current technology

Most of the current transmission devices output a dynamic torque by rotating to overcome the resistance torque to perform work and complete the predetermined or set work. Through the transmission of the internal mechanism of the device, the power directly opposes the resistance from the outside and overcomes the internal friction force at the same time, that is, the power must be equal to or greater than the sum of these two forces to work and perform work, so the efficiency of the transmission device will vary. It will have a great impact on the efficiency of the overall device. Effectively improving the working efficiency of the transmission device will effectively improve the working efficiency of the overall mechanical device and reduce energy consumption.

The working method is described below with reference to the diagram. It starts with the effect of external resistance on the mechanical device, and then talks about the role of power.

When the rotation of the gear labeled 4 with a radius of R4 (where R4 = 2R1 = 2R2 = 2R3 = 2R is set) is subjected to an external resistance torque FR4 (set counterclockwise here), the resistance F is transmitted by the gear labeled 4 On the double gear of label 3, label 3 produces a counterclockwise rotation trend on label 6 through the shaft of label 8. This rotation trend makes label 3 transmit force F to the outer gear of the double gear of label 2, by The label 3 itself is subjected to the counterclockwise reaction force F of the label 2.

At this time, the label 3 is subjected to two forces, namely the resistance force F and the reaction force F (both counterclockwise. Since the distance between the label 3 and the central axis of the label 5 is 2R, these two forces produce two forces on the axis of the label 8. Moment: F × 2R and F × 2R, these two moments converge on the connection point between the label 8 and the label 6, so the label 6 receives a counterclockwise moment of F × 2R+F × 2R=4FR.

The distance between the outer gear of the double gear of the label 2 and the central axis of the label 5 is 2R. After the outer gear is subjected to the clockwise thrust F of the gear of the label 3, the axis of the label 2 is also generated on the label 6 through the shaft of the label 7. The rotation trend, but the direction is clockwise; this rotation trend makes the inner gear of the double gear marked 2 transmit the force to the gear marked 1, because the inner gear of the double gear marked 2 is away from the central axis of the marked 5. The distance is 1R, which is half of the distance 2R between the outer gear and the central axis of mark 5. Therefore, the thrust of the inner gear to the gear of mark 1 is doubled to 2F, and the reaction force of mark 1 is 2F, and the direction is clockwise.

At this time, the outer gear of the double gear marked 2 is subjected to the clockwise thrust F of the gear marked 3, and a clockwise torque F×2R=2FR is generated on the shaft marked 7, and the inner gear of the double gear marked 2 is subjected to 2F. Clockwise reaction force, the moment generated on the axis of label 7 is 2F×1R=2FR; these two moments finally converge at the connection point of label 7 and label 6, so label 6 is subjected to 2FR+2FR=4FR. Hour-hand torque.

At this time, the label 6 is subjected to two moments of equal magnitude and opposite directions, and its total torque is zero, and the label 6 is in a static state. The gear of 1 is fixed and stationary, so the double gears marked 2 and 3 are also stationary, and the gear of 4 is also stationary and cannot rotate.

The counterclockwise thrust of the inner gear of the double gear of the label 2 is 2F to the gear of the label 1. Since the gear radius of the label 1 is R1, the counterclockwise torque generated to the label 1 is 2FR1; since the label 1 is fixed at the center of the label 5 On the shaft, the mark 5 is fixed on the external fixing member of the device again, and the 2FR1 torque obtained by this mark 1 is transmitted to the external fixing member of the device and absorbed. Because 2FR1=FR4, that is, the FR4 resistance torque received by the gear with the original number 4 is transmitted through the device mechanism and finally absorbed by the external fixture of the device, and the resistance torque has zero influence on the motion state of the mechanism. No matter how much resisting torque the number 4 receives, the device will not be moved. The reaction of the fixtures outside the device provides a source of confrontation.

The above is the description of the influence of external resistance on the device, and the effect of power is described below.

When a certain power is applied to the label 6 (the direction is clockwise), and the magnitude of the force can overcome the friction force inside the device mechanism, the mechanism in a static state can be rotated, and the label 4 can push the external resistance to move clockwise Get up; the force exerted by this will be far less than the external resistance.

When label 6 gets clockwise power, when it rotates clockwise around the central axis of label 5, the axis of label 7 and the axis of label 8 will also rotate around the central axis of label 5 for one week along with label 6; Since the inner gear of the gear is 1R away from the label 5, it will roll clockwise while meshing with the gear of label 1, that is, rotate clockwise for one cycle (2πR), and revolve around the label 5 clockwise for one cycle (2πR). ); and the outer gear of the double gear of label 2 will also rotate clockwise once (2πR), and at the same time revolve clockwise around label 5; but since the distance between the outer gear and label 5 is 2R, the distance of its revolution is 2π2R . At this time, the double gear of label 3 will be driven by meshing with the outer gear of the double gear of label 2, it will rotate counterclockwise (2πR), and revolve clockwise around label 5, which is also 2π2R. The number 3 and the number 4 mesh with each other, and the result for the number 4 will be the difference between the clockwise rotation of 2π2R and the counterclockwise rotation of 2πR, that is, 2π2R-2πR=2πR, that is, the gear of the number 4 with a radius of 2R (R4) is clockwise. The hour hand turns half a turn.

The above description illustrates a working method: in the operation of the new type of rotating mechanical device, how the external resistance is absorbed and transformed by the external fixing parts of the mechanical device, the power and the external resistance do not have a direct confrontation relationship, and the external resistance is affected by the device. Countermeasures against the reaction of the external fasteners.

According to the above working mode, when the diameters of the gears in the structure adopt different size ratios, the device can produce different effects and functions. I will not list them one by one here.

To sum up, since the external resistance has been absorbed and transformed during the operation of the mechanism, the power does not need to oppose it, but is only used to overcome the frictional force, so that the mechanical efficiency of this new type of mechanical device can be improved.

The newly invented rotating mechanical device can be used in most mechanical devices that rely on rotation to transmit power. If installed on a car, the engine can be made smaller and the oil (electricity) consumption can be reduced on the basis of keeping the original performance unchanged.
