Although the original function of the waterwheel is to draw water, that is, to raise the water from a lower place to a higher place, suitable for taking water from the river to the outside of the riverbank, but with the continuous development of the waterwheel, people Gradually realized that the waterwheel used to draw water is actually a great waste.

　　 The force of the water flow is very strong, and once the waterwheel is turned under the push of the water current, the force generated is also great.

　　 Especially on the main shaft of the waterwheel, because of the moment arm and torque, the force generated by the main shaft of the waterwheel is extremely large.

　　 Even if the thrust of each horizontal plate of the water feeder is only five kilograms of force, then a later calculation formula can be used to roughly calculate the torque of the main shaft of the waterwheel.

　　 Calculated according to the conversion of one kilogram force equal to 9.8 Nm, the spoke length of the waterwheel is five meters, which means that a horizontal plate can bring a torque of 245 Nm to the main shaft.

　　 And the maximum torque of a 2.0-displacement car engine is only about 200 Nm.

　　 Not to mention that there are a total of 16 horizontal boards on this waterwheel...

　　 People in ancient times did not naturally calculate such things as force arms and torque, but this does not prevent people from being able to clearly realize that the main shaft of the waterwheel can actually do a lot of things after it is turned.

　　 So, whether it is China or Europe, in ancient times, waterwheels were used to do more things.

　　 Just like in Europe in this period, it is very common to use water wheels or waterwheels as power. Before Watt successfully improved the steam engine, hydraulic drive was a very important source of power for European countries.

The two waterwheels made by the Gaoshu tribe are experimental, so the diameter of the waterwheel is only about ten meters, and this one can be regarded as a small waterwheel among the waterwheels.

　　 But even for a small waterwheel, it is more than enough to drive other workpieces to perform some work through the rotating main shaft.

　　 A gear with a diameter of about half a meter is fixed at the end of the main shaft of this waterwheel, and this large gear is also cast.

　　Thanks to the formulas for the gear modulus provided by Shixiong to Jack, this gear is made very well.

　　 When the main shaft rotates, it will rotate with this gear. If the rotation speed of the waterwheel is three revolutions per minute, then the rotation speed of the large gear is also this speed.

　　 Three laps per minute, which is a relatively fast speed for a waterwheel, but very slow for mechanical power.

　　 However, this gear as the driving wheel has a large diameter and a large number of teeth, so once a pinion gear meshes with it, the speed of the pinion gear will increase by N times.

　　 can be calculated by applying a very simple calculation formula from later generations.

　　 For example, the large gear as the driving wheel has 72 teeth, and the rotation speed is 3 revolutions per minute. When a driven wheel with 6 teeth meshes with the driving wheel, the driven wheel can reach a speed of 72÷6×6 in one minute.

　　 The speed of 36 revolutions per minute is definitely very slow for a machine, but it is enough for the current Gaoshu tribe.

　　 If the waterwheel wants to drive a big mill to rotate, the speed of 36 revolutions per minute is too fast.

　　 Of course, if you want to get a higher speed, then you need to carry out a two-stage shift.

For example, if the tribe needs a device with five revolutions per second, you can install a shaft in the passive wheel, and install a gear with a larger number of teeth on the other end of the coaxial. This gear will act as a secondary driving wheel, and then Drive another passive wheel with fewer teeth.

　　 As long as the ratio of the number of teeth is calculated, then this waterwheel spindle with three revolutions per minute can drive a workpiece with five revolutions per second, which is 300 revolutions per minute. Even if the number of revolutions is higher, as long as it is not a heavy-duty workpiece, it can still be driven.

　　 Therefore, in order to be able to drive more different workpieces to rotate, Jack designed several gears with different numbers of teeth. These gears are used as passive wheels, and different gears are used to drive them according to the speed requirements of different equipment.

　　 In Shixiong’s plan, the main purpose of the two waterwheels is to experiment. Once the test is successful, the function of the two waterwheels is to draw water and drive stone grinding.

　　 After all, this is the base camp of the Gaoshu tribe, and some industrial matters will not be done here. The Gaoshu tribe is mainly for living and producing food, so the two waterwheels are mainly for drawing water and serving the daily life of the tribe's tribe.

　　 Once these two waterwheels succeed, then a larger diameter and larger number of waterwheels will be erected on the side of the Daqingshan tribe.

　　 As the industrial base of the Gaoshu tribe, the Daqingshan tribe is the place where the most hydraulic power is used.

　　 But this matter can't be rushed. First, get the two waterwheels to work, and the two waterwheels can run for a long time, before they can set up more and larger waterwheels on the Daqingshan tribe.

　　 And if you don’t consider other reasons, in terms of pure power, hydraulic power is actually better than steam engine.

　　 Once the hydraulic power can be developed vigorously, then with this abundant power guarantee, the work in other plans can be slowly unfolded.

　　 For example, water looms and mule looms.

　　 Jack is there, coupled with Shixiong's golden fingers, it is not a problem to come up with these two things. And once Major Jack agrees to establish a textile factory in Europe to promote these two machines at the same time, then in the next few years, UU reading www. uukanshu.com Stone Bear can get some much-needed things from the European continent far and away.

　　 As the later generations will say, the development of industry is driven by the driving force first.

　　 The successful erection of this waterwheel provides the strongest guarantee for the future industrial development of the Gaoshu tribe.

　　 The second waterwheel was erected the next day, and the effect is no different from the first waterwheel.

　　 Two big guys stood by the river, which became a big sight of Gaoshu tribe.

　　 No matter morning or evening, as long as they are free, the tribesmen will come here to admire these two waterwheels that are always spinning tirelessly.

After erecting the two waterwheels, Laomumu and his family led their two sons and other tribesmen to the Daqingshan tribe. Now that the two waterwheels have been successfully erected, their next job is to make them. Larger waterwheel.

　　 Lao Mu’s two grandsons led other tribesmen to build new wooden houses next to the two waterwheels.

　　 These two large wooden houses will be the place where hydraulic millstones will be stored in the future. At present, in addition to drawing water, the biggest function of the two waterwheels is to drive the four big mills, specifically to grind something for the tribesmen in the tribe.

　　Of course, these two waterwheels are also supervised by special personnel, such as adding refined grease to the bearings for lubrication, such as monitoring the operation of the waterwheel.

　　 Anyway, after these two big waterwheels are hypothesized, they have become the treasures of all the people of the Gaoshu tribe...
