Description
Technical field
The utility model belongs to tight volume machine field, is assembled more particularly, to a kind of pinch roll.
Background technology
Pinch roll is the vertical collecting region equipment of hot-strip, after finish rolling between last rolling mill and flat bed delivery chain, flat
Between plate conveyer chain and vertical coiler, it is strip will to have turned round vertical strip and be fed forward and will be erect on carrier bar that it, which is acted on,
Five-roll machine and coiling machine are sent respectively, pinch roll serves critical conveying and leads steel effect in this process, so he
Normal operation seem most important.
Pinch roll apparatus mainly includes pinch roll assembling, free roll assembling, motor transmission assembling and cylinder driving assembling, electricity
Machine drives pinch roll rotation, and free roll is adjacent on pinch roll in the presence of cylinder in cylinder driving assembling, pinch roll with from
Strip is clamped by roller together, in the presence of motor, realizes and pinches the purpose that strip is goed ahead.
In the prior art, pinch roll uses single-row tapered roller bearing, the defects of using single-row tapered roller bearing maximum
It is to need to adjust the size of clearance in assembling.The difficulty of assembling is so virtually increased, assembling master worker has also been tested, has stayed
Gap it is too big, the easy vibration of bearing, stay gap too small roller rotate it is dumb, at work if increase heavy burden will go out
The problem of existing roller does not turn, this is problem one.Secondly be exactly bearing occur in assembling it is necessary to consider the lubrication of bearing, although
Bevel gear is among thin oil in this assembling, but it gets along holy remote with bearing, can not meet the lubrication of bearing, institute at all
There is the lubricating system that bearing there must be oneself, we are periodically added using dry oil lubrication using lubricating cup in this structure
Enter, such drier oil will be wrapped among bearing, so as to play a part of lubricating bearing.It is actual but this is perfect condition
Situation is that, because this equipment is in collecting region, roller directly contacts steel band, and temperature of steel strips now is up to 800 DEG C or so, by
So high in residing environment temperature, along with continual machine run, the lubricating grease being added to from lubricating cup in chamber is basic
It is melted into from paste liquid, so in real work, the lubricating system of bearing becomes thin oil lubricant in fact, and below bearing
Any seal form is not selected between casing, so in the case where running at high speed, must so cause lubricating oil all to be flowed toward flowing down
Arrive in pinch roller box body, so there have been two problems, first, oil-free can use around bearing, that necessarily at high temperature can
Burn bearing, the axle is worn to change for that, and not saying wastes time and energy, and also has a strong impact on manufacturing schedule;Secondly it is exactly the lubrication of top
Oil has all been arrived in casing, although the bevel gear in casing is thin oil lubricant, can not fill it up with FCL oil, but producing
In, in order to prevent burn bearing, worker can periodically give bearing oiling, and so oil has all flowed to casing, and the oil in that casing is just
It can be continuously increased, go round and begin again, worker must drain the oil to casing, which adds workload, and generate contradiction, again
Be afraid of top bearing oil starvation, be afraid of to add oil in too many casing full again, so conventional design has irrationality.In summary, improve
This structure is extremely urgent, one to reduce assembling when difficulty, two solve the problems, such as bearing lubrication, and we make as follows to structure
Change.
The content of the invention
In view of this, the utility model is directed to a kind of pinch roll assembling, can solve above-mentioned technical problem.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in:
A kind of pinch roll assembling, including casing, roller, gland, bearing, bevel gear and rotating shaft, the rotating shaft is from bottom to top
Sequentially pass through in casing, gland and roller, bevel gear in casing, rotating shaft through bevel gear, rotating shaft and casing edge it
Between connected by bearing, the locating piece for Horizontal limiting bearing is provided between casing and bearing, locating piece is fixed on casing, presses
Lid is fixed on that casing outer end is spacing to bearing, and gland is secured by bolts in locating piece, and roll end is provided with groove, and gland card is set
In in groove, interconnected lubricant channel is provided with inside locating piece and gland, space is provided between roller and casing, positioned
Block is extended in groove, and the import of lubricant channel is located at the outside of locating piece, and lubricating fluid flows into lubricant channel, finally flowed into
Into the space of gland and bearing.
Further, the bearing is double-row conical bearing.
Further, lip-type packing is provided between the bearing and bevel gear, lip-type packing is sheathed in rotating shaft, lip
Sealing ring is squeezed between box inside and bevel gear.
Further, the lower inwall of the lubricant channel is inclined plane, and the inclined plane is sloped downwardly towards rotating shaft one.
Further, waterproof jacket is provided between the gland and rotating shaft.
Relative to prior art, pinch roll assembling described in the utility model has the advantage that:Structure simplifies, and from
Said in performance, the carrying of the double-row conical bearing of identical internal-and external diameter is bigger than single-row, rigidly to get well, and biserial can
With aligning, single-row cannot;In seal aspect, the sealing means of rotary shaft lip seal are added below bearing, this
Sample just prevents liquid from flowing down to greatest extent.
