To reduce the original motivation to Speed or torque, in order to meet the needs of working machine. The speed reducer has the advantages of pact structure, high transmission efficiency Accurate and reliable transmission, convenient maintenance, so in the industrial and mining enterprises and transportation, the use of building industry Very broad. This paper starting from the mechanical design, in order to focus on accurate modeling 3D reducer, introduces in detail Sketch function, feature modeling function of UnigraphicsNX, the basic threedimensional modeling process, introduce in fact The assembly function. UG as a leader of a CAD\/CAM\/CAE design software, it includes some of the world39。s Product design application module of the most powerful, the most extensive, with high performance of the mechanical design and drawing function, for the preparation of Provides high performance and flexibility of design, to meet customer needs any plex product design. Master The use of its basic function, professional mechanical design for our students has a very good effect. ANSYS software is a large general finite element analysis software, a modeling function of processor of ANSYS ， But the establishment of gear tooth profile precision in ANSYS software in the more difficult. This paper is the application of UG Software to draw gear, the finite element analysis software ANSYS, gear reducer in ANSYS Finite element analysis of the ponents。 Keywords reducer UnigraphicsNX , UG , finite element , analysis , ANSYS 目 錄 中文摘要 ..................................................................Ⅰ 英 文 摘要 ..................................................................Ⅱ I 1 概述 .................................................................. 1 帶式運(yùn)輸機(jī) ......................................................... 1 使用情況 ....................................................... 1 帶傳動要求 .................................................... 1 滾筒的要求 ..................................................... 1 變速器的要求 .............................................1 設(shè)計(jì)條件 .....................................................1 已知條件 .................................................1 2 減速器的設(shè)計(jì)計(jì)算 .............................................2 電機(jī)選擇與傳動比計(jì)算 ......................................2 電動機(jī)類型的選擇 .........................................2 電機(jī)功率的計(jì)算與型號確定 ................................2 運(yùn)動和動力參數(shù)計(jì)算 .........................................3 傳動比分配 ...............................................3 傳動零件的設(shè)計(jì)計(jì)算和結(jié)構(gòu)設(shè)計(jì) .............................5 帶傳動設(shè)計(jì)計(jì) ............................................5 高速級齒輪設(shè)傳動計(jì)計(jì)算 .................................7 低速級齒輪傳動設(shè)計(jì)計(jì)算 ...................................11 低速級齒輪傳動設(shè)計(jì)計(jì)算 ................................15 軸的結(jié)構(gòu)設(shè)計(jì) ...............................................19 高速軸的設(shè)計(jì) ............................................19 中間 軸的設(shè)計(jì) ...........................................22 低速軸的設(shè)計(jì) ...........................................27 軸承的選擇與校核 .........................................33 鍵的選取 ....................................................33 減速器的潤滑和密封 .......................................34 齒輪的潤滑 .......................................... 34 滾動軸承的潤滑 ............................................35 箱體及其附件設(shè)計(jì) .........................................35 箱體尺寸 ............................................ 35 起吊裝置 ............................................. 36 窺視孔窺視蓋 ........................................ 36 放油孔和螺塞 ......................................... 36 3 基于 UG 二級斜齒輪減速器三維造型 ..........................37 ug 軟件介紹 .................................................37 箱蓋的三維造型 .............................................38 箱座的三維造型 .............................................47 斜齒輪和標(biāo)準(zhǔn)件三維造型設(shè)計(jì) ...............................55 4 減速器的虛擬裝配 ..............................................57 中間軸的裝配 ...............................................57 輸出軸的裝配 ...............................................58 輸入軸的裝配 ...............................................59 軸和軸承端改的裝配 ........................................60 箱蓋的裝配 ..................................................60 標(biāo)準(zhǔn)件的裝配 ................................................61 5 減速器的運(yùn)動仿真 ............................................62 定義減速器的連桿 ..........................................62 建立連桿副 .................................................64 建立齒輪副 .................................................64 設(shè)置解算方案和求解 ........................................65 6 ansys 對減速器零部件的靜力學(xué)分析 .....................
