【正文】 歷史悠久，這使得大量的研究和實(shí)驗(yàn)工作，都是為了提高軸向柱塞 泵的流量脈動(dòng)，以減少震動(dòng)和噪音，國(guó)內(nèi)和液壓界的科學(xué)工作者研究軸向柱塞泵表明：柱塞泵的實(shí)際流量是受各種因素的影響，流量脈動(dòng)是遠(yuǎn)遠(yuǎn)比理論流量脈動(dòng)大，紋波系數(shù)與柱塞數(shù)的奇偶性無(wú)關(guān)。 關(guān)鍵詞： 軸向柱塞泵，配流盤(pán)，缸體，變量機(jī)構(gòu) 長(zhǎng)沙學(xué)院 畢業(yè)設(shè)計(jì) (論文 ) II ABSTRACT ZCY141B axial piston pump in the hydraulic system, power ponents, axial piston pump is to rely on the plunger (piston chamber) cylinder reciprocating motion, and change the plunger cavity volume suction and discharge of oil,is a positive displacement hydraulic pump. Firstly, the given design parameters obtained distribution on the radius of the diameter of the plunger and backhaul panel plunger size and the force and the empirical formula can draw the basic size of the slipper. Distribution radius in order to determine the valve plate on the inner seal oil, the main dimensions of the suction oil window. Shaft size to calculate the inner diameter of the cylinder, according to the distribution of the plunger and the cylinder wall thickness calculated cylinder diameter, stroke of the plunger to calculate the length of the cylinder, and then check the strength. Finally, the piston pump variable institutions by the line selection, as well as some of the parameters of the calculation, the final assembly of the piston pump. Keywords: Axial piston pump， Valve plate ， Cylinder， Variables agencies 長(zhǎng)沙學(xué)院 畢業(yè)設(shè)計(jì) (論文 ) III 目 錄 摘 要 ........................................................................................................
