減速器英文翻譯

1、、什么是減速器 減速器是一種動(dòng)力傳達(dá)機(jī)構(gòu)，利用齒輪的速度轉(zhuǎn)換器，將馬達(dá)的回轉(zhuǎn)數(shù)減 速到所要的回轉(zhuǎn)數(shù)，并得到較大轉(zhuǎn)矩的機(jī)構(gòu)。 1減速器的作用 1 ）降速同時(shí)提高輸出扭矩，扭矩輸出比例按電機(jī)輸出乘減速比，但要注意 不能超出減速器額定扭矩。 2 ）減速同時(shí)降低了負(fù)載的慣量，慣量的減少為減速比的平方。大家可以 看一下一般電機(jī)都有一個(gè)慣量數(shù)值。 2、減速器的種類 一般的減速器有斜齒輪減速器（包括平行軸斜齒輪減速器、蝸輪減速器、錐 齒輪減速器等等）、行星齒輪減速器、擺線針輪減速器、蝸輪蝸桿減速器、行星 摩擦式機(jī)械無級變速機(jī)等等。 3、常見減速器 1 ）蝸輪蝸桿減速器的主要特點(diǎn)是具有反向自鎖功能，可以有較大

2、的減速 比，輸入軸和輸出軸不在同一軸線上，也不在同一平面上。但是一般體積較大， 傳動(dòng)效率不咼，精度不咼。 2 ）諧波減速器的諧波傳動(dòng)是利用柔性元件可控的彈性變形來傳遞運(yùn)動(dòng)和 動(dòng)力的，體積不大、精度很高，但缺點(diǎn)是柔輪壽命有限、不耐沖擊，剛性與金 屬件相比較差。輸入轉(zhuǎn)速不能太高。 3 ）行星減速器其優(yōu)點(diǎn)是結(jié)構(gòu)比較緊湊，回程間隙小、精度較高，使用壽 命很長，額定輸出扭矩可以做的很大。但價(jià)格略貴一、對裝配前零件的要求 1. 滾動(dòng)軸承用汽油清洗，其他零件用煤油清洗。所有零件和箱體內(nèi)不許有任何 雜質(zhì)存在 。箱體內(nèi)壁和齒輪（蝸輪）等未加工表面先后涂兩次不被機(jī)油侵蝕 的耐油漆，箱體外表 面先后涂底漆和顏色油漆

7、更突出， 使用壽命不長。國內(nèi)使用的大 型減速器（500kw以上），多從國外（如丹麥、德國等）進(jìn)口。 60年代開始生產(chǎn) 的少齒差傳動(dòng)、擺線針輪傳動(dòng)、諧波傳動(dòng)等減速器具有傳動(dòng)比大，體積小、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

8、該減速器的三軸平行結(jié)構(gòu)， 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)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 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

9、。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，

10、 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) 1. 本項(xiàng)目的技術(shù)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1=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）

11、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 功率（kw）減速比 質(zhì)量 （kg） QI-450 93 31.5 1820 ZSY-250 95 31.5 540 NGW-938.1 31.5 577 SEW德 國）90 28.61 1300 NP-100? 100 30 400 注：NP-100 為內(nèi)平動(dòng)齒輪減速器，SEW 減速器的質(zhì)量含電機(jī)。2.本項(xiàng)目的關(guān)鍵技術(shù)。由圖2可知，內(nèi)平動(dòng)齒輪減速器 是由內(nèi)齒輪Z2、外齒輪Z1和平行四邊形機(jī)構(gòu)組合而成的。它的傳動(dòng)原理是：電 機(jī)輸入旋轉(zhuǎn)運(yùn)

Because in the tran smissi on theoretically, the tech no logical level and the material quality aspect has not broke n through, therefore, has not bee n able fun dame ntallyto solve the transmission power in a big way, the velocity ratio big, the volume small, the weight light,

37、mecha ni calefficie ncyhigher these requests basically.The 90s in itial period, the home appears three links (gear) the reducti on gear, is one kind of outside stable moti on gear drive reduction gear, it mayrealize the great velocity ratio, transmission load ability is also big. Its volume and the

38、weight are all lighter tha n the dead axle speed reducer gear, the structure is simple, the efficiency is also high.Because this reducti on gear three axle parallel structure, therefore caused the power/volume (or weight) the ratio is still small.Also its in put axis and the output shaft on the ide

Because exter nal tooth crop rotation parallelmigration,therefore namestable

54、 motion gear mecha ni sm.The gear parallel migrati on n eeds to have the auxiliary body help realizati on, may use (612) to sell the axis, the roller takes the hypothesized auxiliary stable motion organization,also may use the ecce ntric shaft to take theen tityauxiliary stablemoti on orga ni zati o

55、nnthe stable moti on speed reducer gear key tech no logies and the esse ntial craft are the compositi on parallelogram comp onent size computati on and the request process ing precisi on, the gear teeth main parameter choice. These factors will all affect the transmissionability and the tran smissi

56、on quality.Overall speak ing, the group cost reduct ion gear various spare parts all request to have the high precision, they will be decid ing the reduct ion gear overall tran smis3. this project survey this project has obta ined the Chin ese practical new pate nt, the pate nt nu mber: ZL95227767.0

57、? .? This project trial produced the first prototype from 1995 (power 2.5kW, after velocity ratio 1=32), with some factory and mine cooperati on, has one after ano ther desig ned follow ing several kind of differe nt powers, the differe nt velocity ratio reduct ion gear. (1) electrically operated on

58、 rollers gate uses the reduction gear, power 550W, velocity ratio I=26, is un ited as one body with the electrical mach in ery.si on quality. (2) mixer uses the reducti on gear, power 370W, velocity ratio 1=17. (3) some military goods use two kind of reduct ion gears, one kind of power 370W, velocity ratio 1=23.5; Ano ther kind of power 370W, velocity ratio I=103 two level of tran smissi on reducti on gear. (4) steel mill large package rotary abutment reduction gear, power 7.5kw, velocity ratio 1=64. (5) steel m
