[0029] The transmission gears are provided with single-layer gears and double-layer gears, and there are three of them, namely double-layer transmission gear 1, double-layer transmission gear 2, and double-layer transmission gear 3, which are installed on the corresponding bearing holes of the gear box with bearings.

[0030] The double-layer transmission gear 1, double-layer transmission gear 2, and double-layer transmission gear 3, the transmission gear is a double-layer gear, the main body includes a gear shaft, a gear hub, a power input gear layer, and a power output gear layer; the gear shaft is provided with a front end shaft and a rear end shaft, which are respectively arranged at the center positions of the two end faces of the gear hub; the gear shaft is provided with a large shaft body and a bearing mounting shaft body, and the diameter of the large shaft body is larger than the diameter of the bearing mounting shaft body; the gear hub is a cylinder; the tooth layer of the power input gear and the tooth layer of the power output gear are arranged on the side of the gear hub; the tooth of the power input tooth layer is a T-shaped tooth similar to a T-shaped tooth, and the end of the tooth is a cylinder; the tooth thickness of the tooth is smaller than the tooth width in the corresponding tooth groove; the number of teeth of the power output tooth layer is consistent with the number of teeth of the power input tooth layer, the tooth is a rectangular tooth, and the end of the tooth is arc-shaped, and the tooth thickness is smaller than the tooth width in the corresponding tooth groove.

[0031] The power output gear bearing is installed on the corresponding bearing hole of the gear box.

[0032] The power output gear body includes a front end shaft, a rear end shaft, a gear hub, and a power input tooth; the front end shaft and the rear end shaft are respectively arranged at the center positions of the two end faces of the gear hub; the front end shaft is sequentially provided with a bearing mounting shaft body and a large shaft body, and the diameter of the large shaft body is larger than the diameter of the bearing mounting shaft body; the rear end shaft is sequentially provided with a large shaft body, a bearing mounting shaft body, and a power output spline shaft; the gear hub is a cylinder; the power input tooth layer is arranged on the side of the gear hub; the tooth of the power input tooth layer is a T-shaped tooth similar to a tooth, and the end of the tooth is a cylinder; the tooth thickness of the tooth is smaller than the tooth width in the corresponding tooth groove.

[0033] The number of teeth of the layer of teeth that the power input gear, the transmission gear and the power output gear can mesh with each other is the same.

[0034] The teeth of the power input gear can engage with the teeth of the first transmission gear, the teeth of the transmission gears can engage with the teeth of adjacent transmission gears in turn, and the last transmission gear can engage with the teeth of the power output gear.

[0035] The power is input from the power input gear, passes through the transmission gear, and is finally output from the power output gear.

[0036] In order to more intuitively reflect the beneficial transmission effect of the present invention, the gears are driven by each other in conjunction with the accompanying drawings.

[0037] In order to more conveniently and intuitively reflect the size and speed of power input and power output, the power transmission of the teeth that mesh with each other, the number of teeth on the power input gear, transmission gear, and power output gear is consistent; As shown Figure 7 in the figure, when a tooth of the power output tooth layer of the power input gear rotates to a position where it can engage with a tooth of the power input tooth layer of the double-layer transmission gear 1, this position is the engagement point, which clearly shows that the torque length of the power input of the power input gear is equal to the torque length of the power output of the power output gear. The length of the resistance arm on the power output tooth layer of the power input gear is equal to the length of the power arm on the power input tooth layer of the double-layer transmission gear 1. The length of the resistance arm on the power output tooth layer of the double-layer transmission gear 1 is less than the length of the power arm on the power input tooth layer of the double-layer transmission gear 2. The length of the resistance arm on the power input tooth layer of the double-layer transmission gear 2 is equal to the length of the power arm on the power input tooth layer of the double-layer transmission gear 3. The length of the resistance arm on the power output tooth layer of the double-layer transmission gear 3 is less than the length of the power arm on the power input tooth layer of the power output gear; Assume that the length of the power arm of the power input gear is A, and the resistance arm is B; the length of the power arm of the double-layer transmission gear 1 is C, and the resistance arm is D; the length of the power arm of the double-layer transmission gear 2 is E, and the resistance arm is F; the length of the power arm of the double-layer transmission gear 3 is G, and the resistance arm is H; the length of the power arm of the power output gear is I, and the resistance arm is J. Then A = J, B = C, D < E, F = G, H < I. The total length of the power arms is A + C + E + G + I, and the total length of the resistance arms is B + D + F + H + J. For the convenience of calculation, the equal power arms and resistance arms are omitted. Since A = J, B = C, F = G, D < E, H < I, so E + I > D + H. In summary, the total length of the power arms is greater than the total length of the resistance arms, so the output power is greater than the input power.

