| 中文摘要: |
| 汽车发动机同步带在日本、欧洲、美国已在多种车型上广泛使用；我国正处于开发试验阶段，但已有一定数量的国产汽车使用。目前汽车发动机同步带的齿型主要为梯形齿，主体橡胶为氯丁橡胶，骨架线绳为玻璃纤维绳，齿包布为尼龙帆布；今后的发展方向是：齿型为圆弧齿，主体橡胶为氢化丁腈橡胶或氯磺化聚乙烯橡胶，骨架材料为芳纶1414纤维、P84纤维和PBI(聚苯并咪唑)纤维，齿包布为耐磨且抗剪切的新型织物。 |
| 英文摘要: |
| The synchronous belt has been widely appllied to the automotive engine in Japan，Europe and North America.Some development work has been done on the synchronous belt in China and some products are used in China’automotives.In the future，the arc tooth will take place of the trapezoid tooth in the synchronous belt；the HNBR or CSM will replace NBR as the basic polymer；polyaromid 1414，P84 fibre and PBI fibre will be used in stead of glass fibre as reinforcement material；and new wear and shear-resistant textile will be substituted for nylon canvas as tooth wrap. |
