NGW 行星減速器的設(shè)計(jì) 摘 要 本文完成了對(duì)一級(jí)行星齒輪減速器的結(jié)構(gòu)設(shè)計(jì)。該減速器具有較小的傳動(dòng)比，而且，它具有結(jié)構(gòu)緊湊、傳動(dòng)效率高、外廓尺寸小和重量輕、承載能力大、運(yùn)動(dòng)平穩(wěn)、抗沖擊和震動(dòng)的能力較強(qiáng)、噪聲低的特點(diǎn)，適用于化工、輕工業(yè)以及機(jī)器人等領(lǐng)域。 首先簡(jiǎn)要介紹了課題的背景以及齒輪減速器的研究現(xiàn)狀和發(fā)展趨勢(shì)，然后比較了各種傳動(dòng)結(jié)構(gòu)，從而確定了傳動(dòng)的基本類型。其中該減速器的設(shè)計(jì)與其他減速器的結(jié)構(gòu)設(shè)計(jì)相比有三大特點(diǎn)：其一，為了使三個(gè)行星輪的載荷均勻分配，采用了齒式浮動(dòng)機(jī)構(gòu)，即太陽(yáng)輪與高速軸通過(guò)齒式聯(lián)軸器將二者連接在一起，從而實(shí)現(xiàn)了太陽(yáng)輪的浮動(dòng)；其二，該減速器的箱體采用的是法蘭式箱體，上下箱體分別鑄造而成；其三，內(nèi)齒圈與箱體采用分離式，通過(guò)螺栓和圓錐銷將其與上下箱體固定在一起。 關(guān)鍵 詞： 行星齒輪，傳動(dòng)機(jī)構(gòu)，結(jié)構(gòu)設(shè)計(jì)，校核計(jì)算 . . The design of NGW plaary gear reducer ABSTRACT This pleted a singlestage plaary gear reducer design. The gear has a smaller transmission ratio, and it has a pact, high transmission efficiency, outline, small size and light weight, carrying capacity, smooth motion, shock and vibration resistant and low noise characteristics, Used in chemical, light industry and robotics fields. The function of the development of modern mechanical transmission has a more important significance. First paper introduces the background and the subject of gear reducer situation and development trend, and then pared various transmission structures, which determine the basic type of transmission. Thesis is the main part of the main ponents of drive mechanism including the sun wheel, pla gear, ring gear and pla carrier in the design calculation, given by the input power, gear ratio, input speed and the condition factor to determine the approximate structure after the gear reducer And to carry out the design and calculation of the overall structure and main ponents of the strength check calculation. One of the other gear reducer design and pared the structural design of the three major characteristics: First, the three plaary gear to make the load evenly, using a geartype floating body, the sun gear and highspeed shaft through the gear together Coupling the two together to achieve a floating sun gear。 Third, the ring gear and Box with separate, through bolts and tapered pins will be fixed together with the upper and lower box. Finally, a summary of the entire design process is basically plete the overall design of the reducer.
