目前,我国绝大部分货车仍采用滑动轴承,在线路和车辆状态尚未改变、列车速度日趋提高的情况下,列车通过曲率较大的线路时,车辆轮对的轴领承受的横向力增大,促使轴领的磨耗加剧。为了适应轴领焊修任务增大的需要,研制了一台双头二氧化碳气体保护自动堆焊轴领的设备。该堆焊机经过一年多时间的生产实践,表 At present, the vast majority of trucks in our country still use plain bearings. When the status of the line and the vehicle has not changed and the train speed is increasing, the horizontal force on the shaft collar of the wheelset increases when the train passes the route with large curvature. Promote shaft wear. In order to meet the needs of the axis welding repair tasks, developed a double-headed carbon dioxide gas protection automatic welding shaft assembly equipment. The surfacing machine after more than a year of production practice, the table
