摘　　要：采用以钢铁为基体高分子自润滑复合材料为衬层制作的传动件，兼有优良的减磨耐磨性能和高的承载能力。研究了组分对复合材料性能的影响，制备了机械和摩擦学性能好的碳纤维增强复合材料，其黏结强度和压缩强度分别达到16-18MPa和85-91MPa，冲击强度达19．67-23．45kJ／m2；与锡青铜ZQSn6—6—3摩擦对比试验表明，复合材料在重载工况下具有更优良的摩擦性能，工作状况稳定，油摩擦因数为0．077，仅为ZQSn6—6—3的59％。试验还发现，轻载启动和在摩擦面开设润滑油槽有助于改善摩擦状况。Transmission parts made of steel backing and lining of polymer self-lubrication composites have excellent anti-friction and wear-resisting performances as well as high burden ability. Effects of the components on the composites performances were studied. A carbon fiber reinforced composites with both good mechanical and tribological properties was established. Its bonding and compress strengths are 16～18 MPa and 85～90 MPa respectively. The impact strengths are 19.67～23. 45 MPa. Comparison experiments show that the composites tribologi- eal properties are better than those of tin bronze ZQSn6-6-3 under heavy duty. The friction condition of the composites is steady,and the friction coefficient under oil is 0. 077, only 59% of ZQSn6-6-3. Experiments also show that starting with light loads and oil grooves on friction surfaces can improve friction condition.
