"Hou Ye, Hou Ye~~"

In the distance, a fast horse galloped towards him, and soon rushed to the edge of the field, and the hemp pole jumped off the horse with excitement on his face.

Chen Xu shook the wet mud on his hands a few times, stood up and said with an unhappy face: "Don't let the horse eat my pepper seedlings, why are you so excited?" ”

The hemp pole hurriedly pulled the horse back a foot away before he said excitedly: "Master Hou, we have found a good way to make bearings, and the marbles will never fall out again after installation!" ”

"Really?" Chen Xu suddenly became excited.

"Really, really, a craftsman stumbled upon a method that could fit a steel bullet of the right size into the inner and outer rings, and there was no gap when turning......"

"Let's go, let's go to the factory!" Chen Xu handed the shovel in his hand to a servant next to him, then washed his hands in the pond, turned over and got on his horse, and took a few guards to follow the hemp pole to the factory.

At present, the pilot plant has been very different from before, the management is still strict, but the planning inside is more orderly, in addition to the ironwork and ironworks, there is an additional glass factory and a bearing factory, and there is also a comprehensive laboratory.

The glassware has begun to make glassware, cups and saucers and lampshades for candles and oil lamps on a large scale, and these made utensils will be placed in the Qinghe store for sale, which is expensive, more expensive than porcelain, mainly because there is great difficulty in the screening of pure quartz sand, and then all glassware is cast by wax method, not to mention the low efficiency and low yield.

Even if it is the simplest flat glass, it is still difficult to manufacture, at present, the glass factory can only pour the glass that is more than square feet, first use the finest mud to naturally advection to become a flat mud fan, and then fill the paraffin wax model, and finally pour in the melted glass juice, cool the fan, because of the uneven heat and cold or thermal insulation measures and other reasons, generally ten pieces can successfully look like four or five pieces, the cost is huge, an apprentice with a helper can successfully make one or two pieces a day, the whole glass factory has a total of less than 20 apprentices, It is not enough to meet the needs of the carriage factory.

However, glass is the same as porcelain, it is a luxury consumer product, the output is low, the price can be higher, and it is not a necessity of life, so Chen Xu does not particularly care, even if he does too much, ordinary people still can't afford to consume, and the transportation of glass products is difficult, and the current sales scope is limited to Xianyang City, and the Qinghe stores elsewhere are not supplied, and they cannot be supplied.

A separate workshop in the comprehensive laboratory, the purpose of which is to manufacture some of the things studied by the Academy of Sciences here, such as the improved thresher and the blank drawing machine are first made here, and the waterwheels and water mills of different sizes are also being improved and designed, and a group of craftsmen of the Academy of Sciences are immersed in it almost all day and night, and the sound of tinkling and banging is constantly coming out, and the mechanical transmission such as chain gears, runners, and connecting rods are studied here.

Chen Xu has come to see twice, and has instructed twice, it looks very lively, all kinds of gears look good, but in fact, the effect is miserable, there is no deep geometric foundation, no parabolic theory, no precision processing instruments and lathes, the gear manufacturing only looks like, there will be a great error between the two gears cast with the same model, that is to say, the size and distance of the gear teeth can not be exactly the same.

As for the bicycle, Chen Xu has not reported much hope in the short term.

At least through a chain to make the perfect linkage of two different gears of the size without errors, this difficulty is not ordinary, far beyond the industrial design and manufacturing capacity of this era, just a chain is enough to torture a group of craftsmen screaming, several craftsmen in charge of the chain in front of the workbench, full of all kinds of large and small iron pieces, bolts and rollers and other things, one o'clock to sit in front of the table with red eyes tinkling banging.

It's not for Chen Xu's reward of 10,000 dollars.

Rather, these people have fallen into a frenzy for high-end machinery such as gears and chains.

It's a different story.

A completely different mechanical world than what I have seen before.

With qualified gears, tight chains, flexible bearings, and some simple processing machinery and equipment manufactured at present, the door of a machine industry seems to have begun to open, because once these things are successfully studied, they will inevitably affect all aspects of life.

As the top group of craftsmen in Daqin, their vision naturally looks deeper and farther.

In the bearing factory, there are hundreds of apprentices and helpers, divided into more than 10 groups, each carrying out different tasks.

Screening and polishing of steel balls, selection, grinding, polishing of collars, and final assembly and testing, all steps are completely completed by hand, and there can be no sloppiness.

Because the bearing is a precision component, the inner and outer collar must be polished very smooth, and the steel ball must also be selected to have the same diameter and size, and it must be guaranteed to be round enough without any defects, otherwise once it is manufactured, it will be unqualified, and it will not take long to break.

A pair of steel bearings is worth a lot of money, if the two ends of the three days break down and cause the carriage to break down on the road, it will inevitably seriously affect the travel and cargo transportation, can not improve the efficiency of the better than with the original wheels.

