Description
Technical field
The utility model belongs to mine equipment technical field, relates to a kind of sealing arrangement, is specifically related to a kind of preventing side running of belt conveyer carrying roller end seal.
Background technology
At present, the deflection preventing support roller of underground belt conveyor is due to poor working environment, the problems such as stream time is long, the deflection preventing support roller that frequent appearance causes because sealing arrangement damages rotates not smooth, even stuck problem, greatly have impact on the fortune coal efficiency of underground belt conveyor, and bring very large potential safety hazard to the safety in production in colliery.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of preventing side running of belt conveyer carrying roller end seal is provided, it is reasonable in design, and structure is simple, stable and reliable for performance, long service life, applied widely, dismounting is simple, is convenient to safeguard, productive costs is low, is convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: a kind of preventing side running of belt conveyer carrying roller end seal, comprise for the carrying roller of back-up belt machine belt conveyor and the rotating shaft for installing described carrying roller, being provided with the antifriction-bearing box for reducing friction force between described rotating shaft and described carrying roller, it is characterized in that: also comprising the seal ring for preventing lubricating oil from leaking and the back-up ring for preventing described seal ring from getting loose; Described rotating shaft is positioned at outside described antifriction-bearing box and is set with described seal ring and described back-up ring successively, described rotating shaft is positioned at outside described back-up ring and is installed with jump ring, between described jump ring and described back-up ring, be provided with pad.
Above-mentioned preventing side running of belt conveyer carrying roller end seal, is characterized in that: described jump ring is fixedly mounted in described rotating shaft by the draw-in groove being arranged on described roller end.
Above-mentioned preventing side running of belt conveyer carrying roller end seal, is characterized in that: described seal ring is O type rubber seal.
The utility model compared with prior art has the following advantages:
(1) design of this preventing side running of belt conveyer carrying roller end seal is very reasonable, and simple and compact for structure, can effectively prevent coal ash from entering, the lubricating reliability of antifriction-bearing box strengthens greatly.
(2) this preventing side running of belt conveyer carrying roller end seal makes bring up to more than 12 months by former 3 months the service life of carrying roller antifriction-bearing box, and service life increases greatly.
(3) this preventing side running of belt conveyer carrying roller end seal dismounting is very simple, is convenient to safeguard, is not only applicable to the sealing of carrying roller end, and be also applicable to the field that other needs sealing, Applicable scope widely.
(4) a lot of parts of this preventing side running of belt conveyer carrying roller end seal are convenient to produce and buy all very much, and thus its productive costs is very low, is convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.

Detailed description of the invention
A kind of preventing side running of belt conveyer carrying roller end seal as shown in Figure 1, comprise for the carrying roller 5 of back-up belt machine belt conveyor and the rotating shaft 1 for installing described carrying roller 5, being provided with the antifriction-bearing box 7 for reducing friction force between described rotating shaft 1 and described carrying roller 5, also comprising the seal ring 6 for preventing lubricating oil from leaking and the back-up ring 4 for preventing described seal ring 6 from getting loose; Described rotating shaft 1 is positioned at outside described antifriction-bearing box 7 and is set with described seal ring 6 and described back-up ring 4 successively, described rotating shaft 1 is positioned at outside described back-up ring 4 and is installed with jump ring 2, between described jump ring 2 and described back-up ring 4, be provided with pad 3.
In the present embodiment, described jump ring 2 is fixedly mounted in described rotating shaft 1 by the draw-in groove being arranged on described rotating shaft 1 end.
In the present embodiment, described seal ring 6 is O type rubber seal.
The working process of the utility model preventing side running of belt conveyer carrying roller end seal is: first this preventing side running of belt conveyer carrying roller end seal is arranged on control position, carrying roller 5 rotates under the drive of belt feeder belt conveyor, it is inner that seal ring 6 can effectively prevent coal ash from entering antifriction-bearing box 7, seal ring 6 also can effectively prevent the lubricating grease of antifriction-bearing box 7 inside from leaking simultaneously, thus effectively prevents antifriction-bearing box 7 premature failure.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every above embodiment is done according to the utility model technical spirit any simple modification, change and equivalent structure transformation, all still belong in the protection domain of technical solutions of the utility model.
