| 介绍11－38 12PR KT676拖拉机驱动轮轮胎的设计。结构设计：外直径 1 530 mm，断面宽度 290 mm，行驶面宽度 285 mm，行驶面弧度高 30 mm，胎圈着合直径 970 mm，胎圈着合宽度 254 mm，断面水平轴位置（H1/H2）0.666 7，花纹类型 人字形花纹，花纹深度 32.5 mm，花纹饱和度 29.85%，花纹周节数 28。施工设计：胎面采用两方四块结构，缓冲胶片采用天然橡胶/顺丁橡胶并用胶，胎体采用6层加密1400dtex/2V2锦纶6帘布，胎体帘布裁断角度为34.5°；轮胎成型采用半芯轮式成型机，硫化采用蒸汽式硫化机。成品轮胎的充气外缘尺寸和物理性能符合国家标准要求。 |
| 英文摘要: |
| The design of 11－38 12PR KT676 tractor driving wheel tire was presented. In the structure design，the parameters were as follows：outer diameter 1 530 mm，cross-section width 290 mm，width of running face 285 mm，arc height of running face 30 mm，bead diameter at rim seat 970 mm，bead width at rim seat 254 mm，maximum width position of cross-section（H1/H2） 0. 666 7，herringbone pattern for tire tread，pattern depth 32. 5 mm，pattern saturation 29. 85%，and number of pattern pitch 28. In the construction design，two-formula and four-piece construction was used for the tread，natural rubber/butadiene rubber blend was selected for the breaker strip，the carcass was composed by six layers of densified 1400dtex/2V2 Nylon 6 cord，and the cutting angle of the carcass cord was 34. 5°. The tire was formed on flatcore building machine and cured on steamer vulcanizing machine. The inflated peripheral size and physical properties of the finished tire met the requirements of national standards. |
