摘　　要：齿轮修形是改善齿轮传动特性的一种重要手段。提出了新的齿廓方向刀具圆弧修形及齿向鼓形修形的拓扑修形方案,利用齿轮啮合原理、齿轮接触分析(TCA)技术设计了修形参数,并研究了修形齿轮的误差灵敏度,包括螺旋角和压力角误差对接触印痕及传动误差的影响。研究表明,这种修形方案的误差灵敏度低,而且没有边缘接触,啮合性能较好。研究成果为斜齿轮修形设计提供了理论依据。The gear modification is an important technique to improve gear transmission performance. A new topological modification method with circular tooth profilein gear cutter and tooth drum-shaped is put forward. Based on the gear meshing theory and the tooth contact analysis(TCA) technology,the modification parameters for helical gear are designed,and error sensitivity is studied,that is,the effects of helix angle and pressure angle errors on the transmission error and contact trace. The study shows thats gear with the proposed topological modification is insensitive to the helix angle and pressure angle errors,and it has good performance without edge contact. The result provides a theoretical foundation for the modification of helical gear.
