| 介绍53/80R63无内胎全钢巨型工程机械子午线轮胎的设计。结构设计：外直径 3 820 mm，断面宽度
1 295 mm，行驶面宽度 1 182 mm，行驶面弧度高 82 mm，胎圈着合直径 1 588 mm，胎圈着合宽度 914.4 mm，断面水平轴位置（H1/H2） 0.88，胎面采用综合性花纹设计，花纹深度 110 mm，花纹周节数 38，花纹饱和度 75%。施工设计：冠部胶和基部胶采用胶条缠绕工艺成型，1# 和2# 带束层采用7×7×0.25＋0.15HT高强度钢丝帘线，3# 和4# 带束层采用7×（3＋9＋15×0.245）＋0.245HT高强度钢丝帘线，5# 和6# 带束层采用4×6×0.25HE高伸长钢丝帘线，胎体采用7×（3＋9＋15×0.245）＋0.245HT高强度钢丝帘线，胎坯采用六鼓二次法成型机成型，采用蒸锅式硫化机硫化。试验结果表明，成品轮胎的充气外缘尺寸和耐久性能符合设计和国家标准要求。 |

| The design of 53/80R63 tubeless giant all-steel off-the-road radial tire was described.In the structure design，the following parameters were taken：overall diameter 3 820 mm，cross sectional width 1 295 mm，width of running surface 1 182 mm，arc height of running surface 82 mm，bead diameter at rim seat 1 588 mm，bead width at rim seat 914.4 mm，maximum width position of cross–section（H1/H2） 0.88，the tread using a comprehensive pattern design，pattern depth 110 mm，number of pattern pitches 38，block/total ratio 75%.In the construction design，the following processes were taken：adopting rubber strips to wrap the tread craw and base for building，1# and 2# belt using 7×7×0.25＋0.15HT high tenacity steel cord，3# and 4# belt using 7×（3＋9＋15×0.245）＋0.245HT high tenacity steel cord，5# and 6# belt using 4×6×0.25HE high elongation steel cord，using six drum secondary building machine to build green tire，using steaming pot vulcanization press to vulcanizate tire.The test results showed that，the inflated peripheral dimention and durability of the finished tire met the design and national standard requirements. |
