【摘要】：渐开线少齿差行星具有传动比大、体积小、重量轻、承载能力大、效率高等特点，具有广泛的应用前景。课题来源于国家自然科学基金项目（50705100），基于质量弹簧等价模型方法对新型渐开线少齿差行星齿轮机构建立了传动精度的仿真模型，并进行了仿真研究。对于进一步提高其传动精度、控制误差具有重要意义。论文主要内容如下： ⑴考虑了曲柄轴、行星齿轮、内齿轮、浮动盘、端盖的加工误差、装配误差以及齿轮啮合刚度、轴承刚度、负载等因素，建立了浮动盘式渐开线少齿差行星齿轮减速机构的动态传动误差仿真模型。 ⑵根据建立的仿真模型，使用Newmark求解方法，编制了matlab计算程序，并进行了不同误差参数下的仿真计算。 ⑶通过仿真计算，，找出了传动精度的主要影响因素，包括：端盖上销轴偏心误差、销轴半径误差，行星齿轮上轴承孔偏心误差、行星齿轮基圆偏心误差、行星齿轮齿形误差等。通过控制上述主要误差因素，可以有效提高传动精度。
[Abstract]:The involute planet with less tooth difference has the characteristics of large transmission ratio, small volume, light weight, large bearing capacity and high efficiency. Based on the equivalent model method of mass spring, a simulation model of the transmission accuracy of a new involute planetary gear mechanism with less tooth difference is established by the National Natural Science Foundation of China (50705100), and the simulation research is carried out. It is of great significance to improve the transmission accuracy and control error. The main contents of this paper are as follows: 1 the machining error, assembly error, gear meshing stiffness, bearing stiffness, load and so on of crank shaft, planetary gear, inner gear, floating disk and end cover are considered. The dynamic transmission error simulation model of the planetary gear reducer with floating disc involute with less tooth difference is established. 2 according to the established simulation model, the matlab calculation program is compiled by using the Newmark solution method. The main influencing factors of transmission accuracy are found, including: offset error of upper pin shaft, radius error of pin shaft, eccentric error of bearing hole on planetary gear, and so on. Planetary gear base eccentric error, planetary gear tooth shape error and so on. By controlling the main error factors mentioned above, the transmission accuracy can be improved effectively.
