Embodiment 1
[0033] combine image 3 and Figure 4 As shown, the speed regulating mechanism 60 includes a first speed change gear 61 and a second speed change gear 62, wherein the first rotating shaft 20 is pivotally connected to the first speed change gear 61, the second rotating shaft 50 is pivotally connected to the second speed change gear 62, and the first speed change gear 61 is meshed with the second transmission gear 62 . During specific implementation, the first rotating shaft 20 drives the first transmission gear 61 to rotate, and the first transmission gear 61 further drives the second transmission gear 62 meshed with it to rotate; the second transmission gear 62 drives the second rotation shaft 50 to rotate, and then drives the rotor The impeller 30 rotates so that the rotational speed of the rotor impeller 30 is changed under the action of the first speed change gear 61 and the second speed change gear 62 , thereby changing the braking torque of the hydraulic speed reduction ...
Embodiment 2
[0036] Such as Figure 5 As shown, the speed regulating mechanism 60 includes a first speed change gear 61, a second speed change gear 62, a third speed change gear 63, a fourth speed change gear 64 and a third rotating shaft 65, wherein the third rotating shaft 65 is pivotally connected to the third speed changing gear 63 and the fourth speed change gear 64, the first shaft 20 is pivotally connected to the first speed change gear 61, and the first speed change gear 61 is meshed with the third speed change gear 63, the second shaft 50 is pivotally connected to the second speed change gear 62, and the second The transmission gear 62 is engaged with the fourth transmission gear 64 .
[0037] During specific implementation, the first rotating shaft 20 drives the first transmission gear 61 to rotate, and the first transmission gear 61 further drives the third transmission gear 63 meshed with it to rotate; the second transmission gear 62 drives the third rotation shaft 65 to rotate, ...
Embodiment 3
[0040] Such as Figure 6 As shown, the speed regulating mechanism 60 includes a first speed change gear 61, a second speed change gear 62, a third speed change gear 63, a fourth speed change gear 64 and a clutch 66, wherein the first rotating shaft 20 is connected to the first speed change gear 61 and the second speed change gear 61. Three-speed gear 63, the second rotating shaft 50 is connected to the second speed-change gear 62 and the fourth speed-change gear 64, and the first speed-change gear 61 is meshed with the second speed-change gear 62, and the third speed-change gear 63 and the fourth speed-change gear 64 Further, the clutch 66 is installed on the second rotating shaft 50 and is located between the second transmission gear 62 and the fourth transmission gear 64, which can be connected with any of the second transmission gear 62 and the fourth transmission gear 64. One is combined, and it can also be separated from both the second speed change gear 62 and the fourth...
