【摘要】：隨著我國(guó)工業(yè)的不斷發(fā)展,齒輪傳動(dòng)在工業(yè)生產(chǎn)中發(fā)揮的作用越來(lái)越大,提前預(yù)測(cè)出齒輪異常磨損顯得越來(lái)越重要。盡管?chē)?guó)內(nèi)齒輪磨損檢測(cè)方法多種多樣,但是用于預(yù)測(cè)齒輪異常磨損的并不多,且很少涉及到用齒輪磨損率檢測(cè)齒輪磨損狀態(tài)。本文利用上位機(jī)LabVIEW開(kāi)發(fā)一種基于變化率形式檢測(cè)浸油齒輪磨損率的在線監(jiān)測(cè)系統(tǒng),該系統(tǒng)能夠?qū)崟r(shí)連續(xù)的采集齒輪箱油液中鐵磁性顆粒尺寸大小和油液品質(zhì)數(shù),通過(guò)上、下位機(jī)工作模式,實(shí)現(xiàn)了齒輪磨損的實(shí)時(shí)監(jiān)測(cè)和提前預(yù)測(cè),且系統(tǒng)結(jié)合了總值方式監(jiān)測(cè)齒輪磨損狀況的優(yōu)點(diǎn),增強(qiáng)了判別齒輪異常磨損的準(zhǔn)確性以及判別效率。首先,為提高油液磨粒的檢測(cè)范圍,設(shè)計(jì)了一款新結(jié)構(gòu)的磨粒傳感器,并提供設(shè)計(jì)理論。通過(guò)對(duì)比仿真驗(yàn)證,證實(shí)了設(shè)計(jì)磨粒傳感器確實(shí)能提高磨粒檢測(cè)范圍,并建立了磨粒尺寸與信號(hào)輸出之間的關(guān)系。其次,根據(jù)設(shè)計(jì)傳感器的輸出信號(hào)設(shè)計(jì)了磨粒檢測(cè)電路,并搭建了嵌入式硬件平臺(tái),完成了磨粒信息與潤(rùn)滑油品質(zhì)信息的處理。根據(jù)變化率理論,搭建嵌入式軟件開(kāi)發(fā)平臺(tái),實(shí)現(xiàn)了齒輪磨損率的監(jiān)測(cè),并開(kāi)發(fā)上位機(jī)監(jiān)測(cè)中心,實(shí)現(xiàn)了齒輪磨損的實(shí)時(shí)監(jiān)測(cè)。最后,對(duì)設(shè)計(jì)的硬件電路進(jìn)行電路測(cè)試,證實(shí)設(shè)計(jì)電路的可行性。通過(guò)對(duì)設(shè)計(jì)系統(tǒng)的系統(tǒng)測(cè)試以及實(shí)驗(yàn),證實(shí)了設(shè)計(jì)系統(tǒng)能夠提前預(yù)測(cè)齒輪異常磨損,并證實(shí)了以變化率形式結(jié)合總值方式監(jiān)測(cè)齒輪異常磨損,能提高判別齒輪異常磨損的準(zhǔn)確性以及判別效率。設(shè)計(jì)系統(tǒng)達(dá)到了預(yù)期目標(biāo)。
[Abstract]:With the development of industry, more and play the function of gear transmission in the industrial production of the larger, predict abnormal wear of gear is becoming more and more important. Although the domestic gear wear various detection methods, but for the prediction of abnormal wear of gear is not much, and rarely involve the gear wear rate detection gear wear condition. In this paper, the use of PC LabVIEW to develop a online monitoring system for the rate of change of form of gear wear rate based on the detection of oil, the system can collect real-time continuous gearbox oil liquid iron magnetic particle size and oil quality, the lower machine, working mode, to achieve real-time monitoring of the gear wear and predict in advance, and the system combines the advantages of the gross way of monitoring gear wear condition, enhances the accuracy and efficiency of the identification of abnormal wear of gear. First of all, in order to improve the oil The detection range of liquid abrasive particles, abrasive designed a new sensor structure, and provides the design theory. By comparing the simulation results confirmed that the design of abrasive abrasive sensor can improve the detection range, and establishes the relationship between the grain size and the signal output. Secondly, according to the design of the sensor output signal the design of particle detection circuit, and an embedded hardware platform, complete the processing of debris and oil quality information. According to the rate of change of theory, build the embedded software development platform, to achieve the monitoring of gear wear rate, and the development of the PC monitoring center, to achieve real-time monitoring of the gear wear. Finally, for the circuit test of hardware circuit design, circuit design feasibility. Based on the system design system testing and experiment, confirmed that the design system can predict abnormal wear of gear, and confirmed The abnormal wear rate of gear is monitored by changing rate form and total value. It can improve the accuracy and efficiency of judging the abnormal wear of gears. The design system has achieved the expected goal.
