摘　　要： 采用一种经试验验证过的3D轮齿接触分析(TCA)方法,研究1对直齿轮和7对斜齿轮在同等载荷强度下,轴向重合度对传动误差的影响.为保证结果更接近实际情况,在计算时考虑由加工误差导致的齿轮啮合错位量和适当的微观修形.结果表明:齿轮轴向重合度为略大于整数的值时,其传动误差最小,如1.02~1.05. A pair of spur gears and seven pairs of helical gears were studied to investigate the influence of overlap ratio on transmission error under the same load intensity by using a validated 3D-Tooth Contact Analysis（ TCA） method. To ensure the results being closer to the actual situation,mesh misalignment due to manufacturing deviations and appropriate micro modifications will be applied to the gears. The results show that when the overlap ratio is slightly greater than an integer constant,the transmission error is minimum; for example the overlap ratio is equal to 1. 02 ~ 1. 05.
