摘　　要：以某航空减速器齿轮副为研究对象,采用KISSsoft软件,对齿轮进行修形研究。通过选用合适的修形方法对修形前、后的齿轮进行了啮合性能及接触研究,主要对轮齿强度、传动误差、齿面载荷分布、滑动率展开对比。结果证明,对斜齿轮进行适当地修形可提高轮齿承载能力,改善齿轮啮合性能,减少了齿顶、齿根受载过大及载荷突变等问题的产生,从而提高了啮合质量。最后通过与实际齿轮接触印痕对比分析证明了KISSsoft的分析结果有效可靠。Taking a certain helical gear pair in aero gearbox as the research object,the gear modification is analyzed with KISSsoft software.The helical gear tooth is modified by suitable method,the meshing performance and contact analysis of the gears before and after modification are studied,mainly comparing the parameters of the tooth strength,transmission error,tooth surface load distribution and sliding ratio.It is concluded that reasonable modification on the inclined gear can improve the endurance capacity and the meshing performance of gear,and can reduce the excessive roof,root overload and the load mutation phenomenon;thus it effectively improves the meshing quality.Through the comparative analysis with the actual gear contact pattern,it shows that the analysis results of KISSsoft are effective and reliable.
