Chapter 10: Shaft Sleeve Coupling

"Do you really see it?" The little girl was unsuspecting and surprised.

In an instant, she became worried again and asked, "Have you ever seen such a connection?"

"Of course, heavy machinery such as coal mines and oil like to be connected with shaft sleeves." Su Cheng didn't wake up until he said that it was 1987.

In early heavy machinery, the connection between the gearbox shaft and the gear was usually carried out of a surplus connection. During maintenance, once the gear and shaft are disassembled and the connection fails, the repair significance will be lost. If it is reprocessed, the assembly and connection quality cannot be guaranteed. For example, the oil production machine at the oil field site is usually replaced by large gears. Because of the over-win connection, the maintenance workers have to replace the gears and shafts together, causing great losses. If it is connected with a shaft sleeve, you only need to reprocess the gear, which will naturally reduce the maintenance cost.

However, the popularization of such technology will take 10 or even 20 years later. After most of the machinery is updated, Sucheng will say it now, which obviously has hit their enthusiasm.

The little girl really lowered her head in frustration and said, "I knew that there was such an invention."

Su Cheng quickly remedied: "I have never seen this kind of connection you designed. There are many types of shaft socket couplings. As long as there is no repetition, they are all new inventions.

"Have you ever seen other shaft sleeve couplings?"

"Of course, for example... inflation socket connection." Su Cheng thought of a connection method that should not appear now.

"Can you show me?"

Su Cheng hesitated for a moment, took out a pencil, and drew a schematic diagram of the expansion sleeve connection in the corner of the edge of the drawing. This is also an advanced shaft sleeve connection method when he was in school, but the essence is very simple. It still creates friction between the shaft and the connector by pre-tightening the screw and the connecting sleeve.

Without considering the proportional relationship, Su Cheng drew a schematic diagram with a few strokes and said, "The friction of the transmission load needs to be calculated. It's probably like this."

"You're so awesome. My name is Shu Lan. I'm from Shengli Petroleum School. How about you?" The girl stretched out her hand generously, and her face was pink.

"I work in the oil production team. Su Cheng."

"There is also an oil production team in my family, but it's not as good as you." When Shu Lan heard that he was a worker, she immediately had a good impression and said in a kinder tone.

Su Cheng smiled and said, "I usually like reading. You are at school. Are you about to graduate?

"Yes. Today, I'm going to show the drawings to the teacher..." Shu Lan said, "Sorry, I have to go to the design institute."

"Go ahead. I'll read the book for a while and leave." Su Cheng saw Shu Lan leave the library. He only felt hot all over. He patted his forehead fiercely and said to himself: What are you thinking? He is still small.

At the same time, there is another idea in my mind: the development is so good that it is actually not small.

......

Shulan walked quickly all the way to the Design Planning Research Institute.

Her teacher Liang Jianguo works in the research institute and only goes to school for two days a week.

Like the Gudong Oil Production Headquarters, the Research Institute is also the secondary unit of Shengli Oilfield, together with the Geological Research Institute, the Drilling Oil Production Technology Research Institute, the Shengli Petroleum School, the Shengli Health School, the Normal College, the Staff Training College, the Oilfield Party School, the Central Hospital, the 57th School, the Sheng Cadre rest centers and other equivalent levels are regarded as relatively leisure positions in the logistics department. Of course, there is also less power.

However, Liang Jianguo is a veteran technician in the oil field. He takes the team to do design research every day, so that he can hand over a topic to the students in the class at will.

Seeing Shu Lan crept into the door, Liang Jianguo laughed hoarsely and shouted, "Why, are you blinded by bullying my old man?"

"Master Liang, how dare I." Shu Lan was much more lively at this time. She ran to the experimental table with the drawings in her arms and said with a smile, "I went to the library this morning to check the materials, but there are still a lot of things I don't understand."

She said that she spread out the drawings.

Liang Jianguo said "um", put on his reading glasses, and looked at it carefully.

However, his eyes soon wandered away from the drawing, pointing to the schematic on the side and asking, "Is this what you drew?"

"No, it was painted by a worker I met in the library."

Liang Jianguo simulated it in his hand and sighed, "This is a good design, but the painting is too simple, and various parameters are not marked, so it is not easy to judge."

"Yes, I remember he said that the friction of the transmission load should be calculated." Shu Lan thought with her head side.

"That involves torque. Do you think it's a worker?" Liang Jianguo didn't believe it very much.

Shu Lan affirmed, "Yes, he said it was from the oil production team."

"Which oil production team?"

"This..." Shu Lan couldn't say it.

"It can calculate the torque and transfer load, which is no weaker than the college students in our college, and his design is quite novel." Liang Jianguo roared back, "Xiao Wu, come and draw this schematic diagram."

The design drawing of a connection is quite simple, mainly the relationship between the gear and the shaft, plus a middleware.

Xiaowu is also 30 years old. He drew it in three or twos and two. He took it over and said, "Mr. Liang, your design is exquisite. If you change all our equipment, you can save a lot of money every year."

"I didn't do it. Look, if there is only this drawing of the schematic diagram, is the data easy to calculate? Liang Jianguo was a technical secondary school student in his early years. He used to be able to do calculations. When he got older, he rarely calculated by himself.

Xiao Wu stared at the drawing for a while and said, "It's a little difficult. It's estimated that it will take ten days and a half months. We have a lot of tasks now, otherwise we can call a few more people to come together."

Shu Lan suddenly jumped up like a white rabbit and said, "I'm going to find him."
