摘　　要：分析了某型电力机车轮对压装过程,通过核查相关尺寸链和设备情况,找到了辅助压盖这个使轮对压装距离不足的根本原因,对压装设备进行了相应改进,重新设计制作了2个辅助压盖,间接实现了车轴长度的自然补偿,指出该项改进措施提高了生产效率,保证轮对压装符合要求。This paper analyzes the wheel press mounting process of a certain type of electric locomotive, finds out the root cause of insufficient wheel pressing distance by checking the relevant dimension chain and equipment. By improving the corresponding press mounting equipment and redesigning two auxiliary gland, the natural compensation of axle length is realized. Results show that the improvement measures improves the production efficiency and ensures that the wheel press mounting meets the requirements.
