The Rise of Heavy Industry 1980

"The radial load of the 608 bearing can meet the requirements of CC20-3, and the axial load is negligible, so that the relationship between speed and torque can be calculated according to the transmission power of 14 kilowatts.

"However, the original design did not take into account the axial preload of the bearing, which is exactly what I call a design flaw. The role of the spring gasket is to provide this preload.

After Wang Chaoyang's explanation was finished, Zong Shiguo reacted for a moment and said: "The spring gasket can provide axial preload, I know this." But bearings require preload, which I've never heard of?"

"No matter how precisely the inner and outer rings of the bearing are matched and the balls are matched, there is a gap. This void is called the axial clearance, and it is ...... during bearing operation Especially in the process of high-speed operation, the axial clearance will greatly affect the service life of the bearing, so the axial clearance must be considered when designing high-speed bearings.

Yan Hengshan frowned and said, "What you said is not a domestic design standard, right?" Otherwise, Zong Shiguo and they would not have heard of it!"

Wang Chaoyang said: "I don't know much about this, but the method I said is really effective, isn't it?"

Wang Chaoyang can only use a variety of rhetoric, because he does not know the era of domestic mechanical design from the beginning of the attention to the axial clearance of the bearing, but he knows that in the high-speed rotation design of later generations, the axial clearance must be considered, and even need to be accurate to the specific preload value.

"Then let's talk about my second question, can the power system reach 360 hours after your improvement?" Yan Hengshan asked again.

"I can't say that!" Wang Chaoyang replied crisply.

"You don't know?" Yan Hengshan raised his eyebrows.

"My purpose this time is to solve the problem of the gearbox, I can ensure that the gearbox can meet the running test for at least 360 hours, and I haven't checked the other parts of the system, of course I don't know!"

After Wang Chaoyang finished speaking, he smiled and asked, "Leader, other parts also need me to check?"

Yan Hengshan tugged at the corners of his mouth and did not speak. In his heart, Yan Hengshan hoped that Wang Chaoyang would check the other parts of the system as well, but he couldn't say this.

Just kidding, as the leader of a large enterprise, there is a team of more than 10 experts under him, but he asks an outsider to help check the design, and it will be very embarrassing to spread the word.

Zong Shiguo saw Yan Hengshan's embarrassing thoughts, and immediately smiled and said: "Chaoyang, you have already come, just take a look, if we can find the problem in advance, it will be of great help to us!"

Wang Chaoyang shrugged his shoulders and said: "I said two big leaders, you are really full and hungry! Our Red Star Factory is about to close down, how can I have the heart to help others...... Unless the leader can do me a favor and solve my worries......

Zong Shiguo suddenly realized: "You don't have to worry about this, just based on your performance today, Director Yan will definitely be able to personally supervise the review of your Red Star Factory! I have communicated with Director Yan in advance about this matter

, and the order letter will be sent to you within three days!" "What about my Santana?"

"Of course Santana will continue to be rationed to you, and I will send Xiaoma to the Nanyang branch factory to pick up the car!"

"Then thank you so much to Director Yan and Director Zong, you don't know, I used to use Santana suddenly, and I really feel lame without a car for a while! It's nearly a three-hour drive from our factory to the province, and it's convenient to go back and forth in the future!" Wang Chaoyang said with a smile.

Yan Hengshan asked: "Now you can check the system

design, right?" Wang Chaoyang said: "Then take the trouble to give me all the design drawings and design documents, and help me prepare an office, I can't read the drawings in the workshop......, right?"

In the next two days, Wang Chaoyang continued to stay in Changhai Agricultural Machinery to verify the design of the entire power system as a "technical consultant".

It is said to be a Xi, but it is also learning.

Wang Chaoyang used to be engaged in aerospace, and he knew the general direction of the vehicle's power system, but he was not familiar with the specific details. Of course, Wang Chaoyang has a very solid theoretical foundation, so even if he learns Xi, his speed is faster than others.

Therefore, agreeing to Yan Hengshan to inspect the design of the system is a help on the one hand, and on the other hand, it is also beneficial to himself.

The verification process lasted for two days, and Wang Chaoyang found two more design omissions, but the problems were not big and would not affect the running test.

During the two-day verification process, most of the calculations Wang Chaoyang asked Fang Yu to help. Wang Chaoyang found that although this Fang Yu was submissive, his computing power was very strong, and he was not even inferior to Zhang Miaomiao.

Before leaving, Wang Chaoyang said to Fang Yu: "Your talent is very good, your basic skills are very solid, what you lack is experience and self-confidence, and you will participate in practical projects as much as possible in the future to accumulate experience." "

Thank you, Brother Chaoyang, I remembered!" Fang Yu nodded heavily.

In the past few days, Fang Yu, as an assistant, has personally experienced Wang Chaoyang's excellence, the depth and breadth of his mastery of mechanical foundations, the overall situation of industrial design, and his familiarity with the system...... He simply worshiped Wang Chaoyang to the point of worship.

At noon that day, Wang Chaoyang was ready to leave.

On the morning of this day, Zong Shiguo had already handed over the order letter from the Red Star Factory to Wang Chaoyang.

On the way back to the Red Star Factory in Santana, Wang Chaoyang couldn't help but hum a little song.

This trip to the provincial capital can be described as fruitful.

On the way back to Hongxing Factory, he had to pass through Nanyang City, and Wang Chaoyang came to Zhang Miaomiao's house by the way. According to the plan, Zhang Miaomiao will return to the Red Star Factory around the tenth day of the new year, and this day is almost over, and he wants to bring back the Red Star Factory flower.

Zhang Miaomiao was very surprised by Wang Chaoyang's sudden arrival, and then after listening to Wang Chaoyang's experience, the Red Star Factory Flower jumped and jumped happily.

Zhang Miaomiao has always been worried about the situation of the Red Star Factory, and now the heart that is hanging can finally fall.

"I'm driving by the road, do you want to go back to Red Star with me today?" Wang Chaoyang asked.

"I'm afraid not right now. Zhang Miaomiao shook her head and said, "My parents went to visit relatives and won't come back until the evening, or you still ......

" "That's easy to do, I'll wait until the evening." Just take a break at your house. Wang Chaoyang said directly.

"......" Zhang Miaomiao actually wanted Wang Chaoyang to go back first, and then she took a car to the Red Star Factory, but she didn't expect Wang Chaoyang to stay at home directly.

Wang Chaoyang was also a guest anyway, and Zhang Miaomiao was embarrassed to give an eviction order, so she had to nod and agree. The two sat face to face in the living room, but they couldn't find a topic for a while, Zhang Miaomiao suddenly felt embarrassed, so she got up and went to boil water and pour tea.

After drinking a few bubbles of tea, the two chatted without a word, and then they heard the door say: "Oh, who parked the car in front of my house, Miao Bao opened the door, and your mother and I are back!".
