Description
Technical field
The present invention is a kind of gyratory crusher dissection type sealing structure being related in mine, building equipment technical field.
Background technology
Gyratory crusher is a kind of crushing plant, is mainly used for being crushed the rock and ore of various hardness.With mine, build
The enlargement of material aggregate company, it is higher and higher to the output demand of crusher unit hour, therefore crusher is gradually sent out to enlargement
Exhibition, structure is more complicated, volume is huger, and operating condition, load-up condition are more severe, to the stability of crusher with can
Higher is required by property.Main shaft is one of various most important parts of large and medium-sized gyratory crusher, does complicated swing campaign,
Therefore conventional sealing structure can not be applied, and sealing difficulty is larger, can not ensure the cleanliness factor of lubricating oil.It designs in the prior art
The main shaft seal that the large and medium-sized gyratory crusher of manufacture uses has a disadvantage that：It is unreliable to seal, and dust can not be prevented to enter
In lubricating oil, the service life of lubricating oil and crusher major part is seriously reduced；It can not prevent in crusher lubricating cavity
Outside lubricating oil splash to crusher, the loss of lubricating oil is caused；Sealing element at main shaft replace it is cumbersome, need by
Crusher is torn open greatly, and the operating rate of crusher is influenced, and causes unnecessary loss.Crusher load-up condition badly makes this increasingly
A little disadvantages become increasingly conspicuous.Therefore, the new class that a kind of gyratory crusher dissection type sealing structure is always anxious to be resolved is developed
Topic.
Invention content
The purpose of the present invention is to provide a kind of gyratory crusher dissection type sealing structure, which solves the prior art and deposits
The problem of, improve the reliability of sealing, prevent outside lubricating oil splash to crusher, and can be under the premise of not tearing equipment open very much
Replace sealing.
The object of the present invention is achieved like this：A kind of gyratory crusher dissection type sealing structure, including the first sealing ring,
Second sealing ring, structure glue, the first axis pin, main shaft, the second axis pin overlap the first sealing ring, in the groove of main shaft
The groove of two sealing rings, main shaft is located on the interface of crusher lubricating cavity B and external environment A, the first sealing ring, the second sealing
The notch C of circle is staggered 90 ° and arranges, the first sealing ring, the second sealing ring notch C at use structure glue connection, the first sealing ring,
First axis pin, the second axis pin are set at the notch C of the second sealing ring；
A kind of operation principle of gyratory crusher dissection type sealing structure and using operating method it is, the first sealing ring,
Second sealing ring relative superposition is mounted on the groove on main shaft, which is located at crusher lubricating cavity B and crusher is non-lubricated
On the interface of chamber A, which is located at the lower part of original main shaft seal D, is the supplement to original main shaft seal D；First is close
Notch C is arranged in envelope, the second sealing ring, and using the material with certain pliability, 100% high-purity Teflon is, it can be achieved that in main shaft
Under the premise of not removing, in installation to the groove of main shaft, maintenance cost is reduced；In order to improve intensity, the first sealing ring, second
Sealing ring overlapping is placed, with structure glue by bonding at cutting mouth C and in the first axis pin of incision, the second bearing pin chain after installation
Connect, the first sealing ring, the second sealing ring outer circle contact with crusher dustproof sealing cover E, the first sealing ring, the second sealing ring
Internal upper and lower surface is contacted with spindle channel, forms sealing surface, dust is prevented to enter；When carrying pressure in the lubricating cavity B of lower part
When lubricating oil splashes vertically upward, stopped by sealing ring, return to lubricating cavity, prevents lubricating oil splash non-lubricated to crusher
Chamber A.
The present invention is characterized by its structure and working principle and uses operating method.
A kind of gyratory crusher dissection type sealing structure compared with prior art, has that sealing reliability is high, a little repair,
The advantages that preventing lubricating oil spluttering, will be widely used in mine, building equipment technical field.
