[Abstract]:With the development of modern industry, as the core of the strategic industry rapidly lead manufacturing innovation to intelligent manufacturing, oil seal on the application put forward urgent demand. Therefore, the sealing of in-depth study, as well as the need for technical product design technology of oil seal innovation, so as to shorten the design cycle, improve design efficiency. Based on the sufficient research on skeleton oil seal product design of rotary parameter on the role of the key influencing factors on the rotary seal and sealing function of the relationship between the performance of the numerical simulation and analysis, summed up the law summed up the key parameters influence on overall performance, and the analysis result feedback to product design, and then put forward the application of series design method and module configuration design method. (1) according to the features of the rotary seal, through analysis of its structure, summarizes the decisive on sealing performance The influence of structure parameters. This paper focuses on the structure parameters include: the amount of interference, the oil surface angle, gas plane angle, R value, waist thickness, waist length. At the same time, also made a research on the pressure spring and the cavity. Through the analysis of the key parameters for laws of influence on the sealing performance, provide reference for the study design and Research on sealing performance of further products. (2) the flow issue of skeleton oil seal lip contact analyzes the fluid dynamics of ideal conditions. The two aspects of theoretical model from the analysis of the pump suction main lip seal with inclined lip region: structure and contact surface wrinkles with asymmetric structure firstly. Take the main lip with the area, different structure parameters and different operating conditions, the asymmetric inclined lip structure and pump function relationship are discussed; secondly, the ideal model for the contact surface wrinkle structure, and analysis The effect of pump suction effect. The results show that the relationship between the key parameters and the change of sealing performance have different rules of each. (3) through the practice of oil seal parametric design research project, summarizes the design features of rotary seal structure parameters. The features of structural design based on the combination of key parameters the oil seal and seal performance analysis results of the interaction, a method of modular configuration technology and series design of oil seal technology in product design, and was further studied. Aiming at the structure size of the seal, according to its relationship with the sealing function were classified according to the seal design. The dimensions of key feature size and the local feature size of corresponding series. In addition, according to the different parts of different functions, the module division, including the main lip of the sealing fluid The dustproof module, external vice lip module and skeleton assembly support modules. Different modules through the interface structure of product standardization, in order to obtain different series or the different functions of the products. The rotary seal structure and function characteristics determine the sealing structure analysis and Design Research Based on the performance of mutual study and put forward a series of accordingly. Design and modular configuration design method is used in the design of seal products, and applied to the parametric design system of oil seal, the further development of the design of the system, lay the foundation for improving the work quality and standard design of seal products.
