摘要: 为提高传动系统的承载能力和平稳性,我国最新研制400 km/h高速列车传动系统首次采用双斜传动齿轮,双斜传动齿轮安装误差及特有的对称度误差会引起两端齿面偏载,降低齿轮服役寿命。建立考虑齿轮传动系统的车辆轨道耦合动力学模型,获取双斜传动齿轮在轮轨激励环境下的动态接触载荷,分析不同加工和安装误差形式下的齿轮偏载行为。结果表明,小齿轮轴向约束下,双斜传动齿轮存在10 μm和50 μm的对称度误差时齿面接触载荷平均误差达到了17.2%和145.3%;小齿轮轴向浮动下,双斜传动齿轮存在100 μm的对称度误差时齿面接触载荷平均误差为1.0%,可以有效改善双斜传动齿轮的偏载行为;轻微的平行度安装误差会导致单个齿面发生明显的偏载行为,但是左右齿面接触载荷分布基本保持一致;通过齿面修形可以抑制高速列车双斜传动齿轮的部分偏载行为。研究结果为确定我国新一代高速列车双斜传动齿轮的加工误差参考值和安装形式提供了指导意义。

Abstract: To improve the carrying capacity and stability of transmission system, the transmission system of the newly developed 400 km/h high-speed train in China adopts double-helical transmission gear for the first time. The installation errors and unique symmetry errors of double-helical gear will lead to deviation load on the gear surfaces at both ends, reducing the service life of gears. This paper established a train-track coupling dynamic model considering the gear transmission system to obtain the dynamic contact loads of double-helical gear in wheel-rail excitation environment, and analyzed the gear deviation load behavior under different forms of machining and installation errors. The results show that, under the axial constraint of small gear, when symmetry errors of 10 μm and 50 μm exist in the double-helical gear, the average errors of gear surfaces contact load reach 17.2% and 145.3%, respectively. Under the axial floating of small gear, when symmetry error of 100 μm exists in the double-helical gear, the average error of gear surfaces contact load is 1.0%, which can effectively improve the deviation load behavior of double-helical gear. Slight parallelism installation errors can cause significant deviation load on individual gear surfaces, however, the contact load distribution of left and right gear surfaces remains generally consistent. The partial deviation load behavior of the double-helical transmission gear of high-speed train can be suppressed by modifying the gear surface. The research results provide guidance for determining the reference value of machining error and installation forms of double-helical transmission gear in China’s new generation of high-speed train.
