燃烧室为涡流室，其下部嵌有杯形涡流室镶块，增压柴油机的涡流室镶块与其他机型不同，更换时应注意。

镶块上开有长形倾斜喷口及锥形起动孔。

安装时此孔应与喷油器油注对应。

进、排气门与气门座在使用时已经走合，拆装时应注意其缸号，不得互换。

当气门于门座密封不良时，应进行研磨，装配前应清洗干净。

经长期使用气门座接触带宽度超过2.5mm时，可用导杆直径为9mm的15度和75度专用铰刀气门座。

必要时可用45度铰刀铰接触带。

若气门下沉量大于3.5mm，必须更换气门座。

气门座与汽缸盖气门座孔配合过盈量为0.086-0.150mm。

装配时应将汽缸盖整体加热至200度左右，然后镶入气门座，并对接触带进行精铰、研磨，使其宽度为1.3-1.5mm，气门下沉量为1.2-1.6mm。

汽缸盖和机体之间装的汽缸盖垫片，用18个螺栓将汽缸盖紧固在机体上。

汽缸盖螺母（螺栓）应按照特定顺序，分三次逐步拧紧到规定力矩。

三、活塞连杆总成活塞连杆总成由活塞、活塞环、活塞销、连杆、连杆轴瓦、连杆螺栓等组成。

柴油机每个活塞装有三道气环和一道油环。

第一道气环为桶面镀铬环，以提高在高温下的耐磨性。

第二道气环为锥面环，打有“上”字一面朝上，不得装反。

第三道气环为扭曲环，带扭曲槽的一面朝下。

油环为带有内撑簧的组合油环。

装配油环时，应注意将撑簧的对口处放在油环开口的对面。

新活塞装配时，应先将环放入缸套内，用塞尺检查开口间隙应在规范范围内，间隙过小应用锉刀修整。

Deere equipment include such items as oil,fuel,coolant,brake fluid,filters,and batteries.Use leakproof containers when draining fluids.Do not use food or beverage containers that may mislead someone into drinking from them.Do not pour waste onto the ground,down a drain,or into any water source.Air conditioning refrigerants escaping into the air can damage the Earth’s ernment regulations may require a certified air conditioning service center torecover and recycle used air conditioning refrigerants.T S 1133—U N —26N O V 90Inquire on the proper way to recycle or dispose of waste from your local environmental or recycling center,or from your John Deere dealer.Avoid Harmful Asbestos DustAvoid breathing dust that may be generated whenhandling components containing asbestos fibers.Inhaled asbestos fibers may cause lung cancer.Components in products that may contain asbestosfibers are brake pads,brake band and lining assemblies,clutch plates,and some gaskets.The asbestos used in these components is usually found in a resin or sealed in some way.Normal handling is not hazardous as long as airborne dust containing asbestos is not generated.Avoid creating dust.Never use compressed air for cleaning.Avoid brushing or grinding material containing asbestos.When servicing,wear an approved respirator.A special vacuum cleaner is recommended to clean asbestos.If not available,apply a mist of oilor water on the material containing asbestos.T S 220—U N —23A U G 88Keep bystanders away from the area.Handle Fuel Safely—Avoid FiresHandle fuel with care:it is highly flammable.Do not refuel the machine while smoking or when near open flame or sparks.Always stop engine before refueling machine.Fill fuel tank outdoors.Prevent fires by keeping machine clean of accumulated trash,grease,and debris.Always clean up spilled e only an approved fuel container for transporting flammable liquids.Never fill fuel container in pickup truck with plastic bed liner.Always place fuel container on ground beforerefueling.Touch fuel container with fuel dispenser nozzle before removing can lid.Keep fuel dispenser nozzle in contactwith fuel container inlet when filling.T S 202—U N —23A U G 88Do not

