There are several through holes, the pressure ring coordinated with base sealing is provided with above-mentioned pad, above-mentioned brake apparatus is arranged on pressure ring, on
To state base outside wall and be provided with the passage being connected with mounting groove, the axial line of above-mentioned passage is located at the lower section of pressure ring bottom surface,
Above-mentioned passage is connected with external gas source.
As optimization, the top surface of above-mentioned pressure ring is provided with the oblique groove of indent, and the skew wall of the oblique groove is plane, on
Brake apparatus to be stated to be engaged with skew wall, above-mentioned skew wall is α with the horizontal an angle, wherein, 40 °≤α≤50 °.
As optimization, seal groove is offered on the madial wall and lateral wall of above-mentioned pressure ring, is provided with above-mentioned seal groove
Sealing ring, the madial wall or lateral wall of the collar wall protrusion pressure ring of above-mentioned sealing ring, the collar wall of above-mentioned sealing ring and pressure ring
The distance of madial wall or lateral wall is M, wherein, 1.8mm≤M≤2mm.
3rd, beneficial effects of the present invention
The present invention index dial is braked using pneumatic mode, structure is relatively easy, is easy to repair, by axial force with
The collective effect of skew force, to brake apparatus apply pressure with reach to index dial braking effect, its braking effect precision compared with
It is high.
Brief description of the drawings
Fig. 1 is the profile of aerobraking index dial of the present invention；
Fig. 2 is Fig. 1 A portions enlarged drawing；
Fig. 3 is the profile of pressure ring of the present invention；
Fig. 4 is the dimensional structure diagram of base of the present invention.
In figure, 1 is brake apparatus, and 2 be base, and 3 be mounting groove, and 4 be pad, and 5 be pressure ring, and 6 be axial line, and 7 be ventilation
Hole, 8 be sealing ring, and 9 be groove, and 10 be skew wall
Embodiment
Aerobraking index dial of the present invention is described further below in conjunction with the accompanying drawings：
Embodiment one：As shown in Figures 1 to 4, aerobraking index dial of the present invention, include base 2 and be arranged on base 2
Interior brake apparatus 1, wherein, mounting groove 3 is provided with above-mentioned base 2, the pad being bolted is provided with above-mentioned mounting groove 3
Piece 4, the pad 4 are slim pad 4, are evenly equipped with several through holes on above-mentioned pad 4, in the present embodiment, above-mentioned through hole amounts to
Offer 12 and be distributed on annular on pad 4, the pressure ring 5 coordinated with the sealing of base 2 is provided with above-mentioned pad 4, on
State and seal groove is offered on the madial wall and lateral wall of pressure ring 5, sealing ring 8, above-mentioned sealing ring 8 are installed in above-mentioned seal groove
Collar wall protrusion pressure ring 5 madial wall or lateral wall, the collar wall of above-mentioned sealing ring 8 and the madial wall or lateral wall of pressure ring 5
Distance be M, wherein, M=1.95mm；Above-mentioned brake apparatus 1 is arranged on pressure ring 5, and the above-mentioned lateral wall of base 2 is provided with and installed
The passage 7 that groove 3 is connected, the axial line 6 of above-mentioned passage 7 are located at the lower section of the bottom surface of pressure ring 5, be advantageous to pressure ring below 5 and
Space clustering the high pressure gas more than bottom of mounting groove 3, above-mentioned passage 7 are connected with external gas source.
The top surface of above-mentioned pressure ring 5 is provided with the oblique groove 9 of indent, and the skew wall 10 of the oblique groove 9 is plane, above-mentioned system
Dynamic device 1 is engaged with skew wall 10, and above-mentioned skew wall 10 is α with the horizontal an angle, wherein, α=45 °.
Among actual use process, above-mentioned passage 7 will be connected with external gas source, and source of the gas is by high pressure gas from passage
7 are passed into mounting groove 3, and the thickness of above-mentioned slim pad 4 only has 1.2mm or so, and under high pressure, air pressure can pad from being opened in
Through hole on piece 4 enters the bottom of mounting groove 3, causes pad 4 to heave deformation upwards using the recoil strength of air pressure, in pad 4
Pressure ring 5 is promoted to move up during heaving, at the same time, pressure ring 5 is matched somebody with somebody by the inner wall sealing of sealing ring 8 and mounting groove 3
Close, therefore, when air pressure reaches a certain amount of in mounting groove 3, pressure ring 5 can in axial direction be elapsed upwards, due to the groove 9 of pressure ring 5
Skew wall 10 for 45 ° inclination, among the process that pressure ring 5 is passed can it is significantly more efficient driving brake apparatus 1.
