Description
Technical field
The invention belongs to field of work machines, be a kind of sprocket shaft group, particularly composite solid lubrication sprocket shaft group.
Background technology
Coal-winning machine flexible flightconveyor, the sprocket shaft group of scraper-type elevating conveyor, be the crucial portion of coal-mine integrated-mining equipment
Part.Relative technological improvement, is directly connected to efficiency and the benefit of coal mine fully-mechanized mining system.From the 40's of 20th century at English
So far, the leakage of oil of scrapper conveyor sprocket shaft group causes the damage problem of this assembly to the First chain type coal-winning machine that state is born, always
The crux of puzzlement coal-winning machine technological progress, developing rapidly especially with economic society, the social production ability of the energy is continuous
Being pulled up by demand, not the shutting down of plant equipment bearing production important task continuously runs the focus just becoming common concern.
At present, from English, meaning, moral, the scrapper conveyor sprocket shaft group of U.S. import, average life less than 24 months, through dimension
After repairing reuse the life-span also with regard to half a year about, structure is identical with domestic, and price is but more than domestic 8 times；Domestic chain
Though axle set critical component therein mostly uses hophornbeam to agree, the internationally renowned brand bearing such as FAG, SKF, NSK, float close
Seal ring, but its new product is delivered for use, life-span average is about nine months, the average life five after secondary maintenance
About Yue.No matter the sprocket shaft group of import, or domestic sprocket shaft group, be all because floating seal ring therein abrasion,
Lubricate bearing that unreliable, lubricant leakage causes, spline, the related property of gear coupling are destroyed and are caused system-down.Every time
Shut down these parts of replacing and averagely need about 8 hours.Equipment uses unit therefore to shut down and cause production loss, dismounts simultaneously
Spark or electrostatic that the collision of equipment causes may cause serious fire or gas explosion event.The especially sprocket shaft of import
Group, increases the cost of manufacturing enterprise, also consumes too many national capital, it is suppressed that China has technological progress by oneself；Equally, state
The short life producing sprocket shaft group directly contributes the waste of this parts manufacturing recourses, and the leakage of lubricating oil causes the pollution of environment.
Summary of the invention
It is an object of the invention to provide a kind of composite solid lubrication sprocket shaft group, solve leakage of oil that sprocket shaft group exists,
Lubricate that unreliable, floating seal ring rapid wear, the extraordinary abrasion of bearing inner sleeve, bearing cage be damaged, spline wear excess, tooth
The phenomenons such as wheel shaft coupling damage.
The technical scheme is that composite solid lubrication sprocket shaft group, it at least includes floating seal ring and Sealing Method
Orchid, floating seal ring is two identical beckets of geometry, and floating ring is fixing with sealing flange to be connected, and stationary ring laminating is floating
Rotating ring and both relative motioies, is characterized in that: the binding face of floating ring or stationary ring is ring-type hole structure of hiding, and hides in hole
There is kollag.
Composite solid lubrication sprocket shaft group, it also includes bearing, and bearing is made up of inner ring, outer ring, keeper and rolling element,
It is characterized in that: keeper is hole structure of hiding with the contact surface of inner ring and outer ring that there is kollag in hole of hiding.
Described hole size of hiding is Φ 2.5mm*1mm, and the adjacent spacing hiding hole is 5mm.
It is an object of the invention to: on floating seal ring, 1, use ring-type hole structure of hiding, it is ensured that floating seal ring exists
Lubricant compensation free of discontinuities during dynamic friction, the lubricant between rubbing surface when simultaneously also ensure that floating seal ring static friction
Deposit, lubricant, when friction occurs to produce, can produce on a face of friction pair and more for a long time and more firmly be combined
Solid lubricant film.So, block the direct friction between floating seal ring rubbing surface to greatest extent, thus reduce abrasion
Extending the life-span, its sealing function has obtained effective guarantee.
2, on the keeper of bearing, hole structure of hiding is used, it is ensured that there is sufficient composite solid lubricant on rolling element surface
Agent compensates so that it is in the tracks of bearing internal external circle, the kollag of transfer forms solid and reliable composite solid lubricant
Film, thus improve the weight bearing power of sprocket shaft group bearing, decrease abrasion, improve the life-span of bearing.

Detailed description of the invention
Embodiment 1
As it is shown in figure 1, the core sealing member of composite solid lubrication sprocket shaft group includes floating seal ring 1 and sealing flange 4,
Floating seal ring 1 is to be made up of two identical beckets of geometry.One is floating ring 3, and it is fixed on sealing flange 4
On；Another is stationary ring 2, and stationary ring 2 fits together with floating ring 3 and does relative motion, it is achieved sealing effectiveness.
As shown in Fig. 2, the binding face of stationary ring 2 uses ring-type hole 5 structures of hiding, the binding face of floating ring 3
Smooth, hole 5 sizes of hiding are Φ 2.5mm*1mm, and the adjacent spacing hiding hole 5 is 5mm, have solid lubrication in hole 5 of hiding
Agent.
During work, stationary ring 2 and floating ring 3 relative motion, the binding face of stationary ring 2 uses ring-type hole 5 of hiding
Structure, it is ensured that the floating seal ring 1 lubricant when dynamic friction compensation free of discontinuities, also ensure that floating seal ring 1 simultaneously
Lubricant deposit between rubbing surface during static friction, lubricant, can be on a face of friction pair when friction occurs to produce
Produce firm more for a long time and more composite solid lubricant film.So, block floating seal ring rubbing surface to greatest extent
Between direct friction, thus reduce abrasion and extend the life-span, its sealing function has obtained effective guarantee.
Embodiment 2
The present embodiment is essentially identical with embodiment 1 structure, and except for the difference that the binding face of floating ring 3 uses ring-type hole 5 of hiding
Structure, has kollag in hole 5 of hiding, and the binding face of stationary ring 2 is shiny surface.
Any one binding face of two beckets of floating seal ring 1 use ring-type hide hole 5 structures can be
Actual application reaches anticipated effect.
Embodiment 3
As it is shown on figure 3, bearing 6 is the bearing commonly used, it is by inner ring 7, outer ring 8, keeper 9 and rolling element 10 structure
Become, keeper 9 with the contact surface of inner ring 7 and outer ring 8 have employed hole 5 structures of hiding, hole 5 of hiding has solid to moisten
Lubrication prescription.
Hole 5 sizes of hiding are Φ 2.5mm*1mm, and the adjacent spacing hiding hole 5 is 5mm.
During work, the keeper 9 of bearing 6 uses hole 5 structures of hiding, it is ensured that rolling element surface has the most multiple
Conjunction kollag compensates so that it is in the tracks of bearing internal external circle, the kollag of transfer forms solid and reliable answering
Close solid lubricant film, thus improve the weight bearing power of sprocket shaft group bearing, decrease abrasion, improve the life-span of bearing.
Sprocket shaft group is the parts often used in field of work machines, has application, at this in Work machine widely
Do not do particularly explanation.
