When in use, a spring for pulling apart is provided between the force point shaft 209 and the hidden shaft 206 .

Next, I want to talk about the source of the force that drives the power machine. The power of the power machine comes from the internal force. In this embodiment, the spring tension is derived from the external force split from the internal force, and it comes from eliminating one and a half of the external forces. The resulting torque difference can drive the power machine to rotate.

In this embodiment, the data of the central fixed large gear 11 is: module 2, number of teeth 150, index circle 300mm, index circle radius 150mm, thickness 32mm.

The circumferential gear 204, the circumferential transmission gear 202, and the power gear 203 are all equipped with bearings. The data of these three gears are: module 2, number of teeth 20, index circle 40mm, and index circle radius 20mm. Thickness: the circumference transmission gear 202 is 35mm, the circumference gear 204 and the circumference transmission gear 202 are both 15mm.

The purpose of installing the power gear 203 on the hidden shaft 206 is to decompose the force acting on the hidden shaft 206 into two half-forces, and one half-force acts on the meshing point C of the power gear 203 and the circumferential transmission gear 202 , the other half force acts on the meshing point G between the power gear 203 and the central fixed large gear 11, which further eliminates the half force, and actually transfers the half force, and transfers the half force originally acting on the rotating rod to The large gear 11 is fixed in the center.

Pull out the spring, and connect one end of the spring to the hidden shaft 206 and the other end to the force point shaft 209 . When the device is working, the two ends of the spring are pulled apart and connected respectively, so that there is a pulling force on the hidden shaft 206 and a pulling force on the force-bearing point shaft 209. The two pulling forces are equal in magnitude and opposite in direction. Suppose the pulling force on the hidden shaft 206 is P, the pulling force on the bearing point shaft 209 is F, and the pulling force at both ends of the spring is 200N, then P=F=200N.

As shown in Figure 2-3, next look at the force on the axis of the power gear 203. The power gear 203 is installed on the hidden shaft 206. At this time, there is a pulling force of P on the hidden shaft 206, so the axis of the power gear 203 should also be There is a pulling force of P, but since the hidden shaft 206 is a movable shaft, the shaft center of the power gear 203 does not receive any supporting force.

Next, look at the force on both ends of the power gear 203. Since one end of the power gear 203 meshes with the central fixed large gear 11, the meshing point is G point, and the other end meshes with the circumferential transmission gear 202, and the meshing point is C. The power gear 203 After the axis is acted by the P force, the P force of the axis center of the power gear 203 is decomposed into two 1/2P forces and act on the G point and the C point respectively. Since the G point is the meshing point between the power gear 203 and the central fixed large gear 11, the downward force of 1/2P on the G point is always supported by the G point gear of the central fixed large gear 11, that is to say, the 1/2P The force of is canceled, or eliminated, so the 1/2P force at the G point does no work on the device.

Next, look at point C. Point C is the meshing point of the power gear 203 and the circumferential transmission gear 202, and is also the meshing point of the circular transmission gear 202 and the circular gear 204. Through the meshing of these three gears, the final force of 1/2P Acting on the circumferential gear 204, it performs negative work on the power machine.

Next, look at the force and work of the device: due to the existence of the point axis 215, the force direction on the force point axis 209 and the hidden axis 206 can be changed, which is convenient for the calculation of the force in the analysis and reasoning. It may be assumed that the force point The pulling force on the shaft 209 is the direction F and the line connecting the force point axis 209 to the center of the central fixed large gear 11 is perpendicular, and the force direction on the hidden shaft 206 is the line connecting the hidden shaft 206 to the center of the central fixed large gear 11 vertical. When the axial distance from the force point axis 209 to the central fixed main shaft is 0.17m, which is close to the actual distance, and the force on the force point axis 209 is 200N, it has been proved before that positive work is done, then Wf=0.17×200=34J , set the distance from point C to the center of the fixed spindle axis to be 0.19m, which is close to the actual distance, and the force on point C is 100N. It has been proved before that for negative work, then Wp=0.19×100=19J, positive work and negative work Subtracting work, then Wf-Wp=34-19=15J. Therefore, the unit power mechanism 2 will make a circular motion around the central fixed large gear 11 in a clockwise direction, that is, the device converts the internal force exerted by the spring on the hidden shaft 206 and the force point shaft 209 into a movement around the central fixed large gear 11. External force in circular motion.

