After refer to the axis of trunnions that Fig. 1 and Fig. 2, Fig. 1 provide and reel cage anti-radial impact device for the embodiment of the present invention
TV structure schematic diagram；The axis of trunnions that Fig. 2 provides for the embodiment of the present invention and the forward sight structural representation of reel cage anti-radial impact device
Figure.
The axis of trunnions that the embodiment of the present invention provides and reel cage anti-radial impact device, including the axis of trunnions and reel cage 1, reel cage 1
Including supporting seat the 2, first support 3 and the second support 4, the first support 3 and the second support 4 are disposed on support seat 2, trunnion
Axle includes the first axle body 5 and the second axle body 6, and is arranged between the first support 3 and the second support 4, and the first support 3 offers
First through hole, one end of the first axle body 5 is built in the first through hole and is connected by the first bush bearing and the first support 3
Connecing, the second support 4 offers the second through hole, one end of the second axle body 6 is built in the second through hole and by the second monoblock type
Sliding bearing and the second support 4 connect.The axis of trunnions that the present invention provides uses at two supports with reel cage anti-radial impact device
While two bush bearings of upper balanced configuration realize ensureing that back seat can rotate, improve radial load and bear energy
Power, wherein, the rotating function of the architecture circular motion of bush bearing itself, it is ensured that back seat 8 can rotate, adapt to
The angle of pitch requirement of reel cage 1 relative transmission pipe 7, meanwhile, utilizes the structure of balanced configuration, and bush bearing is beneficial to
Carrying the biggest load, the feature of large impact, improve radial load ability to bear, back seat kinetic energy when bearing and transmit multitube salvo
To support and the impact that supports seat, and the most deliberately pursue manual lightness and motility and " unnecessary rotation is light and handy
Property ", it is beneficial to solve the radial impact strength problem that " bearing-type rotating shaft " brings, improves reliability, economy, structure the most more letter
Single.
The primarily radial load of stress of the junction of the axis of trunnions and reel cage 1, " ball bearing " and " roller bearing " though
Also it is to bear radial load be main, but the radial load that " ball bearing " and " roller bearing " can bear is than monoblock type cunning
Dynamic bearing is much smaller, and, the functional contact face Area comparison of bush bearing is big, and its " than pressure value " is than above-mentioned bearing
Greatly, and width range can be with requiring non-standard de-sign.
Wherein, the first bush bearing is metal material, and the second bush bearing is metal material, uses effect
Fruit is more preferably.
Wherein, the first bush bearing is provided with lubricating arrangement, the second bush bearing is provided with profit
Sliding device, convenient lubrication.
The embodiment of the present invention also provides for a kind of discharger, including transmitting tube 7, back seat 8, the axis of trunnions and reel cage 1, transmitting tube
7 are arranged on back seat 8, and reel cage 1 includes supporting seat the 2, first support 3 and the second support 4, and the first support 3 and the second support 4 are spaced
Being arranged on the side supporting seat 2, back seat 7 is fixed on the opposite side supporting seat 2, and the axis of trunnions includes the first axle body 5 and the second axle body
6, and be arranged between the first support 3 and the second support 4, the first support 3 offers the first through hole, one end of the first axle body 5
It is built in the first through hole and is connected by the first bush bearing and the first support 3, the second support 4 offers second
Through hole, one end of the second axle body 6 is built in the second through hole and is connected by the second bush bearing and the second support 4,
While being capable of ensureing that back seat 8 can rotate, improve radial load ability to bear.
In order to optimize such scheme further, back seat 8 is an entirety, and back seat 8 is provided with multiple transmitting tube fixed bit
Putting, transmitting tube 7 is arranged on transmitting tube fixed position.It is, multiple transmitting tubes 7 are to share same back seat 8, it is thus possible to
Enough multiple transmitting tubes 7 are treated as an entirety, form all-in-one-piece " rear seat assembly " so that the transmitting tube 7 of scattered distribution
" disequilibrium " problem during transmitting obtains relatively good solution, and, the size of monoblock type back seat is relatively big, but weight is basic
Being same as the summation of each dispersal unit, the back seat kinetic energy produced when its part transmitting tube 7 therein is launched, meeting peptizaiton is in back seat
Each position of assembly, the back seat kinetic energy making the big quality of rear seat assembly produce to undertake part transmitting tube to launch, make rear seat assembly
Back seat speed be far smaller than single tube, independence, dispersion launch time speed, reduce the pressure of antibacklass mechanism, thus ensure
Launching effect.Further, owing to have employed the axis of trunnions and the reel cage anti-radial impact device that the embodiment of the present invention provides, it is possible to bear
Bigger radial impact, when bearing and transmit multitube salvo, back seat kinetic energy is to support and the impact of support seat, therefore, uses entirety
" the rear seat assembly " of formula is entirely without problem.Wherein, transmitting tube 7 is in matrix arrangement so that counteracting force is more uniform, more
Be conducive to eliminating.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple amendment to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein and features of novelty phase one
The widest scope caused.
