【摘要】：齒輪泵是應(yīng)用最廣泛的容積式液體輸送泵，具有尺寸小、重量輕、制造容易、工作可靠、價(jià)格低廉、對(duì)油液不敏感、自吸能力強(qiáng)、維護(hù)方便等優(yōu)點(diǎn)。但它的輸出脈動(dòng)明顯、困油嚴(yán)重、排量小，限制了其應(yīng)用場(chǎng)合。為了擴(kuò)大齒輪泵應(yīng)用范圍，本文以齒輪嚙合理論為基礎(chǔ)提出了一種新型結(jié)構(gòu)的齒輪泵。 新型齒輪泵對(duì)普通齒輪泵的結(jié)構(gòu)做了必要的改造，通過把兩種不同模數(shù)的齒形組合在一起，，將運(yùn)動(dòng)、動(dòng)力傳遞功能與工作容積變化功能基本分離。分離后，排量增大為同等體積條件下普通直齒輪泵的2倍以上，而困油程度有明顯減輕。在新產(chǎn)品的設(shè)計(jì)過程中，詳細(xì)研究了齒輪泵的流量特性。推導(dǎo)了計(jì)算瞬時(shí)流量、流量脈動(dòng)的計(jì)算公式，深入研究了齒輪泵的困油現(xiàn)象，推導(dǎo)出了計(jì)算齒輪泵困油容積變化量的計(jì)算公式；并應(yīng)用Pro/ENGINEER軟件參數(shù)化建模的功能，對(duì)齒輪齒形進(jìn)行精確繪制，建立了齒輪泵的參數(shù)化仿真模型；應(yīng)用ADAMS軟件進(jìn)行了運(yùn)動(dòng)學(xué)及動(dòng)力學(xué)仿真驗(yàn)證了齒輪泵傳動(dòng)系統(tǒng)模型的正確性；采用ANSYS有限元法對(duì)齒輪泵齒輪的結(jié)構(gòu)和受力進(jìn)行分析；為了捕捉大流量齒輪泵的內(nèi)部流場(chǎng)變化，對(duì)大流量齒輪泵的流場(chǎng)進(jìn)行了仿真研究，利用Fluent軟件的動(dòng)網(wǎng)格技術(shù)對(duì)同步齒輪泵的二維簡(jiǎn)化模型進(jìn)行了流場(chǎng)仿真，為新型齒輪泵的三維流場(chǎng)仿真分析奠定了基礎(chǔ)，為基于動(dòng)網(wǎng)格的齒輪泵內(nèi)部流場(chǎng)模擬走向?qū)嵺`奠定基礎(chǔ)。
[Abstract]:The gear pump is the most widely used volumetric liquid pump, with small size, light weight, easy manufacture, reliable operation, low price, not sensitive to oil, self-priming ability, convenient maintenance and so on. But its output pulsation is obvious, trapped oil seriously, small displacement, limit its application in order to expand the scope of application occasions. The gear pump gear pump is proposed in this paper, a new structure based on the meshing theory of gears.
The structure model of ordinary gear pump gear pump to do the necessary transformation, through the combination of two kinds of teeth with different modulus together, will exercise the power transfer function and the volume of work function changes the basic separation. After separation, the same displacement increases under the condition that the volume of ordinary straight gear pump more than 2 times, and trapped oil the degree of significant loss. In the process of new product design, with the flow characteristics of gear pump is studied. Calculation of instantaneous flow is deduced. The calculation formula of flow pulsation, in-depth study of the phenomenon of trapped oil gear pump, deduced the calculation formula of gear pump trapped oil volume; and using Pro/ENGINEER software modeling of gear tooth function, accurate rendering, established the parameterized simulation model of gear pump; application of ADAMS software to simulate the kinematics and dynamics simulation of transmission system of gear pump model The correctness of the ANSYS finite element method; structure of the gear pump and force analysis; in order to capture changes in internal flow field of high flow gear pump, the flow field of high flow gear pump was simulated. The simplified model of two dimensions of the synchronization gear pump to simulate the flow field using the dynamic grid technology of Fluent software. The foundation for three-dimensional flow field simulation analysis model of gear pump, gear pump for internal flow field based on dynamic mesh simulation to lay the foundation for practice.
