DETAILED DESCRIPTION

[0007] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0008] The technical solution of the present invention is: a multi-layer transmission gear body comprises a gear shaft, a gear hub, a power input gear layer, and a power output gear layer.

[0009] 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 front end 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 structure of the rear end shaft is consistent with the rear end shaft.

[0010] The gear hub is a cylinder, and the side surface of the gear hub is provided with a power input gear layer and a power output gear layer.

[0011] The tooth of the power input tooth layer is a T-shaped tooth, and the protrusions on both sides of the end of the tooth are similar to semi-cylinders.

[0012] The number of teeth of the power output tooth layer is consistent with the number of teeth of the power input tooth layer. The teeth are similar to rectangular teeth, and the ends of the teeth are arc-shaped. The tooth thickness in the corresponding tooth groove is smaller than the tooth groove width.

[0013] In order to more intuitively reflect the beneficial transmission effect of the present invention, in conjunction with the accompanying drawings, when the power input gear passes through a multi-layer transmission gear of the present invention, it transmits power to the power output gear, as shown in the figure; In order to more conveniently and intuitively reflect the size of power input and power output, only the transmission of power of the teeth that mesh with each other is demonstrated, and the number of teeth of the power input gear, transmission gear, and power output gear is consistent; like Figure 4As shown 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 multi-layer transmission gear 1, this position is the engagement point, which clearly shows that the length of the power arm of the power input tooth layer of the power input gear is equal to the length of the resistance arm of the power output tooth layer 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 multi-layer transmission gear 1, the length of the resistance arm on the power output tooth layer of the multi-layer transmission gear 1 is less than the length of the power arm of the power input tooth layer of the multi-layer transmission gear 2, the length of the resistance arm on the power input tooth layer of the multi-layer transmission gear 2 is equal to the length of the power arm of the power input tooth layer of the multi-layer transmission gear 3, and the length of the resistance arm on the power output tooth layer of the multi-layer transmission gear 3 is less than the length of the power arm of the power input tooth layer of the power output gear; Assumption: Let the length of the power arm of the power input gear be A, and the resistance arm be B; the length of the power arm of the multi-layer transmission gear 1 be C, and the resistance arm be D; the length of the power arm of the multi-layer transmission gear 2 be E, and the resistance arm be F; the length of the power arm of the multi-layer transmission gear 3 be G, and the resistance arm be H; the length of the power arm of the power output gear be I, and the resistance arm be 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.

[0014] As Figure 5 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 multi-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 of the power input tooth layer of the power input gear is equal to the length of the resistance arm of the power output tooth layer 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 of the power input tooth layer of the multi-layer transmission gear 1, the length of the resistance arm on the power output tooth layer of the multi-layer transmission gear 1 is equal to the length of the power arm of the power input tooth layer of the multi-layer transmission gear 2, the length of the resistance arm on the power output tooth layer of the multi-layer transmission gear 2 is less than the length of the power arm of the power input tooth layer of the multi-layer transmission gear 3, and the length of the resistance arm on the power output tooth layer of the multi-layer transmission gear 3 is equal to the length of the power arm of 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.

[0015] As Figure 6 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 of the power input tooth layer of the power input gear is equal to the length of the resistance arm of the power output tooth layer 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 of the power input tooth layer of the multi-layer transmission gear 1, the length of the resistance arm on the power output tooth layer of the multi-layer transmission gear 1 is less than the length of the power arm of the power input tooth layer of the multi-layer transmission gear 2, the length of the resistance arm on the power output tooth layer of the multi-layer transmission gear 2 is equal to the length of the power arm of the power input tooth layer of the multi-layer transmission gear 3, and the length of the resistance arm on the power output tooth layer of the multi-layer transmission gear 3 is less than the length of the power arm of 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 multi-layer transmission gear 1 is C2, and the length of the resistance arm is D2; the length of the power arm of the multi-layer transmission gear 2 is E2, and the length of the resistance arm is F2; the length of the power arm of the multi-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.

[0016] 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.

[0017] To sum up, the more layers of transmission gears there are, the greater and smoother the output power.

[0018] To sum up, when several multi-layer transmission gears are transmitted together, the output power is always greater than the input power.

[0019] The power input gear, multi-layer 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.

[0020] In summary, in the transmission process using multiple double-layer transmission gears of the present invention, not only the speed of one rotation of the power input gear is consistent with the speed of one rotation of the power output gear, but also the power can be increased.

[0021] 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.
