Involute planetary gear transmission has the following advantages: large transmission ratio, compact structure, small volume, small mass, high efficiency, low noise, smooth operation, so it is widely used in metallurgy, engineering machinery, lifting, transportation, aviation, machine tools, electrical machinery and defense industry and other departments, as gear reducer, gear or the growthThe transmission principle of NGW type planetary gear transmission mechanism: when the high-speed shaft driven by a motor, to drive the sun gear, and the planet wheel is driven to rotate, the inner gear ring is fixed, and then drives the planetary frame outputting motion, on the planet carrier planet wheel both rotation and revolution, has the same structure. The two level, three level or multilevel transmission. The NGW type planetary gear transmission mechanism mainly consists of a sun gear, planet gear, inner gear ring, a planetary frame, named after the basic components, also known as the ZK-H type planetary gear transmission mechanism.This design is the design of planetary gear structure based on SolidWorks, and 3D modeling and motion simulation. Comparison of characteristics of planetary gears, and various types of determination scheme; secondly according to the input power, the output speed of the overall design, transmission design, ratio; 3D modeling and finished SolidWorks, assembly and model, and the motion simulation and motion analysis of the transmission part.Keywords: planetary gear reducer, assembly, motion simulation, 3D modeling目 錄摘 要 .1Abstract.2第 1 章 緒論 51.1 國(guó)內(nèi)外的研究狀況及其發(fā)展方向 51.2 SOLIDWORKS 行星齒輪的選題分析及設(shè)計(jì)內(nèi)容 61.3 主要的工作內(nèi)容 6第 2 章 NGW 型行星輪減速器方案確定 82.1 機(jī)構(gòu)簡(jiǎn)圖的確定 82.2 周轉(zhuǎn)輪系部分的選擇 82.3 NGW 型行星輪減速器方案確定 .82.4 行星輪系中各輪齒數(shù)的確定 11第 3 章 NGW 型行星減速器結(jié)構(gòu)設(shè)計(jì) .133.1 基本參數(shù)要求與選擇 133.1.1 基本參數(shù)要求 .133.1.2 電動(dòng)機(jī)的選擇 .133.2 方案設(shè)計(jì) 133.2.1 機(jī)構(gòu)簡(jiǎn)圖 .133.2.2 齒形及精度 .143.2.3 齒輪材料及性能 .143.3 齒輪的計(jì)算與校核 153.3.1 配齒數(shù) .153.3.2 初步計(jì)算齒輪主要參數(shù) .153.3.3 按彎強(qiáng)度曲初算模數(shù) m 183.3.4 齒輪疲勞強(qiáng)度校核 .193.4 軸上部件的設(shè)計(jì)計(jì)算與校核 253.4.1 軸的計(jì)算 .253.4.2 行星架設(shè)計(jì) .303.5 鍵的選擇與校核 343.5.1 鍵的選擇 .343.5.2 鍵的校核 .353.6 聯(lián)軸器的選擇 363.7 箱體尺寸及附件的設(shè)計(jì) 37第 4 章 SOLIDWORKS 的建模與運(yùn)動(dòng)仿真 424.1 建模軟件的介紹 424.2 行星齒輪機(jī)構(gòu)的建模 424.2.1 對(duì)行星齒輪的建模 .424.2.2 行星齒輪其他部件的建模 .444.3 行星齒輪機(jī)構(gòu)的虛擬裝配 464.4 裝配體的實(shí)現(xiàn) 574.5 減速機(jī)的運(yùn)動(dòng)仿真 594.5.1 仿真一般步驟 .594.5.2 機(jī)構(gòu)運(yùn)動(dòng)分析的任務(wù)和方法 .604.5.3 運(yùn)動(dòng)的生成 .614.5.4 運(yùn)動(dòng)分析 .61總 結(jié) .63參考文獻(xiàn) .64致 謝 656
