毕业设计（论文）-往复式给料机的设计【全套图纸】.doc

摘 要 本课题的研究内容是给煤机的总体设计。 本论文论述的给煤机是矿山机械的一个部分。给煤机工作的好坏，取决于给煤机的型号，结构和相关参数。首先，通过计算机软件Visual Basic来进行模拟曲柄滑块机构的运动设计编程来确定的给煤最大速度和加速度；其次，以力学模型为依据，分析了减速器的轴、齿轮,托辊上载荷的作用机理，得到了较为合理的给煤机载荷的计算公式；再次，结合本次设计的给煤机，从平面和空间两方面对减速器的轴、齿轮；托辊等主要结构件进行受力分析；最后对减速器的轴、齿轮；托辊等主要结构件进行强度效核，并画出它们的机械工程图， 在完成本设计的过程中，利用理论分析的同时，也采用了许多实际经验，做到理论与实践相结合。 关键词：给料机；减速器；曲柄滑块机构；力学特征；强度 全套图纸，加153893706 ABSTRACT The paper mainly foused on the problem which is design out a type of solution. The solution described is a part of the mining industry equipment in the mine, used for solution of working environment in the locale. It works well or bad at work basing on its solution mode, frame and some parameters. In the first step, the most pace value and acceleration value of some parameters of the Slider-crank Mechanism are determined by using Visual Basic; Secondly, Then on the base of d model of work-surrounding, the load in is decided. The clear in reason expressions of account of solution loading; The next work, with the condition of the design, it is analyzed and calculated by plane and spatial model to the main mechanics of the shaft and gear of the reducer, idler and so on. Finally, it is analyzed by calculation to the main mechanics of the shaft and gear of the reducer, idler and so on. And draw out all the process drawings. During the course of doing the paper, author not only analyses something theoretical, but also adopted a lot of actual experiences. Combining theory and practice. Therefore, the paper possesses theory and practical value, so it measures up the requiring of the nation to the undergraduate. Key words: solution; reducer; Slider-crank Mechanism; mechanics characteristics; strength 目 录 摘 要 1 ABSTRACT 2 1、往复式给料机的概述 4 1.1 K型往复式给煤机的用途 5 1.2 K型往复式给煤机的组成 5 1.3 K-4型往复式给煤机的技术参数 5 2、往复式给料机的结构设计 8 2.1给煤机的大小 8 2.2能量耗损的分析 10 ３、减速器的设计 13 3.1电动机的选型 13 3.2传动比的分配 15 3.3计算传动装置的运动和动力参数 15 3.4齿轮的设计 16 3.5传动轴的设计 29 3.5.4键的强度校核 45 3.5.5 轴承的校核 46 3.6减速器箱体的结构设计 50 3.7轴承盖选用螺钉联接式轴承盖 52 3.9封油垫材料 57 4、给煤机的零件设计 58
