れている。In the present invention, the sliding member refers to a member that has a surface that slides in low-friction contact with a mating member and supports a load or transmits the load to another member, such as a bearing bush, a sliding plate, a cam, and a member for both wheels. Phenolic resin sliding members using cotton cloth, asbestos, wood flour, etc. as reinforcing base materials have been well known, and have been used for the purpose of improving the mechanical properties of sliding members. It is also well known to use reinforcing substrates such as glass fibers or carbon fibers.
しかしながら、フェノニル樹脂を基体とする摺動部材は
一般には、給油あるいは給水などのP1渭条件下でなけ

軸と摺動した場合、相手材をかじる、言い換えれに相手
材を損傷させるという欠点を生ずるなどである。For example, in order to improve frictional properties, the solid lubricant described above must be blended in a large amount to be effective; In addition, in order to improve the wear resistance, it is possible to increase the surface hardness of the sliding member by blending hard carbon drifted fibers. If it slides on the shaft, it may bite the mating material or, in other words, cause damage to the mating material.
とくに、相手材を損傷させることは摺動部材として糠力
避けなけれはならない。In particular, as a sliding member, it is necessary to avoid damaging the mating material.

The technical problem is to develop a phenolic resin composition for sliding members.
上記技術的課−題を達成するべく本発明の構成、すなわ

ml of phenolic resin for sliding parts, which is mixed with a certain amount of carbon fiber, cotton cloth, thermoplastic synthetic resin, and solid lubricant.
The second composition has a phenolic resin as its base, and contains carbon fiber on the foot side, cotton cloth, thermoplastic synthetic resin, solid hydrant, and lubricating oil for sliding members. It is a phenolic resin composition.

45%, 3 to 10 parts of thermoplastic synthetic resin, 1 part of solid lubricant
-20% lubricating oil, 1 to 5% lubricating oil, and the balance phenolic resin composition for sliding members.
上述した構成において、補強基材としてフェノール樹脂

耐摩耗性を向上させ、また綿布は摺動部材としての機械
的強度を向上させる。In the above structure, the carbon fibers mixed with the phenolic resin as a reinforcing base material do not themselves exhibit any lubricity, but the carbon fibers mixed with the phenolic resin improve mechanical properties, especially surface hardness. The cotton fabric improves the abrasion resistance of the sliding member, and the cotton fabric also improves the mechanical strength of the sliding member.
これら補強基材は摺動部材の使用目的に応じて、その配
合量が決定される。The blending amount of these reinforcing base materials is determined depending on the intended use of the sliding member.
たとえば、摺動部材が水潤渭東件下で使用される場合に
L該摺動部材の膨潤を考慮して、炭素繊維を多目にと夛
、また摺動部材に強度が要求される場合には綿布を多目
にとるなどである。For example, when a sliding member is used under wet conditions, a large amount of carbon fiber is added to take into account the swelling of the sliding member, and when the sliding member is required to have strength. For example, use a large amount of cotton cloth.
上述した水潤滑における摺動部材の膨潤を防止する観点
からは、フェノール樹脂の補強基材に炭素繊維単独を使
用することにょシ達成されるが、炭素繊維はフェノール
樹脂との密着性に劣るため、摺動部材としての機械的強
度が低く、その使用にあたっては低荷重東件下に限られ
るなど、摺動部材の使用範囲が限定される。The above-mentioned prevention of swelling of sliding members during water lubrication can be achieved by using carbon fiber alone as a reinforcing base material for phenolic resin, but carbon fiber has poor adhesion with phenolic resin. However, the mechanical strength of the sliding member is low, and its use is limited to low load conditions, which limits the range of use of the sliding member.
、そこで、本発明では補強基材として炭素繊維に加えて

