全钢子午线轮胎胎侧径向单条实鼓的原因分析及解决措施

分析全钢子午线轮胎胎侧径向单条实鼓的原因并提出相应的解决措施。径向单条实鼓分为强光下呈现胎侧部位凹陷和凸起两种形式,产生的原因主要有对应位置胎体帘线密、胎体帘线稀开、胎侧/内衬层复合件接头大或裂开等。通过采取调整缝合器压合轮间隙、碟簧片间距,规范压合底辊形式,打磨压合轮及规范胎侧/内衬层接头大小等措施,有效解决了全钢子午线轮胎胎侧径向单条实鼓的问题。

Shot lining of magnesium alloy with hard powders

To improve the surface properties,lining of magnesium alloys with hard powders by shot peening was carried out in order. The hard powders were tried to bond to the workpiece surface due to the collision of many shots.In order to fix the hard powders to the surface of the workpiece,the powders were set on an uneven surface.To easily facilitate fixing of powders,lining of the workpiece with the powder sandwiched between two aluminum foil sheets was also attempted.In this experiment,a centrifugal shot peening machine with an electrical heater was employed.The workpieces were magnesium alloys AZ31B and AZ91D,and the hard powders were commercial cemented carbide,alumina,and zirconia.The joinability of hard powders near the lined surface was observed by a optical microscope.The wear resistance was also evaluated by a wear test.The hard powders were successfully bonded to the surface of workpieces by the shot lining process.The results show that the present method is effective in wear resistance of the magnesium alloys.
