摘　　要：探讨采用一次法成型的全钢载重子午线轮胎胎坯胎圈内径偏大的解决措施。钢丝圈底部增添胶片对胎坯胎圈内径有明显影响,胎圈宽度也增大,不能解决成品轮胎胎圈质量问题;成型机机头宽度调整对胎坯胎圈内径影响不大,对解决成品轮胎胎圈质量问题也无效;成型鼓撑块直径与胶囊厚度配合调整,可有效降低成品轮胎胎圈质量发生率。In this study, the methods to solve the problem that the oversized inner diameter of the bead of green truck and bus radial （TBR） tire formed using a single-stage building process were investigated. One approach was to add rubber sheet under the base of the bead, which showed significant influence on the inner diameter of green tire. However, the bead width increased. Another approach was to adjust the width of the forming head, which was found to have little effect on the inner diameter of green tire. These two approaches couldn＇ t solve the quality issue of the finished tire bead. It was found that adjustment and good matching of the diameter of supporting block and the capsule thickness could effectively solve the problem and reduce the quality issue of the finished tire.
