带式运输机的传动装置——二级圆柱齿轮减速器的设计过程 毕业设计论文.docVIP

摘 要 齿轮传动是现代机械中应用最广的一种传动形式。它由齿轮、轴、轴承及箱体组成的齿轮减速器，用于原动机和工作机或执行机构之间，其匹配转速和传递转矩的作用。齿轮减速器的特点是效率高、寿命长、维护简便，因而应用极为广泛。 本设计讲述了带式运输机的传动装置——二级圆柱齿轮减速器的设计过程。首先进行了传动方案的评述，选择齿轮减速器作为传动装置，然后进行减速器的设计计算（包括选择电动机、设计齿轮传动、轴的结构设计、选择并验算滚动轴承、选择并验算联轴器、校核平键连接、选择齿轮传动和轴承的润滑方式九部分内容）。运用AutoCAD软件进行齿轮减速器的二维平面设计，完成齿轮减速器的二维平面零件图和装配图的绘制。 对于即将毕业的学生来说，本次设计的最大成果就是：综合运用机械设计、机械制图、机械制造基础、金属材料与热处理、公差与技术测量、理论力学、材料力学、机械原理、计算机应用基础以及工艺、夹具等基础理论、工程技术和生产实践知识。掌握机械设计的一般程序、方法、设计规律、技术措施，并与生产实习相结合，培养分析和解决一般工程实际问题的能力，具备了机械传动装置、简单机械的设计和制造的能力。 关键词：齿轮啮合 轴传动 传动比 传动效率 Abstract Gear is one of the most widely used modern machinery transmission mode. It consists of gears, shafts, bearings and boxes of gear, for the original motivation and work machine or between institutions, their matching speed and torque. Gear reducers are characterized by high efficiency, long life, easy maintenance, and has wide application. Design about belt conveyor drive unit – two-stage cylindrical gear reducer of the design process. First drive review of the programme, as gear select gear reducer, and then design and calculation of reducer (including select, design, gear, shaft structure of motor rolling bearing design, select and check, check ping, select and check the coupling key connections, select the gear and bearing lubrication of parts). Used AutoCAD software for two-dimensional plane design of gear reducer, complete gearbox detail drawing and Assembly drawing a two-dimensional plane. For graduate students, the greatest achievement was the design of: integrated use of fundamentals of machine design, mechanical drawing, machine-building, metal materials and heat treatment, tolerance and technology measurement, principles of mechanics, mechanics of materials, machinery, fixtures, computer application Foundation, and technology, engineering technology and production practice of basic theory knowledge. Master the General procedure, method of mechanical design, design, law, technical measures, and with a combination of practice, cultures abili