If the power machine rotates 12 times per second, the power of the power machine per second is 15×3.14×12=1130W. If the power machine is installed with 16 unit power mechanisms 2, then the power of the power machine is 1130×16=10800W. If a first-level lever is used, The action of the doubling force of the secondary lever, then the power of the power machine will be doubled.

To sum up, the theory of the power machine and the working principle, scheme and structure of the power machine are summarized as follows: The principle of the power machine is divided into 4 steps: 1. Apply a pair of internal forces in opposite directions; 2. Split the internal force into two external forces; 3. Eliminate one of them 1 and a half force in the external force; ④ After eliminating the half force, a moment difference is formed, specifically:

① First, apply a pair of internal forces in opposite directions, in this embodiment, the tension of the spring is used;

② Next, this internal force is split into two external forces, one of which acts on the rotating rod of the power machine to form a moment, this force can be considered as the center force, and the other force acts on the hidden shaft 206 of the power gear 203, due to The power gear 203 makes a circular motion around the central fixed large gear 11, so this force can be considered as a circular force. The central force and the circular force are two forces with different properties. These two forces are equal in magnitude and opposite in direction. To put it simply, one end of the pulled spring is connected to the rotating rod, and the other end is connected to the hidden shaft 206 of the power gear 203 .

③ Elimination of half force: the power gear 203 is installed on the hidden shaft 206, the co-located bearing of the positioning lever is installed on the second side shaft 207, one end of the power gear 203 meshes with the central fixed large gear 11, and the other end is engaged with the circular transmission gear 202 In meshing, the force acting on the hidden shaft 206 of the power gear 203, that is, the force on the center of the power gear 203, can be decomposed into two 1/2 forces, that is, two half forces.

One of the half forces acts on the meshing point between the power gear 203 and the central fixed large gear 11, then this half force only acts on the central fixed large gear 11 and has no effect on the rotating rod of the power machine, so this half force is eliminated. This is very important, please pay special attention, this is also the theoretical basis for the establishment of the power machine. The elimination of the half-force mentioned in this application does not mean that the half-force does not exist, but that the half-force is transferred. The half-force originally acting on the rotating rod is transferred to the central fixed large gear 11 to eliminate the half-force. Since the central fixed large gear 11 itself does not rotate and is in a fixed position, according to the principle of acting force and reaction force, this half force is always supported by the gears at the meshing point on the central fixed large gear 11 .

The other half force acts on the meshing point between the power gear 203 and the circumferential transmission gear 202, and then meshes with the circumferential gear 204 through the circumferential transmission gear 202. This half force does negative work on the rotating rod of the power machine.

④ After the half force is eliminated, the moment difference is formed: there is a force F on the rotating rod of the power machine, which is the spring tension, and there is a force P on the invisible shaft of the power gear, which is the spring tension, where F=P, the magnitude of these two forces Equal, opposite direction. After eliminating the half force, the calculation process of the force distance difference of the point on the rotating rod of the power machine is as follows:

The force F acting on the rotating rod, the force arm L is 0.17m, and the moment _is : M=F·L=0.17·F;

After the half force is eliminated, the half force acting on the rotating rod is 1/2P, the moment arm L is 0.19m, and the moment _is : M = 1/2P·L=1/2×0.19·P=1/2×0.19 ·F=0.095·F

The torque difference on the rotating rod is: M _{up -} M _down = 0.17 · F - 0.095 · F = 0.075 · F, this torque can push the power machine rotating rod to rotate, to obtain a larger torque, only need to increase the spring tension, lengthen The center fixed large gear can be 11 index circle radius.

The torque difference formed by the power machine can be expressed by the formula here:

M=1/2R·F

In the formula, F is the force (N), R is the index circle radius (m) of the central fixed large gear 11, and the force F in the formula is the force obtained by converting the internal force into the external force.

In practice, the power that a power machine can generate can be expressed by the following formula:

W=πR·F·n·N

In the formula, F is the force (N), R is the index circle radius (m) of the central fixed large gear 11, n is the rotational speed (r/s), and N is the number of unit power mechanisms.
