Therefore, roll is the primary deformable instrument of milling train, is also consumable part therein simultaneously, and abrasion reaches after to a certain degree, it is necessary to shuts down and changes.
Utility model content
In view of this, this utility model provides a kind of roller case, it is possible to extend the filmatic bearing life-span, reduces roll mandrel abrasion, thus improving roller case service life.
This utility model provides a kind of milling train applying above-mentioned roller case.
For achieving the above object, this utility model provides following technical scheme:
A kind of roller case, roll mandrel is supported in roller box body by the filmatic bearing being installed in eccentric bushing, and the oil film section that described roll mandrel coordinates with described filmatic bearing is taper, and this oil film section is its miner diameter end near one end of described roll mandrel end.
A kind of milling train, including main box and the roller case being disposed thereon, is provided with input mechanism and drive mechanism in described main box, described roller case is above-mentioned roller case.
Preferably, described roller case is removably mounted on described main box.
Can be seen that from above-mentioned technical scheme, the roller case that this utility model provides, its roll mandrel is the conical surface with the filmatic bearing place of cooperation, it is beneficial to when roll mandrel is by roll-force and gear radial force, there is deflection deformation, still having certain reliable oil film thickness between roll mandrel and filmatic bearing, thus improving the filmatic bearing life-span, reduce roll mandrel abrasion, and then extend roller case service life. This utility model additionally provides a kind of milling train applying above-mentioned roller case, it is possible to extend maintenance period, thus improving yield.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Roll mandrel that Fig. 1 provides for this utility model embodiment and the structural representation that filmatic bearing coordinates.
Wherein, 1 is roll mandrel, and 2 is filmatic bearing, and 3 is oil film.
Detailed description of the invention
The utility model discloses a kind of milling train and roller case thereof, it is possible to extend the filmatic bearing life-span, reduce roll mandrel abrasion, thus improving roller case service life.
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only this utility model one oil film section embodiment, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, roll mandrel that this Fig. 1 provides for this utility model embodiment and the structural representation that filmatic bearing coordinates.
The roller case that this utility model embodiment provides, roll mandrel 1 is supported in roller box body by the filmatic bearing 2 being installed in eccentric bushing, bear the radial force of roll-force and gear, being installed on the axial force of the axial force when thrust bearing of roll mandrel 1 end bears rolling and gear, collars is installed on roll mandrel 1 by tapered sleeve; Its core improvement is in that, the oil film section that roll mandrel 1 coordinates with filmatic bearing 2 is taper, and this oil film section is its miner diameter end near one end of roll mandrel 1 end. It is understood that roll mandrel 1 two ends are provided with filmatic bearing 2, its structure is referred to shown in Fig. 1; For the roll mandrel 1 oil film section in left side, it is its miner diameter end near the one end of roll mandrel 1 end (now should refer to roll mandrel 1 left end), is structure left small and right large; For the roll mandrel 1 oil film section on right side, it is its miner diameter end near the one end of roll mandrel 1 end (now should refer to roll mandrel 1 right-hand member). It is structure left large and right small.
Can be seen that from above-mentioned technical scheme, the roller case that this utility model embodiment provides, its roll mandrel 1 is the conical surface with filmatic bearing 2 place of cooperation, it is beneficial to when roll mandrel 1 is by roll-force and gear radial force, there is deflection deformation (its mode is as shown in Figure 1), still having certain reliable oil film 3 (now for conical ring form) thickness between roll mandrel 1 and filmatic bearing 2, thus improving filmatic bearing 2 life-span, reduce roll mandrel 1 to wear and tear, and then extend roller case service life.
This utility model additionally provides a kind of milling train, including main box and the roller case being disposed thereon, is provided with input mechanism and drive mechanism in this main box, and power is finally driven roll mandrel 1 to rotate by input mechanism through drive mechanism; Its core improvement is in that, roller case is above-mentioned roller case. This programme applies the milling train of above-mentioned roller case, it is possible to extend maintenance period, reduces machine stop times, thus improving yield.
In order to optimize above-mentioned technical scheme further, roller case is removably mounted on main box. Roller case is by the dowel hole on panel and rolling mill main casing Fast Installation location, and namely the gear on roll mandrel engages transmission power with the gear of main box intermediate solid drive shaft. Modular roller case is removably mounted on main box by the mode of bolt or screw, and has the Quick locating structure adopting alignment pin, it is possible to installation and removal roller case easily, thus realizing quick-replaceable roll, improves work efficiency. On the other hand, it is possible to after modular roller case is pulled down, then roll in it being replaced and safeguards, recycling thus continuing to participate in replacing realization, properly functioning without influence on milling train of period.
In sum, this utility model embodiment provides a kind of roller case, roller case panel and main box are bolted, roll mandrel is supported in roller box body by the filmatic bearing being installed in eccentric bushing, bear the radial force of roll-force and gear, being installed on the axial force of the axial force when thrust bearing of roll mandrel end bears rolling and gear, collars is installed on roll mandrel by tapered sleeve. Described roll mandrel is the conical surface with the filmatic bearing place of cooperation, it is beneficial to when roll mandrel is by roll-force and gear radial force, there is deflection deformation, certain reliable oil film thickness is still had between roll mandrel and filmatic bearing, thus improving the filmatic bearing life-span, reduce roll mandrel abrasion, improve roller case service life. This utility model embodiment additionally provides a kind of milling train applying above-mentioned roller case, it is possible to extend maintenance period, thus improving yield.
In this specification, each embodiment adopts the mode gone forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar oil film section mutually referring to.
