毕业设计（论文） 题 目： 液压挖掘机反铲工作装置设计 学 院： 航空制造工程学院 专业名称： 机械设计制造及其自动化 班级学号： 学生姓名： 指导教师： 二O 年 月 The Design for Backhoe Equipment of the Hydraulic Excavator Student name : Dong Chen xi Class: 080317 Supervisor: Xing Pu Abstract: Hydraulic excavator is an important engineering machinery. Its wide application played a tremendous role to reducing the volume of labor and to ensuring project quality and to accelerating progress and to increasing productivity. Backhoe working devices is made up of a moving arm and a fighting pole and shovel and a hydraulic tank of moving arm and a hydraulic tank of fighting pole and a hydraulic tank of shovel. Based on the hydraulic excavator backhoe device characteristics and the structure of principle , to all the major institutions of the kinematic analysis . On this basis , in accordance with the design specification design requirements , with the bodies of the characteristics and design requirements , in terms of the various agencies at the same time , combining elements of known size parameters , calculated in the component agencies of other parameters , for various components , The shape of design data support. Mining is a measure of the ability of excavators digging the important parameters. Mining is done by the hydraulic cylinder of the pressure on the oil , is initiative , the largest excavation of the realization by many factors , it is also working device to hinge point Analysis of the foundation . Mining resistance not only reflect the size of bucket shape , but also with the excavation of the object , is a comprehensive reflection of the two.
