漸開線少齒差行星齒輪減速器設(shè)計(jì)（零齒差輸出機(jī)構(gòu)）

1、漸開線少齒差行星齒輪減速器的設(shè)計(jì)（零齒差輸出機(jī)構(gòu)）摘要在條件為輸入轉(zhuǎn)速為1450轉(zhuǎn)分鐘、輸入功率為5KW、傳動(dòng)比為25等這些技術(shù)參數(shù)的基礎(chǔ)上設(shè)計(jì)一漸開線少齒差行星齒輪減速器。漸開線行星齒輪減速器傳動(dòng)與普通定軸減速器傳動(dòng)相比具有承載能力大、體積小、效率高、重量輕、傳動(dòng)比大、噪聲小、可靠性高、壽命長(zhǎng)、便于維修等優(yōu)點(diǎn)，同時(shí)還可以提高其承載能力。本設(shè)計(jì)最主要的過程就是少齒差和零齒差設(shè)計(jì)參數(shù)的選取與計(jì)算，特別是變位系數(shù)的選取，需通過Matlab軟

2、件編程計(jì)算，這樣很大程度上節(jié)省了因選取的變位系數(shù)不當(dāng)而需重新計(jì)算所需要的時(shí)間。還可以多次給定初值選取最佳的變位系數(shù)，從而有利于少齒差和零齒差的結(jié)構(gòu)設(shè)計(jì)。同時(shí)還需對(duì)軸類零件、端蓋、箱體的結(jié)構(gòu)設(shè)計(jì)，裝配時(shí)，需要對(duì)軸承、密封圈、擋圈、鍵進(jìn)行選用。關(guān)鍵詞：關(guān)鍵詞：減速器行星齒輪優(yōu)化設(shè)計(jì)Keywd:Thereductiongearplagearoptimizesthedesign目錄目錄第一章概述.........................
