【Abstract】 Counter-meshing gears mechanism is a coding and discrimination mechanism, which can be used for safety and arming surety applications. Based on a reported CMG instance, the structure, working principles and essential concepts of the CMG mechanism were briefly educed. The so called 2 dimensional maze-mapping method for CMG teeth-coding verification was presented. The method is simple, clear and easy for use. Applying the method to the same instance, some critical issues were analyzed in detail, and conclusions were given.更多还原
