Preferably, the bearing is a cross roller bearing, the inner ring portion is annular, and the outer ring portion includes an annular main body portion and a fixing portion extending outward from an outer periphery of the main body portion and used for fixing the ring gear.
Further preferably, the height of the body portion is higher than the height of the inner ring portion.
Further preferably, the rotating device further includes a transition connector connecting the main body and the rotating table, and the transition connector is disposed at an upper portion of the main body in a circular ring shape.
Further preferably, the gear ring comprises a plurality of racks which are arranged in a tail-end connection mode, and the racks are respectively connected with the fixing portion and then enclose into a circular ring shape.
Further preferably, the rack is detachably connected with the fixing portion.
Further preferably, a gap is provided between adjacent two of the racks, and the gap is located at a bottom of the tooth bottom of the gear ring.
Preferably, the motor is a servo motor.
Preferably, the motor is connected with the driving wheel through a speed reducer.
Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
because the utility model discloses a ring shape ring gear and through motor drive's drive wheel drive ring gear to the drive revolving stage rotates, can avoid directly to drive through the motor shaft, thereby reduced the requirement of motor moment of torsion, increased the heavy burden ability that detects the revolving stage, reduced manufacturing cost, increased rotating device's stability simultaneously.
Drawings
Fig. 1 is a schematic perspective view of a rotating device according to an embodiment.
In the above drawings: 1. a bearing; 11. an outer ring portion; 11a, a body portion; 11b, a fixing part; 12. an inner ring portion; 2. a ring gear; 3. a motor; 4. a drive wheel; 5. a transition piece.
Detailed Description
The invention will be further described with reference to the embodiments shown in the drawings to which:
referring to fig. 1, an inspection rotary table for a liquid crystal panel includes a base (not shown), a rotating unit disposed on an upper portion of the base, and a rotary table (not shown) disposed on the rotating unit and rotatably coupled to the base, the rotating unit including a bearing 1 having an outer ring portion 11 and an inner ring portion 12, an annular ring gear 2 fixedly disposed on the outer ring portion 11, a motor 3 disposed on the base, and a driving wheel 4 disposed on the base and engaged with the ring gear 2 by the motor 3, the inner ring portion 12 being fixedly coupled to the base, and the outer ring portion 11 being fixedly coupled to the rotary table.
In the present embodiment, the bearing 1 is a cross roller bearing, the inner ring portion 12 is annular, and the outer ring portion 11 includes an annular main body portion 11a and a fixing portion 11b extending outward from the outer periphery of the main body portion 11a and fixing the ring gear 2.
The height of the body 11a is higher than that of the inner ring 12.
The rotating device further includes a transition piece 5 connecting the main body 11a and the rotating table, and the transition piece 5 is disposed in an annular shape on the upper portion of the main body 11 a.
The ring gear 2 includes a plurality of 21 that are arranged in a final connection, and the plurality of 21 are respectively connected with the fixing portion 11b and then enclose a circular ring shape. 21 are detachably connected to the fixing portion 11 b.
Gaps are formed between adjacent pairs 21, and the gaps are located at the bottom of the tooth grooves of the ring gear 2.
In this embodiment, the motor 3 is a servo motor, and the motor 3 is connected to the driving wheel 4 through a speed reducer.
Because the utility model discloses a ring shape ring gear 2 and 4 drive ring gears 2 of drive wheel through motor 3 driven to the drive revolving stage rotates, can avoid directly driving through motor 3 axle, thereby reduced the requirement of motor 3 moment of torsion, increased the heavy burden ability that detects the revolving stage, reduced manufacturing cost, increased rotating device's stability simultaneously.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
