| 中文摘要: |
| 分析具有轮辋保护结构轮胎常见缺陷的产生原因，并提出相应的解决措施。胎体帘布打压方式不合理、胎侧打压方向错误、三角胶高度设计不合理、三角胶打压不实、胎侧尺寸设计不合理、成型鼓宽度偏大、工艺操作不到位等均会导致具有轮辋保护结构的轮胎出现胎体帘布打褶、耐磨胶形状异常等缺陷。通过合理设计三角胶和胎侧尺寸、调整打压方式、严格执行工艺管理和操作规范等措施可以有效减少轮胎缺陷。 |
| 英文摘要: |
| The causes of common defects in tires with rim protection structures were analyzed，and corresponding solutions were put forward.Unreasonable pressing methods of carcass cord fabric，incorrect sidewall pressing direction，unreasonable bead height design，improper bead reverse pressing，unreasonable sidewall size design，excessively large building drum width，and inadequate process operation could all lead to defects such as carcass cord fold and abnormal wear-resistant compound shape in tires with rim protection structures.The defects could effectively reduced through measures such as reasonable design of bead and sidewall dimensions，adjustment of pressing methods，and strict implementation of process management and operating specifications. |
