| 摘 要： | 采用齿轮啮合仿真和承载啮合仿真技术，研究了重合度达到2.0的弧齿锥齿轮的齿距误差对啮合性能的影响，针对航空弧齿锥齿轮允许的齿距误差，研究了误差量值对齿轮实际重合度，传动误差、齿间载荷分配和弯曲强度的影响。结果表明，相对齿距误差将降低齿轮的实际重合度，使单齿承受的载荷量增加，边缘接触加剧，弯曲强度不过，在容许范围内的齿距误差将不会严重影响重合度达到2.0的齿轮传动的性能。

| Abstract: | 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 of aviation gears, then the influence of this error on real contact ratio,transmission error,load distribution on tooth surfaces and load share between teeth were analyzed numerically. The conclusions state clearly that rear contact ratio will be reduced, load on single tooth surface will be increased, edge contact will be serious, bending strength will be reduced. But, if the related pitch error is small and permitted by accuracy standard of aviation gears, the meshing behavior of spiral bevel gears with contact ratio 2.0 will be not effected. |
