摘要
错位量通常以两齿面啮合时沿着啮合线方向偏差的最大值来评定,利用动态单面啮合测量原理和虚拟仪器技术,集成高精密圆光栅角度测量传感器和通用硬件设备,搭建了一套可模拟齿轮错位量的传动误差测量试验台,具有贴合实际工况、自动化程度高、测试精度高和人机交互友好等优点。以变速箱中齿轮副为研究对象,利用带载启动在贴近实际工况下进行接触斑点试验,模拟验证了齿轮啮合错位对传动误差的影响。通过齿向鼓形修形对齿轮错位角进行补偿,可优化齿轮修形并提升变速箱的整机性能。
The amount of misalignment is generally evaluated by the maximum deviation of the meshing line direction when the two tooth surfaces are meshed.The dynamic gear transmission error measurement principle and virtual instrument technology are used to integrate a high-precision circular grating angle sensor and general hardware equipment.The transmission error test bench measurement system for analog gear misalignment has the advantages of fitting actual working conditions,high degree of automation,high test accuracy and friendly human-computer interaction.Taking the gear pair in the gearbox as the research object,using the load-starting to carry out the contact spot test under the actual working condition,the influence of the gear meshing misalignment on the transmission error is verified by the simulation.Through compensating the gear misalignment angle by the tooth-to-drum shape modification,the gear shape can be optimized and the overall performance of the gearbox can be improved.
