悬臂纵轴式掘进机的总体设计(中文4600字,英文3100字)
总体设计是机械产品设计过程中的重要内容和主要环节，它是在方案设计之后紧接着进行的设计工作。悬臂纵轴式掘进机(以下简称掘进机)的总体设计对整机性能的优劣起着决定性的作用，并决定了各总成、系统、各部件之间的协调性，统一性和匹配关系，从而获得总体的高端 性能和较好的技术经济效益。
掘进机的总体设计，主要包括以下内容：
1）据设计任务书选择机型及各部件结构型式
2）定整机的主要技术性能参数，包括尺寸参数、重量参数、运动参数和技术经济指标
3）按照总体设计的性能要求，确定整机系统的组成 及它们之间的匹配性以及各个部件的主要技术参数
4）进行必要的总体计算，并绘制传动、液压、电控系统图等。
1．选定该机型和各个部件及其结构型式、驱动方式、并进行总体的合理布置
The vertical Boom-type Roadheader design
Mechanical design is in the process of product design and an important part of the main links, it is followed in programme design after the design work. The vertical Boom-type roadheader (the roadheader) to the overall design of the merits of complete machine play a decisive role, and the decision of the assembly, the system, coordination between the various components of the unity and match, to obtain the high-end performance and overall better economic efficiency technology.
Roadheader design, including the following:
1) According to design project description choice type and various cellular construction pattern
2) Decides the complete machine the main technical performance parameter, Including size parameter, heavy parameter, the parameter of movement and the technical economy refer parameter,
3) According to system design performance requirement, definite complete machine system composition and between them match as well as each part main technical senate parameter,
4) The necessary whole, and the mapping of transmission, hydraulic, electronic control systems, and other plans.
1 the selected models and various components and structural type, drive, and the overall layout of the reasonable
In determining the content, first task should be designed to meet the contents, especially the users of the main demands of the investigation, the two sides exchanged views repeatedly, to satisfy both users (or superior) conditions, can better meet the product development of the overall plan.
1) the selected models |
