1 摘要本次毕业设计的题目是履带式液压挖掘机功挖掘机。和其他类型的比较,类似于这种类型的挖掘机性能良好并且应用广泛,软土地表面或沼泽地面也可以行使使用,并且可以减少对地面的压力。液压挖掘机的主要特点是:可无级调速,调速范围大,能得到较低的稳定转速, 动作快,液压元件的运动的运动惯性,加速性能好,并能高速反转,传输是非常顺利,非常简单的结构,可吸收的影响和振动,操作省力,易实现自动控制,易于实现标准化,系列化,泛化。本设计斗容量是 Q= 3,它属于小型液压挖掘机,工作装置的传动原理,液压挖掘机,主要设计。本次毕业设计,选择为履带式的液压挖掘机,为了满足要求。在转盘上表面是整个旋转,因此它可以在更大的范围内工作。由于采用液压传动与控制可以提高整体性能。随着现代挖掘机相比,开采量增加到 2~3倍,质量大约是 6吨,挖掘力约为 30kN ,排放的最大高度约为 ,最大挖掘深度 ,最大挖掘半径大约是 ,可从机器的操作能力有了很大的提高,不仅挖掘能力大,和机器的重量,传动平稳,工作效率很高,结构紧凑 2 ABSTRACT The topic of this graduation design is mining mechanism of Hydraulic Excavator Power crawler. The hydraulic excavators and other types 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, 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, labor-saving 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 ina greater scope. Because of the use of hydraulic transmission and control the overall performance can be improved. Compared with modern excavator, the mining capacity increased to2~3 times, the quality is about 6 tons, digging force is about 30kN, the maximum discharge height is about , the m
