Description
Technical field
The present invention relates to a kind of buffer gear of docking facilities, belong to buffer gear technical field.
Background technology
The modern society reached increasingly in Science and Technology Day, the scope of activities of the mankind have been expanded to space, have worked as this life according to statistics
The number of satellite to be launched every year on average in the range of boundary is at 80-130 or so.But not all satellite can correctly enter
Rail is on active service, central to have satellite failure or damage.These satellites for failing or being abandoned after completion task, will
It is trapped in always in universe, turns into space trash, so not only entail dangers to the safety of other spacecrafts, while can also takes big
The track resources of amount.Therefore, the capture how realized in space Satellite becomes the emphasis of countries in the world concern.
Target satellite capture technique in space has many meanings, such as：
(1) Orbit Transformation：Auxiliary, which is entered the orbit, to be realized to the satellite do not entered the orbit, or auxiliary becomes rail；
(2) in-orbit change is repaired：Repair the satellite to be broken down in space；
(3) maneuverable platform：The supply of fuel is carried out to satellite, extends its service life；
(4) in-orbit protection：On the one hand be for space floating space trash and fragment protected, on the other hand enter
Some military missions of row.
Since study the target satellite docking important in inhibiting in space, then firstly the need of what makes clear be target
Satellite.Target satellite as docking can be divided into cooperation satellite and non-cooperation satellite.So far, domestic and international space articulation into
Work(case, the greatly docking or capture both for cooperation satellite.And due to space non-cooperative satellite be not configured to docking or
Capture and design, the interface dedicated for arresting or docking is not installed.So need to design pickup vehicle, can
Corresponding interface is found on the non-cooperation satellite for needing to capture.While the security of docking operation is contemplated that, accuracy,
The generality of stability and pickup vehicle.
Meanwhile when capturing satellite in space and arresting the target satellite of free floating, always have certain probability and exist
Rebounded caused by rigid collision between capture satellite and target satellite, can also existed due to target caused by rigid collision
Satellite and the phenomenon of docking facilities damage.In order to avoid situation as appearance, submissive docking that research satellite is arrested control and
Passive compliance link just seems very meaningful, especially in capture satellite and target satellite all in free floating state
Under.
Therefore, it is necessary to develop a kind of effective docking buffer gear, can extend contact time, while can also reduce and touch
Hit the peak value of contact force so that whole docking acquisition procedure becomes controllable, so as to aid in realizing that the success to non-cooperation satellite is caught
Obtain and submissive docking.
The content of the invention
The invention aims to solve the above-mentioned problems of the prior art, i.e., non-cooperation satellite is in space articulation mistake
Due to rigid collision in journey, cause impact contact force excessive, influence to dock control, and may cause to target satellite and right
The damage of connection device.And then provide a kind of buffer gear of docking facilities.
The purpose of the present invention is achieved through the following technical solutions：
A kind of buffer gear of docking facilities, including：Bearing inner sleeve, axle sleeve, axle, forward flange, axle drive end bearing bracket, bearing axle,
End cap, bearing outside, bearing case, connecting plate, gravity compensation block, front casing, copper sheathing, rear casing, axle sleeve end cap, shaft rear end

Bobbin is held and ball bearing, and the front end of the front casing is connected with the rear end of bearing case, the rear end of front casing and rear casing
Front end is connected, and the rear end of rear casing is connected with flange, and axle sleeve is arranged in front casing, and axle is arranged in axle sleeve, axle and axle sleeve
Between rear side be provided with copper sheathing, the rear end of axle is provided with shaft rear end lid, and the front side between axle and axle sleeve is provided with linear bearing, axle sleeve
Rear end be connected with the front end of axle sleeve end cap, axle sleeve end cap flange, axle sleeve end cap flange are fixed with the rear end of axle sleeve end cap
Be provided with axle spring, damper sleeve and damper pull bar grafting between shaft rear end lid, the tail end of damper sleeve with it is rear outer
Shell phase connects, and the tail end of damper pull bar is connected with axle sleeve end cap flange, is provided between damper sleeve and damper pull bar
Radial spring, gravity compensation block are sleeved on the axle sleeve in front casing, and the front end of axle sleeve is connected with the rear end of axle drive end bearing bracket, preceding
The centre position of flange is connected with the front end of axle, and the periphery of forward flange is connected with the front end of axle drive end bearing bracket, connecting plate installation
On the curved surface of front casing front end, bearing outside is arranged in bearing case, and end is connected between bearing outside and bearing case
Lid, the end cap between bearing outside and bearing case are provided with disc spring group, two bearing axles, two axles are provided with bearing outside
Axial symmetry setting is held, is set in ball bearing in bearing axle, the outer of ball bearing is set on universal joint, and axle sleeve is provided with
Two symmetrical bearing installation axles, the interior of ball bearing are set in the bearing installation axle, and the overcoat of ball bearing is by bearing
Set is arranged on universal joint, and four ball bearings are set in cross.
It is as follows using the present invention capture satellites coupling course of work：Capture the control entrance of passing of satelline ground and target satellite
Same rail, if then two satellite relative positions meet the condition of docking with posture, now accordingly referred to by given capture satellite
Order starts docking procedure.In this stage buffer mechanism in addition to maintaining the stabilization of docking facilities, any control will not be carried out.
In the specifically docking stage, capture satellite, close to target satellite, is captured on satellite under the control of docking instruction
Docking facilities expansion head will enter in target satellite jet pipe, and contact-impact occurs, and due to the presence of buffer gear, collide
Expansion head afterwards will enter target satellite jet pipe neck along jet pipe inclined-plane.Capture satellite relative target satellite moves on, and makes
Docking facilities expansion head enters jet pipe neck and opened, and the separation of limitation capture satellite, completes capture docking.
In whole docking operation, the main function of buffer gear is：After the device expansion head that achieves a butt joint contacts with jet pipe
Buffering, and finally when both have coaxiality error, buffer gear can realize the compensation of error.Rank is collided in docking
Section, buffer gear can be realized buffering axially and radially by contained spring and copper sheathing (producing damping), reduce impact force
Peak value, while extend contact time.And at the end of last docking, if coaxiality error be present with jet pipe in docking facilities
When, buffer gear can realize the compensation of error by the big rigidity disc spring group between bearing case and bearing outside.
The present invention reduces impact contact force peak value by designing a set of buffer gear, extends the docking making contact time,
Auxiliary realizes the submissive docking of non-cooperation satellite.In addition, non-cooperation satellites coupling device involved in the present invention is using swollen
Tight hair style jet pipe acquisition equipment, the acquisition equipment have small volume, and topographies satellite jet pipe, coupling mechanism force is big, small excellent of stroke
Point.
The buffer gear that the present invention designs mainly coordinates the docking operation of docking facilities, it is therefore intended that auxiliary docking facilities exist
Smoothly enter target satellite jet pipe in docking operation, prevent from flicking or damaging because impact contact force is excessive.
