Abstract
The utility model discloses a shaft-sleeve-replaceable press roll device, which comprises a roll shaft, a bearing, shaft sleeves, bearing seats and a transmission device, wherein roll shaft bearings are arranged on the shaft sleeves, every four roll shaft bearings form one group, the shaft sleeves are arranged in a shaft neck position after the roll shaft turning fine grinding, every four shaft sleeves form one group, the bearing seats are arranged in bearing positions arranged at the two ends of the roll shaft and are provided with lubricating oil holes, and the transmission device is arranged at one end of the roll shaft. Through adopting the mode, the shaft-sleeve-replaceable press roll device provided by the utility model has the advantages that the shaft sleeves in the bearing abrasion parts can be replaced at any time, and the service life of the press roll is prolonged.
Description
Technical field
The utility model relates to press-roller device, particularly relates to a kind of replaceable axle sleeve type press-roller device.
Background technology
Milling train is, by the rolling of roll, thicker strip or blank are rolled into thinner strip (paper tinsel), China's steel industry has hot rolling at present, have cold rollingly etc., coloured industry has casting and rolling machine, cold-rolling mill, aluminium foil mill (being divided into again roughing mill, finishing mill), starts again to rise recently hot-rolling mill etc.
The pressure roller of tradition press is all the standard rollers of manufacturer production, in milling train parts, the condition of work of roll is the most complicated, in use, because pressure roller is often subject to great extruding force at rolling process, thereby the wearing and tearing of bearing and axle are seriously accelerated, once pressure roller shaft wearing and tearing, not only can cause the damage of bearing, comprise that whole pressure roller also can not use again, and then cause great waste on producing, also bring unnecessary economic loss to enterprise.
Some enterprises carry out the pressure roller of wearing and tearing to reuse after pressure roller reparation, but in use procedure, find that the pressure roller of repairing is difficult to meet normal rolling work, finally still can not normally use.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of replaceable axle sleeve type press-roller device, the axle journal of the standard rollers dress bearing portion of manufacturer production can be carried out to turning processing, axle is worked into the size needing, then axle sleeve is arranged on roll shaft, then bearing is installed on above axle sleeve, in press work, if roller bearing pressurized or other reasons cause bearing and axle sleeve wearing and tearing, axle sleeve can be changed, load onto new axle sleeve, continue to use.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of replaceable axle sleeve type press-roller device is provided, comprise: roll shaft, bearing, axle sleeve, bearing block and transmission device, described roll shaft bearing is arranged on axle sleeve, described roll shaft bearing is tetrad, described axle sleeve is arranged on roll shaft turning fine grinding diameter of axle position later, described axle sleeve is tetrad, described bearing block is arranged on the bearing portion at roll shaft two ends, described bearing block is provided with oilhole, and described transmission device is arranged on one end of roll shaft.
In preferred embodiment of the utility model, described roll shaft axle sleeve installation position carries out refining after turning, and the mounting means of axle sleeve and axle is interference fit.
In preferred embodiment of the utility model, described axle sleeve is carburizing steel.
In preferred embodiment of the utility model, described axle sleeve is that the mode of expanding with heat and contract with cold is arranged on the axle journal position of roll shaft through turning.
The beneficial effects of the utility model are: the axle sleeve that the utility model weares and teares by replacing, thus avoid the replacing of whole pressure roller, greatly save production cost, reduce the maintenance cost of enterprise aspect equipment.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of a kind of replaceable axle sleeve type press-roller device one preferred embodiment of the utility model.
In accompanying drawing, the mark of each parts is as follows: 1, roll shaft; 2, axle sleeve; 3, bearing; 4, bearing block; 5, transmission device.
Detailed description of the invention
To the technical scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment provides following technical scheme.
In one embodiment, a kind of replaceable axle sleeve type press-roller device, comprising: roll shaft 1, axle sleeve 2, bearing 3, bearing block 4, transmission device 5, described axle sleeve 2 is arranged on the roll shaft 1 of crossing through cutting fine grinding, described bearing 3 is arranged on above axle sleeve 2, and described bearing 3 is that described bearing 3 is using axle sleeve 2 external diameters as rolling surface without inner ring RNA69 series bearing, described bearing block 4 is arranged on above bearing 3, and described transmission device 5 is arranged on one end of roll shaft 1.
Be different from prior art, in one embodiment, the bearing stopper position of described roll shaft 1 is that the internal diameter size of the size after processing and axle sleeve 2 is interference fit by the milling train special roller process turning fine grinding of manufacturer production, described axle sleeve 2 is tetrad, is arranged in order and is arranged on roll shaft 1.
Be different from prior art, in one embodiment, described bearing 3 is 4 one group, is installed on above axle sleeve 2.
Be different from prior art, in one embodiment, described axle sleeve 2 is carburizing steel, and carburizing steel is to have high wearability and hardness, and described axle sleeve 2 is that the mode of expanding with heat and contract with cold is installed on the axle of bearing stopper position.
Be different from prior art, in one embodiment, described bearing block 4 is arranged on above bearing 3, and bearing block is with oilhole, the oiling channel as bearing at operation process.
Be different from prior art, in one embodiment, described pressure roller bears the extruding of backing roll and intermediate calender rolls in rotation process, and described pressure roller is working roll, and described pressure roller is with transmission device 5.
The axle sleeve that the utility model weares and teares by replacing, thus the replacing of whole pressure roller avoided, greatly save production cost, reduce the maintenance cost of enterprise aspect equipment.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
