1、一 设计题目：铰链式颚式破碎机方案分析二 已知条件及设计要求2.1 已知条件 图1.1 六杆铰链式破碎机 图1.2 工艺阻力 图1.3 四杆铰链式破碎机图(a)所示为六杆铰链式破碎机方案简图。主轴1的转速为n1 = 170r/min，各部尺寸为：lO1A = 0.1m, lAB = 1.250m, lO3B = 1m, lBC = 1.15m, lO5C = 1.96m, l1=1m, l2=0.94m, h1=0.85m, h2=1m。各构件质量和转动惯量分别为：m2 = 500kg, Js2 = 25.5kgm2, m3 = 200kg, Js3 = 9kgm2, m4 = 200kg,

2、Js4 = 9kgm2, m5=900kg, Js5=50kgm2, 构件1的质心位于O1上，其他构件的质心均在各杆的中心处。D为矿石破碎阻力作用点，设LO5D = 0.6m，破碎阻力Q在颚板5的右极限位置到左极限位置间变化，如图(b)所示，Q力垂直于颚板。图(c)是四杆铰链式颚式破碎机方案简图。主轴1 的转速n1=170r/min。lO1A = 0.04m, lAB = 1.11m, l1=0.95m, h1=2m, lO3B=1.96m，破碎阻力Q的变化规律与六杆铰链式破碎机相同，Q力垂直于颚板O3B，Q力作用点为D，且lO3D = 0.6m。各杆的质量、转动惯量为m2 = 200kg,

3、Js2=9kgm2，m3 = 900kg, Js3=50kgm2。曲柄1的质心在O1 点处，2、3构件的质心在各构件的中心。2.2 设计要求试比较两个方案进行综合评价。主要比较以下几方面：1. 进行运动分析，画出颚板的角位移、角速度、角加速度随曲柄转角的变化曲线。2. 进行动态静力分析，比较颚板摆动中心运动副反力的大小及方向变化规律，曲柄上的平衡力矩大小及方向变化规律。3. 飞轮转动惯量的大小。三 机构的结构分析3.1六杆铰链式破碎机六杆铰链式粉碎机拆分为机架和主动件，构件组成的RRR杆组，构件组成的RRR杆组。+3.2四杆铰链式破碎机四杆铰链式破碎机拆分为机架和主动件，构件组成的RRR杆组。
