【摘要】：近年来,流体动压旋转轴密封技术成为旋转轴密封技术发展的一个重要方向。该技术是基于流体的动压效应在密封接触面形成一层油膜,提高了密封唇的润滑效果,降低了密封唇的摩擦热及磨损,进而提高了旋转轴密封的使用寿命。该技术自从被发现以来,广泛应用于各种旋转轴密封,例如各种波形油封、偏置O型圈、Kalsi密封等等,本课题主要结合成型旋转动压径向密封机理及其结构优化设计方法研究这一研究项目,针对挤压型旋转轴密封的密封性能进行研究。本论文的研究内容主要包括以下三个部分:首先对国内外各种流体动压技术进行了探究,研究了流体动压技术的动压效应。通过结合软弹性流体动压润滑的求解问题以及雷诺方程提出了求解流体动压润滑油膜的求解方法。其次结合kalsi密封,通过三维建模软件Pro/E建立起具有正弦波形密封的模型,然后借助有限元仿真分析软件ABAQUS对该密封进行仿真研究,分析具有不同正弦波形参数条件下密封唇的接触应力以及不同波形参数对密封性能的影响,并对普通波形密封的密封唇参数设计进行了理论设计。最后是试验台的设计,根据该密封实验要求以及相关试验台设计标准确定了试验台的设计方案,借助于Solid Works进行三维建模,完成试验台样机的开发,并绘制了零件工程图纸,完成了试验台的搭建。
[Abstract]:In recent years, hydrodynamic rotary shaft seal technology has become an important direction of development of rotary shaft seal technology. This technique is based on the hydrodynamic pressure effect to form an oil film on the seal contact surface, which improves the lubricating effect of the seal lip, reduces the friction heat and wear of the seal lip, and further improves the service life of the rotary shaft seal. The technology has been widely used in various rotary shaft seals since its discovery, such as various waveform oil seals, offset O-rings, Kalsi seals, etc. In this paper, the mechanism of rotary dynamic pressure radial seal and its structural optimization design are studied, and the seal performance of extruded rotary shaft seal is studied. The main contents of this thesis include the following three parts: firstly, various hydrodynamic pressure technologies at home and abroad are explored, and the hydrodynamic pressure effects of hydrodynamic pressure technology are studied. The solution method of hydrodynamic lubrication film is proposed by combining the solution of soft elastic hydrodynamic lubrication and Reynolds equation. Secondly, combined with kalsi seal, the model with sine wave seal is established by Pro/E, and then the seal is simulated by the finite element simulation software ABAQUS. The contact stress of seal lip with different sinusoidal parameters and the influence of different waveform parameters on seal performance were analyzed. The design of seal lip parameters of ordinary waveform seal was carried out theoretically. Finally, it is the design of the test-bed. According to the requirements of the sealing experiment and the design standard of the test bed, the design scheme of the test-bed is determined, and the three-dimensional modeling is carried out with the help of Solid Works, and the prototype of the test-bed is developed, and the part engineering drawings are drawn. The construction of the test bench has been completed.
