连杆销

In the first, the length of every poleof the leading four-bar mechanism are determined bypainting,secondly, the base of mechanic model ofsupport-surrounding, the mechanism and loads on the support isdecided. The next work, with the condition of the design, the mainmechanics of hydraulic support is analyzed and calculated by planeand spatial model. Finally, the under frame, top beam cave shield,wrists and hydraulic column are analyzed by calculation. And drawout all the process drawings.

首先，通过作图确定支架的四连杆机构各杆系的长度；然后，以力学模型为依据，分析了液压支架的顶梁、掩护梁上载荷的作用机理，得到了较为合理的支架载荷的计算公式；其次，结合设计的支架，从平面和空间两方面对支架主要结构件进行受力分析；最后对支架主要结构件、连接销轴进行强度效核，并画出所有的机械图。

Refinishing cylinders requires 12 to 20 hours (according to the type of engine). This includes fitting and installing new pistons, rings, piston pins, and connection rods.

整修气缸需要12～20小时(时间长短取决于发动机的类型)，这包括调配和安装新活塞、活塞环、活塞销和连杆。

The dog-leg cam, figure plate and slide block are used to realize radial multiple core pulling on the mould, and that gear-rack mechanism or connecting bar mechanism is not adopted, so that the die casting mould is simplified.

该模具利用异形弯销、转盘及滑块完成多型芯径向抽芯，而未采用一般的齿轮一齿条机构或连杆机构，简化了模具结构。

Because of the connecting rod is one of dyadic engine of piston and main compression engine part, whose larger end hole and crank shaft link up , the small head hole links up by the wrist pin and the piston , whose effect is that the piston gas pressure is transmitted to the crank shaft , collect crank shaft gas in driving but setting a piston in motion to compress a cylinder.

因为连杆是活塞式发动机和压缩机的主要零件之一，其大头孔与曲轴连接，小头孔通过活塞销与活塞连接，其作用是将活塞的气体压力传送给曲轴，又收曲轴驱动而带动活塞压缩汽缸中的气体。

Cylinder wall and piston are lubricated by the engine oil sprayed out of the engine oil cooling spraying hook located on auxiliary oil passage of cylinder block; piston pin is lubricated by the lubricant collected in the hole drilled on top of connecting rod small end.

气缸壁和活塞通过位于气缸体副油道上的机油冷却喷钩喷油润滑，活塞销由连杆小头顶部钻孔集油润滑。

In diesel engine cylinder, the piston part of the cycle in the compressed gases, and in another part of the work cycle of the combustion gas mixture within the cylinder so the piston top surface expansion high pressure (about 116 ~ 120Kgf/cm2)°under high temperature (about 569°C) gas role, and the pressure through the piston pin, connecting rod to the crankshaft.

在柴油机气缸内，活塞在一部分工作循环压缩气体，而在另一部分工作循环气缸内混合气体燃烧膨胀使活塞顶面承受高温（约569°C）高压（约116～120Kgf/cm2）气体的作用，并把压力通过活塞销、连杆传给曲轴。

The frequency characteristics of instant- taneous signal of main abnormalities in diesesl engines,including valve sound, piston pin sound,connecting rod bearing sound and sound from the main bearing of crankshaft are analyzed.

从使用角度出发，采用频域分析法，分析了柴油机中气门、活塞销、连杆轴承、曲轴主轴承等部位主要异响的瞬态信号频率特征。

In "I have no people, who have my spirit" of the work of the numerous ideas for bearings and piston rings, piston pin, the valve seat, connecting rod, disc, simultaneously, friction film, magnetic materials, and other industries to provide large quantities of high Accuracy, precision double-face grinder.

本着&人无我有，人有我精&的工作思路为全国众多轴承和活塞环、活塞销、气门座、连杆、阀板、同步器、摩擦片、磁性材料等行业提供大批量高精度、精密双端面磨床。

Products mainly for the automotive operating steering rod ball head, suspension arm ball head, before and after the stability ball head rod and other automotive parts such as ball connections.

经营产品主要为汽车转向系拉杆球头、悬挂摆臂球头、前后稳定连杆球头及其他汽车球销连接件等。

Second, oil does not come into contact with the compressed gas external drive mechanism, such as in reciprocating compressor crankcase parts, crank pin, crank bearings, connecting rod slide, slide, crosshead; and speed rotary compressor bearings , gear and other growth.

其二为油不与压缩气体接触的外部传动机构，如往复式压缩机曲轴箱中零件、曲柄销、曲柄轴承、连杆滑块、滑道、十字头；回转式和速度式压缩机的轴承、增速齿轮等。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
