颚式破碎机以电动机为动力，通过电动机皮带轮，由三角皮带和槽轮驱动偏心轴，使动颚按预定轨迹作往复运动。

物料在固定颚板，活动颚板和边护板组成的破碎腔内破碎后通过下部的排料口排出。

1、机架部件
颚式破碎机的机架，在工作中受到很大的冲击载荷，因此，它应具有足够的强度和刚度。

机架为焊接件（小型颚破为铸钢件）。

机架的前墙装有用高强度螺栓紧固的固定颚板；机架的左、右内侧壁装有用高强度螺栓紧固的边护板。

2、动颚部件 （1） 结构特征：
动颚为整体优质铸钢结构，其内孔以及凹槽等部位经过精确加工与检测，确保工作时安全、可靠。

偏心轴为优质高强度锻钢，经多次精密的机械加工、热处理和探伤检查制成，因此具有足够的强度和刚度。

轴承采用4套调心滚子轴承，具有良好的承载和自动调心的性能。

活动颚板和固定颚板均为优质高锰钢铸件，为延长其使用寿命，其形状设计成上、下对称，即当一端磨损后可调头使用。

飞轮、槽轮为优质铸铁件，其重量和结构足够保证破碎机能平衡地工作。

飞槽轮在偏心轴上的两端位置可以相互调换，并通过胀紧套或键连接。

（2） 动颚部件装配过程：
a. 偏心轴组件安装。

取偏心轴、轴承二只并用煤油清洗干净，然后将二只挡油盘装于偏心轴两端。

二只轴承置于80-100℃油中加热15分钟左右，测量轴承的内圈孔大于偏心轴轴颈0.15mm 时，取出并热套于偏心轴的两端，施压顶住轴承使之与轴肩靠紧，直到轴承完全冷却为止，其间隙不得大于0.05mm 。

套合后整理清洗干净，在轴承中注入50%-70%润滑脂。

（见图2）
图2 偏心轴组件安装过程
b.偏心轴装入动颚。

装妥动颚一端的透盖、纸垫圈等，并用螺栓紧固。

此时，将动颚孔竖放，使装好透盖的一端朝下，接着将偏心轴装配组件吊入动颚中，注意偏心轴方向，吊装时须注意：偏心轴和动颚同孔中心线保持一致，放正轴承外套，先轻压作好导向，当

压入量均匀渐进时，方可进行连续敲压。

（不能用锤直接敲击轴承，应在轴承上垫放铜棒后，再敲击铜棒）；当第一只轴承压入后装第二只轴承时程序同上。

继后，在轴承中注入50%-70%的润滑脂，最后再装妥另一侧的透盖、纸垫等，并用螺栓坚固。

装妥后应使轴承外圈端面与透盖端面有0.2-0.4的间隙,它是通过装入适量纸垫圈得到的.（见图3）
图3 动颚组件装入动颚孔
c. 外部轴承的安装。

把各个键分别装入偏心轴上的键槽内，再分别装入迷宫内环透盖，注意左右方向，取另外二只轴承，用煤油清洗干净，把紧定衬套放入轴承孔内，再安装于偏心轴上，按结构图旋入圆螺母，止退垫圈。

注意偏心轴上有左、右旋螺纹，目的是偏心轴旋转时应使圆螺母越旋越紧，先旋偏心轴上圆螺母，使之压紧紧定衬套，再旋紧定衬套上的圆螺母，使轴承内圈靠紧密封圈，这样反复数次，最终使轴承紧固，把紧定衬套
上的圆螺母退出，使之与轴承内圈间隙为1mm左右（在拆轴承时，先松掉偏心轴上的圆螺母再旋紧紧定衬套上的圆螺母即可把轴承拆下）。

把止退垫圈的长短齿分别压入紧定衬套上的圆螺母和偏心轴上的圆螺母槽内并紧固，然后在轴承中注入50%-70%润滑脂，再分别装入透盖内环。

（见图4）

d. 飞、槽轮的安装
把飞、槽轮及胀紧套（或键）放于偏心轴上，使飞、槽轮与密封圈靠紧，并注意使飞、槽轮上的标记与偏心轴上标记对应后旋紧胀紧套上的螺栓，胀套安装方法按此本手册，然后装妥轴端挡圈。

