Abstract
The invention discloses a support roller of a straightening machine. The support roller comprises a roller body, a roller core, a thrust ring and an O-shaped sealing ring, wherein the roller core is connected with the roller body through a bearing, the thrust ring is arranged at the tail end of the roller body, the O-shaped sealing ring is arranged between the roller body and the roller core, the roller body is provided with an annular sealing slot, the annular sealing slot is arranged in a way of surrounding the roller core and between the bearing and the thrust ring, and a lip-shaped sealing ring is arranged in the annular sealing slot and is subject to interference fit with the roller core. Since the service life of the lip-shaped sealing ring is longer than the service life of the O-shaped sealing ring, the maintenance frequency can be reduced, and the production efficiency can be improved. Moreover, since the lip-shaped sealing ring is used with the O-shaped sealing ring in a matching way, better sealing effects can be achieved.
Description
Technical field
The present invention relates to the machinery processing apparatus field, particularly a kind of straightener back up roll.
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 Types 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, affects production efficiency.
Therefore, how to improve the structure of straightener back up roll, steady operation reduces maintenance times for a long time, enhances productivity, and becomes the important technological problems that those skilled in the art need to be resolved hurrily.
Summary of the invention
In view of this, the invention provides a kind of straightener back up roll, so that its long-time steady operation reduces maintenance times, enhance productivity.
For achieving the above object, the invention provides following technical scheme:
A kind of straightener back up roll, comprise the body of roll, by bearing be connected to 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.
Can find out from technique scheme, straightener back up roll provided by the invention, comprise the body of roll, by bearing be connected to 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 in conjunction with, and sealing effectiveness is better.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of straightener back up roll in the prior art;
Fig. 2 is the structural representation of straightener back up roll in the embodiment of the invention.
The specific embodiment
The invention provides a kind of straightener back up roll, so that its long-time steady operation reduces maintenance times, enhance productivity.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
See also Fig. 2, Fig. 2 is the structural representation of straightener back up roll in the embodiment of the invention.
A kind of straightener back up roll provided by the invention, comprise the body of roll 1, by bearing 3 be connected to 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, straightener back up roll provided by the invention, 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 in conjunction with better effects if.
The cross sectional shape of the lip-type packing 5 of adopting in the straightener back up roll that the embodiment of the invention provides is U-shaped, can certainly adopt the lip-type packing 5 with other cross sectional shapes.
Preferably, in the embodiment of the invention 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 present invention.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from the spirit or scope of the present invention, in other embodiments realization.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
