Description
Technical field
The present invention relates to a kind of supporting systems of mechanical rotation axis system, and in particular to a kind of novel large-scale South Pole telescope
Azimuth axis supporting system.
Background technique
South Pole scientific investigation statistics indicate that: Antarctic region atmosphere is thin, cold, dry, dust is few, and atmospheric turbulance is few, view is peaceful
It spends, it is often more important that be able to carry out the continuous astronomical observation (polar night) up to the several months in Antarctic region, and ambient light contamination is few.
These features make the astronomical observation condition in the South Pole be incomparable elsewhere on the earth.So astronomical boundary is all in the world
South Pole astronomy is being greatly developed, Dome A of the China also in the South Pole has started relevant astronomical research, successively in South Pole Dome A
It is mounted with the medium and small astronomical telescope such as CSTAR, AST3, these apertures of mirror of looking in the distance are small, and it is light-weight, using traditional mechanical axis
Hold bearing.With the propulsion of astronomical research, need to build large-scale altitude azimuth form astronomical telescope, large-scale altitude azimuth form day in the South Pole
Literary telescope configuration schematic diagram is as shown in Figure 1, lens cone for telescope 1 is supported on two by the bearing support 3 of the altitude axis 2 on its both sides
On side yoke 4, two yokes 4 on both sides are passed to weight on azimuth rotating platform 5, for amechanical angle, the load-bearing of azimuth rotating platform 5
The diameter D of bearing 6 should be suitable with the span of both sides yoke, i.e., load-bearing bearing 6 should be in the underface of both sides yoke, this sample prescription
The mechanical property of position turntable 5 is best, and is conducive to the design of its structure.The radial positioning of azimuth rotating platform 5 passes through a pair of of angular contact ball
Bearing 8 realizes the radial positioning of azimuth axis 9.For large-scale astronomical telescope, orientation load-bearing bearing 6 generallys use liquid
Body hydrostatic bearing is had the advantages that as follows using this hydrostatic bearing:
1) compared with traditional mechanical ball bearing, the diameter of hydrodynamic journal liquid polymers can be made greatly, can satisfy described above
Orientation load-bearing bearing major diameter requirement.
2) coefficient of friction of hydrodynamic journal liquid polymers only has the 1/10 of mechanical bearing, advantageously reduces large-scale astronomical in this way and looks in the distance
The friction torque of mirror orientation rotation, and then reduce driving energy consumption.
But since the environment temperature in the South Pole is very low, winter minimum temperature reaches -89 DEG C.It is not available traditional large telescope
On the hydrodynamic journal liquid polymers that generally use.For this reason, it may be necessary to have a kind of technical solution, to solve South Pole large-scale astronomical telescope orientation
Support the following problem (the application is illustrated for 3 meters of aperture of mirror to look in the distance) faced:
1) it rotationally supports and is relatively large in diameter, at 4 meters or more.
2) moment of friction that bearing generates wants small, adapts to the requirement of South Pole energy supply anxiety.
3) supporting stabilizer can be realized the stable tracking of South Pole astronomical telescope and be directed toward.
The technical solution that can satisfy above-mentioned requirements is not yet found in the prior art.
Summary of the invention
The object of the invention is to the support problems in order to solve above-mentioned 4 meters or more super-large diameters, provide a kind of large-scale south
The supporting system of pole telescope azimuth axis, which, which rotationally supports, is relatively large in diameter, at 4 meters or more；Supporting system bearing
The moment of friction of generation is small, can adapt to the requirement of South Pole energy supply anxiety；The supporting system supporting stabilizer, can be realized south
Astronomical telescope stable tracking in pole is directed toward.
The technical solution for accomplishing the above inventive task is that: a kind of supporting system of large size South Pole telescope azimuth axis is looked in the distance
Mirror lens barrel is supported on the yoke of both sides by the bearing support of the altitude axis on its both sides, and two yokes on both sides are the weight side of passing to
Position turntable on, which is characterized in that the bind mode between the azimuth rotating platform and pedestal is: pedestal be equipped with arc-shaped guide rail and with
Matching several sliding blocks；The top of the sliding block and the bottom of the azimuth rotating platform are fixed.
In other words, the invention proposes supporting schemes as shown in Figure 2: being matched therewith using arc-shaped guide rail 11 and 6
The bearing that sliding block 10 forms, to replace the hydrodynamic journal liquid polymers 6 of orientation load-bearing in Fig. 1 and the angular contact ball bearing group of radial positioning
8.Since the whole circle of the arc-shaped guide rail of super-large diameter can be spliced by multiple segmental arcs, so diameter D can be made big in Fig. 2.
