题目： 斜轴式轴向柱塞泵结构设计 PAGE II 摘 要 随着工业的发展，对泵部件的需求越来越多，轴向柱塞泵作为一种柱塞泵被广泛应用，其柱塞轴和柱轴相互平行。由于它具备结构紧凑，重量轻巧，体积较小，工作压力较大，体积效率高等特点。轴向柱塞泵普遍应用在机械行当，主要在是液压系统[1]。 本文主要对斜轴式轴向柱塞泵进行整体构造的设计。首先，对斜轴式柱塞泵的总体构造进行设计，对它的发展现状以及工作过程进行阐明；其次，对其主要零件进行设计计算，包括连杆柱塞组件的设计计算、配油盘设计计算、缸体的设计计算等；最后，根据设计出来结构，利用Pro/e软件对其进行三维模型的绘制，利用AutoCAD对二维的装配图和零件图进行绘制。操纵Fluent模拟软件，给斜轴柱塞泵的设计做了一个简单的流体模拟。结果表明，此次斜轴式柱塞泵的设计对生产具定参考作用和借鉴作用。 关键词：柱塞泵；柱塞；缸体；配流盘；结构优化 全套图纸加扣 3346389411或3012250582 ABSTRACT Axial piston pump is widely used as in mechanical industry , its position axis parallel to the cylinder axis. It has many obvious the advantages due to its compact structure, such as light weight, small size, power units, high working pressure and high volume efficiency. Axial piston pump has been widely used in the machinery industry, especially in the hydraulic system .The graduation project is to design Cline axial piston pump, the main performance parameters is given, its nominal pressure is 32MPa, the theoretical displacement is 28ml / r, speed is 1450r/min[2]. In this paper, there are some exposition about the development status of Bent Axis Piston Pumps, application status, the status of research and how is the axial piston pump works . Based on the given parameters,I will do some calculations on the plunger rod group, cylinder, valve plate, and spindle . Be focused on the check of plunger rod group, valve plate stress analysis, bearing selection and verification, and flat key strength[3]. Draw three-dimensional assembly drawing and parts drawing in accordance calculated parameters .
