【正文】 ，液壓缸的設(shè)計(jì)包括了系統(tǒng)工作壓力的選定、液壓缸內(nèi)徑和外徑的確定、活塞桿直徑和 活塞直徑的確定、液壓缸壁厚的計(jì)算、缸蓋厚度的確定、缸體長(zhǎng)度的確定、緩沖裝置的計(jì)算以及活塞桿穩(wěn)定性的驗(yàn)算。本設(shè)計(jì)應(yīng)用經(jīng)驗(yàn)設(shè)計(jì)法和計(jì)算機(jī)輔助工程技術(shù)完成，先依據(jù)經(jīng)驗(yàn)公式計(jì)算，確定了液壓缸安裝方案，設(shè)計(jì)了液壓缸活塞及活塞桿尺寸參數(shù)，校核匹配的連接螺栓、銷軸等。最后用繪圖軟件 CAD完成液壓缸裝配圖。 關(guān)鍵詞：叉車、提升液壓缸、液壓缸設(shè)計(jì) I Abstract ABSTRACT This is the subject of internal bustion forklift lifting hydraulic cylinder design, the hydraulic cylinder design including the working pressure of the system is selected, the hydraulic cylinder inner diameter and outer diameter of the piston rod and the piston diameter, diameter determination, hydraulic cylinder wall thickness calculation to determine the thickness of the cylinder block, cylinder head, length, buffer device is calculated and the piston rod stability checking. Design and application of the experience design method and puter aided engineering technology, according to the empirical formula, determine the hydraulic cylinder installation project, design of hydraulic cylinder piston and piston rod size parameters, check matching bolt, pin. Finally with the drawing software CAD plete hydraulic cylinder assembly drawing.
