渐开线少齿差行星齿轮减速器的设计 （零齿差输出机构） 摘要 在条件为输入转速为1450转/分钟、输入功率为5KW、传动比为25等这些技术参数的基础上设计一渐开线少齿差行星齿轮减速器。 渐开线行星齿轮减速器传动与普通定轴减速器传动相比具有承载能力大、体积小、效率高、重量轻、传动比大、噪声小、可靠性高、寿命长、便于维修等优点，同时还可以提高其承载能力。 本设计最主要的过程就是少齿差和零齿差设计参数的选取与计算，特别是变位系数的选取，需通过Matlab 软件编程计算，这样很大程度上节省了因选取的变位系数不当而需重新计算所需要的时间。还可以多次给定初值选取最佳的变位系数，从而有利于少齿差和零齿差的结构设计。同时还需对轴类零件、端盖、箱体的结构设计，装配时，需要对轴承、密封圈、挡圈、键进行选用。 关键词：减速器 行星齿轮 优化设计 Involute few tooth difference planet gear reduction gear design (zero tooth difference output element) Abstract The planet gear reduction gear with few-tooth difference transmission and the ordinary dead axle reduction gear transmission compares has the bearing capacity in a big way, the volume small, the efficiency high, the weight light, the velocity ratio big, the noise small, the reliability high, the life long, is advantageous for merits and so on service, meanwhile may sharpen its bearing capacity. This design process most main is the few tooth difference and the zero tooth difference design variable selection and the calculation, specially dislodges the coefficient the selection, must through the Matlab software programming computation, save like this to a great extent because of the dislodgement coefficient which selected not when had the recomputation to need time. It also may many times assign the starting value selection best dislodgement coefficient, thus is advantageous to the few tooth difference and the zero tooth difference structural design. When simultaneously also needs the counter shaft class components, the end cover, the body structural design, the assembly, needs to the bearing, the seal packing collar, the elastic ring, the key to carry on selects.
