【摘要】：蝸桿傳動(dòng)是重要的齒輪傳動(dòng)類型之一,具有傳動(dòng)比大、結(jié)構(gòu)緊湊等優(yōu)點(diǎn),廣泛應(yīng)用在礦山、冶金、起重運(yùn)輸和國(guó)防等行業(yè)。傳統(tǒng)的蝸輪蝸桿的損壞主要都是因?yàn)闈?rùn)滑狀態(tài)過(guò)于惡劣而使蝸輪磨損。本文以傳統(tǒng)的ZA蝸桿傳動(dòng)副為研究對(duì)象,通過(guò)對(duì)其腹板位置的整體結(jié)構(gòu)設(shè)計(jì)而使輪齒產(chǎn)生形變,進(jìn)而形成流體動(dòng)壓潤(rùn)滑,以此來(lái)改善蝸輪磨損嚴(yán)重的情況。本文主要完成了如下工作： 1.對(duì)ZA蝸桿、蝸輪的齒面方程的數(shù)學(xué)模型進(jìn)行了比較系統(tǒng)的整理,并在原數(shù)學(xué)模型的基礎(chǔ)上根據(jù)建模需要對(duì)蝸輪輪齒的數(shù)學(xué)表達(dá)式進(jìn)行了推導(dǎo),以此作為建立ZA蝸桿傳動(dòng)模型的理論基礎(chǔ)。 2.本文通過(guò)對(duì)ZA蝸輪蝸桿齒面方程的研究,在Pro/E中建立了ZA蝸輪蝸桿的實(shí)體模型。針對(duì)原蝸桿傳動(dòng)不易形成油膜的問(wèn)題,對(duì)蝸輪的腹板位置進(jìn)行適當(dāng)偏移,并建立三維模型,為靜力分析及流體分析做準(zhǔn)備。 3.對(duì)在Workbench環(huán)境下的前處理過(guò)程進(jìn)行了較為詳細(xì)的敘述,分析了ZA蝸桿傳動(dòng)在同一嚙合位置施加負(fù)載情況下的接觸應(yīng)力與變形情況。然后對(duì)整體設(shè)計(jì)之后的蝸輪也進(jìn)行了相同負(fù)載條件下的靜力分析,并對(duì)兩者結(jié)果進(jìn)行比較,分析蝸輪結(jié)構(gòu)設(shè)計(jì)后是否有利于流體動(dòng)壓潤(rùn)滑油膜的形成。 4.根據(jù)流體動(dòng)壓理論結(jié)合實(shí)際的蝸桿傳動(dòng),考慮到傳動(dòng)過(guò)程中流體受力與蝸輪的形變量有關(guān),對(duì)油膜模型進(jìn)行了適當(dāng)?shù)暮?jiǎn)化處理,采用FLUENT的計(jì)算機(jī)模擬仿真,為蝸輪蝸桿的流體動(dòng)壓潤(rùn)滑模擬提供了一種較為有效的仿真方法。
[Abstract]:Worm gear transmission is one of the important gear transmission types, with the advantages of high transmission ratio and compact structure. It is widely used in mining, metallurgy, lifting transportation and national defense industries. The damage of the traditional worm gear is mainly caused by the wear and tear of the worm gear due to the poor lubrication condition. In this paper, the traditional Za worm transmission pair is taken as the research object. The gear teeth are deformed by the overall structural design of its web position, and then hydrodynamic lubrication is formed to improve the serious wear of worm gear. The main work of this paper is as follows: 1. The mathematical model of the tooth surface equation of Za worm and worm gear is systematically arranged, and the mathematical expression of the worm gear tooth is deduced according to the need of modeling on the basis of the original mathematical model. It is used as the theoretical basis of establishing Za worm transmission model. 2. In this paper, through the study of the equation of the tooth surface of Za worm gear, the solid model of Za worm gear is established in Pro/E. Aiming at the problem that oil film is not easy to be formed in the original worm drive, the web plate position of the worm gear is shifted appropriately, and a three-dimensional model is established to prepare for static analysis and fluid analysis. 3. The preprocessing process in Workbench environment is described in detail, and the contact stress and deformation of Za worm drive under the same meshing position are analyzed. Then the static analysis of the wormgear after the whole design is carried out under the same load condition, and the results are compared to analyze whether the structure design of the worm gear is favorable to the formation of the hydrodynamic lubricating oil film after the structural design of the worm wheel. 4. According to the hydrodynamic pressure theory combined with the actual worm drive, considering that the fluid force in the transmission process is related to the shape variable of the worm gear, the oil film model is properly simplified and the computer simulation of FLUENT is adopted. A more effective simulation method is provided for the hydrodynamic lubrication simulation of worm gear and worm.
