文档介绍：安徽工业大学毕业设计(论文)说明书 I 摘要传统的摆线针轮减速机精确度不够,不能应用于精密传动的场合,本课题旨在改进传统的行星针轮摆线减速机,提高精度和效率。通过改进齿轮啮合副以及使用精度更高的等速输出机构来实现。本设计通过对基本机构的分析来确定本设计机构的可能性,然后通过接触强度的计算进行摆线轮尺寸的确定,摆线齿轮的尺寸确定后就可以确定针轮的尺寸,通过摆线齿轮的尺寸来初步确定十字盘的尺寸,通过对十字盘的校核来验算尺寸是否合格,不合格继续修改参数,进行下一轮计算,直到算出合格的参数为止。然后通过选取联轴器来确定轴的最小尺寸,在根据轴上零件尺寸来确定各轴段尺寸,最后确定整个减速器的尺寸。通过查阅公式进行了一系列计算后,各零部件的强度都符合要求,确定了本设计的改进方案在理论上的合理性和可行性。关键词: 行星传动摆线齿轮十字钢球等速输出机构变齿厚安徽工业大学毕业设计(论文)说明书 II Abstract Traditional cycloidal reducer precision is not enough, can not be applied to precision transmission occasions, this subject aims to improve the traditional needle wheel ary cycloid reducer, improve accuracy and efficiency. By improving the gear meshing pair and use higher precision constant output mechanism. This design through the analysis of basic mechanism to determine the possibility of the anization, and then through the calculation of contact strength for determination of cycloid gear size, the size of the cycloidal gear is determined can determine the size of needle wheel, through the size of the cycloidal gear to preliminarily determine the dimensions of the cross plate, plate through the cross checking to check the size whether qualified, unqualified continue to modify parameters, calculation of the next round until work out qualified parameters. Then select coupling to determine the minimum size of shaft, in according to the size of shaft parts to determine the various s
