[Abstract]:As a complex and high-end product series in the field of mechanical transmission, a new type of Hy-Vo tooth chain is a frontier research field of disciplines and industries formed on the basis of conventional chain transmission technology, especially in high speed, heavy load and low noise.Under the condition of large center distance, because of the double effect of variable pitch and internal and external composite meshing, its transmission performance is superior to synchronous belt transmission, gear transmission and roller chain transmission, which has become one of the preferred power transmission forms for many host manufacturers.This paper is supported by the National High Technology Research and Development Program, "Research and platform Development of Hy-Vo chain digitized Design based on complex Multivariate variation" project (2009AA04Z109).The rigid-flexible coupling contact dynamics of a new type of Hy-Vo toothed chain system is studied, and the noise and wear characteristics of the system are studied experimentally.In this paper, the application prospect and research significance of new type Hy-Vo tooth chain drive are described, and some problems in the research of tooth chain are pointed out, and the research status of tooth chain drive direction at home and abroad is summarized.In this paper, the development history and present situation of multibody dynamics and rigid-flexible coupling dynamics are introduced, and the relevant theories and algorithms are also introduced.In this paper, the contact dynamics simulation model of a new type of Hy-Vo toothed chain transmission is established by means of multi-body dynamics and modern contact dynamics, and the real simulation analysis of each chain plate and sprocket, chain plate and pin shaft of the new Hy-Vo tooth chain in the course of transmission is carried out.The change of contact force between pin shaft and pin shaft.The dynamic contact stress changes of flexible chain plate and flexible pin shaft are analyzed by using rigid-flexible coupling dynamics technique.The relationship between the inner tooth profile and the outer tooth profile of the chain plate and the contact region between the inner tooth profile and the sprocket are found, and the connection process between the inner tooth profile and the outer tooth profile of the chain plate and the sprocket engagement is analyzed.In this paper, the Hy-Vo tooth chain transmission noise test is carried out on the chain noise test rig with automatic speed change and automatic loading developed by ourselves.The noise spectrum characteristics of chain drive under different rotational speeds were studied by AWA6290A real-time noise analyzer.Chain wear tests were carried out on a closed force flow high speed wear test rig. The wear elongation and wear elongation curves of the chain were obtained. The wear morphology of the chain plate and the surface of the pin shaft was observed and analyzed.The rigid-flexible coupling contact dynamics analysis method in this paper has important reference significance and reference value for the contact analysis of other chain transmission, the contact analysis of gear pair and the analysis of chain stepless transmission.The new Hy-Vo tooth chain studied in this paper has been applied to the power transmission of steam turbine, high precision grinder, automobile gearbox and so on.The research results of this paper have important academic value and engineering practical significance.
