【摘要】：作為機(jī)械傳動(dòng)的主要傳動(dòng)形式,齒輪傳動(dòng)已經(jīng)普遍應(yīng)用于機(jī)械工業(yè)中,是衡量工業(yè)技術(shù)水平發(fā)展的重要指標(biāo)。齒輪強(qiáng)度計(jì)算主要包括：接觸強(qiáng)度、彎曲強(qiáng)度和膠合強(qiáng)度。為防止齒面疲勞點(diǎn)蝕,需要進(jìn)行接觸強(qiáng)度的計(jì)算；防止齒根疲勞折斷,要進(jìn)行彎曲強(qiáng)度的計(jì)算；防止齒面膠合,需要進(jìn)行膠合計(jì)算。齒根折斷和齒面疲勞點(diǎn)蝕都有壽命期限,超載后會(huì)降低壽命,一般不會(huì)立即發(fā)生破壞,可以通過同循環(huán)次數(shù)相關(guān)的疲勞極限應(yīng)力加以控制。但是齒面膠合失效則不然,齒面膠合破壞的出現(xiàn)與時(shí)間無關(guān),只要在短時(shí)間的超載、溫升過高或者潤滑不當(dāng)?shù)那闆r下,膠合就可能發(fā)生。由于齒面膠合失效形式是突發(fā)性的,并且不易防范和察覺,膠合失效具有更大的危險(xiǎn)性。因此,建立一個(gè)合適的齒輪抗膠合承載能力計(jì)算方法是至關(guān)重要的,對(duì)創(chuàng)建一個(gè)完善的齒輪強(qiáng)度系統(tǒng)設(shè)計(jì)也是尤為重要的。 由于齒輪強(qiáng)度系統(tǒng)設(shè)計(jì)過程相當(dāng)復(fù)雜,需要查閱大量資料,并且還要進(jìn)行反復(fù)的計(jì)算和校核。因此,利用計(jì)算機(jī)技術(shù)進(jìn)行齒輪設(shè)計(jì),是一種勢不可擋的趨勢。 本課題主要的研究工作包括：根據(jù)閃溫法原理和齒輪傳動(dòng)極壓潤滑條件下的摩擦因數(shù),依據(jù)工業(yè)閉式齒輪潤滑油選用方法的標(biāo)準(zhǔn)和FZG標(biāo)準(zhǔn),推導(dǎo)了圓柱齒輪抗膠合承載能力接觸應(yīng)力的計(jì)算方法；依據(jù)齒輪強(qiáng)度計(jì)算方法,在Visual C++集成環(huán)境下,采用MFC框架技術(shù),開發(fā)齒輪的可視化設(shè)計(jì)軟件；對(duì)于設(shè)計(jì)過程中所涉及的圖、表,分別采用了MATLAB與VC++混合編程技術(shù)與ADO數(shù)據(jù)庫技術(shù)的處理方法,實(shí)現(xiàn)了自動(dòng)化查詢與調(diào)用圖、表中的有關(guān)數(shù)據(jù)。
[Abstract]:As the main forms of mechanical drive, gear drive has been widely used in machinery industry, is an important indicator to measure the level of industrial technology development. The gear strength calculation including contact strength, bending strength and bonding strength. In order to prevent tooth surface fatigue pitting, we need to compute the contact strength; prevent tooth root fatigue fracture, calculation bending strength; prevent tooth bonding, need for bonding calculation. The tooth root fracture and tooth surface pitting are life, overload will reduce the life, generally not immediately destroyed, but by the same number of cycles of fatigue limit stress related to control. But the tooth face scuffing or tooth surface the emergence of scuffing failure has nothing to do with time, as long as the short time overload, high temperature or improper lubrication under the condition of bonding may occur. Because the tooth face scuffing The form is unexpected, and it is not easy to prevent and detect. The failure of bonding is more dangerous. Therefore, it is very important to establish a suitable calculation method for the gear anti gluing capacity. It is also very important for creating a perfect gear strength system design.
Because the design process of gear strength system is quite complex, we need to consult a lot of data and carry out repeated computation and verification. Therefore, it is an irresistible trend to design gear with computer technology.
The main work of this research include: according to the principle of gear transmission and flash temperature extreme pressure coefficient of friction lubrication conditions, on the basis of industrial closed gear oil selection method and FZG standard, deduces the calculation method of load-carrying capacity of contact stress of cylindrical gears; calculation method based on the gear strength in Visual C++ the integrated environment, using the MFC framework technology, visualization software design of gear; involved in the design process of the graph, table, the processing method of MATLAB and VC++ mixed programming technology and ADO database technology, automatic query and call graph is realized, the data in the table.
