4、獨立的閉式傳動裝置，用來降低轉速和增大轉矩，以滿足工作需要，在某些場合也用來增速，稱為增速器?！　∵x用減速器時應根據(jù)工作機的選用條件，技術參數(shù)，動力機的性能，經(jīng)濟性等因素，比較不同類型、品種減速器的外廓尺寸，傳動效率，承載能力，質(zhì)量，價格等，選擇最適合的減速器。 </p><p>　　減速器的類別、品種、型式很多，目前已制定為行（國）標的減速器有40余種。減速器的類別是根據(jù)所采用的齒輪齒形、齒廓曲線劃分；減速器

5、的品種是根據(jù)使用的需要而設計的不同結構的減速器；減速器的型式是在基本結構的基礎上根據(jù)齒面硬度、傳動級數(shù)、出軸型式、裝配型式、安裝型式、聯(lián)接型式等因素而設計的不同特性的減速器。 </p><p>　　與減速器聯(lián)接的工作機載荷狀態(tài)比較復雜，對減速器的影響很大，是減速器選用及計算的重要因素，減速器的載荷狀態(tài)即工作機（從動機）的載荷狀態(tài)，通常分為三類：　?、佟鶆蜉d荷;　?、凇械葲_擊載荷;　?、邸獜姏_擊載荷。&l

6、t;/p><p>　　由于編者水平有限，設計中有錯誤與不當之處在所難免，希望大家批評指正。</p><p>　　關鍵字：減速器、齒輪、軸承、聯(lián)接</p><p>　　目 錄</p><p>　　摘要···········
