Background
The rotary driving is a full-circle rotary speed reduction transmission mechanism integrated with a driving power source, which takes a rotary support as a transmission driven piece and a mechanism attachment piece, and takes one ring of the inner ring and the outer ring of the rotary support as a transmission driven piece and a connecting base of a driven working part by attaching a driving piece, a driving source and a housing;
when the folding wall crane is used, the rotary drive is arranged on the base of the folding wall crane, so that the folding wall crane can rotate, the folding wall crane needs to bear larger load, and the folding wall crane can generate larger overturning force during lifting, so that the rotary drive has larger load and anti-overturning capacity, however, in actual use, as the ball grooves of the rotary ring are main stress points, the ball grooves and the balls are wearing parts, regular maintenance is needed, but the rotary ring in the existing rotary drive is usually directly arranged in the shell, so that when the ball grooves are damaged, the whole rotary drive needs to be replaced, and the replacement cost is higher.
Therefore, there is a need for an inner race rotary-swivel drive with a large load and a small anti-overturning footprint to overcome the above problems.

In order to solve the problems, the embodiment of the utility model provides an inner ring rotary driving device with small large load anti-overturning occupied space, and the aim of solving the problems in the background technology is fulfilled.
In order to achieve the above purpose, the embodiment of the utility model specifically adopts the following technical scheme: the inner ring rotary driving device with the small large-load anti-overturning occupied space comprises a shell, wherein a rotating ring is rotatably arranged in the shell, a ball groove is formed in the rotating ring, and cylindrical balls are arranged in the ball groove; the inside rotation of shell is provided with the pivot, the outside fixedly connected with worm of pivot, the outside fixedly connected with worm wheel of swivel becket, the worm wheel meshes with the worm.
As a further improvement of the above technical scheme:
the inside of the shell is fixedly connected with a first supporting seat and a second supporting seat through bolts.
Ball grooves are formed in one side of the first supporting seat and one side of the second supporting seat; the first supporting seat is positioned below the rotating ring, and the second supporting seat is positioned at the side part of the rotating ring.
And the shell is fixedly connected with a sealing cover through a bolt.
The embodiment of the utility model has the beneficial effects that:
when in actual use, the first supporting seat and the second supporting seat can be detached from the shell when being replaced, so that the first supporting seat and the second supporting seat can be replaced without replacing the whole, and the replacement cost is reduced.
