摘要
针对320 t鱼雷型混铁车在使用中暴露出的车钩变形,缓冲器损坏,心盘螺栓剪断,心盘、轮缘润滑不良与环境污染等问题进行了研究与改进。提出采用13号大摆角车钩、ST型缓冲器,心盘、轮缘润滑采用干式润滑剂等方案,运用效果良好。
The research and improvement are made on such problems exposed in operation of the 320 t torpedo type mixed iron cars as the coupler deform,damage of draft gears,kerf of center plate bolts,bad lubrication of center plate and wheel flange,and environment pollution.It is put forward to apply such schemes as the No.13 coupler with big swing angle,ST draft gears, and dry type lubricant for center plates and wheel flange.The result of operation is good.
