当破碎机工作时，飞轮8带动偏心轴6转动，由于偏心轴的偏心作用，悬挂在它上边的可动颚板2在推力板9的制约下，相对于固定颚板往复地做一种复合摆动运动。
实际上复摆式可动颚板的运动相当于简摆式破碎机中垂直连杆的运动。
当可动颚板2靠近固定颚板3时，物料被破碎。
在破碎过程中，当可动颚板被推向前方时，拉杆12末端的弹簧13即受压缩，由于弹簧企图恢复原状，因此可以帮助可动颚板后退至原来位置。
水平拉杆的作用还在于阻止当可动颚板作返回运动时推力板9不致脱落。

凿岩和颚式破碎机简介中英文翻译
Rock Drilling And Jaw Crusher ProfileEdited by Alan L. HitchcoxRock drilling is all about power and speed. You need a lot of power to break into solid rock and high speed to repeatedly hammer away at a work site. For safety and high productivity, many of today’s machines feature remote control. This presents a challenge because the remote control must be easy to operate yet allow full functionality of the machine.Top hammer percussive drilling —the most common method for drilling holes up to 140 mm diameter —hammers the rock with impacts transferred from the rock drill to a drill bit in the bottom or a hole. Hydraulic pressure generates the force required —pressure builds to a maximum and when released, drives an impact piston forward. When the piston strikes a chuck, it transfers its kinetic energy as a stress wave through a drill rod to the drill bit, which uses this impact energy to pulverize the rock. Obtaining the highest drilling productivity and economy requires operation of all components in the system to be highly synchronized. Design criteriaWhen designing the hydraulic system for a rock drill rig, the operator must be given complete and independent control of the key parameters —percussion pressure, percussion frequency, feed force, and rotation —to achieve optimum drilling efficiency. When all of these parameters are optimized to suit working conditions, the drill bit has full contact with the rock and the shock wave captures maximum kinetic energy to ensure that each impact achieves high productivity.Although the design of the machine itself accounts for much of the machine’s productivity, achieving maximum productivity to meet cost targets requires a well-engineered hydraulic system with components that can maintain high reliability even in the face of frequent heavy impacts. Furthermore, a precise remote control is needed to achieve the high synchronization necessary for maximum productivity. Remote control also provides higher visibility, controllability, and safety than machine-mounted controls. It also lends itself to data acquisition to monitor operation and aid in improving future design of machines.Nimco Controls AB, Malmo, Sweden, developed a system to meet these criteria in drill rigs manufactured by KG Mekaniska AB, Karl Gustav, Sweden. The electrohydraulic system integrates the features of Nimco’s Easy- Prog CANbus-based remote-control system with its CV 2000 LS series pressure-compensated valve. As a result, drill rigs have produced optimal results over the last two years.The electrohydraulic system consists of a variable-displacement pump with load sensing to improve energy efficiency of the system, the CV 2000 LS pressure-compensated valve, and the EasyProg CANbus system. Designers also made an effort to reduce the amount of hydraulic hose in the machine. Not surprisingly, then, the new design contains about 13 less hose. Component detailsThe CV 2000 LS valve can accommodate a flow of 125 lpm to each cylinder port and is designed to work with both fixed- and variable-displacement pumps. Work port flow is controlled by 12- or 24-V proportional solenoids, with manual hand lever override functions available. Pressure limiters can be fitted on each individual work port together with shock and/oranticavitation valves.The EasyProg control is a PC-based system that can be programmed in modules; hardware can also be built in modules to suit requirements of the application. Its CANbus configuration allows for digital and analog inputs and outputs. It features an easy-to-use menu for entering all settings and standard functions. Automatic functions for drill rigs, for example, enhance the speed of parameter settings as well as ensure specific safety parameters.The CV 2000 LS valve controls key rock drill operating functions, such as percussion pressure and frequency, rotation torque, and feed force. It also controls track drives, positioning, and a hydraulic fan drive. The rock drill in actionTo achieve the best combination of productivity and economy, the operator sets the percussion pressure and frequency, and the control sets rotational speed according to set frequency. The final setting is feed force which is set against the percussion pressure to position the drill bit close to the rock. These settings are all maintained by the CV 2000 LS valve, which has two compensators per spool section — one for each cylinder port.Hydraulic settings are made via the EasyProg electrical remote control unit. Feed force is remotely controlled by the CV 2000 LS pressure compensator through a pilot-operated, electrically