摘要
针对机车驱动冷却风扇的立式电机在运行中承受较高的冲击振动,通过分析冷却风扇电机整体结构特点,提出了新的轴承结构形式。
Aiming at the relatively high impact vibration exerted on the vertical motor of locomotive cooling fan bearing in the operation, the paper proposes a new bearing structure form through analyzing the overall structure features of cooling fan motor.
