地铁车辆用构架翻转机用于转向架构架的分解与组装。在轮对及其他附件拆除后,将构架放置于翻转机上,利用翻转机的夹持机构、旋转机构,将构架进行180°(正反方向合计360°)翻转,便于转向架构架的检修、拆卸或组装零部件。文章阐述了构架翻转机升降机构丝杠螺纹和减速电机的设计计算方法,并对丝杠强度和螺母强度进行校核。同时对构架翻转机的结构部分和电气部分的设计进行了说明。
Subway vehicles with frame reversing machine for the bogie frame decomposition and assembly. After the wheelsets and other attachments are disassembled, the frame is placed on the reversing machine, and the frame is rotated by 180 ° (total 360 ° in both directions) by means of the clamping mechanism and rotating mechanism of the reversing machine, so as to facilitate the overhaul and disassembly of the frame of the bogie Or assemble parts. The paper expounds the design and calculation method of screw thread and gear motor of lifting mechanism of frame turnover machine and verifies the screw strength and nut strength. At the same time, the design of the structural part and the electrical part of the frame reversing machine are described.
