Description
Technical field
The utility model relates to continuous casting machine technical field, especially a kind of continuous casting machine crystallizer foot roll assembly.
Background technique
Conticaster crystallizer is the crystallization process equipment that the molten steel of liquid is become after cooling to slab by pressure, and sufficient roller is total
It at the bottom for being mounted on crystallizer, is mainly made of sufficient roller, sliding bearing, eccentric shaft, sufficient roller is in hollow structure, and sliding bearing exists
Inside sufficient roller, excentric sleeve is loaded on the centre of sliding bearing, is machined with lubricating grease channel and and greasing hole phase in eccentric axis center
Logical, the higher spray by cooling water of sliding bearing ambient temperature, lubricating grease is easy carbonization and goes bad, and sliding bearing is mostly copper
The therefore coefficients of expansion different from eccentric shaft material are also different, in addition when steel slag is easy to enter the inner surface card resistance phenomenon of sliding bearing
Often occur, leads to sufficient roller failure frequent occurrence.The continuous casting crystallizer foot-roller of this structure, sliding bearing service life is short, no
It is able to achieve the multiple casting sequence of continuous casting, primary cold line metapedes roller serious wear, continuous-casting foot roll and the fan-shaped section changed is to the essence of arc
Degree reduces the precision for leading to influence continuous casting billet, causes continuous casting billet surface scratching, also will cause the accidents such as bleed-out when serious.
Utility model content
The purpose of this utility model is to provide a kind of continuous casting machine crystallizer foot roll assemblies, to solve existing sufficient roller rotation
Not flexible and eccentric shaft locking leads to that easily stuck problem cannot be operated.
To achieve the above object, the utility model provides the following technical solutions: a kind of continuous casting machine crystallizer foot roll assembly, packet
Include sufficient roller, axle sleeve and eccentric shaft, sufficient roller inner hollow is set with axle sleeve, eccentric shaft is set with inside axle sleeve, it is characterized in that: axle sleeve is from upper
Helicla flute is axially arranged under, spiral groove depth is equal with half bush wall thickness, and eccentric shaft surface side is equipped with threaded hole, and centre is equipped with axis
To greasing hole, eccentric shaft middle part is radially provided with greasing hole, and axial greasing hole intersects with radial greasing hole and forms T-shape three
It is logical, greasing groove is equipped among eccentric shaft, greasing groove outer diameter is less than eccentric shaft outer diameter.
Preferably, the helicla flute spiral on the axle sleeve is away from the greasing groove length being less than on eccentric shaft middle part.
Preferably, one of described spiral groove width 0.5mm-1.5mm.
Preferably, the axle sleeve selects 663 tin bronzes, 555 tin bronzes or 6.5-0.1 phosphor bronze table.
Preferably, the eccentric shaft selects stainless steel part.
The utility model compared with prior art, has the advantages that
The utility model has preferable lubricant effect and wearability compared with original spare part, improves cold and hot expansion loop
Bonding, the stuck phenomenon of eccentric shaft are reduced in border, can effectively prevent slab from scratching and become with water chestnut, and the simple production cost of structure is low,
With reliable practical value.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model；
Fig. 2 is the component diagram of the utility model；
Fig. 3 is the component diagram of the utility model；
In figure: 1 sufficient roller, 2 axle sleeves, 3 eccentric shafts, 4 helicla flutes, 5 threaded holes, 6 axial greasing holes, 7 radial greasing holes, 8 three
Logical, 9 greasing grooves.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to shown in Fig. 1-Fig. 3, the utility model provides the following technical solutions: a kind of continuous casting machine crystallizer foot roll is total
At including sufficient roller 1, axle sleeve 2 and eccentric shaft 3, sufficient 1 inner hollow of roller are set with axle sleeve 2, are set with eccentric shaft 3, axle sleeve 2 inside axle sleeve 2
It is axially arranged with helicla flute 4 from top to bottom, helicla flute 4 is deep equal with 2 thickness of axle sleeve, and 3 surface side of eccentric shaft is equipped with threaded hole 5,
Centre is equipped with axial greasing hole 6, and 3 middle part of eccentric shaft is radially provided with greasing hole 7, and axial greasing hole 6 is intersected with radial greasing hole 7
And T-shape threeway is formed, greasing groove 9 is equipped among eccentric shaft 3,9 outer diameter of greasing groove is less than eccentric shaft outer diameter.
4 spiral of helicla flute on the axle sleeve 2 is away from 9 length of greasing groove being less than on 3 middle part of eccentric shaft.
The 4 width 0.5mm-1.5mm of helicla flute.
The axle sleeve 2 selects one of 663 tin bronzes, 555 tin bronzes or 6.5-0.1 phosphor bronze table.
The eccentric shaft 3 selects stainless steel material.
Working principle of the utility model is: being provided with helicla flute 4 on axle sleeve 2, lubricating grease passes through axial greasing hole 6 through diameter
