1 JIANGXI AGRICULTURAL UNIVERSITY 本 科 畢 業(yè) 論 文(設 計) 題目 : 液壓挖掘機 學 院: 工學院 姓 名: 學 號: 20xx1172 專 業(yè): 機械制造及其自動化 年 級: 機制 1004 指導教師: 職 稱: 導師 1 摘 要 全套圖紙,加 153893706 本次畢業(yè)設計的題目是履帶式液壓挖掘機功挖掘機。和其他類型的比較,類似于這種類型的挖掘機性能良好并且應用廣泛,軟土地表面或沼澤地面也可以行使使用,并且可以減少對地面的壓力。 液壓挖掘機的主要特點是:可無級調速,調速范圍大,能得到較低的穩(wěn)定轉速,動作快,液壓元件的運動的運動慣性,加速性能好,并能高速反轉,傳輸是非常順利,非常簡單的結構,可吸收的影響和振動,操作省力,易實現自動控制,易于實現標準化,系列化,泛化。 本設計斗容量是 Q=179。,它屬于小型液壓挖掘機,工作裝置的傳動 原理,液壓挖掘機,主要設計。 本次畢業(yè)設計,選擇為履帶式的液壓挖掘機,為了滿足要求。在轉盤上表面是整個旋轉,因此它可以在更大的范圍內工作。由于采用液壓傳動與控制可以提高整體性能。隨著現代挖掘機相比,開采量增加到 2 ~ 3 倍,質量大約是 6 噸,挖掘 2 力約為 30kN,排放的最大高度約為 ,最大挖掘深度 ,最大挖掘半徑大約是 ,可從機器的操作能力有了很大的提高,不僅挖掘能力大,和機器的重量,傳動平穩(wěn),工作效率很高,結構緊湊 ABSTRACT The topic of this graduation design is mining mechanism of Hydraulic Excavator Power crawler. The hydraulic excavators and other types of parison, similar to this type of excavator with good performance and the application is wide, the soft land surface or marshy ground area can also use widening, lengthening and floating track to reduce the earth pressure of the. The main characteristics of hydraulic excavator is: can the stepless speed regulation and speed range is very large, can obtain a lower stable rotational speed, fast action, hydraulic ponent motion motion inertia, acceleration performance is very good, and can operate high speed reversal, the transmission is very smooth, very simple structure, can absorb the impact and vibration, laborsaving operation, easy to realize automatic control, easy to realize the standardization, seriation, generalization. This design is the main parameters of bucket capacity of , it belongs to the small hydraulic excavator working device, hydraulic excavator, the main design of transmission principle. In the graduation design, the crawler walking device, in order to meet the requirements of. Upper surface of the turnplate is the entire rotation, therefore it may work in a greater scope. Because of the use of hydraulic tra