它的作用是控制气门的开启和闭合动作。

虽然在四冲程发动机里凸轮轴的转速是曲轴的一半（在二冲程发动机中凸轮轴的转速与曲轴相同），不过通常它的转速依然很高，而且需要承受很大的扭矩，因此设计中对凸轮轴在强度和支撑方面的要求很高，其材质一般是特种铸铁，偶尔也有采用锻件的。

毛坯的形状和尺寸的确定，除了将毛坯余量附在零件相应的加工表面上之外，有时还要考虑到毛坯的制造、机械加工及热处理等工艺因素的影响。

在这种情况下，毛坯的形状可能与工件的形状有所不同。

该机采用絮凝技术，将沉降与深层过滤相结合，矿浆直接给入浓缩机的压缩区，在池内形成滤床层，后续给入的矿浆中未絮凝的细小颗粒，随水流上升，途经滤床层，与其中的颗粒碰撞，上升动能损耗，与其它颗粒结合在一起下沉。

从而增加了底流浓度，减少了溢流水浊度。

由于采用了絮凝剂，颗粒形成絮凝团，沉降速度加快，处理能力提高.桥架固定在浓缩池及支柱上，它是维护人员进入浓度机中心部位的通道。

495G汽油机活塞的设计与开发

495G汽油机活塞的设计与开发太原理工大学机械学院　张翠平摘　要简要介绍活塞的工作条件和设计要求,着重介绍495G汽油机活塞的结构特点。

试验结果表明:该活塞满足495G汽油机的性能要求。

关键词:汽油机　活塞　设计495G汽油机是太原理工大学和榆次内燃机厂共同研制开发的新产品,它在492汽油机的基础上进行了扩缸处理。

为此必须重新设计活塞。

新设计的活塞经过反复试制、改进、试验论证和实践考核,证明满足使用性能要求,现已投入生产。

1　活塞的工作条件及设计要求活塞是内燃机中工作条件最恶劣的零件,它受到气体压力,往复惯性力及侧压力的周期性冲击力的作用,它的工作温度高且不均匀,同时活塞的平均速度高又润滑不良。

根据活塞的工作条件,对其设计主要的要求是强度高,质量轻,导热性、抗磨性和缸内导向性好,同时还要保证机器运转时噪声小,易于制造,成本低。

2　活塞材料的选择及热处理由于活塞的工作条件恶劣,对于活塞材料,要求其具有高的机械性能,尤其是较高的高温强度,小的线膨胀系数,较高的导热系数,较小的密度以及良好的减摩性能与耐磨、耐蚀性能等。

495G汽油机活塞材料采用共晶硅铝合金,硅含量11%～13%,并夹有少量的Mg、Mn、Cu等元素,是汽油机活塞的常用材料,合金中硅元素能使线膨胀系数和密度下降,耐磨性、耐蚀性、硬度、刚度和疲劳强度提高,铸造流动性改善。

活塞毛坯用金属模铸造,以保证毛坯具有良好的铸造质量。

活塞毛坯需要进行热处理,以消除活塞铸件的内应力,增加热稳定性,增加强度和刚度,热处理后硬度HB=95～140,热稳定性可达0.025/100mm,抗拉强度要求大于200MPa。

