This is Benz's territory, so everyone let him speak first.
"Sir," Benz said, "I think we can try to make a smaller one first and install it on the cart. Maybe it can replace the horse to pull the cart."
Frederick nodded and said: "This is a good idea. If you want it to replace the horse-drawn carriage, the load and speed of the car must be higher than that of the horse-drawn carriage, and the traveling cost must be lower than that of the horse-drawn carriage."
Benz shook his head and said: "That's not what I meant. I was talking about your carriage, sir. If you can use a steam engine to replace the horses, how can other nobles compare with you?"
Frederick understood that he was not talking about steam trucks, but luxury cars that were the face of nobles.
"Put my car aside for now." Frederick shook his head, "Let's study the tractor for farming first."
Benz thought that he had flattered the horse's hooves this time, and immediately said: "This kind of machine can be directly modified with the chassis of a steel frame truck. The main thing that needs to be modified is the steering part of the front wheel, and the bearings also need to be strengthened.
.”
"Especially the bearings. During the Six-Day Defense War, more than half of the damaged carriages were due to problems with the bearings. Later, during maintenance, it was found that many bearings were seriously worn."
Frederick recorded the problems he mentioned in his notebook, especially the problem of bearings, and put a ★ key mark in front of it.
He had heard about the bearings before, and the factors leading to the problems ranged from materials, design, machining accuracy to lubricating oil.
Now the bearing factory is in charge of a student from Ogilvy. Frederick raised his head and said to him: "Scheffler, the use environment of bearings will be much worse than before, so the design, materials and processing must be improved. Alloys should be used."
Just use alloys, use magic to strengthen metals, satisfy the performance first and then control costs."
After Schaeffler nodded, Frederick said: "I emphasize again that a machine is composed of many parts. Machine performance is the sum of the performance of each component. Insufficient performance of a certain component will drag down the entire machine.
"
Frederick often told them similar things. Today, the old words are mentioned again to ask everyone to tighten the string again.
The tractor he plans to study this time is based on the 18-horsepower "Chuangjue" steam tractor produced in Shenyang in his hometown in 1958 in terms of power, and the structure is based on the common steam tractors in Europe and the United States in the 19th century, even if it uses the "I Xunsi" technology
, there are still many problems to be solved.
Katharina recorded this conversation and felt very surprised at the same time. At first, she thought that today's meeting would be hosted by Benz or the already famous Schmidt, but she didn't expect that it would be Duke Wesson.
Ben finally said: "Previously, the carriages used elastic wooden boards and slime film layered shock-absorbing strips. Later, the steel frame carriages used steel bars and slime glue. The result was Slime
The glue was squeezed out after carrying the load for a long distance, so some people just didn't use the glue and just used steel bars, and finally found that the effect was not much different."
"I think that in the future, slime glue will no longer be used between the axle and the chassis for shock absorption. All will be made of steel. The smelter will develop some more elastic steel, like the crossbow arm of the steel crossbow, to
The car is damped."
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 research spring shock absorption."
The development of technology is like the shock absorption of carriages. At first, rattan or linen were 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 it came out, a layer of wood and a layer of glue were used to separate the axle from the carriage. Then, local modifications were made according to the needs. If the requirements were not met, the materials or designs were changed, until new requirements emerged and another modification was made.
After making sure that Benz had finished speaking, Frederick motioned for Schmidt to speak.
Schmidt opened his notebook and took out a folded drawing and handed it to Frederick, and said at the same time: "Now we are studying a two-cylinder steam engine, and we plan to recover the steam and use it to heat and replenish water, so as to reduce the water carried by the boiler.
, to reduce fluctuations caused when the boiler is replenished with water.”
Frederick was a little surprised when he opened the drawing. He naturally understood steam recovery, but this technology was mainly used on ships to save precious fresh water. On land, it was only used by large water consumers such as high-horsepower steam engines and steam turbines.
But he doesn't care about it. As long as it doesn't explode, let them study it. If it works, it can fill less water and reduce the weight of the boiler, which will also be used in future steam ships. If it doesn't work, let it go for now. It won't be used when building steam ships in the future.
As for starting from scratch.
The same goes for twin cylinders. Let them try it. It will be a good thing and provide experience for the next locomotives.
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 nested crankshaft should be enough. Let's try it first, but he still reminded: "This kind of nested crankshaft can only be used at low speeds."