するものである。Therefore, in the present invention, in addition to carbon fiber, cotton fabric with good adhesion to phenol resin is used as a reinforcing base material in order to improve the mechanical strength of the sliding member without impairing the effect of carbon fiber. Moreover, it can be used even in applications where the usage conditions are severe, such as bearings for rolling rollers (roll neck bushings) for steel manufacturing, where impact loads are applied.
このように、補強基材として綿布を併用することは、水
潤滑における摺動部材の膨潤を防止する観点から毎若干
犠牲と々るが、摺動部材の用途範囲を大幅に拡大する仁
とで補なわれる。。In this way, the use of cotton cloth as a reinforcing base material requires some sacrifice in terms of preventing the sliding member from swelling during water lubrication, but it has the advantage of greatly expanding the range of applications of the sliding member. Compensated. .
第1表はフェノール樹脂に対する補強基材と該補強基材
を充填したフェノール樹脂成形物の機械的性質および水
中における膨潤量を試験した結果である。Table 1 shows the results of testing the mechanical properties and swelling amount in water of reinforcing base materials for phenolic resins and phenol resin moldings filled with the reinforcing base materials.

嚢中の膨pltは水温を60℃の温度に加温し、該温水
中に20日間浸漬したのち、取り出して寸法の変化量か
ら測定したものである。The swelling plt in the first shishikasa was measured by heating the water to 60° C., immersing it in the warm water for 20 days, taking it out, and measuring the amount of change in dimension.

に応じτ、炙緊繊維10〜薗重量−1綿布lO〜45重
量%配合される。Therefore, the blending amount of the reinforcing base material with respect to the phenolic resin can be up to 60% by weight, and within this range, depending on the above-mentioned use, it can be blended with Ru.

繊維の均一分散性かそこなわれ、また成形上の困難性も
生ずるので最適の長さをとることか必要である。The carbon fiber used as the reinforcing base material 1 in the present invention has a large ratio of diameter to fiber length L, that is, L/D (aspect ratio), and has a large mechanical strength (high surface hardness). Although it is possible to obtain a shoulder sliding member, the fibers are too thin.
If the length is too long, it will be difficult to mix with the resin and cotton cloth, the uniform dispersion of the fibers will be impaired, and there will be difficulty in molding, so it is necessary to choose an optimal length.
直径か30ミクロン以下、望ましくは20ミクロン以下
の可及的に細いものでありて、 I4/Dが10以上
であることρ1IFftLいことを本発明者らは実験に
よシ確認した。The present inventors have confirmed through experiments that the diameter is as thin as possible, with a diameter of 30 microns or less, preferably 20 microns or less, and that I4/D is 10 or more.
すなわち、このものは巨視的には粉末であるが、微視的
には繊維状のチンプギーンである。That is, this material is macroscopically powdery, but microscopically it is fibrous chimpgeen.

相手材の摩耗を大きくするばかシで表く、摺動部材とし
ての耐摩耗性をも害するようになる。When the L/D of carbon fiber becomes smaller than 10 υ, the powder shape changes from fiber powder to granular powder.
This increases the wear of the mating material and also impairs the wear resistance of the sliding member.

原料として得られたものか使用される。The carbon fibers used include chemical fibers such as acrylic, rayon, and vinyl fibers, those obtained using other thermosetting synthetic resins as raw materials, or those obtained using lignin, pinch, etc. as raw materials.

布からなる組成物に配合されて、とくに炭素繊維の欠点
を補うとともに摺動部材に自己潤滑性を付与する。The thermoplastic synthetic resin is blended into a composition made of phenolic resin and carbon fiber-woven cotton cloth, and particularly compensates for the drawbacks of carbon fiber and provides self-lubricating properties to sliding members.
すなわち、補強基材としての炭素繊維は摺動部材の機械
的性質および耐摩耗性の向上に寄与することについては
前述したとお夛であるが、その反面摺動部材の摩擦面に
露出して相手材との摩擦において相手材をかじるという
欠点を備えている。In other words, as mentioned above, carbon fiber as a reinforcing base material contributes to improving the mechanical properties and wear resistance of the sliding member, but on the other hand, it is exposed to the friction surface of the sliding member and causes damage to the sliding member. It has the disadvantage of biting the other material when it comes into friction with the material.
この相手材をかじるという性質は相手材ttJ!傷させ

