7、、機(jī)械效率高等優(yōu)點(diǎn) ?。但受其傳動(dòng)的理論的限制，不能傳遞過大的功率，功率一般都要小于 40kw。由于在傳動(dòng)的理論上、工藝水平和材料品質(zhì)方面沒有突破，因此，沒能從根本上解決傳遞功率大、傳動(dòng)比大、體積小、重量輕、機(jī)械效率高等這些基本要求。 90 年代初期，國內(nèi)出現(xiàn)的三環(huán)（齒輪）減速器，是一種外平動(dòng)齒輪傳動(dòng)的減速器， 它可實(shí)現(xiàn)較大的傳動(dòng)比， 傳遞載荷的能力也大。 它的體積和重量都比定軸齒輪減速器輕，結(jié)構(gòu)簡單，效率亦高。由于該減速器的三軸平行結(jié)構(gòu)，。2。故使功率 / 體積（或重量）比值仍小。且其輸入軸與輸出軸不在同一軸線上，這在使用上有許多不便。 北京理工大學(xué)研制成功的 內(nèi)平動(dòng)齒輪減速器 不僅具有三環(huán)

8、減速器的優(yōu)點(diǎn)外，還有著大的功率 / 重量（或體積）比值，以及輸入軸和輸出軸在同一軸線上的優(yōu)點(diǎn)， 處于國內(nèi)領(lǐng)先地位。 國內(nèi)有少數(shù)高等學(xué)校和廠礦企業(yè)對(duì)平動(dòng)齒輪傳動(dòng)中的某些原理做些研究工作， 發(fā)表過一些研究論文， 在利用擺線齒輪作平動(dòng)減速器開展了一些工作。（二）、平動(dòng)齒輪減速器工作原理簡介 , 平動(dòng)齒輪減速器是指一對(duì)齒輪傳動(dòng)中，一個(gè)齒輪在平動(dòng)發(fā)生器的驅(qū)動(dòng)下作平面平行運(yùn)動(dòng)， 通過齒廓間的嚙合， 驅(qū)動(dòng)另一個(gè)齒輪作定軸減速轉(zhuǎn)動(dòng)， 實(shí)現(xiàn)減速傳動(dòng)的作用。 平動(dòng)發(fā)生器可采用平行四邊形機(jī)構(gòu)，或正弦機(jī)構(gòu)或十字滑塊機(jī)構(gòu)。 本成果采用平行四邊形機(jī)構(gòu)作為平動(dòng)發(fā)生器。平動(dòng)發(fā)生器可以是虛擬的采用平行四邊形機(jī)構(gòu)， 也可以是實(shí)體

9、的采用平行四邊形機(jī)構(gòu)。有實(shí)用價(jià)值的平動(dòng)齒輪機(jī)構(gòu)為內(nèi)嚙合齒輪機(jī)構(gòu)， 因此又可以分為內(nèi)齒輪作平動(dòng)運(yùn)動(dòng)和外齒輪作平動(dòng)運(yùn)動(dòng)兩種情況。 外平動(dòng)齒輪減速器構(gòu)， 其內(nèi)齒輪作平動(dòng)運(yùn)動(dòng)，驅(qū)動(dòng)外齒輪并作減速轉(zhuǎn)動(dòng)輸出。該機(jī)構(gòu)亦稱三環(huán)（齒輪）減速器。由于內(nèi)齒輪作平動(dòng)， 兩曲柄中心設(shè)置在內(nèi)齒輪的齒圈外部， 故其尺寸不緊湊， 不能解決體積較大的問題。 內(nèi)平動(dòng)齒輪減速， 其外齒輪作平動(dòng)運(yùn)動(dòng)， 驅(qū)動(dòng)內(nèi)齒輪作減速轉(zhuǎn)動(dòng)輸出。 由于外齒輪作平動(dòng)， 兩曲柄中心能設(shè)置在外齒輪的齒圈內(nèi)部， 大大減少了機(jī)構(gòu)整體尺寸。 由于內(nèi)平動(dòng)齒輪機(jī)構(gòu)傳動(dòng)效率高、 體積小、輸入輸出同軸線，故由廣泛的應(yīng)用前景。（三）、本項(xiàng)目的技術(shù)特點(diǎn)與關(guān)鍵技術(shù)本項(xiàng)目的技術(shù)

10、特點(diǎn) , 本新型的 內(nèi)平動(dòng)齒輪減速器 與國內(nèi)外已有的齒輪減速器相比較，有如下特點(diǎn)：（1）傳動(dòng)比范圍大，自 I=10 起，最大可達(dá)幾千。若制作成大傳動(dòng)比的減速器，則更顯示出本減速器的優(yōu)點(diǎn)。（2）傳遞功率范圍大：并可與電動(dòng)機(jī)聯(lián)成一體制造。（3）結(jié)構(gòu)簡單、體積小、重量輕。比現(xiàn)有的齒輪減速器減少 1/3 左右。（4）機(jī)械效率高。嚙合效率大于 95%，整機(jī)效率在 85%以上，且減速器的效率將不隨傳動(dòng)比的增大而降低，這是別的許多減速器所不及的。（5）本減速器的輸入軸和輸出軸是在同一軸線上。本減速器與其它減速器的性能比較見表 1。因缺少數(shù)據(jù)，表中所列的各減速器的功率 / 重量比是最優(yōu)越的。各類減速器比較型號(hào)

12、的平行移動(dòng)需要有輔助機(jī)構(gòu)幫助實(shí)現(xiàn)的，可采用（ 612 副）銷軸、滾子作為虛擬輔助平動(dòng)機(jī)構(gòu)， 也可以采用偏心軸作為實(shí)體輔助平動(dòng)機(jī)構(gòu)。 內(nèi)平動(dòng)齒輪減速器的關(guān)鍵技術(shù)和關(guān)鍵工藝是組成平行四邊形構(gòu)件的尺寸計(jì)算及其要求的加工精度、 輪齒主要參數(shù)的選擇。 這些因數(shù)都將影響傳動(dòng)的能力和傳動(dòng)的質(zhì)量。 總的說，組成本減速器的各零部件都要求有較高的精度，它們將決定著減速器的整體傳動(dòng)質(zhì)量。 3. 本項(xiàng)目的概況本項(xiàng)目已獲得中國實(shí)用新型專利，專利號(hào)： ZL95227767.0。本項(xiàng)目自 1995 年試制出第一臺(tái)樣機(jī)（功率 2.5kW，傳動(dòng)比 I=32 ）后，陸續(xù)與一。3。些廠礦合作，設(shè)計(jì)了下面幾種不同功率、不同傳動(dòng)比的減
