摘要
 
 液壓泵是向液壓系統提供一定流量和壓力的油液的動力元件,它是每個液壓系統中不可缺少的核心元件,合理的選擇液壓泵對于液壓系統的能耗﹑提高系統的效率﹑降低噪聲﹑改善工作性能和保證系統的可靠工作都十分重要
 本設計對軸向柱塞泵進行了分析,主要分析了軸向柱塞泵的分類,對其中的結構,例如,柱塞的結構型式﹑滑靴結構型式﹑配油盤結構型式等進行了分析和設計,還包括它們的受力分析與計算.還有對缸體的材料選用以及校核很關鍵;最后對變量機構分類型式也進行了詳細的分析,比較了它們的優點和缺點.該設計最后對軸向柱塞泵的優缺點進行了整體的分析,對今后的發展也進行了展望.
 
關鍵詞: 柱塞泵,液壓系統,結構型式,今后發展.
  

Abstract

 Liquid's pressing a pump is the motive component of oil liquid which presses system to provide certain discharge and pressure toward the liquid, it is each core component that the liquid presses the indispensability in the system, reasonable of choice liquid's pressing a pump can consume a ﹑ exaltation the efficiency ﹑ of the system to lower a Zao voice ﹑ an improvement work function and assurance system for liquid pressing system of of dependable work all very important
 This design filled a pump to carry on toward the pillar to the stalk analytical, mainly analyzed stalk to fill the classification of pump toward the pillar, as to it's win of structure, for example, the pillar fill of the ﹑ slippery Xue structure pattern ﹑ of the structure pattern went together with the oil dish structure pattern's etc. to carry on analysis and design, also include their is analyze by dint with calculation.The material which still has a body to the urn chooses in order to and school pit very key;Finally measure an organization classification towards change, the pattern also carried on detailed analysis and compared their advantage and weakness.That design end filled the merit and shortcoming of pump to carry on whole analysis toward the pillar to the stalk and also carried on an outlook to aftertime's development.
Keyword: The pillar fills a pump, the liquid presses system, structure pattern, will develop from now on.