The maximum gauge of off-the-shelf can reach 6 meters at present, and whole circle is spliced (as shown in Figure 3) by 6 60 ° of segmental arc, pass through spelling
Spliced less than 50 microns of the whole circle jerk value (micron order) of equipment is connect, is much higher than 3 meter level Aperture Telescopes and orientation is supported
Requirement (3 meter level bores require at 80~100 microns).Since telescope weights above passes to orientation by the yoke on both sides
Turntable, so respectively arranging 2 sliding blocks in the lower section of both sides yoke to undertake weights above (0 ° and 180 ° of two sides in such as Fig. 3
To), in order to improve the stability and rigidity of bearing, 1 sliding block is also respectively arranged respectively on 90 ° and 270 ° of directions.Sliding block 10
It is fixed on azimuth rotating platform 5 by joint bolt 12, arc-shaped guide rail 11 is fixed on pedestal 7 also by joint bolt 13, fixation side
Formula is as shown in Figure 4.Then according to arc-shaped guide rail product hand, if arc-shaped guide rail diameter D is 4 meters, single sliding block with matching
Be capable of carrying a load of 14 tons, if arranging 2 sliding blocks as shown in Figure 3, total load capacity of 4 sliding blocks below each yoke
It is 56 tons, and the weight of 3 meter level telescope rotating parts is at 40 tons or so, therefore, using this arc-shaped guide rail as large size
No matter the bearing of telescope can meet the requirement of South Pole large telescope, not only solve from load-bearing capacity or running accuracy
It has determined the problem of big rotating diameter, has also eliminated radial orientation angle contact ball bearing group and location fix axis in Fig. 1.
Prioritization scheme of the invention is as follows: the weight of large telescope rotating part is very heavy, and such as 3 meter level Aperture Telescopes turn
The weight of dynamic part will generate very big frictional force at 40 tons or so in this way between guide rail and sliding block, and then generate very big
Friction torque.Very big friction torque has two for large-scale South Pole telescope: first is that South Pole energy shortages,
Friction torque is intended to greatly very big driving energy consumption, causes energy supply problem；Second is that friction torque also implies that greatly
The undulate quantity of friction torque is also larger in whole circle, will affect the tracking accuracy of telescope in this way, cannot achieve high-precision tracking.
For this problem, the invention proposes schemes as shown in Figure 5, are respectively arranged with two pairs in the inner ring of arc-shaped guide rail and outer ring
Permanent magnetism circle, each pair of permanent magnetism circle are respectively D by diameter1And D2Upper permanent magnet and lower permanent magnet constitute the (D1Less than arc-shaped guide rail
Diameter；The D2Greater than the diameter of arc-shaped guide rail), the upper permanent magnet constitutes permanent magnetism circle unloading rotor；The lower permanent magnet
Constitute permanent magnetism circle off-load stator；Repulsion each other between the upper and lower permanent magnet of two pairs of permanent magnetism circles, is unloaded by permanent magnet expulsive force
It carries.The weight of two circle permanent magnet expulsive force unloadings is the 80% of telescope rotating part weight, and 20% weight is still undertaken by arc-shaped guide rail,
Moment of friction is not only greatly reduced in this way, but also is able to achieve the high-precision positioning function of arc-shaped guide rail.Unloading permanent magnetism circle is all by turning
Son 14 and stator 15 are composed of, and it is a whole circle, but due to existing processing that stator, which is similar to the bearing arc-shaped guide rail of front,
The considerations of condition and replacement maintenance in the future, whole delineation is spliced by several permanent magnet modules as shown in FIG. 6, splicing module
The upper surface of pedestal 7 is fixed on by fixing screws 16 respectively, the connecting method of inside and outside two circle is similar, and the size of splicing module can
According to diameter D1(D2), off-load weight and permanent magnetism processing technology etc. determine.Equally from the point of view of mechanics, weight is mainly
It is transmitted to azimuth rotating platform by the yoke on both sides, therefore, is mounted with to draw a circle to approve sub- phase with permanent magnetism respectively below both sides yoke 4
6 p-m rotor 14(of pairing are as shown in Figure 7), in order to guarantee stability and the rigidity of structure, the vertical direction of yoke on both sides
Upper (90 ° and 270 ° of directions in Fig. 7) are also respectively provided with 2 p-m rotors 14.It is solid that p-m rotor module equally passes through screw 17
It is scheduled on the lower surface of azimuth rotating platform 5.Permanent magnetic is directly proportional to the volume of permanent-magnet material, so load forces are unloaded in order to improve, Fig. 6 and figure
In 7 permanent magnet module all be use 1 screw fix, in order to be entirely limited permanent magnet module rotation and installation convenience,
It is machined with concave ring respectively in the lower surface of base upper surface and azimuth rotating platform, as shown in figure 8, being used to position permanent magnet module, concave ring
Size according to the outer dimension of permanent magnet module determine.
