Description
Technical field
The invention belongs to metallurgical engineering technical fields, and in particular to a kind of backing roll dress of superconduction external rotor electric machine dragging
It sets.
Background technique
Currently, the milling train and straightener in continuous rolling production line both at home and abroad, is all the backing roll using interlaced arrangement, that is, adopts
Bearing working roll is carried out with passive bearing roller, is had the following disadvantages：1. it is broadening with rolling width, upper and lower working roll
Upper and lower backing roll, the roll-force or straightening force being subject to are unevenly distributed, and backing roll is caused to deform, rotation abrasion aggravation, maintenance at
This increase；2. the diameter of backing roll increases as rolling stock intensity increases, milling train or straightener spatial arrangement difficulty increase.
Summary of the invention
It is an object of the present invention to provide the support roller devices of superconduction external rotor electric machine dragging, can deposit efficiently against the prior art
The shortcomings that.
The invention is realized in this way as shown in Figure 1, it is characterized in that:It include vacuum check valve 1, roller set 2, outer cylinder body
3, left and right annular end cap 4.4', inner cylinder tube 5, superconduction external rotor electric machine 6,3D printing space frame 7, connection relationship are：Superconduction
External rotor electric machine 6 is standard set-up, 5 sets of inner cylinder tube outside superconduction external rotor electric machine 6, outer cylinder body 3 is sleeved on the outer of inner cylinder tube 5
On circumference, left and right annular end cap 4.4' is connect by left and right screw group with inner cylinder tube 5 and outer cylinder body 3, forms annular interior cavity 8,
Annular interior cavity 8 is provided with 3D printing space frame 7, and 3D printing space frame 7 is the space truss knot using 3D printer printing
Structure, roller set 2 are sleeved on the outer circumference surface of outer cylinder body 3, are equipped with the vacuum being connected to annular interior cavity 8 in the middle part of right annular end cap 4'
Check valve 1, by vacuum check valve 1 by 8 vacuum pumping of annular interior cavity.
Advantage of the present invention and good effect are：
1. due to being dragged with superconduction external rotor electric machine, it can be achieved that outer rotor passes through relative to stator superconductive suspension and controls stator
The control of backing roll bearing capacity is realized in magnetic field, and then realizes dynamic control backing roll bearing capacity.
2. being formed in ring-type due to being connect by left and right screw group with inner cylinder tube and outer cylinder body using left and right annular end cap
Chamber, annular interior cavity are provided with 3D printing space frame, by vacuum check valve by annular interior cavity vacuum pumping, can solve outside superconduction
Temperature field difference between rotor electric machine and backing roll, conducive to the industrial applications of superconductor technology.
3. realizing space bearing using 3D printing technique to make built-in annulus vacuum layer thermal resistance circle set that there is supporting structure
Structure both ensure that vacuum heat-insulation, in turn ensure reasonable supporting role, prevent the effect deformation invagination by external support power.

Specific embodiment
It is elaborated with reference to the accompanying drawing by preferred embodiment to the present invention.
By the device of the invention interlaced arrangement in the upper and lower of the upper and lower working roll of strip, staggeredly cloth in the prior art is replaced
The backing roll set, and staggeredly support；As shown in Figure 1, outer cylinder body 3, left and right annular end cap 4,4' and the assembling of inner cylinder tube 5 circularize
3D printing space supporting structure 7 is packed into annular housing 8 by cavity 8, and 3D printing space frame 7 is printed using 3D printer
Space truss structure, guarantee reasonable supporting role, annular housing 8 vacuumized by vacuum check valve 1, it is true to reach thermal resistance
Altitude forms superconductivity magnetic levitation structure between superconduction motor stator for outer rotator and outer rotor, by controlling motor stator electric current,
It realizes the large and small control of backing roll bearing capacity, guarantees the supporting role of working roll.
