| 中文摘要: |
| 介绍26.5R25全钢工程机械子午线轮胎的设计。结构设计：外直径 1 738 mm，断面宽 660 mm，行驶面宽度 606 mm，行驶面弧度高 33.68 mm，胎圈着合直径 629.5 mm，胎圈着合宽度 566 mm，断面水平轴位置（H1/H2） 0.83，花纹深度 37 mm，花纹饱和度 63%。施工设计：胎面采用热喂料缠绕成型方式，胎体采用7×7×0.22+0.15HT钢丝帘线，带束工作层采用3+9+15×0.22+0.15钢丝帘线，带束保护层采用3×7×0.20HE钢丝帘线，正六角形钢丝圈采用φ2.0 mm胎圈钢丝，两鼓一次法成型机成型，单模热板硫化机硫化。成品性能试验结果表明，轮胎的充气外缘尺寸、耐久性能和TKPH值均达到设计和相关标准要求。 |

| The design of 26.5R25 earth-mover radial tire was described.In structure design，the following parameters were taken：overall diameter 1 738 mm，cross sectional width 660 mm，width of running surface 606 mm，height of running surface 33.68 mm，bead diameter at rim seat 629.5 mm，bead width at rim seat 566 mm，cross-sectional level ratio（H1/H2） 0.83，pattern depth 37 mm，and block/groove ratio 63%.In construction design，the following processes were taken：using hot-feed winded tread，7×7×0.22+0.15HT steel cord for carcass ply，3+9+15×0.22+0.15 steel cord for belt working ply，3×7×0.20HE steel cord for belt guard ply，φ2.0 mm bead wire for hexagonal bead，and using two-drum one-stage building machine to build tires and single-mold hot press to cure tires.It was confirmed by the test of finished tires that the inflated peripheral dimension，endurance and TKPH value met the requirements in design and related standard. |
