HGT准双曲面齿轮传动的轮齿接触分析

摘要

In machining hypoid gear with the HGT method, the large gear is machined with generated method and the pinion is machined with "tilt" method. Based on the machining principle and method of Gleason hypoid gears machined by the HGT method and on the basis of traditional machine tools with cradle mechanism, the mathemati-cal model of machining was established and the theoretical tooth surface equations were derived;on this basis, the tooth contact analysis ( TCA) including tooth contact analysis and edge contact analysis was carried out. The above steps are programmed on the computer;using numerical simulation, we can display the different parameters, gear meshing process and performance with different misalignment, verifying that the mathematical model and theoretical derivation is correct;we believe that this may serve as the foundation for Loaded Tooth Contact Analysis ( LTCA) .%HGT准双曲面齿轮，大轮采用展成法加工，小轮采用刀倾法加工。根据格里森HGT准双曲面齿轮的加工原理和加工方法，并以传统的摇台型机床为基础，建立了切齿加工数学模型，推导了理论齿面方程，并对齿轮进行了轮齿接触分析（tooth contact analysis， TCA），包括齿面接触分析和边缘接触分析。将切齿设计与相应的TCA编制成计算机程序，通过计算机数值仿真，可准确显示不同参数、不同误差的齿轮啮合过程和性能，验证了数学模型与理论推导的正确性，为下一步轮齿承载接触分析（ loaded tooth contact analysis， LTCA）打下了基础。
