Abstract
The nylon self-lubricating bearing material of machine manufacturing usefulness is to add the high purity graphite of 50-160% and an amount of molybdenum disulfide, tungsten disulfide, carbon fiber in nylon base, makes through processes such as batch mixing, roller refining, moulding, immersion oil, softening processing.This bearing material has self lubricity, good thermal conductivity, heat resistance, wear resistance and higher compression is arranged and impact strength.
Description
A kind ofly being used for machine-made bearing material, is to be base material with nylon, adds an amount of solid lubricant graphite, molybdenum disulfide, tungsten disulfide and reinforcing material carbon fiber, makes through processes such as batch mixing, moulding, processing.
Bearing material during machine is made, along with the development of chemical industry, the metal bearing material is replaced by nonmetallic material, and especially macromolecular material is widely used in bearing part with its distinctive performance.With nylon is that base material is manufactured bearing shell, as far back as the sixties research is just arranged, and adopts aborning, but because nylon guide is hot relatively poor, thereby can only under the lower situation of running speed, use.For improving the thermal conductivity and the lubricity of nylon bearing material, can in nylon, add solid lubricant molybdenum disulfide, graphite etc.Molybdenum disulfide or graphite as interpolation 20% in nylon can make friction factor reduce half.Adding graphite not only can improve lubricity but also can improve thermal conductivity.Bearing material manufacture method is in the past added quantity of graphite and is no more than 40%(weight at most in nylon), then be difficult to moulding as increasing again, its compressive strength and impact strength are all lower after the moulding, do not have use value.Though adding the nylon bearing material thermal conductivity of 40% graphite improves, but compare with a large amount graphite material, it is bigger that thermal conductivity differs, on-stream seize, it is serious to grind axle, only be useful under 20 meters/minute following conditions of linear velocity and use, this bearing material mating plate serious wear is so application area is restricted.Though high purity graphite bearing material thermal conductivity and lubricity are higher, compressive strength and impact strength are all lower, only are applicable to the condition use that load is less.
Oil-containing nylon graphite bearing material of the present invention, overcome the shortcoming of above-mentioned bearing material, not only thermal conductivity, wear resistance improve a lot than nylon bearing material but also have higher withstand voltage and impact strength, can various conditions below 100 meters/minute use in 120 ℃ of operating temperatures and linear velocity, and need not refuel more than 18 months.
Bearing material of the present invention is to be base material with nylon, adds 50～160%(weight) high purity graphite, and handle through immersion oil, this bearing material consists of:
Nylon 100 weight portions (down together) high purity graphite 50～160
Carbon fiber 5-15 molybdenum disulfide 0-5
Tungsten disulfide 0-5 lubricant oil 5-10
Base material nylon of the present invention can arbitrarily be selected a kind of in nylon 6, nylon 66, NYLON610, the nylon 1010 or several for use and use.The molecular weight ranges of nylon is with 20,000～26, and 000, granularity 300 orders are advisable.Graphite is the main material that adds, and is used for improving thermal conductivity, moisture-proof, wear-resisting and self lubricity.The performance impact of the product confrontation bearing material of graphite is bigger, and for well, granularity should be advisable more than 400～500 orders with the high purity graphite of content more than 99%.The interpolation carbon fiber can obviously improve the withstand voltage and impact strength of bearing material.Add molybdenum disulfide or tungsten disulfide and can improve lubricity, can select one or both also usefulness for use, its purity is with 99%, and granularity 400～500 orders are advisable.Adding lubricant oil is the key of self lubricity.Lubricant oil can be selected mineral oil or organic silicone oil for use.Mineral oil; all can as 15# machine oil, 20# machine oil; mineral oil is because poor heat resistance; be suitable for using under environment or the temperature condition below 60 ℃; the organic silicone oil better heat stability; can be used for the condition of temperature rise more than 60 ℃ and use, silicone oil can be selected commercially available methyl-silicone oil ethyl silicon oil and other type silicon oil for use.
Self-lubricating bearing material of the present invention is according to suitable prescription is selected in the requirement of bearing part, makes through batch mixing, mixing, moulding, immersion oil, process such as softening.
Moulding can with the material of mixing under 260 ℃ at in-mold molding, also mixing material can be cut into the molding and forming of 3-7mm particle.
The adding of lubricant oil can be got part lubricant oil and be sneaked into when batch mixing, remaining lubricant oil immerses when immersion oil.Softening processing is that the bearing member behind the immersion oil is handled in hot water, to improve elasticity.
Embodiment:
By prescription nylon is mixed with lubricant oil, add remaining solid lubricant and carbon fiber mixing again, mixing on roller refining machine, be cut into the 3-7mm particle after mixing, inject 40～50 ℃ of moulds of mould temperature down at 225～260 ℃, the full pressure 5 seconds, finalized the design 30～40 seconds, to be cooled to depanning below 80 ℃.Then at 140 ℃ ± 5 ℃ following immersion oil to established amount, handled 2 hours through boiling water is softening again, promptly get bearing completed products spare.
Can make satisfactory bearing member by above-mentioned prescription and technological method.
In above-mentioned prescription, has higher use value 3～No. 6.Below be that No. 3, No. 5 prescriptions are made into 1515 weaving machines lead along by hand bearing shell and contrast test data contrast.
