摘　　要：为进一步实现高速机车轻量化的目标,通过试验研究了2024铝合金挤压铸造机车传动空心轴的铸造工艺。经过试验与分析得出,在浇注温度为730℃、模具预热温度为240℃、压力为120 MPa、保压时间为2.5 min的情况下,得到的铸件质量较佳。In order to further achieve the goal of high speed locomotive lightweight, the materials for aluminum alloy 2024 was studied by experiments. The locomotive transmission shaft was achieved by squeeze casting technology of casting process by experiment and analysis. When hollow shaft transmission in the process of squeeze casting pouring temperature is 730 ℃, mould preheating temperature is 240℃, pressure is 120 MPa and holding time is 2.5 min, the better quality casting can be obtained.
