| 中文摘要: |
| 介绍20.5R25★★E-3全钢工程机械子午线轮胎的设计。结构设计：外直径1480 mm，断面宽510 mm，行驶面宽455 mm，行驶面弧度高25 mm，胎圈着合直径629 mm，胎圈着合宽度440 mm，断面水平轴位置（H1/H2）0.8581，花纹深度29 mm。施工设计：胎体帘线采用3+9+15×0.22+0.15HT钢丝帘线，1 #～3 #带束层为3+9+15×0.22+0.15HT钢丝帘线，4#带束层为3×7×0.22HE钢丝帘线，钢丝圈采用直径2.0 mm的六角形钢丝；成型采用两鼓式一次法成型机，硫化采用液压蒸锅式自动硫化机。成品轮胎充气尺寸达到设计要求，耐久性能好。 |
| 英文摘要: |
| The design of 20.5R25 ★★ E-3 all-steel radial OTR tire was described. In the structural design： overall diameter 1480 mm， cross sectional width 510 mm， width of running surface 455 mm， height of running surface 25 mm， bead diameter at rim seat 629 mm， bead width at rim seat 440 mm， maximum width position of cross section (H1/H2) 0.8581， and pattern depth 29 mm. In the construction design： 3+9+15×0.22+0.15 HT steel cord for carcass ply， 3+9+15×0.22+0.15 HT steel cord for the 1# to 3# belt ply， 3×7×0.22HE steel cord for the 4# belt ply， hexagonal steel wire with diameter of 2.0 mm for the bead； using a two drum single stage radialtire building machine to build tires， and automatic hydraulic steam curing machine to cure tires. The inflated peripheral dimension of the finished tire met the design requirements and the endurance performance was good. |
