Beasts Are Boundless

Chapter 143 Bearings And Steel Balls

Twenty days, for the long and cold winter of 18 months, is almost a matter of a snap of a finger.

However, the passage of time will not speed up because people look forward to the arrival of spring.

Time will pass little by little.

In the past two days, Ye Qiong called Tang Ying out of the caravan, and went to the laboratory to accompany him to fiddle with the steam engine, while studying the development plan of the tribe after the spring.

Ye Qiong is very clear about the principle of the steam engine. In the past two months, Ye Qiong asked Yang Dingtian to collect some scraps of copper and iron from the tribe. After Ye Qiong melted it, he planned to make a small one in the next few days. The steam engine comes out.

A steam engine, as its name implies, is to convert the energy of steam into mechanical energy. Its evolutionary products are an internal combustion engine and a steam turbine. Ye Qiong knows that the latter two things should not be thought about in a short time, but a steam engine can be made as long as you work hard. Out.

The broken copper and rotten iron that Yang Dingtian brought over were melted into liquid, and then poured into a mold that Ye Qiong had already made, which is a semi-closed boiler, and a piston would be added to it in the later stage. , and then form a fully enclosed space.

The working method of the steam engine is actually very easy to understand. In simple terms, it is to add water to the boiler, and then the pressure of the expanded water vapor will increase in the enclosed space, resulting in a device that can push the piston to start moving. force.

After the piston moves to a certain position, the steam will be discharged, and the piston that has lost pressure will return to its original position under the action of gravity.

Then the steam continues to superimpose, increasing the pressure, the piston rises, exhausts, and the piston returns to its original position, so a cyclic action is created.

After converting this up-and-down motion into axial motion through bearings and gears, and installing wheels on the outside, an original steam car was created.

Although it sounds very simple, in reality, it is more troublesome to make, such as the design of bearings and gears, the interaction of torque, and the plastic materials and lubricants that wrap the piston...

These problems had to be solved by Ye Qiong one by one before he could get the most primitive steam engine out.

However, as long as the core thing of the steam engine can be obtained, cars and trains will be just around the corner.

"Is this kind of thing really as magical as you said? Traveling thousands of miles a day..." Tang Ying asked Ye Qiong, who was pouring molten iron into the mold.

Ye Qiong nodded: "When will we build the maglev train, it can travel thousands of miles a day!"

Even though he said that, Ye Qiong didn't brag. After all, the maglev train's speed was nearly 600 yards per hour, and running 10,000 kilometers a day was like a game without stopping.

The average high-speed rail can reach 300 yards per hour.

"Wow~ Wouldn't it be possible to circle around the Dinglong Mountains in one day? It's amazing, then come on, get it out early, I really want to experience it!" Tang Ying said sincerely.

However, after Ye Qiong finished listening, he could only wipe the cold sweat from his forehead, then he looked up at the blue mother star above his head and said, "Let's live... If everything goes well, let alone the Dinglong Mountains, I'll take you there. Look up there."

After pouring the molten iron into the mold, Ye Qiong put the special iron pot in his hand on the ground, then started to scoop out the water from the wooden barrel with a ladle, and then poured it on the mold.

"Zi..."

The high temperature instantly turned the splashed water into steam and released it. Ye Qiong continued to scoop the water until the iron pot that had been formed in the mold was completely cooled down.

After directly breaking the mold made of clay, the boiler with a height of about one meter appeared in front of Ye Qiong and Tang Ying.

The task of the first step is completed. This one-meter-high iron furnace consumes a lot of iron tools in the tribe. Although it seems to be only one meter high, if it is handed over to Kuang Baichi, you can build a dozen of them at will. The long sword came out. Next is the piston. Ye Qiong did not make the piston iron. After all, the steam engine has not been officially put into use. The wooden piston is enough, so the remaining molten iron was poured into gears.

As for bearings...

Ye Qiong had to prepare for this century's problem, but there were people in the tribe who were more suitable for this.

Ye Qiong has made the gears, which are a bit larger, and there is no precision at all, and they will need to be further polished later.

To polish this arduous and time-consuming task, Ye Qiong did not intend to do it by himself.

After the gears cooled down, Ye Qiong hugged the gears, then took Tang Ying's little hand and walked towards the tribal blacksmith shop.

He handed over the gear to Luo Niu and another apprentice of Kuang Baichi, and then Ye Qiong showed Kuang Baichi something he needed urgently.

Steel balls!

A thing that must be hard enough and wear-resistant enough, Ye Qiong described it like this, and then described the size of the steel ball, the diameter should be as consistent as possible, and the error should be within millimeters.

The steel balls that must be used for spherical bearings are actually not difficult to make, but whether they are used well or not is another matter, and how well they are used directly affects the conversion rate of energy.

Ye Qiong doesn't have any requirements on the conversion rate now, just get one for him first.

Bearings are also a relatively easy-to-understand thing. In layman's terms, a medium is added between two objects to reduce the friction between them.

For example, if you want to move a boulder to another place, you can put some wooden sticks under the boulder, which is a plane bearing.

And between two circular objects, steel balls can also be added. The large ring wraps the small ring, and the steel ball is added in the middle. This is the bearing that must be used in making a car. This is a spherical bearing.

In addition to this, there are a variety of bearings, and some precision bearings are required, even at the nanometer level.

However, in terms of Xue Xing's technology level at present, Ye Qiong can't use those. When he needs to use it in the future, he can just find someone to research and develop it.

Now what Ye Qiong has to do is to start, as long as he can get the steam engine out, it will open the first door to the evolution of civilization.

Kuang Baichi listened to Ye Qiong's description. Although he was a little puzzled, he still heard the hardness and stiffness, and then subconsciously looked at a shelf in the inner room.

On the shelf, there were five black jars, which Ye Qiong asked Kuang Baichi to leave for him to build the longbow body.

Ye Qiong followed Kuang Baichi's gaze, and his face turned green. He wanted to test the water with his King Bone Crystal.

If it could be exchanged, Ye Qiong would rather Kuang Baichi melted the long sword that cut iron like mud...

After thinking about it, a few steel balls should not be used much. Now the steam engine is still very important, and it can only hurt a little.
