本発明は無潤滑で使用する合成樹脂を母材とし
た軸受材料に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bearing material whose base material is synthetic resin and which is used without lubrication.
従来より、いわゆる無潤滑軸受材料としては、
ポリアミド、ポリアセタール、ポリテトラフルオ
ロエチレンなど多くの合成樹脂又はこれらの合成
樹脂にある種の充填材を混入させたものが知られ

上させる目的で、合成樹脂材料に硬質の補強用繊
維（例えばガラス繊維）と固定潤滑剤（例えば二
硫化モリブデン）を充填する場合が多い。 Traditionally, so-called non-lubricated bearing materials include:
Many synthetic resins, such as polyamide, polyacetal, and polytetrafluoroethylene, or these synthetic resins mixed with certain fillers are known. Generally, in order to improve the rigidity and wear resistance of bearing materials, synthetic resin materials are often filled with hard reinforcing fibers (eg, glass fibers) and fixed lubricants (eg, molybdenum disulfide).
しかし、ガラス繊維を充填した軸受材料にあつ

あつても有機質の充填材であるため、軸受材料の
表面硬さが不足し、相手部材の表面アラサが粗い
場合には、軸受材料が摩耗するなど、耐摩耗性が
低いという欠点が残つている。 However, bearing materials filled with glass fiber tend to damage the mating member, and particularly when the mating member is soft such as an aluminum alloy, there is a marked tendency to wear out. Therefore, in recent years, instead of inorganic fillers such as glass fibers, materials filled with synthetic resin powder or fibers that are harder than the base material have been developed and used. However, since this material is an organic filler, if the surface hardness of the bearing material is insufficient and the surface roughness of the mating member is rough, the bearing material may wear out, resulting in poor wear resistance. Shortcomings remain.
本発明は前記欠点を解決した無潤滑軸受材料を
提供することにある。 The object of the present invention is to provide a lubricant-free bearing material that solves the above-mentioned drawbacks.
本発明はポリアミド樹脂を主成分とし、これ

さなどの必要な機械的性質を有するものである。 The main component of the present invention is polyamide resin, which has a fiber diameter of 0.2 to 0.5 μm and an average fiber length of 10 to 10 μm.
Potassium titanate fiber 15-25% by weight which is 20μm
This is a non-lubricant bearing material filled with 5 to 10% by weight of polytetrafluoroethylene resin and 0.2 to 0.4% by weight of carbon.It can support soft mating parts such as aluminum alloy without lubrication, and prevents wear of the bearing material itself. The material is small, does not damage the mating member, and has the necessary mechanical properties such as surface hardness.

状の軸受材料に成形する。 The present invention is produced in the following manner. i.e. polyamide 66 with potassium titanate fiber 15-25
Weight%, polytetrafluoroethylene resin 5-10
% by weight, and 0.2 to 0.4% by weight of carbon as a filler, and the total filling amount of potassium titanate fiber and polytetrafluoroethylene resin is 20 to 35% by weight.
Then, pellets for injection molding are made using a kneading extruder, and this molded pellet is molded into a bearing material of a desired shape.
上記の混合割合は次の理由から決まるものであ

できない。また、チタン酸カリウム繊維の充填量

20重量％以下では、各充填材の効果が必ずしも十
分な範囲のものでなく、材料質のためには不十分
な量であり、一方、前記合計が35重量％以上では
母材に対しての充填材の量が過多となり、軸受材
料として必要な強度、例えば靭性が得られない。 The above mixing ratio is determined for the following reasons. If the potassium titanate fiber is less than 15% by weight, it will not have sufficient dimensional stability necessary as a bearing material, and if it is more than 25% by weight, the degree of damage to the mating member will be large. On the other hand, in polytetrafluoroethylene resin, if it is less than 5% by weight, it is not effective as a friction reducing material, and if it is more than 10% by weight, it cannot have sufficient strength as a bearing material. In addition, the total amount of potassium titanate fiber and polytetrafluoroethylene is
If the amount is less than 20% by weight, the effect of each filler will not necessarily be in a sufficient range and the amount is insufficient for the quality of the material. On the other hand, if the total is more than 35% by weight, the effect of each filler is The amount of filler is too large, and the strength required as a bearing material, such as toughness, cannot be obtained.

結果、本発明の無潤滑軸受材料は各混合材の相乗
効果により、無潤滑で、相手部材を損傷せず、耐
摩耗性の高いものである。 In the bearing material of the present invention, the potassium titanate fiber used as a filler has a fiber diameter of 0.2 to 0.5 μm, an average fiber length of 10 to 20 μm, and a glass fiber diameter of 10 to 20 μm.
The average fiber length of 10 μm is much smaller than that of 100 to 500 μm, and the hardness of potassium titanate fiber is 4 on the Mohs scale, which is about half the hardness of glass fiber. The base material is densely reinforced, and the polytetrafluoroethylene resin powder, which is another filler, is difficult to detach.As a result, the lubricant-free bearing material of the present invention is lubricant-free due to the synergistic effect of each mixed material. It does not damage the mating member and has high wear resistance.
