摘要
基于柴油机窜轴导致传动齿轮断齿故障案例,针对该故障实验模拟难度大,窜动量、窜动形式无法控制,无有效方法提取窜轴时齿轮载荷进行分析的现状,综合运用Creo、ADAMS软件建立柴油机齿轮系动力学仿真模型。进行无窜轴、单向窜轴、往复窜动3种工况的仿真,提取曲轴窜动量与传动齿轮接触力进行关联性分析,得到了发生窜轴故障后齿轮动态载荷变化规律。验证了窜轴会导致齿轮过载、调幅及冲击振动。证明了借助动力学仿真技术进行窜轴故障影响研究具有可行性。
Based on a gear tooth fracture case,which is caused by diesel engine crankshaft axial movement. Aiming at the situation that it＇s difficult to simulate this fault by experiment,the displacement and movement type can＇ t be control. And there is no effective method to extract gear load during the crankshaft axial movement for analysis by experiment. By using Creo,ADAMS software,the gear transmission system dynamics simulation model is built and the no axial movement,one-way axial movement and reciprocating axial movement scenarios is simulated. The gear load change rules during the shaft axial movement is got by extracting the shaft displacement,the gear load and analyzing the relationship between them. The shaft axial movement can cause gears over load,amplitude modulation and impact vibration is verified. The feasibility of the study on the influence of spindle axial movement based on dynamics simulation is proved.
