| 中文摘要: |
| 介绍矿用钢丝缓冲层12.00-20 20PR工程机械轮胎的设计。结构设计：采用原有矿用斜交轮胎模具设计，外直径 1 144.5 mm,断面宽 264 mm，行驶面宽度 228 mm,行驶面弧度高 20 mm,胎圈着合直径 510 mm,胎圈着合宽度 216 mm,断面水平轴位置(H1/H2) 0.927 3，采用以横向花纹为主的混合花纹，花纹饱和度 63.80%，花纹深度 30 mm，花纹周节数 43。施工设计：原有矿用斜交轮胎胎面、胎体和胎圈等的施工设计不变，仅将多层锦纶缓冲层改为2层钢丝缓冲层，且钢丝缓冲层端点均用包边胶包住，同时增加钢丝带束层斜裁设备，采用3B型胶囊反包成型机成型、B型双模定型硫化机硫化。成品轮胎性能试验结果表明，轮胎的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。 |

| The design of 12.00-20 20PR mine off-the-road tire with steel breaker ply was described.In the structure design,the mold design of mine bias tire was used and the following parameters were taken:overall diameter 1 144.5 mm,cross-sectional width 264 mm,width of running surface 228 mm,arc height of running surface 20 mm,bead diameter at rim seat 510 mm,bead width at rim seat 216 mm,maximum width position of cross-section(H1/H2) 0.927 3,mixed tread patterns mainly composed of transverse pattern，block/total ratio 63.80%，pattern depth 30 mm,pattern circular pitch 43.In the construction design,the designs of tread,carcass and bead of original tire were kept unchanged,2 layers of steel breaker ply were used to replace multilayer nylon breaker,and at the same time the ends of steel breaker ply were wrapped by rubber compound.The steel breaker ply was processed on slanting cutting machine,and the tires were built by using 3B bladder turn-up building machine and cured on B-type press.It was confirmed by the test of finished tires that，the inflated peripheral dimension and physical properties met the requirements in the design and national standard. |
