文中介绍的传动带,是由加入短纤维的三元乙丙橡胶制成的。该胶带在高温时弹性模量高,受侧面压力变形小,从而改善了耐磨耗性能。由于掺入短纤维增强,在室温和低温下具有优良的耐屈挠疲劳性能。
The transmission belt introduced in this article is made of EPDM with short fibers. The tape has a high modulus of elasticity at high temperatures and small deformation due to lateral pressure so as to improve abrasion resistance. Due to the incorporation of short fibers, it has excellent flexural fatigue resistance at room and low temperatures.
