3775 油茶墾復(fù)機(jī)中間傳動系統(tǒng)的設(shè)計,油茶,墾復(fù),中間,傳動系統(tǒng),設(shè)計 IJIANGXI AGRICULTURAL UNIVERSITY本 科 畢 業(yè) 論 文（設(shè) 計）題目： 油茶墾復(fù)機(jī)中間傳動系統(tǒng)的設(shè)計 學(xué) 院： 工 學(xué) 院 姓 名： 彭 星 亮 學(xué) 號： 20080945 專 業(yè)： 機(jī)械設(shè)計制造及其自動化 年 級： 機(jī)制 081 指導(dǎo)教師： 饒洪輝 職 稱： 講師 二 0 一二 年 五 月II摘 要歷年來的豐產(chǎn)經(jīng)驗證明：抓緊夏季墾復(fù)荒山，加強熟山中耕培育，是保證全面油茶大豐收的主要關(guān)鍵。油茶地經(jīng)墾復(fù)后土壤疏松,保水保肥,促進(jìn)茶株根系發(fā)育,春季所發(fā)新梢數(shù)、梢長、新葉數(shù)、花芽數(shù)分別比不墾復(fù)的增加48.5%、118.7%、11.5%和 88 ? 7%,而且茶籽千粒重增加 0.7 一 3.3 公斤,畝產(chǎn)量增加 11.7 一 39.2 公斤,增產(chǎn) 15.7%一 81.6%。所謂的墾復(fù)是指翻耕荒蕪的茶山而言，其目的在于：消除雜草灌木，促進(jìn)土壤風(fēng)化，故宜用深挖。墾復(fù)的深度視情況而定，一般７～８寸。本課題運用制圖軟件對油茶墾復(fù)機(jī)中間傳動進(jìn)行機(jī)構(gòu)設(shè)計，其中包括中間傳動，側(cè)邊的傳動，旋轉(zhuǎn)鍬的設(shè)計。通過蝸輪蝸桿的變向?qū)恿鞯絺?cè)邊，使用大小齒輪實現(xiàn)減速后傳給刀，既解決了側(cè)邊傳動耕幅較小的問題，也實現(xiàn)了低速、高效率的墾復(fù)要求。關(guān)鍵字：油茶，墾復(fù)機(jī)，中間傳動，設(shè)計IIIAbstractOver the years the high yield experience proves: hold summer cultivation of barren mountain, strengthen cultivation cultivation is to ensure that the cooked hill, comprehensive bumper harvest of Camellia tea. Camellia tea by reclamation after loose soil, fertilizer and water conservation, the promotion of tea plant root development, spring hair shoot number, shoot length, leaf number, new flower bud number were less than48.5%,118.7% increase in the county,88,11.5% and7%, and the tea seed weight increased by 0.73.3kg, yield increase11.739.2 kilograms, increase production 15.7%81.6%. The so-called reclamation is plowed barren mountain, its purpose is: to eliminate weeds shrubs, to promote soil weathering, therefore suitable for deep. Reclamation of depth depending on the situation, general 7 ~8 inch. The subject of the use of mapping software on Camellia tea cultivating machine intermediate transmission mechanism design, including the intermediate drive, side drive, rotary shovel design. Through the worm gear turning to power side, using the size gear speed reducing unit to the cutter, which solves the side driving the tilling amplitude is smaller, but also to achieve a low, efficient reclamation requirements.Keywords: tea, cultivating machine, an intermediate transmission, designIV目錄１ 緒　 論 ..............................................................................................................................11.1 　 引 言 ...........................................................................................................................11.2　 油茶墾復(fù)的簡介 .........................................................................................................1２油茶墾復(fù)機(jī)的工作原理 ......................................................................................................22.1　 油茶墾復(fù)機(jī)的工作方式 ..............................................22.2　 油茶墾復(fù)機(jī)傳動的選擇 ..............................................22.3　 油茶墾復(fù)機(jī)的耕作機(jī)具的選擇 ........................................22.4 油茶墾復(fù)機(jī)的工作原理的總圖 ........................................32.4.1 油茶墾復(fù)機(jī)工作原理簡述 .........................................32.4.2 油茶墾復(fù)機(jī)的三維裝配圖 .........................................42.4.3　 油茶墾復(fù)機(jī)的傳動機(jī)構(gòu)的二維圖 ..................................52.5 油茶墾復(fù)機(jī)的耕作機(jī)具 ...............................................62.5.1 旋耕刀的部分原理圖 .............................................62.5.2 旋耕刀的部分原理說明 ...........................................63 油茶墾復(fù)機(jī)中間傳動的設(shè)計 ...............................................73.1 傳動機(jī)構(gòu)的設(shè)計 ............................................................................................................73.1.1 中間傳動機(jī)構(gòu)簡圖 .................................................................................................73.1.2 中間傳動系統(tǒng)部分的原理簡述 .............................................................................73.1.3 旋耕鍬的技術(shù)參數(shù) .................................................................................................73.2 傳動比的確定 ................................................................................................................83.3 齒輪的設(shè)計 ....................................................................................................................83.3.1 錐齒輪的基本幾何尺寸 .........................................................................................83.3.2 直齒圓柱齒輪的的設(shè)計 .........................................................................................83.4 傳動軸的設(shè)計 .............................................................................................................113.4.2 初步計算軸上各段長度 ....................................................................................113.4.3 軸的結(jié)構(gòu)設(shè)計： ................................................................................................113.4.4.繪制軸的彎扭矩圖，對危險截面進(jìn)行校核 .......................................................123.5 軸承的校核 .................................................................................................................143.5.1 計算軸承的當(dāng)量動載荷 P： ...............................................................................143.5.2 校核計算 ..............................................................................................................143.5.3 軸上鍵連接的選擇及校核 ................................................................................153.5.4 軸上螺母的選擇 ...................................................................................................153.6 懸掛機(jī)構(gòu)的設(shè)計 ..........................................................................................................163.7 耕作機(jī)具的設(shè)計 .........................................................................................................18４總結(jié) ..................................................................19參 考 文 獻(xiàn) .............................................................20致謝 ....................................................................21