（注意：飞槽轮系铸铁件，安装时切忌热套）槽轮常规是安装在偏心轴左端（面对进料口方向看），也可根据现场需要使飞、槽轮位置进行对调。

（见图5）
图5 飞轮、槽轮的安装（含涨套安装）
3、肘板与调整部件
（1）肘板是经过精确计算的铸铁件。

它不只是传力构件，而且也是破碎机的保险零件。

当破碎机中落入不能破碎的物料而使机器超过平常负荷时，肘板就会立即折断，破碎机停止工作，从而避免整个机器的损坏。

肘板和肘板垫采用滚动接触方式，正常使用情况下很少磨擦，只需在其接触表面上涂上一层润滑脂即可。

肘板损坏后请立即更换，更换方法，请看图6所示。

更换肘板前，请确保有合适的起重设备，并准备合适的钢丝绳。

（2）调整部件是用于调整排料口大小，以及补偿颚板、肘板和肘板垫之间磨损的机构。

1.把带轮（飞轮） 吊装到偏心轴上
2.把涨套压入偏心轴
（预先松开涨套上的螺栓）
3.拧紧涨套上的螺栓，使带轮（飞轮）卡紧，然后装上轴端挡圈

2.启动起重设备向上吊起，使动鄂缓慢旋转直到与定鄂
板靠紧
3.拆掉调整装置和拉紧装置
4.将新肘板吊装到位
5.安装调整和拉紧装置
6.缓慢放下动鄂，使肘板两端顶紧，并适当调整拉紧装置
（3）排料口的调整：
肘板垫通过角钢和螺栓紧固于调整座或动颚上，调整垫片置于调整座与机架之间，并置于支承架，起顶螺栓（或顶头与液压起顶机）通过螺母或可穿过调整垫片顶住调整座，调整座上面通过楔块或直接与机架连接，起顶螺栓或顶头与液压起顶机都可单独起到调整作用。

当调整排料口时，首先适度拧松拉紧部件的拉杆螺母，松开弹簧，然后再松开楔块螺栓，松开楔块，拧紧起顶螺栓，（或把液压起顶机头部装入顶头，旋入机架后的螺母内，将液压起顶机的出油阀打开，扳动手柄）起顶螺栓或顶头向前推动调整座，达到一定的开口度时，取出调整垫片，以达到增大排料口的需要；若放入调整垫片，则可达到减小排料口的需要。

在达到用户所需的排料口尺寸后，首先松开起顶螺栓（可打开液压起顶机的进油阀，扳动手柄，松开顶头）调整座在动颚部件自重的推力作用下，调整座及调整垫片组向机架后墙靠拢，压实，注意起顶螺栓或顶头松开程度应达到调整座向后墙靠拢，压实后而不相接触，再拧紧楔块螺栓，将楔块与调整座与机架牢固，适度拧紧拉杆螺母收紧弹簧，即完成调整排料口工作。

（见图7）
图7 排料口的调整
4、拉紧部件
拉紧部件用以保证破碎机整个机构紧密结合，并能够平衡动颚与肘板在工作时产生的惯性力。

拉紧部件的装配过程：
拉杆的一端铰接于动颚下端的耳环上，另一端通过垫圈支承在机架后墙的下端，弹簧通过其两端的垫圈和螺母压紧。

破碎机工作时弹簧需要一定的预紧力，以防止肘板在工作时脱落，但不宜过大，只要能消除肘板与动颚、调整部件间冲击响声即可，否则将影响弹簧的使用寿命，甚至使弹簧断裂。

5、铁轨部件
铁轨通过地脚螺栓紧固在钢筋混凝土基础上。

电动机安装在铁轨上，支座嵌入铁轨的槽中，根据三角皮带的松紧程度调整电动机与主机的距离，当距离确定后，用紧固在支座上的调整螺钉顶住电动机的底座，以防其走位。

6、安全防护装置
安全防护装置由用户现场制作安装并应加上相应标志。
