A cylinder sine oscillating tooth mechanism with a large stiffness,light mass and compact sized is proposed according to the transmission characteristics of the oscillating tooth mechanism and non-circular gear. First,the variable speed ratio transmission theory and the continuous transmission conditions of mechanism are introduced. Second,the maximal number and the arrangement rules of oscillating teeth in the gear transmission are studied. Third,the tooth profile surface equation of the wave generator and the central gear are established. Fourth,two configuration method of cylinder sine oscillating tooth mechanism with motion integration are analyzed based on the transmission ratio characteristics. Fifth,the pressure angle model of mechanism of is built. Finally,through simulation and parametric analysis,the cylinder sine oscillating tooth mechanism is designed to achieve motion integration,and the factors affect the pressure angle are discussed. The studied results provide a theoretical foundation for the oscillating tooth mechanism with motion integration design.
