Abstract
The invention belongs to field of airplane structure, and in particular to a kind of draw off gear for door ladder Integral type hatch door.A terraced Integral type cabin door structure is generallyd use on Modern Small passenger plane, helicopter at present, existing door ladder Integral type hatch door draw off gear has hydraulic draw off gear, electrical actuation draw off gear and gas spring auxiliary draw off gear.In order to adapt to modern aircraft design theory, the draw off gear of door ladder Integral type hatch door of the present invention uses steel wire rope component, and the cable disk component (4) of steel wire rope component (2) has buffer structure by being driven after gear set.Without the energy on machine, maintenance operation cost is low, easy to operate simple, performance stabilization, high reliablity, the advantages that pollution-free, noiseless, structure is simple, the service life is long, cheap, comply fully with the design concept of modern aircraft, it will be a first choice for terraced Integral type hatch door draw off gear, be worth with very big Economic Application.
Description
Technical field
The invention belongs to field of airplane structure, and in particular to a kind of draw off gear for door ladder Integral type hatch door.
Background technique
A terraced Integral type cabin door structure, existing door ladder Integral type are generallyd use on Modern Small passenger plane, helicopter at present
Hatch door draw off gear has hydraulic draw off gear, electrical actuation draw off gear and gas spring auxiliary draw off gear.
Hydraulic draw off gear provides hydraulic energy by airplane hydraulic pressure source and drives acting device either on or off hatch door, hydraulic actuation
The phenomenon that decline of pressure that will appear hydraulic actuator is parked for a long time in aircraft outfield, causes landing gate freely to fall completely when serious
Body causes landing gate rotation and jack damage.
Electric draw off gear provides electrical energy drive acting device either on or off hatch door, system complex failure rate by aircraft power supply
It is high.
Gas spring assists draw off gear to open and close hatch door by gas spring spring performance assist operators, by temperature
It influences greatly, the service life is short.
Summary of the invention
In order to adapt to modern aircraft design theory, the present invention provides the energy on a kind of saving machine, reduces maintenance operation cost
Door ladder Integral type hatch door draw off gear.
One end of a kind of draw off gear for door ladder Integral type hatch door, hatch door and steel wire rope component connects, wirerope group
The other end of part is fixed and is wrapped on cable disk component, and the first gear of fixed transmission shaft and gear pair is same with the cable disk component
The planetary gear of axis connection, first gear and planetary reduction gear connects, and the breast wheel of planetary reduction gear is connect with driving device；It is described
The second gear of gear pair is connect with torsion-bar spring component, which is connect by pivoted arm with buffer.
Pulley assembly is also equipped between the steel wire rope component and cable disk component.
The breast wheel of the planetary reduction gear is connect by bevel-type reversing gear with driving device.
The driving device is Handleset.
The rotary shaft of the second gear is connect by spline with the movable end of torsion-bar spring component, and torsion-bar spring component is another
One end is fixed.
Buffer is hydraulic one-way damper buffer, and the other end is connect with body.
The utility model has the advantages that without the energy, maintenance operation cost on machine low, easy to operate simple, performance stabilization, high reliablity,
Pollution-free, noiseless, the advantages that structure is simple, the service life is long, cheap, the design concept of modern aircraft is complied fully with, will be
The first choice of the terraced Integral type hatch door draw off gear of door, is worth with very big Economic Application.
Detailed description of the invention
Fig. 1 is the schematic diagram that the present invention is used for door ladder Integral type hatch door draw off gear.
1. hatch door, 2. steel wire rope components, 3. pulley assemblies, 4 cable disk components, 5. gear pairs, 6. torsion-bar spring components, 7. turns
Arm, 8. buffers, 9. planetary reduction gears, 10. bevel-type reversing gears, 11. Handlesets
Specific embodiment
When enabling, hatch door 1 rotation successively drive steel wire rope component 2 stretch out, pulley assembly 3, cable disk component 4, gear pair 5,
Planetary reduction gear 9, bevel-type reversing gear 10 and Handleset 11 rotate, and the torsion of torsion-bar spring component 6 applies resistance, pivoted arm 7
Rotation drives buffer 8 to stretch out application damping.
At closing time, after Handleset 11 engages bevel-type reversing gear 10, operator rotates backward Handleset 11, according to
Sub-band dynamic bevel gear steering mechanism 10, planetary reduction gear 9, gear pair 5, cable disk component 4, pulley assembly 3 rotate backward, and make steel wire
Hatch door 1 is closed in the recycling of component 2 of restricting, and is replied with the torsion of torsion-bar spring component 6 and is provided power-assisted, and the revolution of pivoted arm 7 drives buffer 8
Retraction.
