 pass through welded connecting.
The middle casing 3 and rear end end cap 4 passes through welded connecting.
The middle casing 3 and rear end end cap 4 component processing as a whole.
The connecting flange 2, middle casing 3 and rear end end cap 4 can be used as a global facility and process.
The invention has the advantages that
1) front end end cap is " convex " font structure, and the ring-groove-type space formed between front end end cap and middle casing is for holding
It receives complete compressed bellows, the structure size of bellows-type accumulator can be effectively reduced；
2) rear end end cap is the hemispherical of indent, can reduce the thickness of rear end end cap in the case where bearing same pressure
Degree, and then reduce the weight of bellows accumulator.
Detailed description of the invention
Fig. 1 is bellows-type accumulator pressure hull structure sectional view of the present invention；
1 front end end cap, 2 connecting flange, 3 middle casing, 4 rear end end cap
Specific embodiment
The present invention is described in further details below with reference to Fig. 1.
A kind of pressure hull structure of bellows accumulator of the embodiment of the present invention, feature include front end end cap 1, connection
Flange 2, middle casing 3 and rear end end cap 4；
Connecting flange 2 and front end end cap 1 pass through welded connecting；
Connecting flange 2 and middle casing 3 pass through welded connecting；
Middle casing 3 and rear end end cap 4 pass through welded connecting；
Front end end cap 1 is " convex " font structure, and protrusion is towards pressure hull inside cavity；Rear end end cap 4 is indent
Type semiglobe is protruded to case inside；In above structure, middle casing 3 and rear end end cap 4 can be used as a global facility
Processing.In above structure, connecting flange 2, middle casing 3 and rear end end cap 4 can be used as a global facility and process.
