Of the two conical gear reducer design of functional deposition, the establishment of threedimensional parametric gear reducer and gear reducer design parts (the main transmission parts, standard parts, etc.) model library, the total assembly method of constructing the library. And with the inventor of virtual software and database technology, for two conical cylindrical gears threedimensional modeling of conical reducer cylindrical body position, the internal transmission parts, and assembly interference analysis, stress and strain analysis, spatial motion analysis, motion simulation, eventually to produce two dimensional drawings. Using inventor of virtual software products designed threedimensional modeling, assembly, motion simulation and engineering plans and other aspects of the production study found that stress and strain analysis in the CAD is an extremely important element. Only threedimensional design, be possible to set up the finite element analysis of raw data, and then to part geometry and the optimal shape. II Otherwise, the design is the traditional method: even the prototype for many of the bench test for the high cost, cycle length, is the modern market economy can not be tolerated. Starting from the threedimensional design, in support of existing software, this model may be expressed at least all the geometric parameters of the design concept, the whole design process can be fully discussed in the threedimensional model, it is easy to design the supporting rapid expansion of the whole process the design of all the processes can use a unified data, starting from the threedimensional design, the expression of twodimensional engineering drawings still have to ply with the requirements of traditional design. This oday, tomorrow our puter CAD. Key words: 3D virtual design。 threedimensional modeling。 reducer。 III 目 錄 引言 ??????????????????????????? ??? ? 1 1 概述 ???????????????????????????? 2 2 電機(jī)的選擇計(jì)算 ??????????????????????? 4 選擇電動(dòng)機(jī)的類型 ??????????????????????? 4 選擇電動(dòng)機(jī)的容量 ???????? ???????????????? 4 確定電動(dòng)機(jī)轉(zhuǎn)速 ????????????????????????? 4 計(jì)算傳動(dòng)裝置的總傳動(dòng) ????? 5 分配原則 ?????????????????????????? 5 總傳動(dòng)比 i∑ ????????????????????????? 5 分配傳動(dòng)比 ?????????????????????????? 5 計(jì)算傳動(dòng)裝置各軸的運(yùn)動(dòng)和動(dòng)力參數(shù) ??????????????? 5 各軸的轉(zhuǎn)速 ?????????????? ??????????? 5 各軸的輸入功率 ??????????????????????? 5 各軸的輸入轉(zhuǎn)矩 ??????????????????????? 6 3 傳動(dòng)零件的設(shè)計(jì)計(jì)算 ????????????????????? 6 閉式直齒輪圓錐齒輪傳動(dòng)的設(shè)計(jì)計(jì)算 ???????????????? 6 閉式直齒圓柱齒輪傳動(dòng)的設(shè)計(jì)計(jì)算 ????????????????? 