880×230有内胎航空轮胎的设计

Design of 880×230 Tube-type Aircraft Tire

介绍880×230有内胎航空轮胎的设计。结构设计:外直径820mm,断面宽192mm,胎圈着合直径465.6mm,胎圈着合宽度151mm,断面水平轴位置(H1/H2)0.968 9,采用3条纵向花纹沟设计,花纹深度4mm,花纹宽度5mm,内胎断面轮廓设计成圆形,内胎壁厚为2.5mm。施工设计:胎体采用12层1400dtex/2V1锦纶66浸胶帘布,稀线层采用2层1400dtex/2V2锦纶66浸胶帘布,缓冲层采用3层1400dtex/3V1锦纶66浸胶帘布;采用压辊包边成型机成型,双模定型硫化机硫化。成品性能试验结果表明,成品轮胎的充气外缘尺寸、静态和动态性能均满足相应设计和标准要求。

The design of 880×230tube-type aircraft tire was described.In the structure design,the following parameters were taken：overall diameter 820 mm,cross-sectional width 192 mm,bead diameter at rim seat 465.6mm,bead width at rim seat 151 mm,maximum width position of crosssection（H1/H2） 0.968 9,with the design of 3longitudinal pattern grooves,pattern depth 4mm,pattern width 5mm,the inner tube with the design of circular section,and inner tube thickness 2.5mm.In the construction design,the following processes were taken：12layers of 1400dtex/2V1 dipped nylon 66 cord for carcass ply,2layers of 1400dtex/2V2 dipped nylon 66 cord for an additional ply in which the cords were arranged in wide spacing,3layers of 1400dtex/3V1 dipped nylon 66 cord for breaker ply;using press rolling and tipping building machine to build tires,and using curing press to cure tires.It was confirmed by the tests of finished tires that,the inflated peripheral dimension,static mechanical properties and dynamic properties met the requirements of the relative design and standard.
