Study on automatic assembly technology for complicated gear trains based on topological unit

摘要

First the concept of topological unit was given in this paper. Five forms were proposed for compound complex topological graphs by using topology unit. Developed a drawing interface for human-computer interaction, this interface finished the work of graph drawing; graphic changes; split the complex topological graph; and the function of automatic assembly of epicyclic gear trains. Second, new methods of topological inversion were given, which facilitated the expression of the topology of computer information extraction. Finally, the series combination of topological elements as an example, an assembly process of epicyclic gear trains was given.
