Novel vibration-damping tooth entering mechanism for mountain toothed rail
The invention relates to the technical field of rack rail trains, in particular to a novel vibration-damping mountain rack rail tooth entering mechanism which comprises a rack steel rail fixed to a rail sleeper beam and two common steel rails, a transition rail is arranged at the starting end of the rack steel rail and comprises an adjusting section and a meshing section, and the adjusting section comprises a rail body and a plurality of roller wheel teeth. Each roller gear tooth comprises a base part and a roller part, the roller parts are rotatably connected with the base parts, and rotating shafts of the roller parts are perpendicular to the extension direction of the rack steel rails. According to the novel vibration-buffering tooth entering mechanism for the mountain toothed rail, the transition rail is arranged at the starting end of the rack steel rail, when a train enters the transition rail from a common rail in the running state, if a gear cannot be well meshed with the transition rail, gear teeth make contact with the roller gear, so that the roller part rolls, and vibration is relieved; therefore, the gear teeth can quickly slide into the tooth grooves to be meshed, structural damage to the gear and the rack steel rail caused by poor meshing is reduced, and the service life of the gear and the rack steel rail is prolonged.
本发明涉及齿轨列车技术领域，特别是涉及一种新型缓振山地齿轨入齿机构，包括固定于轨道枕梁的齿条钢轨和两条普通钢轨，齿条钢轨的起始端设置有过渡轨道，过渡轨道包括调整段和啮合段，调整段包括轨体和若干滚筒轮齿，滚筒轮齿包括基座部和滚筒部，滚筒部与基座部之间为可旋转的连接，滚筒部的旋转轴与齿条钢轨的延伸方向相互垂直。本发明的新型缓振山地齿轨入齿机构，齿条钢轨的起始端设置了过渡轨道，列车在运行的状态下由普通路轨进入到过渡轨道时，若齿轮无法与过渡轨道良好啮合，轮齿与滚筒齿轮接触使其滚筒部产生滚动，进而轮齿可以快速滑入到齿槽中啮合，降低了啮合不良造成的齿轮和齿条钢轨的结构损伤，提高了齿轮和齿条钢轨的使用寿命。
