【摘要】：为了减轻特装重卡传动轴的重量,同时不降低其强度,对主要零部件进行了重新设计,对零部件毛坯的锻造工艺和机加工工艺进行了重新规划。设计了万向节总成,确定了万向节的规格,通过计算最终确定轴管尺寸为Φ150 mm×7 mm,通过对比相关的性能指标,对花键轴进行了选型,改进了端面齿突缘叉和花键轴毛坯的锻造工艺以及花键轴的机加工工艺,最终实现了特装重卡传动轴总成轻量化设计制造。实践结果表明,在不降低传动轴性能的前提下,通过减小关键零部件毛坯的下料尺寸,提高了材料利用率,传动轴总成减重6.76 kg,减重8.45%,实现了传动轴的轻量化设计。
[Abstract]:In order to reduce the weight of the drive shaft of the special heavy truck without reducing its strength, the main parts were redesigned, and the forging technology and machining technology of the blank of the parts were replanned. The universal joint assembly is designed, and the specification of the universal joint is determined. the size of the shaft tube is 桅 150 mm 脳 7 mm, and the splice shaft is selected by comparing the related performance indexes. The forging technology of end face tooth protruding fork and splice shaft blank and the machining technology of splice shaft are improved. Finally, the lightweight design and manufacture of special heavy truck transmission shaft assembly is realized. The practical results show that, on the premise of not reducing the performance of the transmission shaft, the material utilization ratio is improved by reducing the blanking size of the blank of the key parts, and the weight loss of the transmission shaft assembly is 6.76 kg, and 8.45%. The lightweight design of transmission shaft is realized.
