Temperature is needed to be widely varied in range at -180 DEG C to 40 DEG C now, the geometric accuracy of mechanical structure varies less, such as axis
The running accuracy of system.Since the material of mechanical structure component is different, the linear expansion coefficient of temperature change is different, mechanism member
Relative position necessarily changes, it is now desired to the variation of position is overcome by temperature compensation mechanism, it is required several to ensure
What position precision.
Summary of the invention
In order to solve the above technical problems, needing obtaining means we have proposed a kind of temperature change synchroballistic shafting
When temperature is widely varied, the running accuracy of shafting still maintains original high-precision.
In order to achieve the above objectives, technical scheme is as follows:
A kind of temperature change synchroballistic shafting, including main shaft, axle sleeve, compensation set, matrix, terminal pad and ring flange；Institute
Main shaft is stated equipped with axle sleeve, the sleeve outer surface is taper；The axle sleeve is equipped with compensation set, and compensation set inner cavity is cone
Shape, and its taper is consistent with the sleeve outer surface taper in inner cavity corresponding matching；Described and compensation set cooperation is matrix,
And it is provided with terminal pad outside the main shaft of the axle sleeve, compensation set and matrix one end, in the axle sleeve, compensation set and matrix
Ring flange is provided with outside the other end；The main shaft, axle sleeve and ring flange are steel material, the compensation set, matrix and connection
Disk is aluminum material.
Preferably, the compensation set is tightly fastened by the terminal pad in its end and the compensation set and matrix.
Preferably, the axle sleeve is tightly fastened with the ring flange, and the ring flange is tightly fastened with matrix.
Preferably, the main shaft is radial is equipped with rolling bearing with axial.
Through the above technical solutions, the present invention passes through in the more one layer of cone compensation sets of axle sleeve outer ring design, axle sleeve bus
According to pressing after axial dimension, radial dimension actual measurement, different materials linear expansion coefficient is determining, and compensation covers and connects with the gradient of axial line
It connects disk and matrix fastens, the taper outer circle and compensation set taper inner corresponding matching, axle sleeve and ring flange of axle sleeve fasten, ring flange
It is fastened with matrix.Axis system is radial still can to take rolling bearing with axial, when temperature is widely varied, the rotation of shafting
Turn precision and still maintains original high-precision.Be suitble to the common apparatus without isoperibol, high precision apparatus, vacuum environment equipment and
Space technology equipment etc..

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of temperature change synchroballistic shaftings, and which overcome the shadows of temperature change shaft precision
It rings.
Below with reference to embodiment and specific embodiment, the present invention is described in further detail.
Embodiment
As shown in Figure 1, a kind of temperature change synchroballistic shafting, including main shaft 6, axle sleeve 1, compensation set 4, matrix 3, connection
Disk 2 and ring flange 5；Axle sleeve 1 is arranged on the main shaft 6,1 outer surface of axle sleeve is taper；The axle sleeve 1 is equipped with compensation
Set 4, it is taper that the compensation, which covers 4 inner cavities, and its taper and the 1 outer surface taper of axle sleeve are consistent in inner cavity corresponding matching；
The compensation covers 4 outer circles and matrix 3 cooperates, and is provided in 6 outer ring of main shaft of the axle sleeve 1, compensation set 4 and 3 one end of matrix
Terminal pad 2 is provided with ring flange 5 outside the other end of the axle sleeve 1, compensation set 4 and matrix 3；The main shaft 6,1 and of axle sleeve
Ring flange 5 is steel material, and the compensation set 4, matrix 3 and terminal pad 2 are aluminum material.
Wherein, the compensation set 4 is tightly fastened by the terminal pad 2 in its end and described matrix 3；The axle sleeve 1
It is tightly fastened with the ring flange 5, the ring flange 5 is tightly fastened with matrix 3；The main shaft 6 is radial to be equipped with rolling with axial
Dynamic bearing.
The cooperation of main shaft 6 and axle sleeve 1 is usually cylinder, now in the more one layer of cone compensation sets of 1 outer ring of axle sleeve design
4, the gradient of 1 outer circle bus of axle sleeve and axial line is according to pressing different materials linear expansion coefficient after axial dimension, radial dimension actual measurement
It determines.Using the face A as benchmark face, the line of axial dimension expands variation delta L, and the line equal to small end head diameter dimension expands variable quantity
The half of Δ D.
Need obtaining means when temperature is widely varied, geometric accuracy (i.e. geometric position) variation is small to keep high-precision
Degree, such as the axis of rotation of shafting, axial line are equal to one of the variation delta D of small end head diametrically in axial variation delta L
Half.
It can be seen that this temperature change synchroballistic shafting passes through in the more one layer of cone compensation sets of 1 outer ring of axle sleeve design
4, the gradient of 1 bus of axle sleeve and axial line is determined according to after axial dimension, radial dimension actual measurement by different materials linear expansion coefficient,
Compensation set 4 is fastened with terminal pad 2 and matrix 3, taper (inclined-plane) outer circle and compensation 4 taper inner corresponding matchings of set of axle sleeve 1, axis
Set 1 is fastened with ring flange 5, and ring flange 5 and matrix 3 fasten.Axis system is radial still can to take rolling bearing with axial,
When temperature is widely varied, the running accuracy of shafting still maintains original high-precision.It is suitble to the common apparatus without isoperibol,
High precision apparatus, vacuum environment equipment and space technology equipment etc..
Above-described is only a kind of temperature change synchroballistic shafting preferred embodiment of the invention, it is noted that
For those of ordinary skill in the art, without departing from the concept of the premise of the invention, several changes can also be made
Shape and improvement, these are all within the scope of protection of the present invention.
