[0028] The power output gear bearing is installed on the corresponding bearing hole of the gear box.

[0029] The power output gear is a double-layer gear, and the main body includes a front end shaft, a flange shaft, a gear hub, a power input gear layer, and an oil pump drive gear layer; the front end shaft and the flange 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 flange shaft is sequentially provided with a large shaft body, a bearing mounting shaft body, and a power output flange, and the diameter of the large shaft body is larger than the diameter of the bearing mounting shaft body; the flange is not only provided with a spline shaft hole at the center position, but also with a bolt hole matching the flywheel; the gear hub is a cylinder; the power input gear layer is arranged on the side of the gear hub; the power input gear layer has at least 5 teeth; the tooth 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 less than the tooth width in the corresponding tooth groove.

[0030] The flywheel is installed on the flange of the power output gear and is provided with bolt holes and spline holes matching the flange.

[0031] 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.

[0032] 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.

[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; like Fig. 9As shown, 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 length of the power arm in the power input direction of the power input gear is equal to the length of the resistance arm in the power output direction 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: 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, therefore 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 Fig.10 shown, it can be clearly seen that when a tooth of the power output tooth layer of the power input gear rotates to be parallel to a tooth of the power input tooth layer of the engaged double-layer transmission gear 1, 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 length of the power arm in the power input direction of the power input gear is equal to the length of the resistance arm in the power output direction 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 transmission gear 1 is C1, and the length of the resistance arm is D1; the length of the power arm of transmission gear 2 is E1, and the length of the resistance arm is F1; the length of the power arm of 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 arms is A1 + C1 + E1 + G1 + I1, and the total length of the resistance arms 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 arms is greater than the total length of the resistance arms. Therefore, the output power is greater than the input power.

[0039] As Fig.11 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 length of the power arm in the power input direction of the power input gear is equal to the length of the resistance arm in the power output direction 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 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, and 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 arms is A2 + C2 + E2 + G2 + I2, and the total length of the resistance arms 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, then E2 + I2 > D2 + H2. In summary, the total length of the power arms is greater than the total length of the resistance arms. 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] In summary, in a labor-saving gear transmission machine using the present invention, not only the speed of one rotation of the power input gear and one rotation of the power output gear are consistent, but also the power can be increased.

[0043] 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.
