Chapter 226 (2/2)

After all, in this era, there are no bearings on the waterwheel built by Europeans. The main shaft of the waterwheel and the supporting bearing bush of the waterwheel frame are hard ground. Even Europeans add various kinds of grease to reduce the friction, but it is hard ground.

Jack Williams' improved cylindrical roller bearing is ready to be used on the main shaft of the two water tankers erected by gaoshu tribe.

The two large cylindrical roller bearings will be stuck on the cast bearing frame, and the bearing frame will be fixed on the support frame of the waterwheel. Then when the waterwheel turns, the main shaft of the waterwheel will drive the bearing to rotate, instead of grinding with the bearing bush.

The speed of waterwheel is not fast, and the size of this kind of cylindrical roller bearing is relatively large, so even if there are some errors in the cylindrical roller, after adding grease, this error is also within the acceptable range.

Especially after the use of bearings, there is less huge friction between the main shaft and the support frame of the water truck, and the work efficiency of the water truck will be greatly improved.

Once the waterwheel is built, through the transmission of gears, a waterwheel can drive several workpieces to work at the same time.

At that time, the crushing of materials, which requires a lot of manpower or animal power and lasts for a long time, can be completely handed over to the water driven grinding plate, and only one or two people need to take care of it, which can greatly liberate manpower.

Also useful blast furnace smelting iron must blast equipment - bellows, can also be handed over to hydraulic drive. With gear transmission and bearing, we can make more efficient crankshaft for transmission.

All in all, once the two water tankers are built and tested successfully, it can be predicted that more water tankers will be erected along the litterliver river bank to the west of the gaoshu tribe. On the banks of the frenchbrod river near the original big green hill tribe, more water tankers will also be erected.

In the future, Daqingshan tribe will become the metallurgical base of gaoshu tribe, which has been planned by stone bear for a long time. The waterwheel will play a bigger role there.

Jean Agust's work is almost done. It's not difficult for him to burn glass. Now in a new wooden house built in the middle of the high tree tribe, a lot of bottles, jars and experimental equipment have been piled up.

And under the guidance of Agust, many of the tribe's people have been able to burn and blow glass. Next, this elementary laboratory will be able to carry out various chemical experiments.

Brother gaigai's cement firing has also achieved preliminary results. In the case of stone bear's golden finger, firing cement is not difficult.

It's like the big pond that David Dean built north of the tribe, which has been made of newly baked cement.

This big pool is specially used for soaking wood. The raw materials for paper-making will be soaked in this large pool for dozens of days before the next processing procedure can be carried out, so the cigarette will not be thought of in the last two months at least.

However, once the success of paper-making, then you can continue to produce cigarettes.

What makes stone bear most happy is not the work that has made progress. What makes him most happy is the crops that are full of vitality in the vast farmland on both sides of the litterliver Rive
