【摘要】：中國(guó)風(fēng)能資源豐富,開發(fā)潛力巨大,必將成為未來能源結(jié)構(gòu)中一個(gè)重要的組成部分。我國(guó)大型風(fēng)力發(fā)電機(jī)制造業(yè)基本從零起步,目前已經(jīng)掌握了750KW至6MW的風(fēng)電齒輪箱零部件的設(shè)計(jì)制造技術(shù),并實(shí)現(xiàn)了批量生產(chǎn)。但總的來說,關(guān)鍵零部件設(shè)計(jì)制造技術(shù)仍是我國(guó)風(fēng)機(jī)制造業(yè)長(zhǎng)期發(fā)展的最大瓶頸。從設(shè)計(jì)到制造還依賴國(guó)外技術(shù),沒有完全擺脫引進(jìn)、模仿、再引進(jìn)、再模仿的模式。 風(fēng)電齒輪箱是一種重載、低速、增速齒輪傳動(dòng)裝置,其工作的條件是無規(guī)律變向風(fēng)力作用及強(qiáng)陣風(fēng)沖擊的變載荷,在工作過程中,系統(tǒng)受力情況復(fù)雜。對(duì)風(fēng)電齒輪箱力和變形情況進(jìn)行研究有助于改進(jìn)設(shè)計(jì),從設(shè)計(jì)的角度降低振動(dòng),保證其設(shè)計(jì)壽命和系統(tǒng)的可靠性,對(duì)我國(guó)風(fēng)電技術(shù)發(fā)展有著重要的意義。在國(guó)外,進(jìn)入風(fēng)電場(chǎng)的風(fēng)電機(jī)組必須通過認(rèn)證。在認(rèn)證的發(fā)展和應(yīng)用領(lǐng)域一直處于領(lǐng)先地位的歐洲國(guó)家,例如德國(guó)、丹麥和荷蘭,由于其技術(shù)在世界上一直處于領(lǐng)先的水平,其認(rèn)證體系也是最完善的。本文主要是為了使齒輪箱通過德國(guó)船級(jí)社風(fēng)電齒輪箱認(rèn)證體系,做的一項(xiàng)必不可少的行星齒輪均載測(cè)試,以驗(yàn)證風(fēng)電齒輪箱行星機(jī)構(gòu)的設(shè)計(jì)是否滿足設(shè)計(jì)要求。 在本論文研究中,主要展開了如下工作： 介紹了GL認(rèn)證相關(guān)的技術(shù)要求,研究了測(cè)試加載系統(tǒng)的原理以及測(cè)試加載系統(tǒng)的建立。 完成了滿足GL風(fēng)量齒輪箱認(rèn)證要求的一級(jí)齒圈應(yīng)變測(cè)試方案的制定,以及應(yīng)變片的粘貼、齒輪箱箱體內(nèi)部的布線。研究確定了GL要求測(cè)量的相關(guān)量計(jì)算原理及計(jì)算的方法。 通過不同載荷情況下行星傳動(dòng)試驗(yàn)及試驗(yàn)數(shù)據(jù)的分析處理,得出實(shí)際的均載效果和工程設(shè)計(jì)用的試驗(yàn)數(shù)據(jù)。 總之,通過研究,基本掌握了滿足GL認(rèn)證要求的應(yīng)變測(cè)試方法,以及相應(yīng)的數(shù)據(jù)分析處理方法。不僅提高了專業(yè)技術(shù)水平,而且對(duì)今后企業(yè)行星齒輪的設(shè)計(jì)和加工將有大的指導(dǎo)；對(duì)提升行星齒輪產(chǎn)品綜合性能指標(biāo)、齒輪箱的產(chǎn)品質(zhì)量及以后更加深入的研究都有一定的參考價(jià)值和意義。
[Abstract]:China is rich in wind energy resources and has great potential for development, which will become an important part of the energy structure in the future. China's large-scale wind turbine manufacturing industry basically starts from scratch. At present, we have mastered the design and manufacturing technology of 750KW to 6MW wind power gearbox components, and have realized batch production. But in general, The design and manufacturing technology of key parts is still the biggest bottleneck in the long-term development of fan manufacturing industry in our country. From design to manufacture, we still rely on foreign technology, without completely getting rid of the mode of importing, imitating, reintroducing and imitating. The gearbox of wind power is a kind of gear transmission with heavy load, low speed and high speed. The working conditions of the gearbox are irregular wind force and variable load caused by strong gusts. The study of the force and deformation of the wind power gearbox will help to improve the design, reduce the vibration from the design point of view, ensure the design life and the reliability of the system. It is of great significance to the development of wind power technology in China. In foreign countries, wind turbines entering wind farms must pass the certification. European countries, such as Germany, Denmark and the Netherlands, have always been in the leading position in the field of development and application of the certification. Since its technology has always been in the leading level in the world, its certification system is also the most perfect. This paper is mainly to make the gearbox pass the German Classification Society wind power gearbox certification system, do an indispensable planetary gear load test. To verify that the design of the planetary mechanism of wind power gearbox meets the design requirements. In this thesis, the main work is as follows:. This paper introduces the technical requirements of GL authentication, studies the principle of test loading system and the establishment of test loading system. The first grade gear ring strain test scheme which meets the requirements of GL air volume gearbox certification is made, the strain gauge is pasted, and the inner wiring of the gearbox box is arranged. The calculation principle and calculation method of the relevant quantity required by GL are studied and determined. Through the analysis and processing of the planetary transmission test and test data under different loads, the actual average load effect and the test data for engineering design are obtained. In a word, through the research, we have mastered the strain testing method which meets the requirements of GL certification, and the corresponding data analysis and processing methods, which not only improve the professional technical level, Moreover, it will have great guidance for the design and processing of planetary gears in enterprises in the future, and will have certain reference value and significance for improving the comprehensive performance index of planetary gear products, the product quality of gearbox and the further research in the future.
