Abstract: According to the meshing principle of the chain drive formula of coordination transform and the pitch variation principle of dual phase Hy-Vo silent chain, the formula of the inner tooth profile curve of dual phase Hy-Vo silent chain is built. The mathematical model of the inner tooth profile curve of the new chain plate is established. The dynamic model of quasi-conjugate meshing between the working chain plate of silent chain and the involute sprocket is established. The new type silent chain system with inner tooth profile is compared with the previous conventional silent chain system. The simulation results show that the new type Hy-Vo silent chain system has less lateral fluctuation of chain plate and less change of angular velocity of chain plate, and moves more smoothly. The rationality of the mathematical model and the superiority of the dynamic model of the new type Hy-Vo silent chain system with inner tooth profile are verified.
