減速器主要由傳動零件(齒輪或蝸桿)、軸、軸承、箱體及其附件所組成。其基本結(jié)構(gòu)有三大部分：
1、齒輪、軸及軸承組合
小齒輪與軸制成一體，稱齒輪軸，這種結(jié)構(gòu)用于齒輪直徑與軸的直徑相關(guān)不大的情況下，如果軸的直徑為d，齒輪齒根圓的直徑為df，則當(dāng)df-d≤6～7mn時，應(yīng)采用這種結(jié)構(gòu)。而當(dāng)df-d>6～7mn時，采用齒輪與軸分開為兩個零件的結(jié)構(gòu)，如低速軸與大齒輪。此時齒輪與軸的周向固定平鍵聯(lián)接，軸上零件利用軸肩、軸套和軸承蓋作軸向固定。兩軸均采用了深溝球軸承。這種組合，用于承受徑向載荷和不大的軸向載荷的情況。當(dāng)軸向載荷較大時，應(yīng)采用角接觸球軸承、圓錐滾子軸承或深溝球軸承與推力軸承的組合結(jié)構(gòu)。軸承是利用齒輪旋轉(zhuǎn)時濺起的稀油，進行潤滑。箱座中油池的潤滑油，被旋轉(zhuǎn)的齒輪濺起飛濺到箱蓋的內(nèi)壁上，沿內(nèi)壁流到分箱面坡口后，通過導(dǎo)油槽流入軸承。當(dāng)浸油齒輪圓周速度υ≤2m/s時，應(yīng)采用潤滑脂潤滑軸承，為避免可能濺起的稀油沖掉潤滑脂，可采用擋油環(huán)將其分開。為防止?jié)櫥土魇Ш屯饨缁覊m進入箱內(nèi)，在軸承端蓋和外伸軸之間裝有密封元件。

PCVD法沉積溫度低，膜基結(jié)合力及工藝繞鍍性均較PVD法有較大改進，但與擴散法相比，膜基結(jié)合力仍有較大差距，此外由于PCVD法仍為等離子體成膜，雖然繞鍍性較PVD法有所改善，但無法消除。由擴散法金屬碳化物覆層技術(shù)形成的金屬碳化物覆層，與基體形成冶金結(jié)合，具有PVPCVD無法比擬的膜基結(jié)合力，因此該技術(shù)真正能夠發(fā)揮超硬膜層的性能優(yōu)勢，此外，該技術(shù)不存在繞鍍性問題，后續(xù)基體硬化處理方便，并可多次重復(fù)處理，使該技術(shù)的適用性更為廣泛。

　　不同勵磁方式的直流電機有著不同的特性。一般情況直流電動機的主要勵磁方式是并勵式、串勵式和復(fù)勵式，直流發(fā)電機的主要勵磁方式是他勵式、并勵式和和復(fù)勵式。
直流電動機的特點
　　(一)調(diào)速性能好。所謂“調(diào)速性能”，是指電動機在一定負載的條件下，根據(jù)需要，人為地改變電動機的轉(zhuǎn)速。直流電動機可以在重負載條件下，實現(xiàn)均勻、平滑的無級調(diào)速，而且調(diào)速范圍較寬。
　　(二)起動力矩大�？梢跃鶆蚨�(jīng)濟地實現(xiàn)轉(zhuǎn)速調(diào)節(jié)。因此，凡是在重負載下起動或要求均勻調(diào)節(jié)轉(zhuǎn)速的機械，例如大型可逆軋鋼機、卷揚機、電力機車、電車等，都用直流電動機拖動。
大致應(yīng)用了“通電導(dǎo)體在磁場中受力的作用”的原理，勵磁線圈兩個端線同有相反方向的電流，使整個線圈產(chǎn)生繞軸的扭力，使線圈轉(zhuǎn)動。
　　要使電樞受到一個方向不變的電磁轉(zhuǎn)矩，關(guān)鍵在于：當(dāng)線圈邊在不同極性的磁極下，如何將流過線圈中的電流方向及時地加以變換， 即進行所謂“換向”。 為此必須增添一個叫做換向器的裝置，換向器配合電刷可保證每個極下線圈邊中電流始終是一個方向，就可以使電動機能連續(xù)的旋轉(zhuǎn),這就是直流電動機的工作原理
