Abstract
Oil-free self lubrication sliding bearing is the new parts that a new generation's substitution has oil-lubricated bearing, the series of products of SF 1 of our company's production, there is multiple formulations, adapts to different working conditions and uses.Low friction coefficient is kept to lift the compression strength of bearing, the present invention studies by various material prescriptions, it was found that with hexagonal boron nitride, can be with polyphenyl fat and polyimides together, it is filled in polytetrafluoroethylmaterial material formula, by test data analyzer, the compression strength of material is significantly improved, forms new oil-free self lubrication material for sliding bearing.A kind of new oil-free self lubrication sliding bearing for belonging to sliding bearing field of this new material disclosure of the invention.The hexagonal boron nitride that application is 2 40% mixes with polytetrafluoroethylene (PTFE) and other high polymer materials such as polyphenyl fat and polyimides, the oil-free self lubrication material for sliding bearing significantly improved as compression strength, the self-lubricating bearing of high withstand voltage is fabricated to after technological forming, it is characterized in keeping original friction factor in the case where carrying pressure improves, has the function that more preferable self-lubricating and wear-resisting.
Description
Technical field
The present invention relates to a kind of field for belonging to sliding bearing and field of compound material.
Background technology
With the raising of plant equipment requirement, the performance requirement of component of machine is by more and more higher.The gate of the quality monitoring of parts
Key depends on material, technique and process equipment.Good material can improve equipment carrying pressure, improve anti-wear performance, improve and make
With temperature, adaptation runs at high speed, moved back and forth, therefore, either rolling bearing or in general sliding bearing or nothing
The self-lubricating bearing of oil lubrication, all it be unable to do without the research of material.
The self-lubricating bearing of our company's professional production oil-free lubrication, wherein, filled polytetrafluoroethylene+copper powder layer+steel plate
3-layer composite material, bearing are our matured products.For many years for automobile industry, die industry, automation industry and other
The lifting of machinery product performance contributes.Currently, there is the workshop of professional production material in our company, to set up formulating small
Group, it is therefore an objective to go out to be more suitable for the material of era change demand for oilless bearing investigation of materials, oneself is made for made in China 2015
A contribution.
Self-lubricating material technology is using polytetrafluoroethylene (PTFE) as material of main part, present each enterprise all oneself research formulas, but a lot
It is mimicker's formula, adjustment matches, and few people study the development and application of new material.Patent of the present invention is self-lubricating green wood
A kind of breakthrough lifting of material.
Polytetrafluoroethylene (PTFE) is self-lubricating material, there is relatively low friction factor, and the self-lubricating property under common operating mode is excellent.
But the friction factor of polytetrafluoroethylene (PTFE) based self-lubricating material can increase in the case of pressure is increased, ultimately result in entirely ineffective.
Its boost performance makes moderate progress after the solid fraction lubricants such as polytetrafluoroethylene (PTFE) based self-lubricating material addition molybdenum disulfide (MoS2), but not
The needs of more high-mechanic can be met.In addition, the proportion of molybdenum disulfide is the 230% of polytetrafluoroethylene (PTFE), material compares polytetrafluoro again in itself
Ethene is expensive a lot, causes the cost of the polytetrafluoroethylene (PTFE) based self lubricated composite material added with molybdenum disulfide higher.
The content of the invention
It is an object of the present invention to provide a kind of friction factor is low, wear extent is small, high capacity, advantage of lower cost it is comprehensive
New oil-free self lubrication sliding bearing and composite that can be excellent.It is characterized in that hexagonal boron nitride material is applied, can same polyphenyl
Fat and polyimides together, for filled polytetrafluoroethylene material, or substitution molybdenum disulfide, reach more preferable self-lubricating effect.
Hexagonal boron nitride belongs to one kind of ceramic material, belongs to nonmetallic, uses in the product, can meet new environmental protection
It is required that.Hexagonal boron nitride powder can be purchased commercially, be characterized in the solid fraction self-lubricating agent with stronger compression strength,
It can be combined simultaneously with other high polymer materials, the composite prepared with hexagonal boron nitride, by friction-wear test,
In the case of carrying pressure continuous improvement, its friction factor can ensure the level in balance, meet the use of high-mechanic occasion.
Light as polytetrafluoroethylene (PTFE) due to the proportion very little of hexagonal boron nitride, material is again cheaper than molybdenum disulfide in itself,
So material cost is many compared to also being reduced with molybdenum disulfide.
Embodiment
It is a kind of with boron nitride and polyphenyl fat and polyimides come the self-lubricating bearing composite of heightening material compression strength,
