行星減速機(jī)主要結(jié)構(gòu)特點(diǎn)簡介？行星減速機(jī)不同心斷軸解決方法有哪些？
主要結(jié)構(gòu)及特點(diǎn)
行星減速機(jī)主要傳動結(jié)構(gòu)為：行星輪，太陽輪，外齒圈.行星減速機(jī)因為結(jié)構(gòu)原因，單級減速最小為3，最大一般不超過10，常見減速比為：3.4.5.6.8.10，減速機(jī)級數(shù)一般不超過3，但有部分大減速比定制減速機(jī)有4級減速.
相對其他減速機(jī),行星減速機(jī)具有高剛性，高精度（單級可做到1分以內(nèi)），高傳動效率（單級在97%-98%），高的扭矩/體積比，終身免維護(hù)等特點(diǎn).
因為這些特點(diǎn)，行星減速機(jī)多數(shù)是安裝在步進(jìn)電機(jī)和伺服電機(jī)上，用來降低轉(zhuǎn)速，提升扭矩，匹配慣量.
減速機(jī)額定輸入轉(zhuǎn)速最高可達(dá)到18000rpm（與減速機(jī)本身大小有關(guān)，減速機(jī)越大，額定輸入轉(zhuǎn)速越小）以上，工業(yè)級行星減速機(jī)輸出扭矩一般不超過2000Nm，特制超大扭矩行星減速機(jī)可做到10000Nm以上.工作溫度一般在-25℃到100℃左右，通過改變潤滑脂可改變其工作溫度.

重要優(yōu)勢
行星減速器內(nèi)部齒輪采用20CrMnTi滲碳淬火和磨齒具有體積小、重量輕，承載能力高，使用壽命長、運(yùn)轉(zhuǎn)平穩(wěn)，噪聲低、輸出扭矩大，速比大、效率高、性能安全的特點(diǎn)。兼具功率分流、多齒嚙合獨(dú)用的特性。是一種具有廣泛通用性的新型減速機(jī)。最大輸入功率可達(dá)104kW。適用于起重運(yùn)輸、工程機(jī)械、冶金、礦山、石油化工、建筑機(jī)械、輕工紡織、醫(yī)療器械、儀器儀表、汽車、船舶、兵器和航空航天等工業(yè)部門行星系列新品種WGN定軸傳動減速器、WN子母齒輪傳動減速器、彈性均載少齒差減速器。

行星減速機(jī)不同心斷軸解決方法
當(dāng)驅(qū)動電機(jī)和減速機(jī)間裝配同心度保證得較好時，驅(qū)動電機(jī)輸出軸所承受的僅僅是轉(zhuǎn)動力（扭矩），運(yùn)轉(zhuǎn)時也會很平順，沒有脈動感。而在不同心時，驅(qū)動電機(jī)輸出軸還要承受來自于減速機(jī)輸入端的徑向力（彎矩）。
這個徑向力的作用將會使驅(qū)動電機(jī)輸出軸被迫彎曲，而且彎曲的方向會隨著輸出軸轉(zhuǎn)動不斷變化。如果同心度的誤差較大時，該徑向力使電機(jī)輸出軸局部溫度升高，其金屬結(jié)構(gòu)不斷被破壞，最終將導(dǎo)致驅(qū)動電機(jī)輸出軸因局部疲勞而折斷。兩者同心度的誤差越大時，驅(qū)動電機(jī)輸出軸折斷的時間越短。
在驅(qū)動電機(jī)輸出軸折斷的同時，減速機(jī)輸入端同樣也會承受來自于驅(qū)動電機(jī)輸出軸方面的徑向力，如果這個徑向力超出減速機(jī)輸入端所能承受的最大徑向負(fù)荷的話，其結(jié)果也將導(dǎo)致減速機(jī)輸入端產(chǎn)生變形甚至斷裂或輸入端支撐軸承損壞。
因此，在裝配時保證同心度至關(guān)重要！從裝配工藝上分析，如果驅(qū)動電機(jī)軸和減速機(jī)輸入端同心，那么驅(qū)動電機(jī)軸面和減速機(jī)輸入端孔面間就會很吻合，它們的接觸面緊緊相貼，沒有徑向力和變形空間。而裝配時如果不同心，那么接觸面之間就會不吻合或有間隙，就有徑向力并給變形提供了空間。
同樣，減速機(jī)的輸出軸也有折斷或彎曲現(xiàn)象發(fā)生，其原因與驅(qū)動電機(jī)的斷軸原因相同。但減速機(jī)的出力是驅(qū)動電機(jī)出力和減速比之積，相對于電機(jī)來講出力更大，故減速機(jī)輸出軸更易被折斷。因此，用戶在使用減速機(jī)時，對其輸出端裝配時同心度的保證更應(yīng)十分注意！
