[Abstract]:In this paper, the National Natural Science Foundation of China: "Multivariate variation and meshing Mechanism of Dual-phase Transmission Hy-Vo Tooth chain system" (51305154) and "meshing Design Theory of Multi-axis High-Speed Tooth chain system based on complex constrained Boundary conditions", "51275207J, Ji" Project of Forest Province Science and Technology Project: "Research on key Technologies of Hy-Vo Tooth chain system with Multiphase Transmission", supported and funded by 2050204075GX, The parameter design of the chain plate and the two-phase sprocket of the two-phase transmission Hy-Vo tooth chain system is completed, and the design calculation of the system is carried out, and the mathematical model of each part of the system and the multi-body dynamics simulation model of the system are established. The simplified rigid-flexible coupling analysis model. The multi-body dynamics and rigid-flexible coupling characteristics of two-phase transmission Hy-Vo toothed chain are studied by simulation and analysis. Based on the meshing theory of tooth chain, the meshing design system of dual-phase sprocket, chain plate and gear shaper is established. The inner and outer composite meshing chain plate and outer meshing chain plate in dual-phase transmission Hy-Vo tooth chain system are studied. The active biphase sprocket and driven biphasic sprocket are designed and calculated, and the system layout is designed. By establishing the multi-body dynamics simulation model of the Hy-Vo tooth chain system of dual phase transmission, the track of the link motion, the fluctuation of the tight edge of the chain, the interlink tension, the instantaneous transmission error of the system and the change of the angular velocity of the chain plate under different rotational speeds are analyzed. The analysis results show that the dual-phase transmission Hy-Vo tooth chain system has good transmission performance, compared with the corresponding single-phase transmission Hy-Vo tooth chain system, its transmission error is smaller and the transmission is more reliable. The rigid-flexible coupling analysis model of dual-phase transmission Hy-Vo tooth chain system is constructed and simplified to analyze the rigid-flexible coupling characteristics of the system. The analysis results show that the inner tooth profile of the outer meshing tooth chain does not participate in the meshing and is the same as the actual situation, and the inner and outer composite meshing chain plate realizes the characteristics of the inner and outer composite meshing very well, which embodies the good transmission performance. The contact line between the two intermeshing pin shafts is gradually moved up in the process of the chain from the straightening state to the complete positioning state, which is in accordance with the actual situation. The design of the system is reasonable, and the stress distribution and strength of each component meet the design requirements. By comparing and analyzing the fluctuation of center distance of Hy-Vo tooth chain system with different meshing mechanism, which is composed of two phase transmission Hy-Vo gear chain system according to different series-connected sequence, the variation of the center distance of the chain plate with different meshing mechanism under the same rotating speed is compared and analyzed. The relationship between transmission performance and meshing mechanism of dual phase transmission Hy-Vo tooth chain system is studied. The analysis results show that the performance of the inner and outer composite meshing chain plate is better than that of the outer meshing chain plate. In the system, the more nodes of the inner and outer composite meshing chain plate, the smaller the fluctuation of the system is, which is consistent with the conclusion of the theoretical analysis. To sum up, the design calculation and simulation analysis method of Hy-Vo tooth chain in this paper is feasible. According to this method, the dual phase transmission Hy-Vo tooth chain system has good transmission performance. It meets the design requirements well and is of great significance to the further study of the gear chain system of dual phase transmission.
