Belleville spring damping fastener for rail transit steel rail
The invention discloses a belleville spring damping fastener for a rail transit steel rail, which comprises a lower bottom plate, a belleville spring group, an upper top plate, an insulating limiting block and a gauge adjusting block, and is characterized in that the lower bottom plate comprises side plates with holes, and the side plates with the holes are formed at two ends of the lower bottom plate and protrude upwards; the upper top plate is arranged on the lower bottom plate, protruding blocks which are in central symmetry are formed on the upper surfaces of the two ends of the upper top plate, the insulating limiting block and the gauge adjusting block are arranged between the protruding blocks of the upper top plate and the side plate with the hole of the lower bottom plate, and a protrusion on the insulating limiting block penetrates through a through hole in the gauge adjusting block and is inserted into a hole in the side plate with the hole. Therefore, the transverse and longitudinal movement of the upper top plate relative to the lower bottom plate is limited; the belleville spring set is arranged between the lower bottom plate and the upper top plate, a plurality of limiting bosses are formed on the lower surface of the upper top plate, and belleville springs of the belleville spring set are clamped on the corresponding limiting bosses and used for providing elastic support for a steel rail arranged between two protruding blocks on the upper top plate, so that vibration is reduced.
本发明公开了一种轨道交通钢轨用碟形弹簧减振扣件，包括：下底板、碟形弹簧组、上顶板、绝缘限位块及轨距调整块，其中，下底板包括在两端形成的向上突起的带孔侧板；上顶板设置在下底板之上，并且在上顶板的两端的上表面上形成有呈中心对称的凸块，绝缘限位块以及轨距调整块设置在上顶板的凸块与下底板的带孔侧板之间，绝缘限位块上的凸起穿过轨距调整块中的通孔并插入带孔侧板的孔中，由此限制上顶板相对于下底板的横向和纵向的移动；碟形弹簧组设置在下底板与上顶板之间，并且在上顶板的下表面上形成有多个限位凸台，碟形弹簧组的各碟形弹簧卡在对应的限位凸台上，用于为设置在上顶板上两凸块之间的钢轨提供弹性支撑，由此减少振动。
