industrial lord

Chapter 177 Part by Part Research

This is Benz's land, so everyone asked him to talk first.

"Master," Benz said, "I think we can try to make a smaller one first, and install it on a cart. Maybe it can replace a horse to pull a cart."

Frederick nodded and said: "This idea is very good. If you want it to replace a horse-drawn carriage, it needs to have a higher load and speed than a horse-drawn carriage, and lower driving costs than a horse-drawn carriage."

Benz shook his head and said, "That's not what I mean. I'm talking about your carriage, my lord. If you can use a steam engine instead of a horse, how can other nobles compare to you."

Frederick understood that he wasn't talking about steam trucks, but luxury cars that looked like nobles.

"Put my car aside first." Frederick shook his head, "First study the tractors used for farming."

Benz thought that he had flattered the horse's hoof this time, and immediately said: "This machine can be directly modified with the chassis of a steel-framed carriage. The main thing to be modified is the steering part of the front wheels, and the bearings also need to be strengthened." .”

"Especially the bearings. During the six-day defense battle, more than half of the damaged carriages were due to faulty bearings. Later, during maintenance, many bearings were found to be severely worn."

Frederick recorded the problems he said in his notebook, especially the bearing problem, and drew a ★ key mark in front.

He had heard about bearings before, and the factors that caused the problem ranged from materials, design, machining accuracy to lubricants.

Now the bearing factory is in charge of a student of Ogilvy, and Frederick raised his head and said to him: "Schaeffler, the environment in which bearings will be used in the future will be much worse than before, so the design, materials and processing must be raised, and alloys should be used. Just use alloys, use magic to strengthen metals, first satisfy the performance and then control the cost."

After Schaeffler nodded, Frederick said: "I repeat, a machine is composed of many parts, and the performance of the machine is the sum of the performance of each part. If the performance of a certain part is insufficient, it will drag down the whole machine. "

Frederick told them a lot of similar things, and today's repetition of the old saying is to make everyone tighten the string again.

The tractor he plans to study this time refers to the "Creation" 1958-horsepower steam tractor produced in Shenyang in his hometown in 18 in terms of power. , there are still many problems to be solved.

Katharina recorded this passage, feeling very surprised at the same time. At first, she thought that today's meeting would be chaired by Benz or the already prestigious Schmidt, but unexpectedly it was Duke Wesson.

Ben finally said: "The previous carriage used elastic wooden boards and slime film layers of shock absorbers, and later steel carriages and slime glue were used on steel carriages. The result is slime. Mu glue was squeezed out after a long distance with the load, some people simply did not use that glue and only used steel bars, and finally found that the effect was not much worse. "

"I think that in the future, slime glue will not be used between the axle and the chassis to absorb shocks. All of them will be made of steel. The smelter will develop some more elastic steel, like the crossbow arm of the steel crossbow. The car dampens."

Frederick nodded and said, "Alfred is not free to come here today. I will discuss this matter with the smelter later."

"I have a suggestion, you can study the spring shock absorber."

The development of technology is like the shock absorption of a carriage. In the beginning, rattan or flax was woven into an elastic net to make the bottom of the carriage, and the carriage floor and chairs were placed on it. New materials such as elastic slime glue After coming out, a layer of wooden boards and a layer of glue are used to separate the axle from the carriage, and then partial modifications are made according to the requirements. If it is found that it does not meet the requirements, the material or design is changed, and another modification is made until new requirements appear.

After confirming that Benz had finished speaking, Frederick motioned for Schmidt to speak.

Schmidt opened the notebook and took out a folded drawing and handed it to Frederick, and said at the same time: "Now we are researching the double-cylinder steam engine, and at the same time we plan to recover the steam and use it to heat and replenish water, reducing the water carried by the boiler. , to reduce the fluctuations caused by boiler water replenishment.”

Frederick was a little surprised when he opened the drawing. He naturally understood steam recovery, but this technology is mainly used on ships to save precious fresh water. On land, it is only used by high-horsepower steam engines and steam turbines that consume large amounts of water.

But he doesn't care about it, as long as it doesn't explode, let them study it. If it succeeds, it can save water and reduce the weight of the boiler, which can be used in future steamships. As for starting from scratch.

The same is true for the double cylinder, let them try it, it is a good thing, and it will provide experience for the next locomotive.

After reading the drawings, Frederick asked him, "How do you plan to process the crankshaft?"

Schmidt replied: "I plan to process it into several parts separately, and finally assemble and weld them together."

Frederick nodded. In this case, the fitted crankshaft should be sufficient. Let’s try it first, but he still reminded: "This kind of fitted crankshaft can only be used at low speeds."

Schmidt expressed his understanding, and then asked a question: "Principal, are the wheels of this tractor driven by this special chain? Will it be too heavy?"

