毕业论文斜轴式轴向柱塞泵的设计摘要轴向柱塞泵作为应用广泛的一类柱塞泵，它的柱塞轴线与缸体轴线相互平行。因为结构紧凑的原因使它具有较为明显的优点，具有紧凑的结构、较轻的重量、单位功率体积小、较高的工作压力以及较高的容积效率。轴向柱塞泵在机械工业，特别是在液压系统中有着广泛的应用。本次毕业设计是对斜轴式轴向柱塞泵进行的设计，其主要性能参数为额定压力 Pn =32MPa，理论排量 v=28ml/r，转速 n=1450r/min。本文将对斜轴式轴向柱塞泵的发展状况、应用现状、轴向柱塞泵的研究现状以及工作原理进行一定的阐述。根据已知参数对连杆柱塞组、缸体、配流盘、主轴等进行设计计算。着重进行连杆柱塞组、配流盘的受力分析，轴承的选择与校核，平键的强度校核。根据计算得到的相关参数绘制三维零件图以及三维装配图。关键词：柱塞泵 柱塞 缸体 配流盘The Design of Bent Axis Axial Piston PumpAbstractAxial 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. 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 . Draw three-dimensional assembly drawing and parts drawing in accordance calculated parameters .Key Words : plunger pump;plunger; cylinder; valve plateIV目 录1.引言 .11.1 研究基础 .11.2 斜轴式轴向柱塞泵的特点 .11.3 国内外发展现状 .22.A2F 型斜轴式轴向柱塞泵的结构及工作原理 .32.1 斜轴式轴向柱塞泵的结构 .32.2 斜轴式轴向柱塞泵工作原理 .33.A2F 斜轴式轴向柱塞泵的基本参数 .53.1 容积效率 .53.2 机械效率 .53.3 功率与效率 .64.主要零件的设计计算 .74.1 连杆柱塞组的设计 .74.1.1 柱塞直径 dz .74.1.2 柱塞名义长度 .84.1.3 连杆球头直径 .84.1.4 连杆设计 .84.2 配油盘的设计 .104.2.1 过渡区设计 .104.2.2 配油盘主要尺寸确定 .114.3 缸体的设计 .124.3.1 柱塞分布圆半径 Rf.134.3.2 缸体内外直径 D1,D2 的确定 .134.3.3 缸体的高度 .144.4 球面配流副的设计 .144.4.1 缸孔油窗口倾斜角 的确定 .1504.4.2 球面半径 R 的确定 .16nts
