Yan Shidang, Liu Zhongming, Zhang Zhihong, et al. Analysis of the Dimension Chain of Large Crane Reducer[J]. 2015,39(11):118-120. DOI: 10.16578/j.issn.1004.2539.2015.11.028.
Based on a typical component in the large crane reducer as the object,a three-dimensional tolerance model is established.Through sensitivity numeric analysis,the critical and non-critical dimensions influencing the assembly requirements can be found out,the reasonable distribution of each component tolerances can be achieved,which lays a basis for the optimization of components accuracy design.
