摘 要由于顎式破 碎機(jī)具有結(jié)構(gòu)簡(jiǎn)單、制造容易、 維護(hù)方便、工作可靠等特點(diǎn)。所以 ，世界各國(guó)在冶金、化工、建筑材料 、礦工等基礎(chǔ)工業(yè)部門都廣泛采用這種設(shè)備。復(fù)擺顎式破碎機(jī)結(jié)構(gòu)簡(jiǎn)單，制造容易、工作可靠、使用維修方便，所以常見的還是傳統(tǒng)的復(fù)擺顎式破碎機(jī)。 根據(jù)要求我 設(shè)計(jì)了復(fù)擺顎式破碎機(jī)，其工作 原理是：工作時(shí)，電動(dòng)機(jī)通過(guò)皮帶 輪帶動(dòng)偏心軸旋轉(zhuǎn)，使動(dòng)顎周期地靠近 、離開定顎，從而對(duì)物料有擠壓 、搓、碾等多重破碎，使物料由大變小 ，逐漸下落，直至從排料口排出。 設(shè)計(jì)內(nèi)容主 要包括了復(fù)擺顎式破碎機(jī)的動(dòng)顎 、偏心軸、皮帶輪、動(dòng)顎齒板等一 些重要部件；另外對(duì)顎式破碎機(jī)的工 作原理及特點(diǎn)和主要部件作了介紹；同時(shí)對(duì)機(jī)器參數(shù)（主軸轉(zhuǎn)速、生產(chǎn)能力、破碎力、功率等）作了計(jì)算。 關(guān)鍵詞：復(fù)擺顎式 破碎機(jī)；偏心軸；動(dòng)顎Abstract Due to the jaw crusher is simple in structure, easy to manufacture, convenient maintenance work reliable. So, the world in metallurgy, chemical industry, buildi ng materials, miners and other basic industry departments are widely used this kind of equipment. Pendulum jaw crusher structure is simple, make easy, reliable and convenient usage and maintenance, so common or traditional pendulum jaw crusher.According to the request I designed the pendulum jaw crusher, the working principle is: work, motor drive shaft rotation by pulley eccentric, make the move to close to leave, jaw cycle for jaw, and the material is extrusion, rolling, grinding multiple broken, make the material is bigger or smaller, gradually whereabouts until from discharging mouth eduction.Design content mainly includes the pendulum jaw crusher dynamic jaw, eccentric shaft, pulley, dynamic jaw teeth board some important parts; In addition to jaw crusher work principle and characteristics and main parts is introduced; At the same time for the machine parameters (spindle speed, production capacity, crushing strength, power, etc.) for the calculation.Key words: pendulum jaw crusher; Eccentric shaft; Move jaw 目 錄 摘 要 1 Abstract 2 前 言 . 1 第一章 緒論 3 §1.1 顎式破碎機(jī)簡(jiǎn)介 .§1.2 復(fù)擺式顎式破碎機(jī)的特點(diǎn) §1.3 礦石的破碎及力學(xué)性能 .§1.4 破碎工藝 . 10 第二章 設(shè)計(jì)任務(wù)及要求 11 §2.1 設(shè)計(jì)條件 . 11 §2.2 設(shè)計(jì)內(nèi)容 . 11 §2.3 設(shè)計(jì)要求 . 11 第三章 基本結(jié)構(gòu)及工作原理 13 3.1 基本結(jié)構(gòu) . 13 3.2 工作原理 . 13 第四章 參數(shù)的選擇和計(jì)算 15 §4.1 顎式破碎機(jī)的結(jié)構(gòu)及運(yùn)轉(zhuǎn) 15 §4.2 結(jié)構(gòu)參數(shù)的選擇 . 15 §4.3 主要參數(shù)的計(jì)算 . 20 第五章 主要零部件結(jié)構(gòu)尺寸的計(jì)算與選擇 28 §5.1 電動(dòng)機(jī)功率的計(jì)算與選擇 28 §5.2 皮帶及帶輪的設(shè)計(jì) . 32 §5.3 偏心軸的設(shè)計(jì)計(jì)算 37 §5.4 軸承的選擇與校核 . 43 §5.5 平鍵的選擇及校核 . 46 結(jié) 術(shù) 語(yǔ) . 50 參考文獻(xiàn) . 51 致 謝 52
