Abstract: Counter-meshing
gears (CMG) mechanism is a discrimination mechanism mainly used in high
consequence systems, and discrimination-teeth coding is its kernel
design issue. To get optimum coding result with minimum gear levels,
classification method of CMG mechanism is studied from the point of view
of its coding characteristics. With pre-proposed maze mapping method,
the CMG mechanism is classified as three types by maze attributes and
unlocking-route topologies. The second type is novel, which can be
reset, locks up immediately with any wrong code symbol, and easy to
code. Some important concepts and analysis method are also presented,
which are foundations to understand CMG’s structure, principle and
design.
