Design of 18.4-34 10PR R-2 Agricultural Tire

介绍18.4-34 10PR R-2农业轮胎的设计。结构设计:外直径1 678mm,断面宽450mm,行驶面宽度430mm,行驶面弧度高34mm,胎圈着合直径868mm,胎圈着合宽度406mm,断面水平轴位置(H1/H2)0.50,花纹深度78mm,花纹饱和度20.2%,花纹周节数18。施工设计:胎面采用三方五块结构,胎体采用6层1870dtex/2锦纶6浸胶帘布,并增加2层930dtex/2锦纶6缓冲帘布;采用LCX-4B型成型机成型,立式硫化罐硫化。成品性能试验结果表明,成品轮胎的充气外缘尺寸和物理性能均符合国家标准及相关设计要求。

The design of 18.4-34 10 PR R-2 agricultural tire was described.In the structure design,the following parameters were taken：overall diameter 1 678 mm,cross-sectional width 450 mm,width of running surface 430 mm,height of running surface 34 mm,bead diameter at rim seat 868 mm,bead width at rim seat 406 mm,maximum width position of cross section（H1/H2）0.50,pattern depth 78 mm,block/total ratio 20.2%,and total number of pitches 18.In the construction design,the following processes were taken：three-formula and five-piece extruded tread,6 layers of 1870 dtex/2 dipped nylon 6 cord for carcass ply,and 2 layers of 930 dtex/2 nylon 6 cord for breaker ply;using LCX-4 Btype building machine to build tires,and using autoclave to cure tires.It was confirmed by the tests of finished tires that the inflated peripheral dimension and physical properties met the requirements of national standards and relative design.
