Gear rack rail system of mountain rack rail railway
The invention relates to a gear rack rail system of a mountain rack rail railway. The gear rack rail system comprises sleepers, rubber damping base plates, fastener assemblies, steel rails, wheels, wheel axles, rack rails and pin shaft gear assemblies. The pin shaft gear assembly is installed on the wheel shaft, is of a spherical hinge structure and is meshed with the rack rail in a self-adaptive mode. The device has the advantages that 1, the pin shaft gear adopts a spherical hinge structure to realize self-adaptive meshing of the pin shaft gear and the toothed rail, so that reliable force transmission is ensured; secondly, the pin shaft gear can ensure that a plurality of pin shaft rollers are always meshed with the toothed rail, so that better derailing prevention and wear resistance are achieved, and an inter-tooth back clearance is not generated in the positive and negative directions; the longitudinal bearing capacity of the toothed rail is large, and the requirement for longitudinal force generated by driving when the train runs on the ramp is met; a roller of the pin shaft gear assembly smoothly rolls on the tooth surface of the toothed rail, tooth knocking sound cannot be generated, and vibration is reduced; and fifthly, the problems that the transverse resistance of a traditional strip-shaped sleeper in a small-curve-radius section is low and the longitudinal stability of a ballast bed in a large-gradient section is insufficient are solved.
本发明涉及一种山地齿轨铁路的齿轮齿轨系统，包括轨枕、橡胶减振垫板、扣件组件、钢轨、车轮、车轮轴、齿轨和销轴齿轮组件。销轴齿轮组件安装在车轮轴上且销轴齿轮组件采用球铰结构，销轴齿轮组件与齿轨自适应啮合。优点：一是销轴齿轮采用球铰结构实现销轴齿轮与齿轨的自适应啮合，保证传力可靠；二是销轴齿轮可以确保多个销轴滚子始终与齿轨啮合，具有较好的防脱轨和耐磨性，并且正反方向上不会产生齿间背隙；三是齿轨纵向承载能力大，满足列车在坡道上运行时驱动产生的纵向力需求；四是销轴齿轮组件的滚子在齿轨齿面上圆滑滚动，不会产生敲齿声，减少了振动；五是改善小曲线半径地段传统条形轨枕横向阻力低、大坡度地段道床纵向稳定性不足的问题。
