Description
Technical field
It the utility model is related to jaw in a kind of mining machinery field and break secret seal structure, it is close that particularly a kind of jaw breaks machine bearing
Seal structure.
Background technology
Jaw breaks machine（Jaw crusher）It is disintegrating apparatus earlier occur, because of its simple structure, firm, reliable operation, dimension
Shield and maintenance easily and production and construction cost it is fewer, therefore, up to now still widely metallurgy, chemical industry, building materials,
The industrial departments such as electric power, traffic, for crush compression strength 147~245MPa various ores and rock it is carse, medium and small
It is broken.Existing jaw breaks arbor system and is substantially using grease lubrication, and its structure is all the warp by the way of the labyrinth seal of end face
Bearing oil starvation often is caused due to forgetting that grease-added or lubricating grease leakage is too fast, causes Bearing Temperature or bearing to embrace
Extremely, bearing can only finally be changed.
The content of the invention
The purpose of this utility model is above mentioned problem be present for existing labyrinth seal, it is proposed that a kind of novel labyrinth is close
The mode of envelope, on the basis of existing end face labyrinth seal mode, increase the structure of axial labyrinth seal.
The purpose of this utility model can be realized by following technical proposal：A kind of new jaw breaks machine bearing sealing structure,
Including main shaft（1）, the main shaft（1）It is sequentially card arc closure from outside to inside（2）, card arc end cap（3）, self-aligning roller bearing
（5）, dust ring（6）, dust-proof seal ring（7）, Bearing outer is bearing block（4）, it is characterised in that the left end card arc closure
（2）With card arc end cap（3）Between retain original end face labyrinth seal, add axial labyrinth seal；The right-hand member dust ring
（6）With dust-proof seal ring（7）Between retain original end face labyrinth seal, add axial labyrinth seal.
In above-mentioned jaw breaks machine bearing sealing structure, card arc end cap（3）And dust ring（6）Except there are 2 labyrinths end face
Outside seal groove, there are two square grooves of A and B from the inside to surface on endoporus；Card arc closure（2）With it is dust-proof close（6）Seal removes
End face has outside 2 labyrinth seal grooves, it is small it is cylindrical on also respectively have a square groove C coordinated with A and B.
In above-mentioned jaw breaks machine bearing sealing structure, lubricating grease enters self-aligning roller bearing（5）, with aligning roller axle
Hold（5）Motion, progressively heat, lubricating grease is also slowly thinning, slowly from self-aligning roller bearing（5）Middle spilling, lubricating grease are left to
Card arc closure（2）And dust-proof seal ring（7）On, most of lubricating grease is because the effect of centrifugal force is outwards splashed, and small part
Lubricating grease enters card arc closure（2）With card arc end cap（2）, dust ring（6）With dust-proof seal ring（7）Between gap in, by
In card arc closure（2）And dust-proof seal ring（7）Centrifugal force caused by rotation, lubricating grease are progressively accumulated in card arc end cap（2）With
Dust ring（6）Two square grooves of A and B in, after being filled with, due to the surface tension of lubricating grease, the profit in two square grooves of A and B
Consistent lubricant is with card arc closure（2）And dust-proof seal ring（7）Rotate and rotate, so as to form twice oil scraper ring, prevent lubricating grease
Leak out, reach the purpose of oil sealing.
In above-mentioned jaw breaks machine bearing sealing structure, work as main shaft（1）Phased out rotation, card arc end cap（2）With it is dust-proof
Circle（6）The lubricating grease of two square grooves of A and B be slowly attached to card arc closure with the reduction of centrifugal force（2）With it is dust-proof close
Seal（7）It is small it is cylindrical on, work as main shaft（1）After stopping operating, card arc end cap（2）And dust ring（6）Two square grooves of A and B
Lubricating grease slowly flow to card arc closure（2）And dust-proof seal ring（7）Square groove C in, as temperature slowly reduces, lubricating grease
Retrogradation, so as to be attached in tri- square grooves of A, B, C, avoid lubricating grease leakage.
In above-mentioned jaw breaks machine bearing sealing structure, the structure that original jaw breaks the labyrinth seal of generator terminal face is also retains,
Lubricating grease is filled out in original two seal grooves during assembling, plays dustproof effect.
Compared with the structure that original jaw breaks the labyrinth seal of generator terminal face, new jaw breaks machine bearing sealing structure and adds axial direction
Labyrinth seal structure, the twice oil scraper ring formed by lubricating grease itself, prevents lubricating oil to leak out, solves profit substantially
The problem of consistent lubricant leaks.This structure is very simple, does not increase part, and square groove need to be only increased on original detail just can be real
It is existing, and only need lathe just to complete, easy to process, cost is extremely low.