Schmidt understood, and then asked a question: "Principal, do the wheels of this tractor need to be driven by this special chain? Will it be too heavy?"
"And its processing is also very complicated, and it needs to be assembled piece by piece."
The tractor designed by Frederick used a combination of open chain drive and gear drive, rather than the belt ratio drive commonly used today when steam engines drive other machines.
The reason why he uses chain drive is that steam tractors in the 19th century also did this and it is more efficient than belts. He also plans to take this opportunity to introduce the chain and sell bicycles and tricycles.
Just like the factory building in the industrial park uses a reinforced concrete frame structure instead of a mature and usable all-brick structure, technological development can take a larger step if necessary, and at the same time cultivate corresponding skilled workers.
Compared with the small-scale use of new technologies, the basis for the promotion of new technologies - the training of technical personnel is the most difficult, otherwise there will be no people to build cathedrals and large libraries in the future.
The same goes for the chain this time. The roller chain is used in many applications, and it is inferior to various bicycle technologies. How long will it take if we don't get it together at this time?
After listening to Frederick explain the importance of studying roller chains, Schmidt thought thoughtfully and said: "To produce this kind of chain, we need to improve the punch press, design new machines, and add heat treatment equipment, which is enough to build a factory."
It’s a new factory.”
Frederick said nonchalantly: "In addition to the chain and the matching gear plate, this system will have a big market in the future."
"If anyone chooses to specialize in this industry, then go to the bank and apply for a loan. When you get the machine out, maybe you can catch up with the completion of the new industrial park."
Many students here's eyes lit up, and another way to make a fortune appeared.
Frederick didn't care who took over the chain factory in the end, as long as he had a chain to use, this was enough. Then he said: "If this tractor is only used for plowing, and it reverses the rotation of the shaft, it does not need a clutch.
, it’s enough to control the boiler’s gas output, but when the customer buys it, it will be used to drive a grinder, sawing machine or other equipment, so a clutch needs to be installed at the end of the transmission chain to prevent the flywheel from running when it is working.”
"For this purpose, I designed a clutch with three gears: forward, idle and reverse. Let's see if it works."
Below the clutch he designed are two intermeshing drive gears. The two gears are relatively wide and arranged in a "" shape. Half of them mesh with each other and the other half is free to drive the drive gear. One of the drive gears is connected to the crankshaft of the steam engine and drives the drive gear.
On the other hand, their rotation directions are "" opposite.
The upper driven gear is arranged in a "╪╪" arrangement. It is composed of two left and right gears and a sleeve and is placed on the shaft as a whole. It can move left and right on the shaft. When it moves to the left, the right driven gear and
The driving gear on the right is engaged, and the shaft rotates forward. When the gear on the left engages, the shaft rotates reversely. When it moves to the middle, the two driven gears do not engage with the driving gear, so they stop rotating.
Everyone chatted and discussed, and someone said: "This clutch is good. The driven gear and the output shaft need spline connection, but the speed cannot be too high when adjusting. It is best to stop."
Frederick nodded and had a preliminary exchange of opinions 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."
Katharina said nervously: "Your Excellency, I can definitely do it well!"
Frederick laughed twice and said: "Don't be nervous. You are also a lecturer at Weisenberg University now. Those guys are still students. When they see you, they have to call you teacher. You call me principal 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: "You are not helping me. When calculating profits from this machine, the technical shares will also be calculated 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 surprised, "Did you tell me that besides salary, I can make money from this machine?"
Frederick pointed at Schmidt and the others and said, "You will know just by asking them. Even though they are dressed plainly in front of me now, none of them don't have a gold chain hanging around their neck when they go out to play."
Katherina opened her mouth. She was a young lady from an old aristocratic family. She was very particular about 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 Katherina: "We can't compare with you in this aspect of magic principles, but they are more familiar with the materials than you, so you can communicate with them more."
Katherina nodded. It was well known to the world that Wesen State produced elemental metals.
Frederick discussed with her ideas for 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 chain is connected to both ends of the front wheel axle. When the steering wheel rotates, it drives the turntable. Then the iron chain pulls one front wheel back, and the front wheel turns to that side.
However, the details need to be studied slowly. Today we all took a preliminary breath, and we will gradually study in depth the next day.
