英文摘要：

The tooth profile equations of central inner gear and geometry analysis of the two-tooth swing movable tooth transmission are comprehensively and detailed studied with ferrari solution and cardan formula etc.The curvature has been simulated and addendum curvature parameters trend are analyzed on the basis of the above analyzed.Using the condition of no interference appearance on inner gear＇profile,the range of movable tooth radius is estab qlished.The comprehensive effects of parameters,such as the transmission ratio,cam＇s theoretic half-axis size and movable tooth＇s radius,on addendum curvature by the curvature formulate analyzed,identifying the relationship between pressure angle formula and the corner of the sliding tooth,according to which an analysis is made on minimum pressure angle features related to structural parameters.The algorithm,analysis and results presented can be used as the references for geometrical design of this type of geometric design and accuracy analysis.
