Lamina stirling engine model 翻译 ：15769767热声斯特林引擎模型I found the plans for this engine on the internet.我在互联网发现这种 引擎的制作方案 It's a Lamina flow engine based on the sterling cycle from what I have read.据我所知这是基于斯特林循环的斯特林发动机I honestly do not really know how this engine works but it runs on a external flame.老实说，我真的不知道这个引擎如何依靠外部火焰运行 It's a really simple engine to build .这是一个非常简单的引擎 This is a basic plan for the engine.这是引擎的基本方案 Copyright © 2008-2010 Mike Freeman 版权所有© 2008-2010 迈克弗里曼 Building the Engine 如何制造这款引擎 These are the 4 main parts of the engine:引擎的四个主要部分： 1。

The piston & cylinder 活塞与气缸 2 Regenerator Tube 蓄热管 3 Flywheel 飞轮 4 Flame 火焰 I used a small lathe & mill to make all the parts for this engine.我 用了一个小型车床和轧机，制作这种发动机的所有部件 A 4 jaw chuck is also useful if available. 如果有一个四爪卡盘也是很有用的 1.Piston & Cylinder 活塞与气缸 The piston is made out of graphite.活塞是用石墨制成的 It's the same material that is in a pencil.就是制作铅笔芯的材料 It gets all over your hands and is a mess to machine.它得到了所有你的手和机器是一团糟It is about 0.625 inch diameter and 0.500 inch long.它的直径约为 0.625 英寸长度为 0.500 英寸。

Graphite works exceptionally well in these sterling hot air type engines.石墨非常合适做斯特林热机的活塞 The connecting rod is just a piece of 0.125 inch aluminum I cut with a band saw.连杆只是一块从锯条上切下的 0.125 英寸铝条 I used a small finish nail as a wrist pin.用一个小钉子做插销 It is about 0.090 diameter and is very sloppy (my fault).它的直径约是 0.090 英寸（粗略估计） There is a small hole in the side of the piston where the pin is inserted.将销子插入石墨活塞一端的小孔中固定连杆 The cylinder is made of brass.气缸是用黄铜制成的 I had some laying around and used it for this project.我用车床加工这个气缸。

The cylinder bore has to be machined to a high precision.气缸应精密加工 It has to be only a few ten thousands over the piston size.内径只能比 活塞大在百分之一以内 The cylinder must have a high mirror like polish.气缸内壁必须抛光的像一面镜子 I made the cylinder first and then made the piston to fit.我先做好气缸，然后再做合适的活塞 If it does not fit, the engine will not even run.如果气缸和活塞尺寸不合适， 甚至会导致发动机不能运行 I had this problem when I tried to use a test tube as a cylinder. 我用一支试管做气缸时，就遇到了这个问题 The glass was out of round a few thousandths which made it impossible to get the engine to run.玻璃试管的内径不匹配会导致发动机不能运行。

Regenerator Tube 蓄热管 The regenerator tube is just a regular pyrex test tube I bought off Ebay.这个蓄热管只是我从易趣网买的一个普通的耐热试管 The tube needs to be filled with coarse steel wool.试管内用粗钢丝棉填充 Size 18mm x 150mm long.试管尺寸为 18 毫米（直径）x 150 毫米（长度） I tried cutting one shorter and the engine did not run.我切了一支短的试管，引 擎就不能运行 I needed the full length tube.需要全长管 You can cut these tubes with a diamond wheel and a dremel if you have to.你可以用 钻石砂轮切割这些管子 The diamond wheels are cheap and only cost a few dollars.钻石轮很便宜，只需几美元。

To hold the test tube to the cylinder, I used a method I saw several guys use on the YouTube videos.我用在 youtube 视频上看到过的方法将试管 固定在气缸上 I counter bored the cylinder about .250“ deep to slip fit over the pyrex tube. 在气缸中钻一个大约 0.250 英寸深度的孔来安装耐 热试管I made a washer out of aluminum and tapped some 4-40 screws in the cylinder to hold the washer on.我在气缸上攻出了 4—40 螺纹来固 定铝制垫片In between the cylinder and the washer is a rubber O-Ring that just fits over the tube.在气缸和铝制垫片之间有一个刚大过试管的 o 形橡胶圈 As you tighten the screws, the rubber gets squashed and tightens on the pyrex tube to hold it.当你旋紧螺丝，就会挤压橡胶圈从而将耐热试管 固定在气缸上。

This keeps the tube from cracking.当心试管破裂 I already cracked three tubes trying to hold it with a split clamp type of holder.为了固定好试管，我已经弄破三支试管了My engine needed a restrictor to separate the cylinder from the regenerator tube.这种引擎需要一个节流圈将活塞和蓄热管隔离开来 This restrictor seems to be a bit of a mystery because some engines do not seem to need one.这节流圈似乎是一个谜，因为某些引擎似乎并不需要它 The hole size is critical and ended up being 0.170 inch diameter on my setup.节流圈孔的大小是至关重要的，我制作的引擎中用的直径是 0.170 英 寸 It is made of brass and has a rubber O-ring over it to keep it somewhat tight in there.节流圈由黄铜制成并且套一个橡胶圈在上面以固定 位置。

I let the piston push it in there so that there is no space between the piston and this brass restrictor.我让活塞把节流圈推进试管， 以便活塞和黄铜节流圈的之间没有空隙 As you can see, I ended up making different sized restrictors until I found one that worked well.我制作尝试了各种不同大小的节流圈，直到我发 现效果最好的那个 If it's too big or too small, the engine is completely lifeless.如果节流圈过大或者过小，发动机的动力就没那么强劲 了 The Flywheel 飞轮 The flywheel is made out of scrap cold roll steel.飞轮是用废 冷轧钢制成的 It's just a round wheel with a hole in it.只 是一个有孔的圆轮The shaft is made of aluminum and I have two small bearings in the square pedestal to support the wheel & shaft.方形底座上有两个小轴承来固定铝制的轴和飞轮。

I thought about using brass bushings but the engine is very weak and needs bearings wherever I can fit them.我曾想用黄铜轴套，但引擎是动力不强，需要轴承I tapped the shaft 4-40 and used a socket cap screw to hold the flywheel tight to the bearings.我在轴上攻了 4—40 螺纹，用螺栓将飞轮固 定在轴承上 It works well.运作良好 The Flame 热源 For the flame I just made an alcohol burner out of a baby food jar.我 利用婴儿食品瓶做了一盏酒精灯 I bought wick from the hardware store. 我从五金店买了灯芯 It's cr。