繊維の欠点である相手材をかじるという性質を切土する
ことかできたものである。In the present invention, by blending a thermoplastic synthetic resin and scattering the synthetic resin on the male sliding surface of the sliding member, the above-mentioned drawback of carbon fiber, which has the tendency to bite the mating material, can be overcome. It is something that

摩擦に移行するためである。上述した熱可塑性合成樹脂
の効果は、とくに高荷重条件下において顕著にしめられ
ることを実験によシ確認した。The thermoplastic synthetic resin scattered on the friction surface is partially transferred to the mating surface 11'-F due to friction with the mating material, forming a thermoplastic synthetic resin film on the surface of the mating material, This is because friction occurs through the thermoplastic synthetic resin coating between the mating member, the sliding member, and the cage. It has been experimentally confirmed that the above-mentioned effect of the thermoplastic synthetic resin is particularly noticeable under high load conditions.

摺動部材の摩擦特性をよ勺一層内上させるものである。Since these thermoplastic synthetic resins themselves have self-lubricating properties, they impart self-lubricating properties to sliding members in addition to the above-mentioned effects, and when used in combination with solid lubricants described below, the frictional characteristics of sliding members can be improved. It is something that will make you even more proud.

そして、熱可塑性合成樹脂の配合量は3〜10重量%が
適当である。The above-mentioned thermoplastic synthetic resins, especially polyolefin resins, are compatible with lubricating oils, which will be described later, so they exhibit properties as a retainer that absorbs and retains lubricating oils or adsorbs and retains lubricating oils on friction surfaces. It has the effect of significantly improving properties (low coefficient of friction)1, and the appropriate amount of thermoplastic synthetic resin is 3 to 10% by weight.
熱可塑性合成樹脂は前記炭素繊維と比較してその比重が

になる。Since the thermoplastic synthetic resin has a lower specific gravity than the carbon fibers, a comparatively small amount of the resin will be effective, and a large amount will have a negative effect on the solid lubricant described later.
固体潤滑剤は上記成分に配合され、とくに熱可塑性合成
樹脂と協働して摺動部材に自己潤滑性を付与するもので
ある。The solid lubricant is blended with the above components and works particularly with the thermoplastic synthetic resin to impart self-lubricating properties to the sliding member.

ましい。These solid lubricants are used when the sliding member is attached to the carbon fiber.
Since the Jff surface hardness is square, the lubricating effect is fully exhibited on the friction surface of the sliding member, but it is preferable to select and use it as appropriate depending on the purpose of use of the sliding member.

レン樹脂を選択して使用するなどである。For example, when sliding members are used under water-lubricated conditions, graphite, metal soap, or polytetrafluoroethylene resin, which has particularly good compatibility with water, should be selected, and when used under oil-lubricated conditions. In such cases, molybdenum disulfide, tungsten disulfide, or polytetrafluoroethylene resin may be selected and used.
摩擦特性を向上させんがために固体潤滑剤を多量に配合
することは摺動部材の強度低下をきたす゛ことになるた
め、その配合量はとくに注意を必要とする。If a large amount of solid lubricant is blended in order to improve frictional characteristics, the strength of the sliding member will be reduced, so special care must be taken when determining the amount of solid lubricant to be blended.
固体潤滑剤の配合量は前記熱可塑性合成樹脂の配合量と
のかね合いで決定されるが、本発明では概ね1〜20重
量−の配合量が適当であることを実験によ勺確認した。Although the amount of the solid lubricant to be blended is determined in consideration of the amount of the thermoplastic synthetic resin, it has been experimentally confirmed that a blending amount of approximately 1 to 20% by weight is appropriate in the present invention.

がいかんなく発揮される。When the blending amount of the thermoplastic synthetic resin mentioned above is set at the upper limit, the blending amount of this solid lubricant is set at the lower limit, and conversely, when the blending amount of the thermoplastic synthetic resin is set at the lower limit, this solid lubricant By setting the blending amount to the upper limit, the synergistic effect of both can be fully exhibited.
泊渭油は上記成分組成に配合されて摩擦特性をより一層
