Abstract
The utility model provides a kind of air intake duct flexible connecting device, for connecting air intake apparatus (1) and gas generator low pressure casing (2), the flexible connecting device includes support ring (3), canvas filler rubber (4) and fastening hoop (5), the canvas filler rubber (4) is V-shaped horn structure, and by being set with fastening hoop (5) at the both ends of V-shaped horn structure both air intake apparatus (1) and gas generator low pressure casing (2) to be connected, and it is used to support the support ring (3) of the canvas filler rubber (4) in the tip concave side setting of V-shaped horn structure.Air intake duct flexible connecting device provided by the utility model, is flexibly connected independent member, can separately maintain, and can be reliably connected to the component of both ends centering inaccuracy.
Description
Technical field
The utility model belongs to combustion engine field of structural design, more particularly to gas generator field, and in particular to a kind of combustion
The flexible connecting device of gas generator and air intake duct.
Background technology
The front end of combustion engine gas generator is low-pressure compressor casing, and air intake duct is the part as equipment, two
Dividing has respective positioning datum, and final combustion engine is reliably assembled together casing and air intake duct two parts when assembly,
To need a kind of installation side type of attachment for having coordination each Self-center-positioning of two components being different from traditional seam allowance.
Air intake duct is the part as gas generator when existing gas turbine test, is mounted on gas generator, installation
While being seam allowance connection, bolt fastening, under the application environment of outfield, air intake duct is part of appliance, and difference is adhered to separately with gas generator
Component has centering adjustment problem.
Utility model content
The purpose of this utility model is to provide a kind of air intake duct flexible connecting devices, overcome or alleviated by the prior art extremely
A few drawbacks described above.
The purpose of this utility model is achieved through the following technical solutions：A kind of air intake duct flexible connecting device, for connecting
Air intake apparatus and gas generator low pressure casing, the flexible connecting device include support ring, canvas filler rubber and fastening hoop, the folder
Cloth rubber is V-shaped horn structure, and by being set with fastening hoop at the both ends of V-shaped horn structure with by air intake apparatus and combustion gas
Both generator low pressure casings are connected, and are used to support the canvas filler rubber in the tip concave side setting of V-shaped horn structure
Support ring.
Preferably, the canvas filler rubber is bellows pattern, and is respectively provided in each tip concave side of bellows
There is the support ring to play a supportive role.
Preferably, it is both provided with the support ring on the inside of two sloped sidewalls in the canvas filler rubber.
A kind of advantageous effect of air intake duct flexible connecting device provided by the utility model is that application flexibility connection fills
It sets, connects gas generator low pressure casing and air intake apparatus, the component of both ends centering inaccuracy can be reliably connected, to
So that gas generator has adjustment axle center and runs the ability that vibration is offset, ensure to be reliably connected, while the flexible connection list
Part is alone become, can be separately maintained.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model air intake duct flexible connecting device.
Reference numeral：
1- air intake apparatus, 2- gas generator low pressure casing, 3- support rings, 4- canvas filler rubbers, 5- fastening hoops.
Specific implementation mode
To keep the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Attached drawing in embodiment, is further described in more detail the technical scheme in the embodiment of the utility model.In the accompanying drawings, from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Described reality
It is the utility model a part of the embodiment to apply example, instead of all the embodiments.Below with reference to the embodiment of attached drawing description
It is exemplary, it is intended to for explaining the utility model, and should not be understood as limiting the present invention.It is new based on this practicality
Embodiment in type, the every other implementation that those of ordinary skill in the art are obtained without creative efforts
Example, shall fall within the protection scope of the present invention.
The air intake duct flexible connecting device of the utility model is described in further details below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of air intake duct flexible connecting device, for connecting air intake apparatus 1 and gas generator low-pressure machine
Casket 2, the flexible connecting device include support ring 3, folder cloth rubber 4 and fastening hoop 5, which is V-shaped horn structure,
Similar roof type structure, and by being set with fastening hoop 5 at the both ends of V-shaped horn structure air intake apparatus 1 and combustion gas occurs
Both device low pressure casings 2 are connected, and are used to support the canvas filler rubber 4 in the tip concave side setting of V-shaped horn structure
Support ring 3.When the gap of air intake apparatus 1 and gas generator low pressure casing 2 between the two is excessive, which can also fit
When use bellows pattern, and the support ring 3 to play a supportive role is both provided in each tip concave side of bellows.No matter
Support ring 3 can be arranged on the inside of its two sloped sidewall by being the canvas filler rubber 4 of V-shaped horn structure or bellows pattern,
To further strengthen support effect.Using the flexible connecting device of the utility model can realize radial and axial flexibility and
Manufacture difficulty can be simplified, reduce manufacturing cost.But in order to reduce this flexible connecting device failure risk, utmostly reduce structure
Bent angle, to preferably select the flexible connecting device of V-shaped wedge angle pattern.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art within the technical scope disclosed by the utility model, the change that can be readily occurred in
Change or replace, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with described
Subject to scope of the claims.
