手动变量柱塞泵装配图-A0
摘要
轴向柱塞泵（英文名：Piston pump）在机械行业中运用是相当广泛的,特别是履带行走的机械,如履带式修路机、柏油铺路机、甘蔗收割机、番茄收割机等,都广泛用到这类泵体.特别是这些年来,数控加工得到广泛应用,机械加工工艺得到全面提升,加工成本也得到降低,液压行走系统也越来越被一些机械设计人员所接受和选择,抛弃了传统的机械传递,改为了结构简单,重量轻,设计成本相对较低的液压系统.即提高了其机具的档次.也增加了产品的竞争力.
该类泵其原理是依靠柱塞在缸体中往复运动，使密封工作容腔的容积发生变化来实现吸油、压油,从而将机械能转化成液压能,将带有一定压力和流速的液压油传递给液压元件使其做功.轴向柱塞泵具有额定压力高、结构紧凑、效率高和流量调节方便等优点.其中SCY型轴向柱塞泵是可以手动调节输出流量的柱塞泵，其原理为转动手轮使变量活塞上下移动，带动变量头倾斜角变化，改变柱塞行程长短，达到变量的目的。
本设计对10SCY14-1B手动变量轴向柱塞泵对轴向柱塞泵进行了资料的收集和分析,主要分析了该类柱塞泵的结构组成,工作原理,例如,柱塞的结构型式﹑滑靴结构型式﹑配油盘结构型式等进行了分析和设计,还包括这些结构受力情况分析与计算.对缸体的材料选用以及校核,最后对变量机构分类型式也进行了详细的分析,比较了它们的优点和缺点.该设计最后对轴向柱塞泵的优缺点进行了整体的分析,对液压今后对我国军事工业,农业机械等行业产生的深远影响进行分析.

Abstract
Axial piston pump is widely used in machinery industry, especially the crawler machinery, such as Caterpillar road machine, asphalt paver, sugarcane harvester, tomato harvesters etc., are widely used in this kind of pump body. Especially in recent years, is widely used in CNC machining, to improve the machining process, machining cost can be reduced, the hydraulic driving system is also more and more by some mechanical design personnel to accept and choose, abandon the traditional mechanical transmission, to has the advantages of simple structure, light weight, hydraulic system design and relatively low cost. Improve the equipment level. Also increased the competitiveness of their products
This type of pump and its principle is to rely on the piston reciprocating in the cylinder motion, make volume sealed working chamber to change oil, oil pressure, thereby converting the mechanical energy into hydraulic energy, hydraulic fluid with certain pressure and flow velocity is transferred to the hydraulic element to make it work. Axial plunger pump with a rated pressure, compact structure, high efficiency and flow and easy adjustment. The SCY type axial plunger pump plunger pump can be manually adjusted output flow, its principle is the variable rotate the handwheel piston to move up and down, driving the variable head tilt angle change, change the plunger stroke length, to achieve variable objective.
The design of the 10SCY14-1B manual variable axial plunger pump for data collection and analysis of axial piston pump, the main components of the structure, the principle of the piston pump, for example, structure type, piston slipper structure, plate structure is analyzed and designed, including analysis and calculation the force of these structures. To block the material selection and verification, the variable mechanism type are also analyzed in detail, and compares their advantages and disadvantages. The final design of axial piston pump the advantages and disadvantages of the overall analysis, the future of China hydraulic industry, analyzed influence of agricultural machinery and other industries
