Description
Technical field
The utility model relates to steel rolling equipment technical field, specifically a kind of aligning roller assembly.
Background technique
It, usually will be to heat before pickling in order to improve the pickling efficiency of hot-strip in the pickling unit of steel rolling equipment
It rolls belt steel surface and carries out scale breading processing.Straightener can not only align strip steel head and ontology, in straightening process, strip
By alternating bending, moreover it is possible to keep the oxide skin of belt steel surface loose, to improve the pickling efficiency of hot-strip.
But pickling unit work condition environment is poor, there is acid mist, spent acid, regeneration off gases, metal fragment and powder etc., straightener work
After one period, the lip of straightening roll sealing ring fails, and foreign matter can invade Bearing inner easily, seriously affects aligning roller assembly
Service life.
Utility model content
In order to overcome the deficiencies of the prior art, the purpose of the invention of the present invention is to provide a kind of aligning roller assemblies, with reality
Now improve the purpose of straightening roll service life.
For achieving the above object, the both ends of the utility model straightening roll are respectively provided with operation side shaft holder and transmission side
Bearing block is driven in side shaft holder and is equipped with self-aligning roller bearing, and saturating cover bolt one is mounted in the outside of transmission side shaft holder, thoroughly
Sealing ring one is had in lid, transparent cover is equipped with oil nozzle, and spacer ring is bonded with the outer ring of self-aligning roller bearing, transparent cover, the head of straightening roll
Portion have key, end cap one and bolt two, end cap one, flange, outer ring, backing plate, self-aligning roller bearing inner ring, inner ring and sealing ring according to
Secondary fitting, transmission side shaft holder inner band have ring-shaped groove and sealing ring two；Aligning roller axis is installed in operation side shaft holder
Hold, for bored cover bolt one mounted in the outside of operation side shaft holder, boring cover is equipped with oil nozzle, spacer ring and self-aligning roller bearing it is outer
Circle, boring cover fitting, the tail portion of straightening roll are equipped with end cap two and bolt two, end cap two, self-aligning roller bearing inner ring, inner ring and sealing
Ring is successively bonded, and operates the inside of side shaft holder with ring-shaped groove and sealing ring two.
The lip of the sealing ring one is bonded with outer ring, and the lip of sealing ring two is bonded with inner ring, is driven in side shaft holder
The ring-shaped groove of side is engaged with sealing ring, is operated the ring-shaped groove on the inside of side shaft holder and is engaged with sealing ring.
Compared with prior art, using double sealing structure, i.e. sealing ring bites the ring on the inside of bearing block to the utility model
Shape groove plays primary seal to bearing, and foreign matter can be effectively prevent to invade Bearing inner；The lip and inner and outer rings of sealing ring
Fitting, plays secondary seal to bearing.It is simple and compact for structure, it can avoid bearing initial failure, greatly improve straightening roll
Service life.
