[Abstract]:Rolling coupling is a patent technology developed in the research of national science and technology research project. Its structure form is unique and its transmission performance is good. It is an advanced flexible coupling. At present, the design theory of rolling coupling is not perfect, its mechanical properties and transmission characteristics are affected by its structural parameters, and the law of influence on medium factors is not clear. Based on this, the mechanical analysis of rolling coupling is carried out in this paper, which provides a valuable theoretical basis for the design, analysis and application of rolling coupling. The main research work of this thesis is as follows: According to Hertz theory, the contact force model of rolling body and raceway is established, and the theoretical calculation method of elastic contact stress and elastic deformation between rolling body and raceway is given. On this basis, the contact strength is analyzed and the working speed is revealed. The influence of the structure parameters of rolling body and raceway on its contact strength. The finite element analysis model of semi-coupling is established by using Ansys software. The stress of semi-coupling under rated load is calculated and analyzed. The influence of different rotational speed, keyway position and structural size of semi-coupling on the stress is obtained. It provides theoretical basis for strength design of rolling coupling. Then the coupling matrix method is used to establish the mathematical model of the force acting on the rolling coupling, and combined with the lumped parameter method, the misalignment vibration equation of the rolling coupling rotor system is established and solved, and the transmission torque is analyzed and revealed. The influence of the working speed and misalignment on the transmission characteristics of the rolling coupling provides theoretical support for the analysis of the misalignment drive of the rolling coupling. On the basis of the above research, according to the structure characteristic, dimension relation and mechanical characteristic of rolling coupling, the parametric design software of rolling coupling is developed by combining Matlab and Ansys APDL parametric design language. To provide an efficient design and analysis tool for the design, analysis and application of the rolling coupling. Finally, the strain of the rolling coupling under the condition of simulated rated load is measured by the electric measurement method. The correctness of the finite element simulation analysis results is verified by comparing and analyzing the experimental values and the simulation results. The research results in this paper are of great theoretical significance and engineering application value in improving the design level of rolling coupling and shortening the design period of rolling coupling.
