Abstract
The ball-type ultralow temperature mirrored sides supporting device of astronomical telescope, it is characterised in that the structure of this mirrored sides supporting device is: the surrounding of primary mirror of astronomical telescope lens barrel, is provided with the U-lag fitting in telescope circle mirror external cylindrical surface, is full of little steel ball in this U-lag.Prioritization scheme is the little steel ball using Φ 4.The ball-type ultralow temperature mirrored sides supporting device of the astronomical telescope of the present invention, lever weighting structure in prior art can be overcome more complicated, take up space big, flexible steel band can only use at a fixed-direction and hydrargyrum band supports the deficiency that may not apply under low temperature, can work under the ultralow temperature of the subzero 85 ° of C of antarctic zone using the present invention as the astronomical telescope of collateral support.
Description
Technical field
The present invention relates to a kind of telescope surface bearing structure, be specifically related to a kind of can work under ultralow temperature, profit
With ball as circle flat sides surface bearing gravity, the ball-type ultralow temperature mirrored sides supporting device of astronomical telescope.
Background technology
In the structure of astronomical telescope major optical parts primary mirror designs, primary mirror to be made points to difference in telescope work
Keep its accurate face shape constant during it district, it is necessary to use accurate supporting system, to bear minute surface along being perpendicular to minute surface direction
Gravity is referred to as bottom support.Should bear again the mechanism along the gravity being parallel to minute surface direction, referred to as side bearing simultaneously.Continue to use in the past
Side bearing have lever weighting, flexible steel band and hydrargyrum belt.
Lever weighting structure is more complicated, takes up space big.Flexible steel band can only use at a fixed-direction.Thus hydrargyrum band is
A kind of well structure.Hydrargyrum belt supporting structure is simple, and volume is little, utilizes hydrargyrum can well fit than the buoyancy of great generation
Answer the cross component of the primary mirror Gravity changer of different directions.
Can not produce corresponding buoyancy owing to hydrargyrum at low temperatures can solidify, the supporting of hydrargyrum band cannot be applied to low temperature
Under, the especially use in polar region telescope.
Mirrored sides supporting scheme of the prior art, is unsuitable for making in the structure of antarctic astronomical telescope substantially
With.
Summary of the invention
In order to make up the deficiencies in the prior art, it is an object of the invention to provide one and utilize ball as circle flat board lateral bolster
Bearing capacity, astronomical telescope ball-type ultralow temperature mirrored sides supporting device.This structure can overcome lever in prior art
Heavy hammer structure is more complicated, take up space big, flexible steel band can only use at a fixed-direction and the supporting of hydrargyrum band may not apply to low
Deficiency under Wen, can work using the present invention as the astronomical telescope of collateral support under antarctic ultralow temperature.
The technical scheme completing foregoing invention task is, the ball-type ultralow temperature mirrored sides supporting machine of a kind of astronomical telescope
Structure, it is characterised in that the structure of this mirrored sides supporting device is: the surrounding of primary mirror of astronomical telescope lens barrel, is provided with and fits in prestige
The U-lag (cross section is the circular trough of U-shaped) of remote mirror circle mirror external cylindrical surface, is full of little steel ball in this U-lag.
The structure of the present invention is told and is similar to hydrargyrum band of the prior art；Simply hydrargyrum band is replaced with the circle of steel construction
Being full of little steel ball in groove, utilize little steel ball to replace hydrargyrum, little steel ball the most mutually extrudes and has lateral weight component,
Produce the towing force to mirror.Thus play side bearing effect.
Further improvement of the present invention, has a following prioritization scheme:
1, described little steel ball, it is proposed that use the little steel ball of Φ 4；
2, it is filled with low temperature fat between the little steel ball of described each；To reduce frictional force between steel ball；
3, the width of described U-lag (circular trough), about 1/2 for mirror average thickness H (should regard mirror material proportion
Depending on)；Concrete a size of ρ/5, wherein, ρ is the proportion of telescope specular material.(proportion 5 is owing to steel ball has gap according to reality
Survey equivalent, learn that proportion is about about 5.)
Illustrate: with reference to the computing formula of hydrargyrum bandwidth: b=G/ π R2ρ1, G is mirror weight, ρ1For the medium ratio supported
Weight；And G=π R2Hρ2, in formula, H is mirror average thickness, ρ2For mirror material density；Therefore upper two formula are had to understand: b=H
ρ2/ρ1。
Telescope specular material generally glass is made proportion and is about 2.5.And little steel ball material proportion is 7.8, it is contemplated that
Having the factor in gap, actual duty cycle is heavily about 5.So wide the 2.5/5 of the mirror average thickness H that should be of this side bearing is i.e. 1/
About 2, i.e. can get relatively satisfactory lateral supporting forces.
4, described U-lag is rigidly connected with mirror cell, leaves the gap less than steel ball radius outside the mirror face of cylinder.
The ball-type ultralow temperature mirrored sides supporting device of the astronomical telescope of the present invention, it is possible to overcome lever in prior art
Heavy hammer structure is more complicated, take up space big, flexible steel band can only use at a fixed-direction and the supporting of hydrargyrum band may not apply to low
Deficiency under Wen, can work using the present invention as the astronomical telescope of collateral support under antarctic ultralow temperature.This invention
The minimum temperature used is grease operating temperature between steel ball and steel ball, can be at subzero 85 ° of C.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Fig. 2 is the side view of Fig. 1.
Detailed description of the invention