9 軸的設(shè)計(jì)計(jì)算 ????????????????????????? 12 減速器高速軸Ⅰ的設(shè) 計(jì) ???????????????????? 12 減速器的低速軸Ⅱ的設(shè)計(jì) ??????????????????? 14 減速器低速軸Ⅲ的設(shè)計(jì)計(jì)算 ?????????????????? 16 4 滾動(dòng)軸承的選擇與壽命計(jì)算 ????????????????? 18 減速器高速 I 軸滾動(dòng)軸承的選擇與壽命計(jì)算 ???????????? 18 減速器低速 III 軸滾動(dòng)軸承的選擇與壽命計(jì)算 ??????????? 19 5 鍵聯(lián)接的選擇 ???????????????????????? 20 高速軸的鍵聯(lián)接 ???????????????????????? 20 低速軸的鍵連接 ???????????????????????? 20 6 減速器機(jī)體的結(jié)構(gòu)設(shè)計(jì) ??????????????????? ? 20 機(jī)體要具有足夠的剛度 ????????????????????? 20 6 . 2 機(jī) 體 的 結(jié) 構(gòu) 要 便 于 機(jī) 體 ? ? ? ? ? 21 機(jī)體結(jié)構(gòu)要具有很好的工藝性 ?????????????????? 22 確定機(jī)蓋大小齒輪一段的外輪廓半徑 ??????????????? 22 IV 7 潤滑和密封設(shè)計(jì) ???????????????????????? 22 潤滑 ???????????????????????????? ? 22 密封 ????????????????????????????? 23 8 箱體設(shè)計(jì)的主要尺寸及數(shù)據(jù) ????????????????? 23 9 三維建模 ??????????????????????????? 24 三維建模技術(shù) ????????????????????????? 24 草圖概念設(shè)計(jì) ???????????????????? ????? 25 零件的三維參數(shù)化設(shè)計(jì)建摸 ?????????????????? 25 虛擬裝配 ? ????????????????????????? 28 干涉分析 ? ????????????????????????? 30 應(yīng)力分析 ?????????????????????????? 30 10 結(jié)論 ???????????????????????????? 31 謝辭 ??????????????????????????????? 32 參考文獻(xiàn) ???????????? ???????????????? 33 桂林電子科技大學(xué)信息科技學(xué)院畢業(yè)設(shè)計(jì) (論文 )說明書 第 1 頁 共 34 頁 1 引言 本課題研究的目的是在已有減速器設(shè)計(jì)的基本理論基礎(chǔ)上,利用 Inventor 2021 三維設(shè)計(jì)軟件和數(shù)據(jù)庫技術(shù),建立齒輪、軸、軸承、上箱體及下箱體的三維參數(shù)模型,將各零件進(jìn)行裝配。 本課題研究的意義在于:能夠?yàn)辇X輪減速器是設(shè)計(jì)提供一種全新手段和方法,改變?cè)械氖止ぴO(shè)計(jì),二維設(shè)計(jì)變?yōu)槿S設(shè)計(jì),并在設(shè)計(jì)中體現(xiàn)引導(dǎo)作用,使設(shè)計(jì)更為直觀、形象、生動(dòng);通過實(shí)時(shí)人機(jī)互動(dòng)式的三維參數(shù)化實(shí)體造型設(shè)計(jì),更好地理解、掌握零部件的結(jié)構(gòu) 及裝配關(guān)系,實(shí)現(xiàn)齒輪建起的動(dòng)力學(xué)參數(shù)設(shè)計(jì)計(jì)算、齒輪傳動(dòng)設(shè)計(jì)技術(shù)、軸系的設(shè)計(jì)技術(shù);分析三維參數(shù)化設(shè)計(jì)的方法,運(yùn)用設(shè)計(jì)辯論與程序設(shè)計(jì)相結(jié)合的方法實(shí)現(xiàn)零件的三維參數(shù)化設(shè)計(jì),在此基礎(chǔ)上采用了在零件環(huán)境中以及在裝配環(huán)境中建立零件模板的兩天方法;分析齒輪減速 器總裝配及各部件之間的結(jié)構(gòu)尺寸約 的設(shè)計(jì)思想分別構(gòu)建減速器總裝裝配模板和軸系模板。采用 Inventor 2021 三維設(shè)計(jì)軟件,并結(jié)合 AutoCAD_2021 等二維繪圖軟件,設(shè)計(jì)了一個(gè)二級(jí)圓錐圓柱齒輪減速器,實(shí)現(xiàn)了減速器的三維模型生產(chǎn),以及由此生成二維工程圖的思想。通過 Inventor 2021三維設(shè)計(jì)軟件特有的 干涉分析、應(yīng)力應(yīng)變分析、空間運(yùn)動(dòng)分析、 運(yùn)動(dòng)仿真功能,對(duì)減速器進(jìn)行了檢查和優(yōu)化設(shè)計(jì)方案,實(shí)現(xiàn)減速器的運(yùn)動(dòng)仿真,完成了減速器在計(jì)算機(jī)中虛擬設(shè)計(jì)。 1 概述 桂林電子科技大學(xué)信息科技學(xué)院畢業(yè)設(shè)計(jì) (論文 )說明書 第 2 頁 共 34 頁 2 隨著現(xiàn)代工業(yè)的不斷發(fā)展和擴(kuò)大,對(duì)工業(yè)機(jī)械的需求量也再迅速的增加,同時(shí)對(duì)機(jī)械設(shè)備的可靠性,維修性,安