[0038] As shown Figure 8 in the figure, when a tooth of the power output tooth layer of the power input gear and a tooth of the power input tooth layer of the engaged double-layer transmission gear 1 rotate to be parallel, it also reaches the middle of the distance between the engagement point and the separation point of the tooth engagement, which clearly shows that the torque length of the power input of the power input gear is equal to the torque length of the power output of the power output gear. The length of the resistance arm on the power output tooth layer of the power input gear is less than the length of the power arm on the power input tooth layer of the double-layer transmission gear 1. The length of the resistance arm on the power output tooth layer of the double-layer transmission gear 1 is equal to the length of the power arm on the power input tooth layer of the double-layer transmission gear 2. The length of the resistance arm on the power output tooth layer of the double-layer transmission gear 2 is less than the length of the power arm on the power input tooth layer of the double-layer transmission gear 3. The length of the resistance arm on the power output tooth layer of the double-layer transmission gear 3 is equal to the length of the power arm on the power input tooth layer of the power output gear; Hypothesis: The length of the power arm of the power input gear is A1, and the length of the resistance arm is B1; the length of the power arm of the transmission gear 1 is C1, and the length of the resistance arm is D1; the length of the power arm of the transmission gear 2 is E1, and the length of the resistance arm is F1; the length of the power arm of the transmission gear 3 is G1, and the length of the resistance arm is H1; the length of the power arm of the power output gear is I1, and the length of the resistance arm is J1; then A1 = J1, B1 < C1, D1 = E1, F1 < G1, H1 = I1. The total length of the power arm is A1 + C1 + E1 + G1 + I1, and the total length of the resistance arm is B1 + D1 + F1 + H1 + J1. For the convenience of calculation, the equal power arms and resistance arms are omitted. Since A1 = J1, B1 < C1, D1 = E1, F1 < G1, H1 = I1, then B1 + F1 < C1 + G1. In summary, the total length of the power arm is greater than the total length of the resistance arm. Therefore, the output power is greater than the input power.

[0039] As Fig. 9 shown, when a tooth of the power input gear rotates to a position where it can be separated from the tooth of the engaged transmission gear, this position is the separation point, which clearly shows that the torque length of the power input of the power input gear is equal to the torque length of the power output of the power output gear, and the length of the resistance arm on the power output tooth layer of the power input gear is equal to the length of the power arm on the power input tooth layer of the double-layer transmission gear 1. The length of the resistance arm on the power output tooth layer of the double-layer transmission gear 1 is less than the length of the power arm on the power input tooth layer of the double-layer transmission gear 2. The length of the resistance arm on the power output tooth layer of the double-layer transmission gear 2 is equal to the length of the power arm on the power input tooth layer of the double-layer transmission gear 3. The length of the resistance arm on the power output tooth layer of the double-layer transmission gear 3 is less than the length of the power arm on the power input tooth layer of the power output gear; Hypothesis: The length of the power arm of the power input gear is A2, and the length of the resistance arm is B2; The length of the power arm of the double-layer transmission gear 1 is C2, and the length of the resistance arm is D2; the length of the power arm of the double-layer transmission gear 2 is E2, and the length of the resistance arm is F2; the length of the power arm of the double-layer transmission gear 3 is G2, and the length of the resistance arm is H2; the length of the power arm of the power output gear is I2, and the length of the resistance arm is J2; then A2 = J2, B2 = C2, D2 < E2, F2 = G2, H2 < I2. The total length of the power arm is A2 + C2 + E2 + G2 + I2, and the total length of the resistance arm is B2 + D2 + F2 + H2 + J2. For the convenience of calculation, the equal power arms and resistance arms are omitted. Since A2 = J2, B2 = C2, F2 = G2, D2 < E2, H2 < I2, therefore E2 + I2 > D2 + H2. In summary, the total length of the power arm is greater than the total length of the resistance arm. Therefore, the output power is greater than the input power.

[0040] In summary, the more double-layer transmission gears there are, the greater the output power.

[0041] The power input gear, transmission gear, and power output gear have the same number of teeth in the meshing tooth layers; therefore, the speed of one rotation of the gears is also the same. When the power input gear rotates one axis, the power output gear also rotates one circle.

[0042] The important features of the above-mentioned labor-saving gear transmission machinery are: A relatively small power can output a very large power through the above-mentioned labor-saving gear transmission machinery.

[0043] The speed of the power output gear may be no less than the speed of the power input gear.

[0044] According to the two characteristics of the above-mentioned labor-saving gear transmission machinery, a relatively small-power driving motor drives a relatively large-power generator through a labor-saving gear transmission machinery, and the electricity generated by the relatively large-power generator is transmitted to the electronic control component, which rectifies and stabilizes the transmitted current, and then distributes it to various electronic components and external current transmission ports. The electronic control component also has the function of temporarily storing electrical energy; and the driving motor uses the electricity transmitted to the electronic control component by the battery only when it starts to start. After the driving motor starts, when the electronic control component detects that there is current transmitted from the generator, it preferentially uses the current transmitted by the generator to work, not only no longer using the battery power, but also charging the battery when the electronic control component detects that the battery power drops to a set value; when it is not used for a long time, the battery power is lost, or the battery is damaged, and the driving motor cannot be started normally, the external power supply can be connected to the external power supply through the external power supply line on the electronic control component to start the driving motor; when the driving motor or the generator is damaged and the generator cannot transmit current to the electronic control component, the external power supply can be connected to the external power supply through the external power supply line on the electronic control component to provide current for the household appliance so that the household appliance can be used normally.

[0045] The present invention has the characteristics of strong practicability, high working efficiency and environmental protection, consumes less external power supply, can start the household appliances without external power supply, and has a household appliance power supply method and structure with a built-in generator set.

[0046] The above are merely preferred embodiments for illustration, and any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall fall within the protection scope of the present invention.
