内容简介：

邵阳学院毕业设计（论文）内容提要内燃机的发明，带动了汽车的发展，给世人在“行”上带来极大的便利，使得窨距离缩小，人们的工作速度得以提高。内燃机是发动机的一种。发动机是把某种形式的能转变为机械能的机器。发动机是汽车、拖拉机、飞机和船舶等动力机械的动力之源，是它们的“心脏”，其性能是决定这些机器使用性能好坏的关键。往复式发动机由于受自身结构的限制，已经不太适用于高转速、大功率的工作场合。通过对往复式发动机与旋转式发动机的结构特点与工作原理进行对比分析后。作者试求设计一种能够结合往复式发动机与旋转式发动机特点于一身的新型发动机摆动活塞式发动机。首先，针对摆动活塞式发动机的工作原理进行设计与分析。这种新型发动机既具备传统发动机的曲柄连杆机构，又具备了旋转式发动机的旋转特性。它利用扇形活塞转子在一定角度范围内旋转的摆动，通过活塞销带动曲柄连杆机构的运动，最终将力传到曲轴上作为动力输出。其次，针对摆动活塞式发动机的总体结构进行设计。即主要针对发动机的重要传动机构曲柄连杆机构进行结构分析与设计，其中包括发动机气缸、燃烧室、活塞连杆组以及曲轴等部件的结构设计与分析。最后，借鉴目前广泛使用的发动机辅助机构冷却系统与润滑系统。对冷却与润滑系统的结构及部件进行分析介绍，以致能充分完善发动机的总体结构。关键词：发动机；摆动式发动机；扫气作用；浮式连接；包瓦现象；平衡重Content summaryThe internal combustion engine invention, has led the automobile development, on brings the enormous convenience for the common people in the line, causes the basement distance to reduce, peoples working speed can enhance. The internal combustion engine is the engine one kind. The engine is can transform some kind of form into the mechanical energy machine. The engine is power generator the and so on automobile, tractor, airplane and ships source of power, is they the heart, its performance is decides these machine operational performance qualities the key. The reciprocation type engine as a result of own structure limit, not too is already suitable for the high rotational speed, the high efficiency work situation.Through carries on the contrast analysis after the reciprocation type engine and the rotary system engine unique feature and the principle of work. The author tries to ask to design one kind to be able to unify the reciprocation type engine and the rotary system engine characteristicswings the piston engine in a body new engine.First, in view of swings the piston engine principle of work to carry on the design and the analysis. This kind of new engine both has the traditional engine crank link motion gear, and has had the rotary system engine turning performance. It uses the fan-shaped piston rotor in certain angle scope internal rotation swinging, through the piston pin impetus crank link motion gear movement, finally passes to the strength on the crank to take the dynamic output.Next, in view of swings the piston engine overall structure to carry on the design. Namely mainly aims at the engine the important transmission system crank link motion gear to carry on the structure analysis and the design, including part and so on engine cylinder, combustion chamber, piston linkage as well as crank structural design and analysis.Finally, model at present widespread use engine auxiliary body cooling system and lubrication system. To cools carries on the analysis introduction with the lubrication system structure and the part, so that can fully consummate the engine the overall structure.Key word：Engine；Oscillating engine；Sweeps is mad the function；Floating type connection；Package of tile；Phenomenon Counterbalance目 录内容提要IContent summaryII1 前言1 1.1 内燃机的概述1 1.2 选题的背景2 2 往复发动机基本工作原理3 2.1 二冲程发动机工作原理及换气过程3 2.2 四冲程发动机工作原理4 3 摆动活塞式发动机工作原理6 3.1 工作原理63.2 曲柄摇杆机构传动分析94 摆动活塞式发动机结构设计124.1 传统发动机的组成结构介绍124.2 曲柄连杆机构的设计12
