刀倾全展成准双曲面齿轮的切齿设计

Machine-tool settings design for HGT hypoid gear drives

摘要:

为提高准双曲面齿轮的啮合性能，对刀倾全展成(HGT)准双曲面齿轮进行切齿设计研究．以局部综合法(Local Synthesis)为基础，并依据格里森准双曲面齿轮的加工原理，得到满足一定啮合性能的加工参数，并采用该参数对齿轮副进行轮齿接触分析(TCA)． 从齿面印痕和传动误差曲线可以看出，齿轮副重合度大，传动平稳，可通过调整局部控制参数来改变齿轮的啮合性能，验证了切齿设计的正确性．该方法可通过对设计参考点及其领域内的啮合条件进行预控，达到对齿面啮合质量的控制．

Abstract:

To obtain high quality gear, the machine-tool settings design is studied for HGT hypoid gears. Using local synthesis method as the basis, and based on the machining principle of Gleason hypoid gear, the machine-tool settings are obtained which can satisfy certain meshing performance, and then the tooth contact analysis is done. From the contact pattern and transmission error curve we can see that the gear pairs has big coincidence degree and stable transmission, and its meshing performance can change through the adjustment of local control parameters, so the correctness of the machine-tool settings design is verified. This method can get the optimal machine-tool settings through pre-controlling the meshing condition of the design reference point, and it has a significance for designing high precision hypoid gears.
