本帖转自：中国知网论坛:http://www.cnkiw.com
内容提要 液压泵作为液压传动中的一个重要动力装置，在当今工业社会有着相当大的需求量。本文所提到的63CY14-1B型轴向柱塞泵就是其中较常见的一类液压泵。作者通过对作者工作单位——邵阳维克液压有限责任公司，2005-2006年的泵的销售情况讲行调查统计，发现：63CY14-1B型轴向柱塞泵是现在重多使用频率较高的液压泵中的一类。因而选择此型号泵进行改进。本文先从液压泵的基本原理入手，并结合63CY14-1B型轴向柱塞泵自身的特点，相比较介绍，让读者对液压泵有一个初步的认识。然后，分析对于63CY14-1B型轴向柱塞泵哪些地方需要改进，而这些地方又与哪些因素有关联。逐步的说明，改进设计的由来，及其设计步骤。本次对63CY14-1B型轴向柱塞泵的改进，主要是从降低噪音入手。而对于影响63CY14-1B型轴向柱塞泵噪音的3个摩擦副：缸体与配油盘的摩擦、变量头与滑靴的摩擦、柱塞与柱塞孔的摩擦。并对其主要摩擦——缸体与配油盘的摩擦，进行了结构改进。经过实验发现，配油盘上的鼠尾的长度直接影响泵的噪音，于是作者对配油盘上的鼠尾长度经过一系列的实验，最后找到了比较合适的尺寸。在上面所讲的系列实验中，主要采取对比的方法来做。选取了几组缸体与配油盘进行对比实验。本文主要的优点，就是一切从生产实践与试制实验出发，具有很好的应用前景和较好的经济价值。 Summary The hydraulic pump has sizable demand in nowadays industrial society as an important motive equipment in hydraulic transmission. Model 63CY14-1B axial column this text mention fill in pump relatively common first hydraulic pump among them. The author passes author's office correctly - - Shao Yang wei ke Hydraulic Company, Ltd. sales situation of pump for 2005-2006 year speak conduct investigation count, find: Model 63CY14-1B axial column fill in pump serious to use more one kind of high-frequency hydraulic pump now. Therefore choose this type pump to improve. This text proceeds with basic principle of the hydraulic pump first, combine the characteristic of filling in pump of axial column of Model 63CY14-1B, compare the introduction, let readers have a preliminary understanding to the hydraulic pump. Then analyze , fill pump to Model 63CY14-1B axial column what place need improvement , and place these with what factor have something to do , unite. The explanation progressively , the origin designed in improvement, and design the step. Fill axial column of Model 63CY14-1B in the improvement of the pump this time, mainly start with reducing the noise. And fill in 3 of the pump noise to rub pair in influencing the axial column of the Model 63CY14-1B: With mix oil friction , variable head and slippery friction , column of boots of record fill in with column friction to fill hole cylinder block. Find out main friction again - -Cylinder block and mixing the friction of the oil one, improve. Find experiment , mix oil mouse length of tail of plate influence noise of pump directly, then the author passes a series of experiments to the tail length of mouse mixed on the oil plate, found the size suitable finally. Among serial experiment above speak, method compared with to take make mainly. Choose several group cylinder block with mix oil record go on experiment of comparing with. Main advantage of this text, all with trial-produce experiment set out , have good application prospect and better economic worth very from production practices. 目 录 内容提要………………………………………………………………I Summary………………………………………………………………II 前言……………………………………………………………………1 1.1 课题提出的背景和意义…………………………………………1 1.2 国内外研究开发水平和发展趋势………………………………3 1.3 课题研究目标……………………………………………………4 2 液压泵的原理与计算………………………………………………5 2.1液压泵的原理与分类……………………………………………5 2.2 液压泵的性能参数………………………………………………6 2.3 轴向柱塞泵的名称由来与特点…………………………………8 3 泵的噪音来源与改进……………………………………………..13 3.1噪音来源分类……………………………………………………13 3.2摩擦副影响因素…………………………………………………14 3.3噪声改进方法……………………………………………………17 4 轴向柱塞泵结构改进前后 ………………………………………23 4.1 结构与工艺的改进 …………………………………………… 23 4.2进口泵与本土泵的比较……………………………………………23 4.3结构改进方向……………………………………………………23 总 结……………………………………………………………… 26 参考文献…………………………………………………………… 27 致 谢……………………………………………………………… 28 |
