Description
Technical field
The invention belongs to nuclear power station service technique fields, and in particular to a kind of bearing shell fixed support device.
Background technology
Generator of nuclear power station group include main feed pump, level-one, two level condensate pump, steam-water separation pump etc. large centrifugals pump and
Tens, corresponding motor, these pumps and motor are all to position rotor by bearing shell and bear certain radial load.In order to
Ensure that axis and bearing shell contact are good, everywhere uniform force and rubbing surface oil film is complete, needs to carry out bearing shell careful scraping.?
During scraping, since bearing shell is arc surface, it is not fixed easily, needs a people firmly to pin bearing shell in practical operation, ensure it
It does not shake, another person holds scraper and carries out scraping, and whole process is bothersome laborious, and efficiency is very low.
Invention content
The object of the present invention is in view of the shortcomings of the prior art, provide a kind of simple in structure, it can effectively solve the problem that and scrape watt-hour axis
Watt it is not fixed easily the bearing shell fixed support device of the problem of support.
The technical scheme is that：
A kind of bearing shell fixed support device, including square chest, convex sliding block, v block, bearing shell, double threaded screw, supporting rod and pressure
Plate, it is characterised in that：The square chest upper surface is equipped with convex slide block slot, and a v block slot is equipped among two convex slide block slots,
Two convex sliding blocks are respectively arranged in two convex slide block slots, and v block is set in v block slot, and the bearing shell is set on v block
End；Two supporting rods are set to one end close to square chest edge on the outside of two v block slots；On each convex sliding block
Being spirally connected, there are one double threaded screws；Described two pressing plates are respectively sleeved on the double threaded screw and supporting rod of homonymy.
The supporting rod is equipped with nut, and the nut is located at pressing plate lower end；The double threaded screw is equipped with nut, described
Nut is set to pressing plate upper end.
The pressing plate is pressed in bearing shell edge.
The beneficial effects of the invention are as follows：
1, a kind of bearing shell fixed support device of the invention is simple in structure, easy to use；
2, a kind of bearing shell fixed support device of the invention can effectively solve the problem that bearing shell fixes the difficult problem of support, and
Time saving, laborsaving, work efficiency is high；
3, a kind of bearing shell fixed support device of the invention can adjust adaptation manually according to bearing shell size, meet different model
Fixation problem when bearing shell scraping；
4, a kind of bearing shell fixed support device of the invention will not cause to damage to bearing shell.
Description of the drawings
Fig. 1 is that a kind of bearing shell fixed support device uses schematic diagram；
In figure：1. square chest；2. convex sliding block, 3.V sections, 4. bearing shell, 5. double threaded screw, 6. supporting rods, 7. pressing plates, 8. spiral shells
It is female.
Specific implementation mode
The present invention is further introduced with embodiment below in conjunction with the accompanying drawings：
A kind of bearing shell fixed support device, including square chest 1, convex sliding block 2, v block 3, bearing shell 4, double threaded screw 5, support
Bar 6 and pressing plate 7, it is characterised in that：1 upper surface of the square chest is equipped with convex slide block slot, and one is equipped among two convex slide block slots
V block slot, two convex sliding blocks 2 are respectively arranged in two convex slide block slots, and v block 3 is set in v block slot, the bearing shell 4
Set on 3 upper end of v block；Two supporting rods 6 are set to one end close to 1 edge of square chest on the outside of two v block slots；It is described every
Being spirally connected on a convex sliding block 2, there are one double threaded screws 5；Described two pressing plates 7 are respectively sleeved in double threaded screw 5 and the support of homonymy
On bar 6.
The supporting rod 6 is equipped with nut 8, and the nut 8 is located at 7 lower end of pressing plate；The double threaded screw 5 is equipped with nut
8, the nut 8 is set to 7 upper end of pressing plate.
The pressing plate 7 is pressed in 4 edge of bearing shell.
Embodiment
Two v blocks are slid into square chest groove, according to distance between various sizes of bearing shell adjustment v block, bearing shell
Both ends circle cambered surface frame is on v block.Two convex sliding blocks are slid into the square chest groove of the adjacent both sides of bearing shell, since bearing shell is straight
Diameter is not of uniform size, can be parallel or diagonally place sliding block as needed.Double threaded screw short thread one end is screwed in into sliding block.Supporting rod
It screws on nut and is put in double threaded screw both sides, while pressing plate being sleeved on supporting rod and double threaded screw so that pressing plate one end is pressed in axis
Watt edge.Nut is tightened on double threaded screw pushes down pressing plate.It checks whether whole device is stablized, bearing shell can then be scraped
It grinds.
The present invention is explained in detail above in conjunction with drawings and examples, but the present invention is not limited to above-mentioned implementations
Example, within the knowledge of a person skilled in the art, can also do without departing from the purpose of the present invention
Go out various change.The prior art can be used in the content not being described in detail in the present invention.
