| 摘要: |
| 传动误差是评判弧齿锥齿轮啮合性能的重要指标之一,直接反映弧齿锥齿轮的传动啮合特性,其与轴系结构密切相关. 本文主要研究轴系结构与传动误差之间的正向设计计算方法,提出一种基于通用软件工具平台的考虑轴变形影响的弧齿锥齿轮传动误差数值计算方法,并与国际先进弧齿锥齿轮设计软件（KIMoS软件）进行对比,验证本文计算方法. 针对两种轴系结构设计方案,应用本文方法分析轴变形对航空发动机弧齿锥齿轮传动误差的影响. 分析计算结果表明:支撑形式对齿面接触力的大小影响甚微,但支撑形式与轴的变形对传动误差的影响较大. 通过改变轴系的支撑结构可以获得良好的弧齿锥齿轮传动误差曲线. 本文工作可为研究轴系结构与零度弧齿锥齿轮传动误差关系提供参考. |

| Abstract: |
| Transmission error, to a certain extent, is one of the most important indexes to evaluate the meshing performance of spiral bevel gears, which directly reflects the transmission meshing characteristics of the Spiral Bevel Gears and is closely related to the shafting structure. This paper mainly studies the positive design calculation method between shaft structure and transmission error, and proposes a numerical calculation method of the spiral bevel gear transmission error considering the influence of shaft deformation based on the common software tool platform. It is compared with the international advanced design software (KIMoS software) of spiral bevel gear to verify the calculation method of the paper. The influence of shaft deformation on the transmission error of aero-engine spiral bevel gears is analyzed aiming at two kinds of design schemes for shaft structures in this paper. The analysis results show that the different forms of support have little effect on the contact force of the tooth surface, but the support form and the deformation of the shaft have a greater impact on the transmission error. Good transmission error curve of spiral bevel gears can be obtained by changing the support structure of the shafting system. Therefore, the work of this paper can provide reference for studying the relationship between shafting structure and transmission error of spiral bevel gear. |
