星轮减速器抽油机设计_毕业论文.doc

摘 要 针对常规游梁式抽油机自身结构限制引起的减速箱及电机载荷波动大、电机效率低、结构庞大、安装运输非常不便等问题，可以设计一种星轮减速器抽油机，并采用单曲柄复合平衡方式。星轮减速器具有传动比大、承载能力高、输出扭矩大、效率高、体积小等特点, 并可长期运行。 本文首先讲述了星轮传动技术的基本知识，包括基本原理、传动特点、相关计算和应用，然后研究了星轮传动抽油机的设计计算：主要由总体方案确定、运动分析、载荷计算、扭矩计算、主要零部件强度校核等几部分组成；最后简要论证了星轮减速器抽油机的主要优点和发展空间。 关键字：抽油机；星轮减速器；节能；改造  Abstract Aim at the questions of conventional walking beam type pumping unit such as the reduction gear and the electric motor load fluctuates in a big way, the electrical efficiency is low, the structure is huge, the installment and the transportation are inconvenient, we can design a kind of beam pumping unit with planet wheel speed reducer, it has single crank with compound balanced way. Planet wheel speed reducer has the characteristics such as velocity ratio is big, bearing capacity is high, the output torque is big, the efficiency is high, volume is small and it can run in long-term. This paper first elaborated the planet wheel transmission technology, includes basic principle, transmission characteristic, related computation and application. Then studied the design and calculation of beam pumping unit with planet wheel speed reducer .Mainly includes overall plan, movement analysis, the loads analysis, the torque computation, intensity examination of major component. Finally the most advantage and develop opportunitiy of beam pumping unit with a planet wheel speed reducer is demonstrated briefly. Key words: Pumping unit; planet wheel Speed reducer; Energy conservation; improvement 目 录 第 1 章 概述.........................................................1 1.1 机械采油目前存在的问题...................................1 1.2 目前研究现状.............................................2 1.3 本文研究内容.............................................5 第 2 章 星轮传动技术简介.............................................6 2.1 星轮传动技术原理.........................................6 2.2 星轮传动的特点...........................................8 2.3 星轮减速器的设计计算.....................................9
