45T旋挖钻机变幅机构液压缸设计
内容摘要:
本文主要介绍了旋挖钻机变幅机构液压缸的设计。液压缸的设计包括了系统工作压力的确定、液压缸活塞直径的确定和活塞杆直径的确定、液压缸壁厚和外径的计算、缸盖厚度的确定、缸体长度的确定以及活塞杆稳定性的验算。本文结合传统设计和计算机辅助工程技术，先依据经验公式计算，确定了液压缸安装方案，设计了液压缸活塞及活塞杆尺寸参数，校核了匹配的连接螺栓，销轴等；完成了变幅及变角度液压缸的设计计算。然后利用AutoCAD，Pro/Engineer辅助设计平台，完成了液压缸所有零件的二维及三维建模。通过分析的数据校核了先前的设计，同时为进一步优化设计和系列化设计提供了依据。

45T spiral drill luffing mechanism design of hydraulic cylinder
Content abstract:
This design is mainly introduced the rotating drill luffing mechanism design of hydraulic cylinder. The design of hydraulic cylinder including ensure pressure system of the hydraulic cylinder piston, piston rod diameter and the diameter and wall thickness and diameter of hydraulic cylinder cylinder, the thickness of the calculation of the length, and the cylinder piston rod stability of calculation. In this thesis, by the use of traditional design and computer-aided engineering（CAE）, firstly based on experience of the formula calculation to determined the installation scheme of the hydraulic cylinder, design size parameters of hydraulic cylinder piston and piston, Check the matching of connecting bolts, pin shaft, etc.;complete the design and calculation of the range and angle of hydraulic cylinder. Then by the use of AutoCAD,Pro / MECHANICA platform, Complete all parts of the hydraulic cylinder 2d and 3d modeling.The analysis data verificated the previous design, at the same time ,applied references for further Optimal Design and Series Design.
