简摆式颚式破碎机是如何构造的
它可以制造成大、中型破碎机，破碎坚硬的矿石或物料，其破碎比是3-6.
以沈阳重型机器厂制造的简摆型颚式破碎机为例说明其结构。
破碎机机架上的前壁即是固定颚，为了防止它磨损。在其上面安装有定颚衬板2，中心轴4的两段分别支承在轴承上。轴上则悬挂着动颚5及动颚衬板6，偏心轴8支承在主承轴上，而偏装有连杆头9，连杆头和杆身分开制造，然后用螺栓把紧成一体，连杆头里面通过循环冷却水，用以冷却连杆头的轴瓦，电动机三角皮带轮，通过皮带带动固定的偏心轴上的轴瓦。使偏心轴转动，在杆身下方两侧的凸槽中，装有肘板头11，前、后推力板12和13的一端支承在肘板头上，
拉杆15拉着动颚下端的耳环，其另一端通过弹簧16支持在机架的后壁上，当动颚向前摆动完成之后，转向后退时，动颚和推力板所产生的惯性力。通过拉杆由弹簧来平衡。所以能使动颚、推力板、连杆保持紧密接触而不产生冲击。另外连杆15还从滚筒下方拖着，避免了拉杆被弹簧托盘磨坏。
偏心轴除在一端固定有皮带轮10之外，在另一端还固定着飞轮，皮带轮同时也起飞轮的作用，在破碎机的空行程中，飞轮贮存能量，而在工作中释放出来，从而可以减轻偏心轴旋转的速度的不均匀使电动机的功率输出稳定均衡。
在后推力板的后肘板与后承座之间，放置一组衬垫，用以调节排料口的大小，当增加衬垫的厚度时，可使动颚向前移动一个距离。排料口缩小，反之，如减小衬垫的厚度，则可以使排料口相应增大。

Simple pendulum jaw crusher is how to construct the

它可以制造成大、中型破碎机，破碎坚硬的矿石或物料，其破碎比是3-6.

It can be made into large, medium - sized, broken, hard ore or material, its crushing ratio is 3-6.

A simple pendulum type jaw crusher made by Shenyang heavy machinery factory is a case study of the structure of the machine.

破碎机机架上的前壁即是固定颚，为了防止它磨损。在其上面安装有定颚衬板2，中心轴4的两段分别支承在轴承上。轴上则悬挂着动颚5及动颚衬板6，偏心轴8支承在主承轴上，而偏装有连杆头9，连杆头和杆身分开制造，然后用螺栓把紧成一体，连杆头里面通过循环冷却水，用以冷却连杆头的轴瓦，电动机三角皮带轮，通过皮带带动固定的偏心轴上的轴瓦。使偏心轴转动，在杆身下方两侧的凸槽中，装有肘板头11，前、后推力板12和13的一端支承在肘板头上，

The front wall of the crusher frame is fixed jaw, in order to prevent it from wearing. In its upper part of the installation of a fixed jaw plate 2, two of the central axis of the 4 segments were supported on the bearing. Shaft is hanging moving jaw and the movable jaw lining board 6, eccentric shaft is supported in the main bearing shaft, and is provided with a connecting rod head 9, connecting rod head and the rod body separated from manufacturing and bolts to tightly into a whole, connecting rod head through the circulating cooling water, to cooling connecting rod head, bearings, motor V-belt wheel, driven by a belt fixed eccentric shaft bearing. The eccentric shaft is rotated, and the top 11 of the elbow plate is arranged on the convex groove in the lower side of the rod body, and the front and rear thrust plate 12 and 13 are supported on the elbow plate,

拉杆15拉着动颚下端的耳环，其另一端通过弹簧16支持在机架的后壁上，当动颚向前摆动完成之后，转向后退时，动颚和推力板所产生的惯性力。通过拉杆由弹簧来平衡。所以能使动颚、推力板、连杆保持紧密接触而不产生冲击。另外连杆15还从滚筒下方拖着，避免了拉杆被弹簧托盘磨坏。

The pull rod 15 is pulled at the end of the movable jaw, and the other end is supported on the rear wall of the frame by the spring 16, and the inertia force generated by the movable jaw and the thrust plate when the movable jaw is moved forward. The tension rod is balanced by the spring. So it can make the moving jaw, thrust plate, connecting rod to maintain close contact without impact. In addition, the connecting rod 15 is pulled from the bottom of the roller, to avoid the tension rod is worn by the spring tray.

偏心轴除在一端固定有皮带轮10之外，在另一端还固定着飞轮，皮带轮同时也起飞轮的作用，在破碎机的空行程中，飞轮贮存能量，而在工作中释放出来，从而可以减轻偏心轴旋转的速度的不均匀使电动机的功率输出稳定均衡。

In addition, the eccentric shaft is fixed at one end of the belt wheel 10, the other end is fixed with a flywheel, the belt wheel also plays a role in the air travel, the flywheel storage energy, and the release of the work, which can reduce the speed of eccentric shaft rotation to make the motor power output stable equilibrium.

在后推力板的后肘板与后承座之间，放置一组衬垫，用以调节排料口的大小，当增加衬垫的厚度时，可使动颚向前移动一个距离。排料口缩小，反之，如减小衬垫的厚度，则可以使排料口相应增大。

Between the rear thrust plate and the rear bearing seat, a set of pads are positioned to adjust the size of the discharge hole, and when the thickness of the liner is increased, the moving jaw can move a distance. The discharging port is reduced, and the other is, if the thickness of the lining is reduced, the discharging port corresponding increase.
