The invention discloses a damping device for an axle box and the axle box, and the damping device comprises an axle box body which is provided with a damping hole; the vibration reduction box is attached to the surface of the side portion, provided with the vibration reduction hole, of the axle box body and surrounds the periphery of the vibration reduction hole, an open hole is formed in the position, corresponding to the vibration reduction hole, of the vibration reduction box, and a cavity is formed in the vibration reduction box; and the damping particles are filled in the cavity. The axle box body is provided with the vibration reduction hole and the vibration reduction box, and the vibration reduction box is arranged near the vibration reduction hole, so that the vibration reduction hole and the vibration reduction box form a superposed vibration reduction effect, and the vibration reduction effect is better. The damping particles are arranged in the cavity of the vibration reduction box, so that in the running process of the railway vehicle comprising the axle box, the damping particles in the cavity of the vibration reduction box can be utilized to increase structural damping, the effect of consuming vibration energy is achieved, the vibration of the axle box can be reduced, particularly, broadband vibration can be restrained, vibration transmission is reduced, and the service life of the axle box is prolonged. Therefore, vibration fatigue of the axle box can be reduced, service life of the axle box is prolonged, and service cycle of the axle box is prolonged.

    本发明公开了一种用于轴箱的减振装置及轴箱,包括:轴箱体,设有减振孔;减振盒,贴合于轴箱体开设有减振孔的侧部的表面,并围设于减振孔的外周部,减振盒对应减振孔的位置设有开孔,减振盒的内部设有腔体;阻尼颗粒,填充于腔体内。轴箱体设有减振孔的同时,设有减振盒,将减振盒设于减振孔附近,使减振孔和减振盒形成叠加减振作用,使减振效果更好。在减振盒的腔体内设置阻尼颗粒,这样,在包含该轴箱的轨道车辆运行过程中,可以利用减振盒腔体内的阻尼颗粒增大结构阻尼,起到对振动能量进行消耗的作用,从而可减少轴箱振动,尤其是有利于抑制宽频振动,减少振动传递,从而可降低轴箱的振动疲劳,提高轴箱的工作寿命,增长轴箱的使用周期。