"And its processing is also very complicated, and it needs to be assembled bit by bit."

The tractor designed by Friedrich used a combination of open chain drive and gear drive instead of the belt ratio drive commonly used when steam engines drive other machines.

The reason why he adopted the chain drive was that steam tractors in the 19th century did the same, and the efficiency was higher than that of the belt. He also planned to use this opportunity to point out the chain and then sell bicycles and tricycles.

Just like the factory building in the industrial park adopts a reinforced concrete frame structure instead of a mature and usable full-brick structure, technological development can take a bigger step if necessary, and at the same time cultivate corresponding skilled workers.

Compared with the small-scale use of new technologies, the foundation of new technology promotion - the cultivation of technical personnel is the most difficult, otherwise, where will people build cathedrals and large libraries in the future.

The same is true for the chain this time. The roller chain is used in many occasions, and the various technologies of the bicycle are inferior to it.

After listening to Friedrich's explanation of the importance of researching roller chains, Schmidt pondered and said: "To produce this kind of chain, we need to improve the punching machine, design new machines, and add heat treatment equipment, which is enough to build a factory. There's a new factory."

Frederick said indifferently: "In addition to the chain and the matching gear plate, the market for this system will be huge in the future."

"If anyone chooses to specialize in this business, then go to the bank to apply for a loan. When you get the machine out, maybe you can catch up with the completion of the new industrial park."

The eyes of many students present brightened, and another way to get rich appeared.

Frederick didn't care who won the chain factory in the end, anyway, as long as he had the chain to use, this item was over, and then said: "If this tractor is only used to cultivate the land, the clutch will not be used if the shaft is reversed and reversed. , It is enough to control the gas outlet of the boiler, but when the customer buys it back, it will be used to drive the mill, sawing machine or other equipment, so a clutch needs to be installed at the end of the transmission chain to prevent it from running when the flywheel is working.”

"For this reason, I designed a clutch with forward, idling and reverse gears, and you can see if it works."

Below the clutch he designed are two driving gears that mesh with each other. These two gears are relatively wide and arranged in a "" arrangement. Half of them mesh with each other, and the other half is free to drive the driving gear.One of the drive gears is connected to the crankshaft of the steam engine and drives the other, and their rotation directions are "opposite" at this time.

The upper driven gear is arranged in the shape of "╪╪". It is composed of two left and right gears and a sleeve as a whole, which is sleeved on the shaft and can move left and right on the shaft.When it moves to the left, the driven gear on the right meshes with the driving gear on the right. At this time, the shaft rotates forward. When it moves to the right, the meshing shaft of the left gear rotates reversely. When it moves to the middle, the two driven gears are not connected to the driving gear. The gears mesh, so they don't turn.

Everyone chattered and discussed, and someone said: "This clutch is good, the driven gear and the output shaft need to be splined, but the speed should not be too high when adjusting, it is best to stop."

Frederick nodded, and had a preliminary exchange of ideas on how to control the movement of the driven gear.

Then he looked at Katharina and said with a smile: "Your task is very heavy, and it is a long-term job."

Catherine said nervously: "Your Excellency, I will definitely be able to do it well!"

Frederick laughed twice, and said, "Don't be nervous, you are also a lecturer at Weissburg University now, and those guys are still students, and they have to call you teacher when they see you, and you call me principal just like them alright."

Katharina nodded, and then said: "I can understand the principal's request to improve the efficiency of magic elements. My father and I have done some research in this area and can help."

Frederick shook his head and said, "It's not helping me. This machine will also calculate technology shares when calculating profits in the future. The heating system of the boiler accounts for a large proportion, so you are also doing research to make money for yourself."

"Ah?" Katharina was startled, "Are you telling me that I can earn money from this machine besides my salary?"

Frederick pointed to Schmidt and the others, and said, "Just ask them. Don't look at their plain clothes in front of me now. When they go out to play, who doesn't have a gold chain around their necks?"

Katharina opened her mouth. She is a lady from an old aristocratic family. She pays attention to low-key luxury and connotation. She didn't know how to complain for a while.

Anyway, Frederick was too lazy to complain about these guys, and continued to say to Katharina: "We are not as good as you in this aspect of magic principles, but they are more familiar with materials than you, so we can communicate with them more."

Katharina nodded. It is well known that Wessen State produces elemental metals.

Frederick discussed with her the idea of ​​improving efficiency, and then talked about the steering system.

The steering system is very simple. A turntable drives an iron chain. One end of the iron chain is connected to the two ends of the front wheel axle. When the steering wheel turns, the turntable is driven, and then the iron chain pulls one front wheel backward, and the front wheel turns to that side.

However, the details need to be studied slowly. Today everyone had a preliminary breath, and the next day began to gradually study in depth.
