1300×480航空内胎的设计

Design on 1300×480 Tube of Aircraft Tire

介绍1300×480航空内胎的设计。结构设计:外直径1 100 mm,内直径485 mm,断面周长1 060 mm,气门嘴距内胎中心线距离55 mm。施工设计:里口增强织物采用1层1400dtex/2V1锦纶66浸胶帘布,胎体橡胶厚度为3mm,半成品胎筒上厚为2. 8mm,下厚为8. 5mm,平叠宽度为442mm,长度为1700mm,胎筒接头采用人工操作,采用内胎自动硫化机硫化。成品内胎试验结果表明,内胎的质量、厚度和物理性能均满足相应标准要求。

The design on 1300×480 tube of aircraft tire was described. In the structure design,the following parameters were taken:outer diameter 1 100 mm,inner diameter 485 mm,circumference of cross section 1 060 mm,and distance between the valve nozzle and the center line of the inner tube 55 mm. In the construction design,the following processes were taken:the inner reinforced fabric was made of 1 layer of 1400 dtex/2 V1 nylon 66 dipped cord was used as reinforcement,the thickness of matrix rubber was 3 mm,the upper thickness of semi-finished tire was 2. 8 mm,the lower thickness was 8. 5 mm,the width of lamination was 442 mm,the length was 1 700 mm,and the tire joint was manually assembled and vulcanized by automatic inner tube vulcanizing machine. The test results of the finished tube showed that the quality,thickness and physical properties of the tube met the requirements of corresponding standards.
