摺動部材がアルミ合金製の軸の回転により削り取られる
という問題点が指摘されている。As automobiles, copiers, etc. become lighter, stainless steel is being replaced by aluminum alloys for crankshafts and shafts. Stainless steel shafts have smooth surfaces, so there were no problems with conventional sliding parts made of lubricant-containing engineering resins, but since aluminum alloys have been substituted, the surfaces of these alloys are rough. It has been pointed out that the sliding member made of resin is scraped off by the rotation of the shaft made of aluminum alloy.

粉を分散させて機械的強度を向上させることも知られて
いるが、相手材のアルミニウム合金の摩耗が激しくなる
という問題がある。It is known to improve mechanical strength by dispersing glass fiber or glass powder to prevent sliding members from being scraped off, but this has the problem of increasing wear on the aluminum alloy of the mating material.

しかし、グリースは補充に手間がかかるし、周辺が汚れ

相手金属が接することができる摩耗の小さな摺動部材の
出現が望まれている。However, grease is time-consuming to replenish and has the drawback of staining the surrounding area, so there is a desire for a sliding member with less wear that allows direct contact between the sliding member and the mating metal without the use of grease.

提供することにある。In the present invention, when a polyamide such as general-purpose nylon 66 or nylon 6.66 copolymer is used as an engineering plastic, the mating material is not only stainless steel but also zinc alloy, aluminum alloy, etc., which have a rough surface finish. It is an object of the present invention to provide a polyamide resin composition which can provide a sliding member with extremely low wear even without intervening grease between the two.

However, it is possible to use mica and talc together with the above calcium silicate. Further, polyaramid fibers and carbon fibers may be blended in a proportion of 10% by weight or less (composition for sliding members).

耐摩耗性が十分でない。The polyamide content in the sliding member composition is 42 to 90% by weight, preferably 55 to 70% by weight. If the weight is less than 42 weight, the strength of the sliding member is weak. If it exceeds 90% by weight, the wear resistance will not be sufficient.

．． 5 to 8% by weight, preferably 1 to 5 weight%. 0.
If it is less than 5% by weight, the lubricity will not be sufficient and the sliding member will be scraped off by the aluminum alloy of the other party. If it exceeds 8% by weight, extrusion or injection molding will be difficult.
摺動部材組成物中のけい酸カルシウム含有量は９．５〜
５０重量％、好ましくは２０〜４５重量％である。The calcium silicate content in the sliding member composition is 9.5 to

シウムが浮き出し、表面平滑性が悪くなる。If it is less than 24.5% by weight, the sliding member tends to warp, and the wear resistance against the metal of the mating material is insufficient. Furthermore, the strength of the sliding members (bearings, gears, etc.) is low, making it impractical. If it exceeds 50% by weight, calcium silicate will stand out on the surface of the sliding member, resulting in poor surface smoothness.
