【摘要】：近年來,流體動壓旋轉(zhuǎn)軸密封技術(shù)成為旋轉(zhuǎn)軸密封技術(shù)發(fā)展的一個重要方向。該技術(shù)是基于流體的動壓效應(yīng)在密封接觸面形成一層油膜,提高了密封唇的潤滑效果,降低了密封唇的摩擦熱及磨損,進而提高了旋轉(zhuǎn)軸密封的使用壽命。該技術(shù)自從被發(fā)現(xiàn)以來,廣泛應(yīng)用于各種旋轉(zhuǎn)軸密封,例如各種波形油封、偏置O型圈、Kalsi密封等等,本課題主要結(jié)合成型旋轉(zhuǎn)動壓徑向密封機理及其結(jié)構(gòu)優(yōu)化設(shè)計方法研究這一研究項目,針對擠壓型旋轉(zhuǎn)軸密封的密封性能進行研究。本論文的研究內(nèi)容主要包括以下三個部分:首先對國內(nèi)外各種流體動壓技術(shù)進行了探究,研究了流體動壓技術(shù)的動壓效應(yīng)。通過結(jié)合軟彈性流體動壓潤滑的求解問題以及雷諾方程提出了求解流體動壓潤滑油膜的求解方法。其次結(jié)合kalsi密封,通過三維建模軟件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軟件ABAQUS對該密封進行仿真研究,分析具有不同正弦波形參數(shù)條件下密封唇的接觸應(yīng)力以及不同波形參數(shù)對密封性能的影響,并對普通波形密封的密封唇參數(shù)設(shè)計進行了理論設(shè)計。最后是試驗臺的設(shè)計,根據(jù)該密封實驗要求以及相關(guān)試驗臺設(shè)計標準確定了試驗臺的設(shè)計方案,借助于Solid Works進行三維建模,完成試驗臺樣機的開發(fā),并繪制了零件工程圖紙,完成了試驗臺的搭建。
[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.
