The problems of parameter selecting selection and geometrical design of the movable rolling tooth transmission with cam actuating are studied.The comprehensive influence of tooth profile parameters,such as the transmission ratio,cam＇s theoretic cam half-axis size length,and radius of the movable rolling tooth,on tooth profile property of the inner gear is analyzed,and the value selecting selection relationship of the values ofamong tooth profile parameters is established using under the condition of no interference appearance on inner gear＇ profile.According to the transmission principle and structural characteristics analysis of the movable-tooth-frame,the calculation formulae and selecting selection conditions of the geometrical parameters of movable-tooth-frame for avoiding parts movement interference and,meeting the assembly requirement and transmission continuity are proposed.On the basis of the above analyzinganalysis,the steps for geometrical parameter design of the movable rolling tooth transmission with cam actuating are presented,and the geometrical design process of this kind of transmission equipment is illuminated illustrated by means of an example.It＇s shown that the design course of the movable rolling tooth transmission with cam actuating can be simplified,and satisfied parameter combination can be obtained by useon the basis of the value selecting selection relationship of tooth profile parameters,the selecting selection conditions of movable-tooth-frame parameters as well as the parameter design steps presented.
