摘要
介绍地下矿铰接式卡车用18.00R25 E3全钢工程机械子午线轮胎的设计。结构设计:外直径1602 mm,断面宽490 mm,行驶面宽度430 mm,行驶面弧度高20 mm,胎圈着合直径630 mm,胎圈着合宽度330.2 mm,断面水平轴位置(H_(1/)H_(2))0.84,胎面花纹采用胎冠中间全饱和、胎肩羊角形花纹设计,花纹深度30 mm,花纹周节数32,花纹饱和度86.7%。施工设计:胎面胶采用抗切割胶料配方,基部胶采用低生热胶料配方;采用4层带束层结构,其中1^(#)和2^(#)带束层采用7×7×0.22+0.15HT钢丝帘线,3^(#)和4#带束层采用4×6×0.25HE钢丝帘线,胎体采用7×7×0.25+0.15HT钢丝帘线;采用一次法成型机成型,采用单模蒸锅式硫化机硫化。成品轮胎性能试验结果表明,轮胎的充气外缘尺寸、静负荷性能和耐久性能均达到相应设计和国家标准要求。
The design of 18.00R25 E3 all-steel off-the-road radial tires for articulated trucks in underground mining was introduced.In the structure design,the following parameters were taken:overall diameter 1602 mm,cross-section width 490 mm,width of running surface 430 mm,arc height of running surface 20 mm,bead diameter at rim seat 630 mm,bead width at rim seat 330.2 mm,maximum width position of cross section(H_(1)/H_(2))0.84,the tread pattern was designed with full saturation in the middle of the crown and horn pattern on the shoulder,pattern depth 30 mm,number of pattern pitches 32,and block/total ratio 86.7%.In the construction design,the following processes were taken:using the cutting resistant compound formula for tread and using the low heat build-up compound formula for base,4-layer structure for the belt,7×7×0.22+0.15HT steel cord for 1^(#)and 2^(#)belt,4×6×0.25HE steel cord for 3^(#)and 4^(#)belt,7×7×0.25+0.15HT steel cord for the carcass,using one-stage building machine to build tires and single-mode steamer type curing press to cure tires.The test results of the finished tire showed that the inflated peripheral dimension,static load performance and durability of the tire met the requirements of the corresponding design and national standards.
