【Abstract】 In order to design the model of gear in Pro/ENGINEER ,the evolute’s equation of gear tooth figure was deduced in this paper,and base on it,the program and relation equation of alterable parameter were designed,in the end the alterable design of a parameter model of gear was finished.更多还原
