| 摘 要： | 针对传统外啮合齿轮箱功率密度较小，传递大功率时增大模数而导致齿轮箱尺寸剧增的问题，基于渐开线标准齿轮传动正确啮合条件及重合度计算理论，提出以多路功率分流外啮合定轴齿轮传动替代传统单外啮合齿轮传动，根据啮入点啮入时序排布方式，设计了同步啮入与依序逐步啮入两套方案。以3路功率分流的外啮合定轴齿轮传动为案例，通过复合重合度计算推导，发现在相同重合度下，与同步啮入时序方案相比，采用依序逐步啮入时序方案，齿轮传动更为平稳，在相同传动比、相同模数情况下，齿轮承载能力提高1/3。由此得出结论，以多路功率分流外啮合定轴齿轮传动，并采用各路啮入点依序逐步啮入时序方案，可以在有效提高齿轮箱的功率密度，大幅减少齿轮箱尺寸基础上，获得平稳传动，提高齿轮承载能力。

| Abstract: | To improve the power density of externally meshing gear box and to reduce the dimension of the gear box at large power transmission, multi-channel power split externally meshing fixed-axis gear transmission was presented based on standard gear transmission meshing condition and contact degree calculation theory to replace the traditional single externally meshing gear transmission. Synchronously meshing-in time sequence scheme and gradually ordered meshing-in time sequence scheme were designed in accordance with the meshing time sequence arrangement mode. In the case of three-channel power split externally meshing fixed-axis gear transmission, the gear transmission of the gradually ordered meshing scheme is more smooth compared to that of the synchronously meshing scheme, with the bearing capacity of the gear increasing by 1/3 under the same contact degree, the same transmission ratio and the same modulus. The results indicate that multi-channel power split externally meshing fixed-axis gear transmission integrated with the gradually ordered meshing scheme can implement smooth transmission and improve the gear bearing capacity while effectively increasing the power density of the gear box and reducing the dimension of the gear box. |
