摘要
介绍13/80-2016PR反弧形压路机轮胎的设计。结构设计:外直径1028 mm,断面宽304 mm,行驶面宽度322 mm,行驶面弧度高10 mm,胎圈着合直径514 mm,胎圈着合宽度230 mm,断面水平轴位置(H1/H2)0.9922,胎面花纹为光面,胎冠采用反弧形设计。施工设计:胎面采用双复合挤出机挤出,胎体内层(8层)采用1680dtex/2V1锦纶66浸胶帘布,外层(2层)和缓冲层(4层)采用1680dtex/2V2锦纶66浸胶帘布,采用半芯轮式成型机成型、单模定型硫化机硫化。反弧形成品性能试验结果表明,反弧形成品轮胎充气外缘尺寸和物理性能均符合国家标准要求,轮胎胎冠中心部位鼓起成弧形问题得到解决,轮胎的使用性能提高,使用寿命延长。
The design on 13/80-2016PR reverse-arc road roller tire was described.In the structure design,the following parameters were taken:overall diameter 1028 mm,cross-sectional width 304 mm,width of running surface 322 mm,arc height of running surface 10 mm,bead diameter at rim seat 514 mm,bead width at rim seat 230 mm,maximum width position of cross-section(H1/H2)0.9922,smooth tread pattern,and reverse-arc design for the tire crown.In the construction design,the following processes were taken:co-extruded tread,1680dtex/2V1 nylon 66 dipped cord for inner layer(8 layers)of carcass,1680dtex/2V2 nylon 66 dipped cord for outer layer(2 layers)and breaker ply(4 layers)of carcass,using flat-core building machine to build tire,and single-mold curing press to cure tire.The performance test results of the finished tire showed that the inflated peripheral dimension and physical properties met the requirements of national standards,the problem of bulging and arcing in the center of tire crown was solved,the tire performance was improved and service life was prolonged.
