Chapter 10, Shaft Sleeve Connection

Indeed. Today I need to show the drawings to the teacher..." Shulan exclaimed with a sigh, saying, "I’m sorry, I have to go to the design institute.

It was not done by me. Look, if there is only this diagram, is it easy to calculate the data? Liang Jianguo is a vocational school graduate from his early years; he used to be able to perform calculations, but as he has aged, he rarely calculates by himself now

However, the widespread adoption of such technology will take another 10 to 20 years, after most machinery has been updated. What is being said in Su City now clearly dampens people's enthusiasm.

"He is capable of calculating torque and transferring loads, not inferior to the university students in our institute, and moreover, his design is quite innovative." Liang Jianguo shouted back, "Xiao Wu, come here and draw this schematic for us to take a look."

I work in an oil extraction team. Su City

Then it involves torque. You say you are a worker? Liang Jianguo was somewhat skeptical.

In the early heavy machinery, the connection between the gearbox shaft and the gear was typically achieved through an interference fit. During maintenance, once the gear and shaft are disassembled, the connection fails, rendering repair meaningless. If reprocessing is required, the quality of assembly and connection cannot be guaranteed. For instance, in oilfield sites, the large gear is usually replaced; due to the interference fit, maintenance workers are forced to replace both the gear and the shaft, resulting in significant losses. If a sleeve connection is used, only the gear needs to be reprocessed, which naturally reduces maintenance costs.

At the same time, another thought crossed my mind: having developed so well, I am actually not small anymore

... ...

However, Liang Jianguo is a seasoned technician in the oil field, leading his team in design research every day, which allows him to casually assign a topic to the students in his class

However, his gaze quickly drifted away from the blueprint, and he pointed to the adjacent diagram, asking: "Did you draw this?"

Hello, you are impressive. My name is hetushucom.com Shulan, and I am from Shengli Petroleum School. What about you? The girl graciously extended her hand, her face glowing with a hint of pink

Of course, heavy machinery such as coal and oil mining equipment prefers to use sleeve couplings. Su Cheng realized only after speaking that it was now 1987

Liang Jianguo simulated it on his hand and sighed, "This is indeed a good design, but it is drawn too simply, and various parameters are not indicated, making it difficult to assess"

Can you show it to me

Which oil extraction team is it from

Xiao Wu stared at the blueprint for a while and said, "It's a bit difficult; I estimate it will take about ten days to half a month. We also have quite a few tasks at hand; otherwise, we could call a few more people to join us."

Have you seen other types of shaft sleeve connections

A connected design diagram is quite simple, primarily consisting of gears and shafts, along with the relationship of a middleware.

She spoke as she unfolded the blueprint

"Did you really see it?" The young girl, completely unguarded, wore an expression of astonishment

Liang Jianguo uttered a soft "hm" and, putting on his reading glasses, began to examine the book with great seriousness

"You go ahead, I will read for a while longer before leaving." Su Cheng watched Shu Lan leave the library, feeling a wave of heat wash over him. He slapped his forehead hard and thought to himself: What am I thinking? She is still so young.

Without considering the proportional relationship, Su Cheng quickly sketched a diagram and said, "The frictional force for transmitting the load needs to be calculated, it should be approximately like this"

Shulan suddenly jumped up like a white rabbit and said, "I will go find him"

Su Cheng smiled and said, "I usually enjoy reading. Are you also about to graduate from school?"

"Yes, I remember he said that the friction of the payload needs to be calculated," Shulan thought, tilting her head.

This ... ... is hard for Shulan to articulate

The little girl indeed lowered her head in disappointment and said, "I knew such an invention already existed"

Su Cheng hesitated for a moment, took out a pencil, and sketched a diagram of the expansion sleeve connection in the corner of the drawing. This was a relatively advanced type of shaft sleeve connection during his school years, yet its essence was quite simple, still relying on pre-tightening screws and connecting sleeves to create friction between the shaft and the connected component

Xiao Wu is also 30 years old. In just a few moments, he completed the drawing and brought it over, exclaiming: "Old Liang, your design is exquisite! If we could replace our equipment with this, we could save quite a bit of money each year"

"Master Liang, how could I dare?" At this moment, Shulan was much more lively, running to the experimental table with the blueprints in her arms, and said with a smile, "I went to the library this morning to look up information, but there are still many things I don't understand"

Her teacher, Liang Jianguo, works at the research institute and only goes to school for classes two days a week

Of course, for example... the expansion sleeve connection. Su Cheng thought of a connection method that should not exist now

Seeing Shulan sneak in quietly, Liang Jianguo chuckled silently and exclaimed, "What, are you taking advantage of my old eyes?"

Similar to the Oil Extraction Command Center of the East China Sea, the Research Institute at https://wwwhetushu.com is also a secondary unit of the Shengli Oilfield. It holds an equivalent status to the Geological Science Research Institute, the Drilling and Oil Extraction Technology Research Institute, Shengli Petroleum School, Shengli Health School, Normal College, Employee Training College, Oilfield Party School, Central Hospital, Wuqishi School, Shengli Hospital, Yantai Sanatorium, and Cadre Rest Home, among others. It can be considered one of the relatively less busy positions within the logistics department, although it also wields less power.

Shulan walked briskly to the Design Planning Research Institute

Su Cheng quickly remedied the situation, saying: "I have never seen this type of connection you designed. There are many kinds of shaft sleeve connections, and as long as they are not repetitive, they are all new inventions"

There are also people in my family working in the oil extraction team, but none as impressive as you. Upon hearing that he was a worker, Shulan immediately felt a strong affinity and her tone became a bit more cordial

No, it is a worker I met in the library who drew it

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

Shulan affirmed, "Yes, he said it is from the oil extraction team."