The steel machinery industry represents progress, not regression.

Therefore, Chen Xu has high requirements for the bearing factory.

One of the main reasons is that most of these bearings were bought by princes and wealthy businessmen.

The poor quality affected the reputation of his immortal disciples.

"Master Hou is here!"

Seeing Chen Xu walking into the factory accompanied by hemp poles, the busy craftsmen and apprentices hurriedly put down the workstations in their hands to salute and greet.

"Leave me alone, go to work!" Chen Xu waved his hand, and the craftsmen and apprentice helpers immediately dispersed, each continuing his work.

Ma Zhuo took Chen Xu to a separate workshop in the factory, where only two craftsmen were measuring steel balls and collars with calipers.

"Excuse me, show me the new and improved bearings!"

Chen Xu was already familiar with these craftsmen, and walked straight to the front of the workbench and looked at the mess of various large and small bearings and steel products on the table.

"Master Hou, look, that's it!" A middle-aged craftsman hurriedly handed Chen Xu a bearing with a diameter of about three inches in front of him.

The appearance is the same as that of ordinary bearings, with eight steel balls in the middle of the inner and outer collars, and no iron plates to block the steel balls have been installed.

Chen Xu flicked it lightly with his hand, and his face couldn't help but move.

"Hey, yes, yes, it's flexible, there's no gap!"

Looking at the whirring bearing, Chen Xu couldn't help but praise repeatedly, and at the same time looked at the bearing carefully, and found that the steel marble and the inner and outer collar were very tightly informed, and there was no loose feeling before, and there was almost no difference from the bearing he played with when he was a child.

"How did the steel marble get in?" After looking at it, Chen Xu couldn't help but ask in surprise.

"Hehe, it's actually very simple, just hammer it and go in!" Hehe said with a giggle next to him.

"Hammer it in, isn't it a steel bullet to be deformed?" Chen Xu looked at the hemp pole suspiciously.

"No, no, Hou Ye is wrong, it's not to hammer the steel marble in, but to hammer the outer ring, you only need to put the steel marble in first, and then hammer the collar vertically, and these steel marbles will be embedded and arranged neatly!" A craftsman quickly shook his head and explained.

Chen Xu stayed for a long time and didn't figure out how to hammer the steel bullets hard to be able to run in and arrange them by himself, so he pointed to the craftsman and said, "You show me a demonstration!" ”

"Yes, Master Hou!"

The craftsman excitedly swept the pile of things in front of him to the side, then picked up a set of polished collars, and held the inner and outer rings up with one hand, one side of the inner and outer rings touched, and the other side left a lot of space.

"Master Hou, the first step is the same as our usual assembly of bearings, put these marbles in first......"

As he spoke, the craftsman used his other hand to pick up the steel marbles that had been polished and selected from a nearby wooden bowl, and filled them one by one into the staggered gaps between the rings, filling them with a full eight pieces, but all of them were concentrated on one side.

"Master Hou is optimistic!" The craftsman picked up a wooden hammer and smashed it against the collar that had been erected.

"Bang~"

The things on the entire workbench vibrate, the craftsman put down the hammer and lifted the bearing, and what appeared in Chen Xu's eyes was indeed a perfect bearing with marbles arranged neatly, and the inner and outer rings were tightly fitted, and the steel bullets were not loose in the groove between the two collars.

Chen Xu grabbed the inner and outer coat rings with his hands and broke them a few times, and found that they were very strong and could not be disassembled by brute force at all.

It's really a dog, what the hell is this?

Is the bearing also afraid of being beaten?

Chen Xu felt the chaos in his head at the bearing, which was perfectly successful with a hammer, and after looking at it for a long time, he put it down and said, "Let Ben Hou assemble one and try it!" ”

The craftsman immediately got out of the way and handed Chen Xu a pair of polished collars, Chen Xu also erected and held the collar with one hand, and the other was to fill it with steel marbles, and after filling it, the craftsman carefully advised: "Master Hou, use two fingers to lift the middle collar slightly upward, and then use a wooden hammer to smash the top hard, be careful not to hit the hand......"

Chen Xu nodded, picked up the wooden hammer and took a breath and smashed it against the collar, with a bang, Chen Xu felt that his left hand was slightly loosened, and when he picked up the bearing, he found that sure enough, the steel bullets inside had all been neatly embedded between the inner and outer collars.

"I see, I see~" Chen Xu finally understood how these steel bullets ran into it by themselves at this time.

Originally, there was enough space between the inner and outer collar rings, but they were all on one side when they were filled in, but the violent beating of the outer ring caused the outer ring to have an elliptical deformation in an instant, so that the steel bullets sandwiched on both sides fell down at the moment of deformation to fill the gaps extruded, and then the deformed outer ring instantly rebounded to return to its original shape, and under the common extrusion of the inner and outer rings, the only steel bullet that could roll was perfectly embedded in.
