| 中文摘要: |
| 优选V带（B型）骨架材料、包布和底胶挤出口型。结果表明：采用高模量低收缩聚酯钢化棕丝线绳作骨架材料，采用粘合增强型涤棉混纺帆布作外包布，采用高口型挤出底胶，制备的V带粘合性能和耐疲劳性能较好，使用寿命显著延长。 |
| 英文摘要: |
| In this study，the reinforcing skeleton material and wrapping material of the V-belt（type B） and the extrusion die for primer were optimized. The results showed that，when the high modulus low shrinkage tempered polyester cords were used as the skeleton material，polyester-cotton blended canvas with enhanced adhesion property was applied as the wrapping material，and the primer was extruded with high extrusion die，the finished V-belt possessed good adhesion property，good fatigue resistance，and significantly extended service life. |
