活塞销

At this time, the caulking portions (26) are formed at upper and lower ends of an interference preventive portion (24) defined within the connecting chamber (22) and cause the upper and lower ends of the piston pin (30) to be fastened to the piston (20) within the connecting chamber (22) of the piston.

这时，箍紧部分(26)形成在连接室(22)中干涉预防部分(24)的上端和下端，并使得活塞销(30)的上端和下端在活塞连接室(22)中被固定到活塞(20)。

According to the present invention, there is an advantage in that an outer diameter of the piston (20) is not changed during its assembling process, since the piston pin (30) can be fastened to the piston (20) merely by causing only the caulking portions (26) of the piston (20) to be subjected to the plastic deformation.

根据本发明，有一个优点就是，既然活塞销(30)仅仅通过活塞(20)的箍紧部分(26)的塑性变形就能够被固定在活塞(20)上，因此活塞(20)的外径在其装配过程中不会变化。

These dies are made from cast iron with steel inserts for the gudgeon pin holes and the cores.

这些模具组成部分应用了铸铁材质，而中空和活塞销孔部分的抽芯应用了钢材质，这些抽芯可以保证活塞销和内孔部分的部位形状。

Is a professional company specialized in piston pin for automobile engine.

杭州万马活塞销有限公司是活塞销的专业生产厂家。

The piston end of the rod is attached to the piston by the piston pin, or wrist pin

连杆的活塞端用活塞销或销轴安装在活塞上。

The piston pin fits through one side of the piston, through the small end of the rod, and then through the other side of the piston.

活塞销贯穿活塞，把连杆小头与活塞连在一起，并将连杆保持在活塞中心的适当位置处。

The piston mathematical model of some type engines in topology optimization was founded using variable density method. According to the optimization area of the piston pin seat and the thrust face, the topology optimization of piston structure in this area was studied using the HyperWorks software premising the stability of skirt's distortion.

建立了某高速发动机活塞的变密度法拓扑优化数学模型，以活塞销座和推力面之间的区域为优化区域，在保证裙部变形稳定性的前提下，利用HyperWorks软件对该区域的活塞结构进行了拓扑优化。

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 gap between piston and cylinder wall of an internal combustion engine is small, however it may induce the piston secondary motion periodically and generate unwanted sound and vibration.

由于活塞缸套之间存在间隙，活塞在缸套内会产生横向及绕活塞销旋转运动，称之为活塞二阶运动。