controlled proportional relief valve. This enables a continuous setting of the feed force while maintaining the possibility of a second pressure limiter working as an overpressure cutoff valve. The design enables two pressure limiters for one cylinder port and extremely fine, stable pressurecontrol.The valve’s compensators exhibit flat flow/pressure curves and provide a constant flow, regardless of load pressure. The frequency and rotation of the drill bit is harmonized with the precise pressure setting for the feed force. The PL-2000 pressure limiter’s distinct pressure cut-off point ensures that the correct flow is maintained throughout the entire pressure range.The EasyProg drill rig version software has automatic setting functions to help the operator reduce initial setup time. It also contains maintenance and service frequency options that can be accessed remotely by OEMs through a GSM unit that vcan be connected to any mobile phone. Additional functions and portable remote control units can be integrated either by wire or by Bluetooth, which, in the new version, has a range of 100 m.Recently, we have talked about rock drilling , the general mining machinery. Of course, there is just a simple talk. So that we have to understand. Next, I introduce a further, the mining machinery in the other a mechanical - jaw crusher.The BR550JG-1 jaw crusher — from Komatsu America International Co. —includes fully hydraulic tracked travel and crushing systems. Powered by Komatsu's 306-hp SAA6DI25E-2 engine, this crusher has a material-output range from 110 to 507 tons per hour, with adjustable open-side discharge settings from 2.2-to8-in.Thesecapacities make the machine suitable for highway construction, housing development, and tunnel works, as well as quarry, demolition, and excavation applications.The 52-ton self-propelled crusher's high travel speeds (with amaximum of approximately 2 mph), along with its 25% gradeability, allow efficient relocation. And once relocated, it can maneuver itself into tight quarters and start to operate immediately, processing a variety of materials — including concrete debris and hard rock.The Komatsu designed and built 30- x 44-in., single-toggle jaw is driven hydraulically with a PC800 LSHT variable-displacement motor via a V-belt. Its speed range — from 210 to 300 rpm — helps to adjust the jaw to the materials to be crushed. The closed-loop crusher control incorporates Komatsu's patented Hydraumind technology to optimize efficiency. Through a combination of load-sensing and pressure-compensated valves, the HydrauMind hydraulic control and monitoring system supplies the appropriate flow of oil to each function. Simultaneously, it identifies potential overloads and automatically slows down the vibratory grizzly infeed's gear-type motor before the overloads become a reality. A pressure dial on the control can be set for anticipated rock hardnesses to work hand in hand with the Hydraumind system. The hydraulic design also allows the crusher to start from a stopped position, even when fully loaded, and it has a reverse-rotation function to help remove bridged or plugged material from the jaw chamber.A 42-in. wide discharge conveyor — driven by another LSHT piston-type motor — carries material away from the jaw chamber.For more versatility, the crusher can be operated from its on-board control station with hydraulic-excavator-type levers, or from ground level or the excavator or loader cab via an optional radio remote control. The remote control operates all travel functions, feeder on/off, jaw on/off, engine auto decelerate, emergency stop, and even the horn.Above, we will rock drilling machine with jaw crusher work processa simple introduction. These elements operate, or who want to redesign the staff is not enough. Described here only, just a small part of the mining machinery. If the reader wanted to know more about mining machinery knowledge, but also need to read more specialized information.翻译凿岩和颚式破碎机简介由艾伦· L.Hitchcox 编辑凿岩是所有关于力量和速度。
颚式破碎机的设计-答辩稿
5、拉紧装置
拉紧装置由弹簧、拉杆及调节螺母 等组成。拉杆的一端绞接在动颚底部， 另一端穿过机架壁的凸耳，用弹簧及螺 母张紧。用拉紧机构使推力板与动颚、 顶座之间保持紧密接触。在动颚工作行 程中，弹簧受到压缩；在卸料行程中， 弹簧伸张。拉杆借助弹簧拉力来平衡动 颚和推力板向前摆动时的惯性力，使动 颚及时向反方向摆动。
6、调节装置
颚式破碎机的出料口宽度，可以通过调节装置来调整。 大、中型颚式破碎机的出料口宽度，是使用不同长度的推力 板来调整的，通过在机后壁与顶座之间垫上不同厚度的垫片 来补偿颚板的磨损。小型破碎机通常采用楔铁调整方法。当 需要调整排料口尺寸时，只要调整楔铁上的螺栓，使楔铁上 下移动，带动调整座在滑道中前后移动即可完成。
3、破碎部件
颚板用于直接破碎物料，为了避免磨损，提高 颚板使用寿命，在颚板和颚腔两侧一般都镶上衬板。 在衬板与颚板之间，常常垫以塑性衬垫，以保持衬板 与颚板紧密结合以及使衬板受力均匀。衬板采用强度 高且耐磨的锰钢铸造。为了有效地破碎物料，衬板的 表面常铸成波浪形和三角齿形。
4、传动机构
偏心轴是颚式破碎机 的主轴，是带动活动颚板 作往复运动的主要部件， 合金钢制造。偏心轴的两 侧分别装有飞轮和带轮， 使动力负荷均匀，破碎机 稳定运转。
n——偏心轴的转速，r／min； s——活动颚板下端水平行程，cm； a——钳角
3、生产能力 颚式破碎机的生产能力 (t／h)与被碎物料的性质(物 料强度、硬度、粒度、堆积密度)有关，还与破碎机的性 能和操作条件(供料情况、出料口大小)等因素有关。目前 广泛应用的是经验公式： 式中： Q—生产能力（m3/h） n—主轴转速（r/min） L—破碎腔长度（m） b—公称排料口尺寸（m） SL—动颚下端点水平行程（m） μ—压碎破碎棱柱体的填充度，中小型机在公称排料口下 一般取0.65～0.75（在此取μ1=0.7）
