The invention relates to the field of variable gauge of railway vehicles, and provides a variable gauge wheelset axle box assembling method and an assembling tool. The variable gauge wheelset axle boxassembling method comprises the following steps of assembling a locking spring guide post and a locking spring cover plate; placing a locking spring into an upper counter bore of a locking pin; inserting the locking spring guide post into the locking spring; compressing downwards from the upper end of the locking spring cover plate by using a compressing tool until the locking spring cover plateis tightly adhered to an axle box; releasing the compressing tool after locking pieces at diagonal positions of the locking spring cover plate are mounted and pre-tightened at least; and applying torque to fasten all locking pieces after all locking pieces are pre-tightened. According to the variable gauge wheelset axle box assembling method and the assembling tool, the assembling of a variable gauge wheelset axle box and the locking springs can be realized; the assembling method is simple, and does not have damage to assembled parts; a pre-pressing process is simple, convenient and quick; andthe assembling requirement on forming of a new structural variable gauge wheelset axle box is met.
本发明涉及轨道车辆变轨距领域,提供变轨距轮对轴箱组装方法及组装工装,包括步骤:组装锁紧弹簧导柱与锁紧弹簧盖板;将锁紧弹簧放入锁紧销的上部沉孔,将锁紧弹簧导柱插入锁紧弹簧中;使用压缩工装从锁紧弹簧盖板上端向下压缩,直至锁紧弹簧盖板与轴箱体贴紧;至少安装并预紧所述锁紧弹簧盖板对角位置的锁紧件后释放所述压缩工装;预紧所有锁紧件后施加扭矩将所有锁紧件紧固。本发明可实现变轨距轮对轴箱及锁紧弹簧的组装,该组装方法简单,对组装部件无损伤,预压过程简捷快速,满足变轨距轮对新结构轴箱组成的组装需求。
