芳纶线绳三元乙丙橡胶多楔带性能研究

Properties of EPDM V-ribbed Belts with Aramid Cords

研究芳纶线绳三元乙丙橡胶(EPDM)汽车多楔带的性能,并与聚酯线绳EPDM汽车多楔带进行对比。结果表明:芳纶线绳EPDM多楔带具有高强度、高模量、低伸长的特点,其传动功率大,应力衰减小,疲劳寿命长,是现代汽车前端辅助传动及带式混合动力汽车传动较为理想的传动带。

The properties of EPDM V-ribbed belts with aramid cords were investigated,and compared with those of EPDM V-ribbed belts with polyester cords. The results showed that the aramid cords reinforced EPDM V-ribbed belts possessed higher strength and modulus and lower elongation. The transmission power of the EPDM V-ribbed belts with aramid cords was stronger,the-stress-decay was slower,and the fatigue life was extended. The aramid cords reinforced EPDM V-ribbed belts was an ideal belt to be used in front end of the auxiliary drive（ FEAD） and belt-driven integrated started generator（ B-ISG） for modern automobiles.