3　活塞的结构特点495G汽油机活塞顶是平的,头部呈圆柱形,上面有两道气环槽和一道油环槽,裙部为椭圆形,并且上下呈正锥形。

活塞销孔的中心线偏向发动机的右侧,减少了活塞通过上止点换向时的敲击声,活塞销座与活塞头部采用了能增强活塞强度的连接结构。

活塞外表面镀锡,以改善活塞与缸壁的磨合性能。

485柴油机配气机构毕业设计说明书

485柴油机设计（配气机构）摘要本设计介绍了485柴油机配气机构的设计，主要是其各零部件的设计。

本次设计的485柴油机主要用于轻型载货车。

配气机构的功用就是实现换气过程，即根据发动机气缸的工作顺序，定时的开启和关闭进排气门，以保证气缸排出废气和吸进新鲜空气。

配气机构设计的好坏直接影响发动机整体的经济性和动力性，因此配气机构的设计在发动机整体设计上占有相当重要的作用。

在气门选择上，采用每缸两个气门的方案，其优点是比较简单、可靠，对于自然吸气式柴油机可以提高新鲜空气的进气量，降低气缸的热负荷，增加气缸的耐久性和使用寿命。

气门的驱动采用凸轮轴—挺柱—推杆—摇臂—气门机构。

凸轮轴布置形式是下置式，采用的是整体式凸轮轴，这样的凸轮轴结构简单，加工精度高，能有良好的互换性。

本次配气机构的设计，主要包括进、排气门的设计，气门弹簧的设计，以及凸轮轴的设计。

编写Matlab程序，计算得到挺柱升程表，绘出挺柱升程、速度、加速度曲线。

The 485 diesel engine in this design is mostly used in light truck.The function of valve timing mechanism is to realize the exchange process, namely according to engine cylinder working order, ensure that the intake and exhaust valves open and close at the proper time. The valve gear play a direct impact on the economy and power parameters of the engine, therefore, the design of gas distribution agency in the overall design of the engine play a rather important role. Arranging two-valve per cylinder, the advantages are that it is relatively simple, reliable, for the naturally aspirated diesel engines can improve the fresh air into the cylinder, reduce the heat load of the cylinder to increase the durability of the cylinder and use life. The driving mechanism of valves is camshaft, tappet, pushrod, rocker, valve train. Camshaft arrangement is under the form of home-style, using the integral camshaft, such camshafts have simple structure, high precision machining, and good interchangeability.This design, including exhaust valve, intake valve, valve spring, and camshaft. Write Matlab program, calculate tappet lift table, map the curves of tappet lift, speed and acceleration.KEY WORDS: Diesel engine, Valve timing mechanism, Camshaft, Valve目录前言 (1)第一章485柴油机的设计要求 (3)第二章485柴油机工作过程热计算 (6)§2.1485柴油机工作过程热计算已知参数 (6)§2.2485柴油机工作过程热计算 (6)§2.2.1 一般参数的计算 (6)§2.2.2 进排气过程计算 (7)§2.2.3 压缩终点参数计算 (8)§2.2.4 燃烧过程的计算 (8)§2.2.5 膨胀终点参数的计算 (8)§2.2.6 指示参数的计算 (9)§2.2.7 有效参数的计算 (9)第三章485柴油机主要性能参数的选择 (10)§3.1平均有效压力P (10)me§3.2活塞平均速度C (10)m§3.3行程缸径比DS/ (11)§3.4曲柄连杆比LR/ (12)§3.5气缸中心距 (13)第四章配气机构总体布置 (14)§4.1气门数目、布置和驱动 (14)§4.2凸轮轴的布置和传动 (14)第五章气门组的设计 (15)§5.1气门的设计 (15)§5.1.1 气门的工作条件与设计要求 (15)§5.1.2 气门的结构和设计 (16)§5.1.3 气门材料的选择 (19)§5.2气门导管的设计 (19)§5.3气门通路面积的校核 (20)第六章气门弹簧的设计 (23)§6.1气门弹簧概述 (23)§6.2气门弹簧尺寸的确定 (23)§6.3气门弹簧的校核 (28)§6.3.1 气门弹簧的强度校核 (28)§6.3.2 气门弹簧的共振校核 (29)第七章凸轮轴与气门传动件的设计 (31)§7.1凸轮轴的设计 (31)§7.1.1 凸轮轴的设计要求及结构 (31)§7.1.2 凸轮轴尺寸的设计 (31)§7.2挺柱的设计 (35)§7.3推杆和摇臂的设计 (36)结论 (37)参考文献 (38)附录 (39)前言柴油机的发展，已有一百多年的历史，通过这一长时间的不断改进和更新，已经发展到了比较完善的程度。
