Description
Technical field
The present invention relates to a kind of connection structures of big opening solid propellant rocket, are suitable for rocket engine.
Background technique
Burning chamber shell is solid propellant rocket important component, provides charge space for engine, takes engine work
Make load and guided missile external applied load, needs compact, lightweight, reliable connection type.Current combustion room housing and end socket connection type
Mainly there are bolt, screw, screw thread, pin, snap ring, retaining ring, wherein snap ring connection has the advantages that passive quality is small, middle-size and small-size
Solid propellant rocket is widely applied.However, the connection of monoblock type snap ring needs to reduce connection structure in connection structure uplifting window
Reliability；Monoblock type snap ring installation space is big simultaneously, increases engine passiveness quality；And its requirement on machining accuracy is high, peace
Dress needs special tooling, and disassembly is difficult.
Summary of the invention
In order to solve the deficiencies in the prior art, the present invention provides a kind of wedge-shaped piecemeal check ring joint structure, machining accuracy is low,
Installation and removal are convenient, sealing effect is good, connection reliability is high.Meanwhile connection structure is compact, it is possible to increase free loading propellant engine
Explosive payload improves engine and always rushes.
The present invention is directed to the connection method of big opening burning chamber shell and end socket, devises a kind of height of wedge-shaped piecemeal snap ring
It is reliably connected mode.The connection type can realize the reliable and secure connection of burning chamber shell and end socket, guarantee axial between the two
Positioning and circumferential positioning function.High combustion chamber pressures by force with external applied load under the conditions of, snap ring stress meet material working strength requirement,
Excessive deformation does not occur, extrusion stress and shear stress guarantee that snap ring does not fall off and destroys within allowable stress range.
Wedge shape piecemeal check ring joint structure provided by the invention, including burning chamber shell, slotted countersunk flat head screw, fixed block,
Sealing ring, is first put into the seal groove of end socket by fixture block, sealing ring, end socket, and end socket is packed into burning chamber shell, is connected with fixture block
(burning chamber shell has a card slot for installing fixture block in circumferencial direction), by the boss axial limiting of burning chamber shell；Fixture block
It is fixed by fixed block, is screwed into slotted countersunk flat head screw fastening in the annular slot of combustion chamber shell body sidewall.
Further, fixture block material is unimach, is made of the wedge-shaped fixture block of 6 yin and the wedge-shaped fixture block of 6 sun, realizes combustion
Room housing is burnt to connect with end socket；6 wedge-shaped fixture blocks of yin are fixed with the wedge-shaped fixture blocks of 6 sun by 12 pieces of fixed blocks, the wedge-shaped fixture block of yin or
Positive wedge shape fixture block is aligned by negative wedge-shaped fixture block groove or the wedge-shaped fixture block groove of sun with fixed block cooperation, guarantees the wedge-shaped fixture block of yin or positive wedge
Shape fixture block carries out circumferential limit.Axial gap has been reserved between fixture block and fixed block, is conducive to fixture block deformation, is prevented fixed block
It is squeezed by fixture block.
The invention has the advantages that
(1) compact-sized, motor charge amount is increased, motor mass fraction is improved, engine is increased and always rushes.
(2) installation and removal are convenient, and craftsmanship is high.
(3) small, bearing capacity height is deformed, suitable for the connection of High Voltage engine.
Detailed description of the invention

Fig. 2 is the wedge-shaped fixture block right view of present invention yin and the wedge-shaped fixture block right view of sun；
In figure, 1- burning chamber shell, 2- slotted countersunk flat head screw, 3- fixed block, 4- fixture block, 5- sealing ring, 6- end socket, 7- are convex
Platform, the wedge-shaped fixture block groove of 8- yin, the wedge-shaped fixture block groove of 9- sun, the wedge-shaped fixture block of 10- yin, the wedge-shaped fixture block of 11- sun.
Specific embodiment
Below by specific embodiment the present invention will be further explained explanation.
The present invention can realize in many different forms, and should not be construed as being limited by the example herein proposed.On the contrary,
It proposes these embodiments and is to reach sufficiently and complete disclosure, and those skilled in the art is made to understand this hair completely
Bright range.
Big opening burning chamber shell and end socket connection structure is described in detail in Fig. 1, using radial seal structure.The present embodiment
It mainly include burning chamber shell 1, slotted countersunk flat head screw 2, fixed block 3, fixture block 4, sealing ring 5, end socket 6.It is sent out according to solid-rocket
The charge constitution form of motivation free loading propellant uses wedge-shaped piecemeal fixture block connection type.Sealing ring 5 is first put into end socket 6
In seal groove, end socket 6 is packed into band burning chamber shell 1, by 7 axial limiting of boss of burning chamber shell 1.Burning chamber shell 1 and envelope
First 6 are connected using fixture block 4.The fixture block 4 is by the wedge-shaped fixture block 10 (see Fig. 2) of 6 yin and wedge-shaped fixture block 11 (see Fig. 2) group of 6 sun
At material is unimach.There is an annular slot in 1 side wall of burning chamber shell, is first put into the wedge-shaped fixture block 11 of a piece of sun
1 annular slot of burning chamber shell prevents sun to Zhunyang wedge-shaped card block slot 9 with the wedge-shaped fixture block 11 of fixed block 3 (see Fig. 2) fixed sun
Wedge-shaped fixture block 11 rotates, and is screwed into slotted countersunk flat head screw 2, and burning chamber shell 1 is connect with fixed block 3.Then by a piece of negative wedge
Shape fixture block 10 is put into 1 annular slot of burning chamber shell, with the wedge-shaped fixture block 10 of the fixed yin of fixed block 3, to Zhunyin wedge-shaped card block slot 8,
Tighten slotted countersunk flat head screw 2.Positive wedge shape fixture block 11 and the wedge-shaped fixture block 10 of yin, are sequentially placed into 1 annular slot of burning chamber shell, until
It completes burning chamber shell 1 and end socket 6 is installed.
The disassembly process of burning chamber shell 1 and end socket 6 first backs out the corresponding fluting countersunk head of any a piece of wedge-shaped fixture block 10 of yin
Screw 2 removes fixed block 3, takes out the wedge-shaped fixture block 10 of yin；Similarly, the wedge-shaped fixture block 11 of a piece of sun is further taken out.Successively take out yin wedge shape
Fixture block 10 and the wedge-shaped fixture block 11 of sun, until completing disassembly.
The present invention is sealed in carrying out use process using O-ring seal 5；Step 7 guarantees burning chamber shell 1 and end socket 3
Axially position；Negative wedge shape fixture block groove 8 or positive wedge-shaped fixture block groove 9 guarantee fixture block 4 and the circumferential positioning of fixed block 3；In fixed block 3 and card
Axial gap has been reserved between block 4, has prevented fixed block 3 to be squeezed and deformed by fixture block 4 and destroys.
The present invention gives a kind of wedge-shaped piecemeal check ring joint structures, and installation and removal are convenient, compact-sized, sealing effect
Good, bearing capacity is high, ensure that burning chamber shell 1 is connect reliably and work safety with end socket 6.
