[ detailed description ] embodiments

In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.

Please refer to fig. 1-4, the utility model provides an improved generation carousel mechanism, it includes inner ring 1, first outer loop 2 and second outer loop 3, first outer loop 2 is located the top of second outer loop 3 and does not contact each other, is equipped with a plurality of first balls 4 between first outer loop 2 and the inner ring 1, and first outer loop 2 can rotate for inner ring 1 with the help of first ball 4, be equipped with a plurality of second balls 5 between second outer loop 3 and the inner ring 1, and second outer loop 3 can rotate for inner ring 1 with the help of second ball 5, install interior ring gear 6 on the medial surface of inner ring 1, interior ring gear 6 is used for connecting driving motor 7, drives inner ring 1 through driving motor 7 and rotates.

The working principle is as follows: taking the second outer ring 3 as an example, the first outer ring 2 can rotate relative to the inner ring 1, and the inner ring 1 can also rotate relative to the second outer ring 3, by fixing the dining table panel on the first outer ring 2, after the driving motor 7 is started, the driving motor 7 shell drives the inner ring 1 to rotate relative to the second outer ring 3, and the dining table panel has a certain weight, so that the first outer ring 2 and the first balls 4 generate a larger friction force, the first outer ring 2 and the inner ring 1 rotate synchronously by using the friction force, when a user rotates the dining table panel with a hand, the rotating force is larger than the friction force generated by the dining table panel, the first outer ring 2 can rotate relative to the inner ring 1, under the action of the first balls 4, even when the first outer ring 2 generates an external force to rotate, the driving motor is not influenced to drive the inner ring 1 to rotate. This carousel mechanism is a whole, can use on needs pivoted product, and application scope is extensive, and the structure is firm, in addition, adopts double-deck ball structure, and driving motor 7 when driving inner ring 1 and rotate, driving motor 7 only need less torsion just can drag first outer ring 2 and rotate, and is concrete, and driving motor 7 only needs the power of exporting 5-7KG, can drive the rotation of second outer ring 3 about 50 KG.

In this embodiment, an annular first mounting groove 21 is disposed on the inner side surface of the first outer ring 2, an annular second mounting groove 31 is disposed on the inner side surface of the second outer ring 3, an annular third mounting groove 11 and an annular fourth mounting groove 12 are disposed on the outer side surface of the inner ring 1, the first mounting groove 21 is matched with the third mounting groove 11 to mount the first ball 4, and the second mounting groove 31 is matched with the fourth mounting groove 12 to mount the second ball 5, which is similar to a bearing, and it should be understood by those skilled in the art that the detailed description thereof will not be provided herein.
