摘要：Based on the transmission principle of the positive-drive cam mechanism,
   the tooth profile theory of a new type of
   liner-movable-gear-drive-mechanism with arbitrary tooth difference is
   proposed. The tooth profile equation of the shock wave and the center
   wheel is proposed, and the geometrical proof of the indirect conjugation
   of the tooth profile and the center tooth profile is carried out. The
   relationship among the number of movable teeth, the number of teeth of
   the shock wave and the number of teeth of the center wheel is deduced,
   and the feature that movable teeth should distribute uniformly is
   proved. The transmission ratio of the new movable gear extension is
   deduced in term of the relative angular velocity method. The design
   examples are provided to show the adoptability of the two kinds of tooth
   profile given, symmetrical tooth profile and asymmetric tooth profile.
