Embodiment 1
[0028] Such as figure 1 As shown, the power end gear 11, the load end gear 31 and the fulcrum gear 41 are directly meshed with the lever gear 21 respectively. An arc is formed, and the fulcrum gear 41 is located in the interval of the arc. In this example, the power end gear 11, the load end gear 31 and the fulcrum gear 41 all rotate counterclockwise, and the lever gear 21 rotates clockwise. The arc is located at figure 1 The lower peripheral area of the middle lever gear 21; the lever gear 21 is provided with external teeth 22 and a central through hole (not marked in the figure), the inner wall circumference of the lever gear 21 is provided with an annular groove 23, and the circumferential edge of the lever positioning wheel 24 is placed The positioning connection is realized in the annular groove 23 , and the power end gear 11 and the load end gear 31 are installed outside the lever gear 21 .
Embodiment 2
[0030] Such as figure 1 As shown, the power end gear 11, the load end gear 31 and the fulcrum gear 41 are directly meshed with the lever gear 21 respectively. An arc is formed, and the fulcrum gear 41 is located in the interval of the arc. In this example, the power end gear 11, the load end gear 31 and the fulcrum gear 41 all rotate clockwise, and the lever gear 21 rotates counterclockwise. The arc is located at figure 2 The upper peripheral area of the middle lever gear 21; the lever gear 21 is provided with external teeth 22 and a central through hole (not marked in the figure), the inner wall circumference of the lever gear 21 is provided with an annular groove 23, and the circumferential edge of the lever positioning wheel 24 is placed The positioning connection is realized in the annular groove 23 , and the power end gear 11 and the load end gear 31 are installed outside the lever gear 21 .
