A gearing forest automaton to automate a gearing system

Abstract A gearing system design completely depends on the designer’s skills and experiences because there is no theory or method to standardize the design process. In this paper, a gearing forest automaton is presented to implement automatic formation of design schemes from the original data without any human intervention. Firstly, a gearing tree is defined to describe a gearing system, and a two-shaft connection by M-transmission shafts (M ≥ 0) and an N-shaft connection by a transmission shaft (N ≥ 3), which can iteratively be combined into any gearing system, are denoted with data structure and automatically achieved. Secondly, the connection methods are both the input alphabet and transition functions of the gearing forest automaton. The start state comprises the original data and the accept state outputs the design schemes. Therefore, an entire design process becomes the construction and running of the automaton. The automaton is optimized to increase efficiency. Finally, according to this automaton, a computer program has been developed, and it is validated through three examples in which design quality is significantly improved.
