| 中文摘要: |
| 介绍14.00-25 36PR工程机械斜交轮胎的设计。结构设计：外直径 1 387 mm，断面宽 373 mm，行驶面宽度 295 mm，行驶面弧度高 30 mm，胎圈着合直径 633 mm，胎圈着合宽度 252 mm，断面水平轴位置(H1/H2) 0.837 4，花纹深度 27 mm，花纹饱和度 69.9%，花纹周节数 28，采用横向块状花纹设计。施工设计：胎面采用三方五块结构；胎体采用14层1400dtex/3V1和2层1400dtex/3V2锦纶66浸胶帘布，缓冲层采用4层1400dtex/2V3锦纶66浸胶帘布；采用胶囊反包成型机成型，胶囊硫化机硫化。成品轮胎试验结果表明，轮胎充气外缘尺寸和物理性能均符合相应设计和国家标准要求。 |
| 英文摘要: |
| The design of 14.00-25 36PR off-the-road bias tire was described.In structure design，the following parameters were taken：overall diameter1 387 mm，cross-sectional width 373 mm，width of running surface 295 mm，height of running surface 30 mm，bead diameter at rim seat 633 mm，bead width at rim seat 252 mm，maximum width position of cross section (H1/H2) 0.837 4，pattern depth 27 mm，block/groove ratio 69.9%，pattern circular pitch 28，with the design of transverse pattern block.In construction design，the following processes were taken：three formula and five piece extruded tread，14 layers of 1400dtex/3V1 and 2 layers of 1400dtex/3V2 dipped nylon 66 cord for carcass ply，4 layers of 1400dtex/2V3 dipped nylon 66 cord for breaker ply；using bladder turn-up building machine to build tires，and using bladder curing press to cure tires.It was confirmed by the tests of finished tires that the inflated peripheral dimension and physical properties met the requirements of corresponding design and national standard. |
