7500t/h装船机总体设计及回转机构设计(含CAD零件图装配图)(任务书,开题报告,外文翻译,论文说明书13000字,CAD图4张)
摘要
本次毕业设计根据港口机械的相关知识,对7500t/h装船机进行了总体设计和回转机构的设计。在总体设计中,首先完成了各类载荷的计算并进行了载荷组合,其次完成了对装船机轮压的计算及校核,最后,根据计算的载荷来检查抗倾覆性和抗风防滑稳定性。
回转机构的设计分为两部分,一是回转支承装置的设计计算,二是回转驱动装置的设计计算。根据计算所得载荷及力矩选取了回转支承装置和液压马达,再根据实际工况设计液压传动回路,选取液压泵等相关液压元件,确定传动比选择减速箱,最后根据实际尺寸完成回转机构的整体布置。
本文的特色是利用液压传动的方式来驱动回转机构的运行。所设计的液压回路同样也适用于其他大型机械的回转机构,具有一般普遍性。

Abstract
This graduation project designed the 7500t/h ship loading machine based on the relevant knowledge of port machinery. In the overall design, the calculation of all kinds of loads was first completed and the load combination was completed. Then, the calculation and verification of the wheel pressure of the ship loader was completed. Finally, the stability against load and non-slip stability were checked. [版权所有:http://DOC163.com]
The design of the slewing mechanism is divided into two parts. One is the design calculation of the slewing bearing device, and the other is the design calculation of the slewing drive device. The slewing bearing device and hydraulic motor are selected according to the calculated load and torque, and the hydraulic transmission circuit is designed according to the actual working conditions. Hydraulic components such as hydraulic pump are selected .Then to determine the gear ratio and the gearbox is selected. Finally, the overall layout of the slewing mechanism is completed according to the actual size.
The feature of this article is to use hydraulic transmission to drive the rotation mechanism. The designed hydraulic circuit is also applicable to the slewing mechanism of other large-scale machinery, and it has general universality.
Key Words: ship loader;load calculation;slewing mechanism;hydraulic transmission
