摘要
介绍12.00-20 20PR工程机械轮胎的设计。结构设计:外直径1 156mm,断面宽274mm,行驶面宽度246.5mm,行驶面弧度高21.5mm,胎圈着合直径509mm,胎圈着合宽度216mm,断面水平轴位置(H1/H2)0.875,采用越野花纹,花纹深度22.5mm,花纹饱和度63.3%,花纹周节数28。施工设计:胎面由胎面胶、胎肩胶和胎侧胶组成,缓冲层采用2层930dtex/2V3锦纶6浸胶帘布,胎体采用14层1400dtex/3锦纶6浸胶帘布(8V1+6V2),钢丝圈采用Φ1.0mm的回火胎圈钢丝,采用LCX-3型成型机成型、B型硫化机硫化。成品性能试验结果表明,轮胎的外缘尺寸和物理性能符合相应设计和国家标准要求。
The design of 12.00-20 20 PR off-the-road tire was described.In the structure design,the following parameters were taken:overall diameter 1 156 mm,cross-sectional width 274 mm,width of running surface 246.5 mm,height of running surface 21.5 mm,bead diameter at rim seat 509 mm,bead width at rim seat 216 mm,maximum width position of cross-section(H1/H2) 0.875,cross-country tread pattern,pattern depth 22.5 mm,block/total ratio 63.3%,and total number of pitches 28.In the construction design,the tread was composed of tread compound,shoulder compound and sidewall compound.2 layers of 930 d tex/2V3 dipped nylon 6 cord were used in breaker ply,14 layers of 1400dtex/3 dipped nylon 6 cord were for carcass ply(8V1+6V2),and Φ1.0 mm copper-plated tempered bead wire was applied in the tire bead.The tire was built using LCX-3 building machine and cured using type B press.It was confirmed by the tests of the finished tire that the peripheral dimension and physical properties met the requirements of design and national standard.
