Connect, the inner ring of the bearing group is fixedly connected with screw mandrel, the screw mandrel forms worm drive pair with nut；
The nut is fixedly connected with the upper end of nut case, and the lower end of the nut case is fixedly connected with lower lift ring；
The opposite side of the planet carrier endoporus is fixedly connected with the upper end of the screw mandrel, and the planet carrier periphery is provided with multiple
Hole, each hole is fixedly connected with the lower end of planet wheel spindle respectively, the upper end of the planet wheel spindle and the inner ring of planet wheel bearing
Connection, the outer ring of the planet wheel bearing is connected with planetary gear, and the external tooth of the planetary gear is formed with the internal tooth of the external toothing
Meshed transmission gear pair.
Further, the planet carrier periphery is symmetrically provided with several holes.
Compared with prior art, the beneficial effects of the invention are as follows：
Using motor as active control elements, the power output of container is used in regulation to the present invention, so as to adapt to the vibration of change
Input, widens the use field of used container, and the used appearance coefficient of used container for overcoming fixed structure is constant, it is impossible to adapt to shaking for change
The defect of dynamic input；The present invention also produces effect of inertia using planet flywheel group, and the revolution and rotation by planet circular system are dual
Motion, effectively improves the used appearance coefficient of used container, overcomes the used coefficient that holds of the used container of single flywheel ball-screw smaller and limited
The defect of system.

Specific embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figures 2 and 3, the used container of active control type of the invention, upper lift ring 1 is fixed with the upper end of motor case 2 and connected
Connect, the lower end of motor case 2 is fixedly connected with the upper end of external toothing 4, the shell of motor 3 is fixedly connected with the upper end of external toothing 4.Rotor
5 are fixedly connected with the side of the endoporus of planet carrier 13.
The upper end of bearing block 7 is fixedly connected with external toothing 4, and the endoporus of bearing block 7 is fixedly connected with the outer ring of bearing group 8,
The inner ring of bearing group 8 is fixedly connected with screw mandrel 9, and screw mandrel 9 forms worm drive pair with nut 11.
Nut 11 is fixedly connected with the upper end of nut case 10, and the lower end of nut case 10 is fixedly connected with lower lift ring 12.
The opposite side of the endoporus of planet carrier 13 is fixedly connected with the upper end of screw mandrel 9, and there are several holes the periphery of planet carrier 13, each hole
