Abstract
The utility model discloses a supporting roll used for a straightening machine. The supporting roll comprises a roll body, a roll core connected to the roll body through a bearing, a thrust ring located at the tail end of the roll body, and an O-type seal ring located between the roll body and the roll core. An annular seal groove is formed in the roll body, the annular seal ring is arranged around the roll core and located between the bearing and the thrust ring, a lip-shaped seal ring is installed in the annular seal groove, and the lip-shaped seal ring is in interference fit with the roll core. The lip-shaped seal ring is longer in service life compared with the O-type seal ring, maintenance frequency is reduced, production efficiency is improved, and sealing effects are good due to the fact that the lip-shaped seal ring is matched with the O-type seal ring in use.
Description
Technical field
The utility model relates to the machinery processing apparatus field, particularly a kind of backing roll for straightener.
Background technology
Straightener is the equipment that shape, bar, tubing, wire rod etc. are aligned.Straightener pushes bar etc. by smoothing roll and makes it change linearity.Two row's smoothing rolls are generally arranged, and quantity does not wait.Two-roll straightening machine is also arranged, rely on the angle variation of two rollers (middle indent, hyperbola roller) that the material of different-diameter is aligned.Main type has gag straightener, balance to roll straightener, footwear roll straightener, rotation recurvation straightener etc.
In the prior art, see also Fig. 1, for the lubricating oil in the backing roll inner bearing 3 that prevents straightener throws away, cause and occur the greasy dirt plate in the product, O RunddichtringO 4 together is set between the body of roll 1 of backing roll and the roller core 2 comes lubricating oil in the sealed bearing 3, but the service life of O RunddichtringO 4 is shorter, causes maintenance times more, influences production efficiency.
Therefore, how to improve the structure of straightener backing roll, can reach long-time steady operation, reduce maintenance times, enhance productivity, become the important technological problems that those skilled in the art need to be resolved hurrily.
The utility model content
In view of this, the utility model provides a kind of backing roll for straightener, so that its steady operation for a long time reduces maintenance times, enhances productivity.
For achieving the above object, the utility model provides following technical scheme:
A kind of backing roll for straightener, comprise the body of roll, by bearing be connected roller core on the described body of roll, at thrust ring and the O RunddichtringO between described roller core and described thrust ring of described body of roll end, have an annular seal groove on the described thrust ring, described annular seal groove is around described roller core setting, in the described annular seal groove lip-type packing is housed, described lip-type packing and described roller core are interference fit.
Preferably, the cross sectional shape of described lip-type packing is U-shaped.
Preferably, described lip-type packing is between described O RunddichtringO and described bearing.
From technique scheme as can be seen, the backing roll that is used for straightener that the utility model provides, comprise the body of roll, by bearing be connected roller core on the body of roll, at the thrust ring of body of roll end and the O RunddichtringO between roller core and thrust ring, have an annular seal groove on the thrust ring, annular seal groove is around the roller core setting, lip-type packing is housed in the annular seal groove, and lip-type packing and roller core are interference fit.Lip-type packing has improved production efficiency than O RunddichtringO service life longly having reduced maintenance times, and lip-type packing and O RunddichtringO be used, and sealing effectiveness is better.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation that is used for the backing roll of straightener in the prior art;
Fig. 2 is the structural representation that is used for the backing roll of straightener among the utility model embodiment.
The specific embodiment
The utility model provides a kind of backing roll for straightener, so that its steady operation for a long time reduces maintenance times, enhances productivity.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 2, Fig. 2 is the structural representation that is used for the backing roll of straightener among the utility model embodiment.
A kind of backing roll for straightener that the utility model provides, comprise the body of roll 1, by bearing 3 be connected roller core 2 on the body of roll 1, at thrust ring 6 and the O RunddichtringO 4 between roller core 2 and thrust ring 6 of the body of roll 1 end, have an annular seal groove on the thrust ring 6, annular seal groove arranges around roller core 2, lip-type packing 5 is housed in the annular seal groove, and lip-type packing 5 is interference fit with roller core 2.
Compared with prior art, the backing roll that is used for straightener that the utility model provides, on the basis of original O RunddichtringO 4, increase lip-type packing 5 and come lubricating oil in the sealed bearing 3, the service life of lip-type packing 5 is long than O RunddichtringO 4, reduced maintenance times, improved production efficiency, lip-type packing 5 and O RunddichtringO 4 are used better effects if.
The cross sectional shape of the lip-type packing 5 that the backing roll that is used for straightener that the utility model embodiment provides adopts is U-shaped, can certainly adopt the lip-type packing 5 with other cross sectional shapes.
Preferably, among the utility model embodiment lip-type packing 5 between O RunddichtringO 4 and bearing 3.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
