Compared with the lathes that Du Zhongxiao remembers, the current lathes are extremely simple, and each one can only process one specification. In order to ensure accuracy, the turning tool cannot be adjusted, and the diameter of the processing is fixed. The shaft is clamped at one end and the top tip is used on the lathe. No matter how large the remaining amount is, it is just a knife. After processing, turn the processing parts and turn them again. A shaft of one specification, a rough car, a semi-finished car, a semi-finished car, requires three lathes. Several bearings of several specifications are used to process ball lathes, and half-finished car, and half-finished car is placed in half a room.

For machine tools, is the biggest thing to do is control and adjustment. Without that technical ability, there is no general machine tool here, all of which are used to process specific parts and specific specifications. With the abandonment of control and adjustment, the machine tool mechanism is extremely simplified and has a high name. In fact, it is a fixed and simple tooling, and operating the machine tool becomes a stamina.

All the machines manufactured here, including machine tools, all kinds of parts, shafts, holes, etc., only have a few specifications, and the accuracy is only one requirement. Often, a few specific machine tools are required for a part. If it is not an iron supervisor, it cannot afford the high cost.

Du Zhongxiao didn't want to do this, but there was no way. This is actually the least economical and inflexible method of using the assembly line special machines of later generations, which was produced in small batches. But if this is not the case, it is impossible to guarantee the accuracy at all, nor can it ensure the universality of parts.

A steam engine uses a machine tool lined up with several large houses, one by one, and it looks very spectacular. In a few months, the main job of these nearly a hundred people is to build these specialized machine tools, and sometimes people have to be transferred from the iron supervisor.

Du Zhongxiao looked over all the way and felt that these are all fixed assets. If the steam engine cannot be made, how much money will be wasted by these machines alone. Of course, once the machine model is determined, the speed of output explosion is also amazing.

There is no way to produce machines at such a large cost. The technology cannot be achieved, and it cannot be systematic. Of course, there are also benefits that others can’t imitate. Not to mention measuring and mapping according to machines, even if others can’t create drawings, where can you buy these machine tools? In this era, I want to make them by myself, not to mention individuals, and even the country has few people with such material and financial resources.

Relatively speaking, there are relatively fewer machine tools for planing and milling, and they are highly versatile, unlike shafts and holes. There are many lathes, grinders and boring machines, and several are arranged in groups and are piled up. Fortunately, the structures are similar, and manufacturing is not particularly difficult, but the specifications are different.

After walking through a long lathe team, there were some special parts, and now they are dedicated to making gears.

Gears are important parts in the machine industry and have a long history. Specifically in this era, cylindrical gears and bevel gears have become very common. Some can be mass-casted, and water wheels and water mills are used in large quantities. However, in terms of technical details, theory and processing are restored to the original shapes of triangular teeth, and basically all the tooth shapes are triangular teeth. For the iron monitoring machine industry, the original tooth shapes of triangular teeth have no longer met the technical requirements.

The mathematical knowledge of gears that meet the meshing requirements is not complicated, and the calculation of tooth shape does not exceed the knowledge range of the Iron Monitor Mathematics Booklet. Speaking of gears, Du Zhongxiao remembers the name of involute lines, and listing equations with algebraic knowledge is just that. Theoretical knowledge is not difficult, but actual processing is difficult. This kind of complex curve is very difficult to use machine tools, and design is a difficult problem.

With hundreds of machine tools over there, these people are making machines that can process series of gears. The same idea is that each type of princess uses a set of special machines, and each machine only completes one process. The machine is still being manufactured, and most of the parts are grinding by hand, which is very troublesome and the scrapping rate is high. Du Zhongxiao dared not calculate the cost with them at all. Anyway, a large amount of steel produced by the Iron Supervision Bureau is not able to sell, so they can go.

Gears are basically not used in steam engines. In history, Watt used planetary gears because the linkage mechanism was patented, so there is no trouble now. However, the general power machine for steam engines operating, driving other machines requires a lot of gears, and this step will eventually be taken.

After seeing the parts made and the various machines piled up by several large houses, Du Zhongxiao really didn't know what to say. There are so many machines, later generations, a huge factory, with machines roaring and thousands of products. But here is quiet, only a steam engine was built, and the technology is not mature. Almost all the things here are piled up with money. Of course, the sales channels of the Iron Supervision have not been built, and the products are backlogged, and it doesn't matter if the iron exchanges for money.

