摘要
采用齿轮啮合仿真和承载啮合仿真技术 ,对重合度达到 2 .0的航空弧齿锥齿轮的齿距误差的影响进行了研究。首先定义了航空弧齿锥齿轮相对齿距误差 ,选取了量级 ,研究了这一误差对齿轮实际重合度、传动误差、齿面载荷分布和齿间载荷分配的影响。进一步又分析了在一定齿距误差下载荷变化的影响以及固定载荷下误差变化的影响 。
Applying TCA(Tooth Contact Analysis)and LTCA (Loaded Tooth Contact Analysis) techniques,the influence of pitch error on the meshing behavior of aviation spiral bevel gears with contact ratio 2 0 was studied.First,the relative pitch error was defined and its amount was selected according to the accuracy degree of aviation gears,then the influence of this error on the real contact ratio,transmission error,load distribution on tooth surfaces and load share between teeth was analyzed numerically.Further,the effects of load changes under certain pitch error and pitch error changes under certain load were analyzed to provide conditions for application of aviation spiral bevel gears with high contact ratio.
