航空子午线轮胎成型工艺技术研究

Study on Building Process and Technology of Aviation Radial Tire

介绍航空子午线轮胎成型工艺及技术装备,研究成型工艺控制要点。航空子午线轮胎二次法一体化成型工艺技术采用T+2型成型机布局法,一段成型工艺包括一段内衬层贴合、一段布筒(反包层)贴合、一段布筒(正包层)贴合和型胶贴合;二段成型工艺包括带束层螺旋形缠绕、波纹保护层贴合、胎面贴合和定型鼓定型。航空子午线轮胎技术装备发展方向为专业化和差异化。

The building process and technical equipment of aviation radial tire were introduced,and the key points of building process control were investigated.The typical building technology of aviation radial tire was a two-stage process using a T+2 building machine and layout method.The first stage building process included first stage inner liner lamination,first stage cord cylinder(turn-up plies)lamination,first stage cord cylinder(turn-in plies)lamination and die rubber lamination,and the second stage included belt spiral winding,corrugated protective layer lamination,tread lamination and drum shaping.The development directions of aviation radial tire technology and equipment are specialization and differentiation.