There was a booklet on the table at the end. It seemed that the people here valued it very much and specially made a cover with wooden boards. However, there were too many people turning it over and it was still covered with oil, so it was obvious that it was too late to wipe it.

Du Zhongxiao stepped forward and opened the booklet. He saw that every page was drawn with graphic and written with instructions next to it. After training, the pictures on the booklet were very detailed and were drawn according to three views and axonal measurements. Although this knowledge was taught by Du Zhongxiao, the level of drawings these people was much higher than that of Du Zhongxiao now, and it was very accurate. There is no way, if you don’t practice craftsmanship frequently, you will be able to get your hands on it.

The booklet is a collection of various mechanisms, from crank links, to gear cams, to ratchet chains, which are both proposed by Du Zhongxiao and summarized by them. The last half is white paper, which seems to be summarized in practice and will be added.

This is the basic skill of mechanical design. Only by mastering various mechanisms can you flexibly use it in machine design and complete various actions. This kind of work cannot be achieved by a clever idea, but by continuous learning and practice and active summary.

The value of this booklet is inestimable. Without so many outstanding talents, without such a machine, for them to learn and practice, and without such an atmosphere of unity and positive learning, it would be difficult to produce.

Tao Shiqi, who has been with Du Zhongxiao for several years, has been able to give many suggestions on improving the steam engine. These nearly 100 people were selected from the 10,000 or 20,000 trainees, and selected them from many states to train them. There are also those who are good at learning, and those who are particularly hands-on, help each other, learn from each other, and learn from each other's strengths and weaknesses to achieve this achievement. Du Zhongxiao spared no effort. No matter what their ideas were, they supported them at all costs. They had a prize when they were right, did not ask if they were wrong, summed up their experience and attracted lessons. After this special period, it would be difficult to find such a group of people to provide the same conditions.

After closing the booklet, Du Zhongxiao slowly walked back to the original room. Nearly a hundred people stood next to the steam engine that had already been running, looking at Du Zhongxiao with eager eyes. During this period, everyone was obsessed with researching technology and entering a state of forgetting things and forgetting each other, and didn't know what the boss saw.

Looking at everyone, Du Zhongxiao nodded: "Okay, okay, all are very good. You have done your best. I will order the cafeteria to add food tonight."

Everyone looked at Du Zhongxiao, and everyone was confused. What does good mean? There are so many machines, which one has its strengths, which one is insufficient, and how to improve it. Without mentioning a word, everyone is confused.

How did Du Zhongxiao mention it? What he used to do was simple. He could tell the advantages and disadvantages with his own experience and knowledge at a glance. Now he is so complicated that he can tell at a glance. He has no energy to study every machine carefully, and of course he has no specific opinions. If you don’t know the details, you think you are wrong, maybe they are right. If you mess up their ideas, you will have to take technical detours.

When starting, one person can push a car. But when the vehicle is driven, if you want to rely on manpower to drive the vehicle, it will be a mantis arm to block the car. This is the case with the Iron Supervision. Now it is running, and it is time for Du Zhongxiao to give instructions on specific issues.

Looking at the running steam engine, it runs smoothly, and just listening to the sound is much more pleasant than the original one.

After looking at it for a while, Du Zhongxiao pointed to the huge flywheel and said to Su Song: "If this machine is to do better, you have to take these people to do it. The important thing now is how to use the machine. Look, the flywheel over there is a fast rotation. Today's use is to choose a suitable belt that can use that wheel to drive other machines. Connect it to the forging hammer, it can replace hydraulic power. Connect it to the conveying material, it can replace human power. If you have spare energy, let these people make typhoon fans, you can use human power to blow the wind."

Su Song nodded: "If there is a belt connected, the large wheel has a small wheel, and the small wheel reaches the large wheel, it will be fast and slow, which is extremely convenient."

"Yes, that's it. But you have to choose this belt carefully and must be strong and durable. Never want to use silk and satin, just choose those that are particularly strong, such as various hemp, and can be weaved in many kinds. Try everything and choose the best one."

As a general power, the steam engine mainly relies on the flywheel to output power and belt transmission. For example, a train can directly drive the shaft, and of course, gears, chains, etc. can also be used, but compared with belts, the scope of application is much narrower.

Du Zhongxiao could remember what material is made of the belt? Anyway, there should be many other materials besides rubber. They can try the specific materials that are suitable. Just provide manpower and material resources and provide money to support it.
