| 中文摘要: |
| 介绍51×14. 00－23 50PR矿用工程机械轮胎的设计。结构设计：外直径 1 282 mm，断面宽度 390 mm，行驶面宽度 312 mm，行驶面弧度高 6 mm，胎圈着合直径 579 mm，胎圈着合宽度 280 mm，断面水平轴位置（H1/H2）0. 793 3，花纹类型 混合花纹，花纹周节数 26，花纹饱和度 24. 22%。施工设计：胎面采用贴合/缠绕法成型，胎体采用18层高强度1870dtex/2锦纶66帘布，缓冲层采用两层1400dtex/2V3锦纶66帘布，胎圈采用三钢圈结构；成型采用胶囊反包成型机，硫化采用B型硫化机。成品轮胎充气外缘尺寸和物理性能分别达到设计和企业标准要求。 |
| 英文摘要: |
| The design of 51×14.00－23 50PR mining OTR tire was described. In the structure design， overall diameter was 1 282 mm，cross-sectional width was 390 mm，width of running surface 312 mm，arc height of running surface was 6 mm，bead diameter at rim seat was 579 mm，bead width at rim seat was 280 mm，maximium width position of cross-section（H1/H2） was 0.793 3，mixed tread pattern was used，number of the pattern pitah was 26，and block/total ratio was 24. 22%. In the struction design，tread was molded by laminating/winding process，18 layers of high strength 1870dtex/2 nylon 66 cord were applied in the carcass ply，2 layers of 1400dtex/2V3 nylon 66 cord were applied in the breaker ply，and three-ring structure was used for bead. The tire was built using turn-up bladder building machine and cured using type-B press. The inflated peripheral dimension and physical properties of the finished tires met the requirement of design and enterprise’s standard respectively. |
