在行星齿轮传动中,采用少齿差内啮合传动,可以获得大的传动比。但是由于齿轮干涉,这一结构的采用受到了限制。为了避免干涉的发生,就要采用移距修正和短齿。在少齿差内啮合的几何学计算中,主要的问题: 1.保证没有干涉的发生; 2.保证足够的重合系数; 3.为了提高传动效率,改善构件受力,选取尽可能小的啮合角α。为了减少计算的繁锁,《工程机械》1975
In the planetary gear drive, the use of less teeth within the meshing transmission, you can get a large gear ratio. However, due to gear interference, the use of this structure is limited. In order to avoid the occurrence of interference, it is necessary to use the shift correction and short teeth. In the calculation of the geometry of internal teeth less tooth difference, the main problems: 1. To ensure that no interference occurs; 2. To ensure a sufficient coefficient of coincidence; 3. In order to improve the transmission efficiency, to improve the component force, select the smallest possible engagement Angle α. In order to reduce the cumbersome calculation, “Construction Machinery” 1975
